Alirocumab for the treatment of hypercholesterolemia.
Alirocumab is a human monoclonal antibody inhibiting proprotein convertase subtilisin/kexin type 9 (PCSK9) that is administered by subcutaneous injection every 2 weeks. Area covered: Herein, the authors discuss the background to inhibition of PCSK9 and the pharmacodynamics, pharmacokinetics and clinical trials with alirocumab. Alirocumab produces substantial reductions in low density lipoprotein cholesterol (LDL-C) in patients with and without background statin treatment. The safety profile appears very promising from the relatively short term studies that have been completed but there are some remaining concerns about long term risks of neurocognitive events and developing diabetes. Expert opinion: The profound reduction in LDL-C with alirocumab is most likely to translate into cardiovascular benefits in the ODYSSEY OUTCOMES trial and is unlikely in itself to result in any major adverse effects. The high cost and the current lack of long-term safety and efficacy data will restrict the use of alirocumab to patients who have high cardiovascular risk from established atherosclerotic cardiovascular disease or heterozygous familial hypercholesterolemia and who are unable to achieve LDL-C targets with maximally tolerated dose of statins with or without other lipid-lowering drugs. When further data become available, these indications are likely to be expanded.

[New pharmaceuticals in cardiology. Heart failure, anticoagulation, dyslipidemia].
Three innovative pharmaceuticals which might play an important role in the field of cardiology in the near future were recently tested in large clinical studies. Serelaxin, a vasoactive hormone peptide that is produced during pregnancy, reduces vessel resistance, increases cardiac output, and improves renal function. Lately, it was demonstrated that serelaxin significantly reduces congestion symptoms in patients with acute heart failure. As a secondary endpoint the mortality at day 180 was reduced. Therefore, serelaxin seems to be a promising new drug for the treatment of acute heart failure which might have a prognostic impact. Edoxaban is a selective factor Xa inhibitor, which inhibits thrombin production and thrombus formation. Two recently published studies reported that edoxaban is at least as effective as the vitamin K antagonist warfarin in prevention and treatment of venous thromboembolism and in the prevention of stroke and systemic embolism due to nonvalvular atrial fibrillation. Compared to warfarin, edoxaban significantly exhibited less frequent severe bleeding complications. Edoxaban will probably soon be the fourth new oral anticoagulant available for patients. The serine protease proprotein convertase subtilisin/kexin 9 (PCSK9) reduces the ability of the liver to bind low-density lipoprotein cholesterol (LDL-C) and to remove it from the circulation. Recently, a monoclonal antibody for PCSK9 was developed which induces a LDL-C plasma level reduction up to 73 % and also decreases lipoprotein(a) and apolipoprotein B. PCSK9 inhibition is a promising new mechanism for LDL-C reduction and the corresponding drug will be presumably approved soon by the regulatory authorities.

Basic science review: Statin therapy--Part I: The pleiotropic effects of statins in cardiovascular disease.
3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG CoA-reductase) inhibitors, otherwise known as statins, are currently the medical treatment of choice for hypercholesterolemia. Hypercholesterolemia is a known risk factor for cardiovascular disease, and statin therapy has led to a significant reduction in morbidity and mortality from adverse cardiac events, stroke, and peripheral arterial disease. In addition to achieving a therapeutic decrease in serum cholesterol levels, statin therapy appears to promote other effects that are independent of changes in serum cholesterol. These ''pleiotropic'' effects include attenuation of vascular inflammation, improved endothelial cell function, stabilization of atherosclerotic plaque, decreased vascular smooth muscle cell migration and proliferation, and inhibition of platelet aggregation. This article is part I of a 2-part review, and it focuses on the pleiotropic effects of statins at the cellular level.

Vascular risk factors, cognitive decline, and dementia.
Dementia is one of the most important neurological disorders in the elderly. Aging is associated with a large increase in the prevalence and incidence of degenerative (Alzheimer's disease) and vascular dementia, leading to a devastating loss of autonomy. In view of the increasing longevity of populations worldwide, prevention of dementia has turned into a major public health challenge. In the past decade, several vascular risk factors have been found to be associated with vascular dementia but also Alzheimer's disease. Some longitudinal studies, have found significant associations between hypertension, diabetus mellitus, and metabolic syndrome, assessed at middle age, and dementia. Studies assessing the link between hypercholesterolemia, atrial fibrillation, smoking, and dementia have given more conflicting results. Furthermore, some studies have highlighted the possible protective effect of antihypertensive therapy on cognition and some trials are evaluating the effects of statins and treatments for insulin resistance. Vascular risk factors and their treatments are a promising avenue of research for prevention of dementia, and further long-term, placebo-controlled, randomized studies, need to be performed.

Pharmacological prevention of atherothrombotic events in patients with peripheral arterial disease.
Peripheral arterial disease (PAD) is strongly associated with atherosclerosis in the coronary and carotid arteries, leading to a highly increased incidence of myocardial infarction, ischaemic stroke and cardiovascular death. Fortunately, pharmacological interventions in large clinical trials have been as effective in subgroups of patients with PAD as in subjects with other atherosclerotic disease. Antiplatelet treatment is indicated in virtually all patients with PAD. Aspirin 75-325 mg day(-1) is considered as first-line treatment, and clopidogrel 75 mg day(-1) is an effective alternative. Statin therapy is indicated to achieve a target low-density lipoprotein cholesterol level of < or = 2.5 mmol L(-1) in patients with PAD and there is emerging evidence that even lower levels are beneficial. Lowering of plasma homocysteine by supplementing folic acid, vitamin B(12) and vitamin B(6) is not recommended in patients with mild to moderate hyperhomocysteinaemia in the 12-25 micromol L(-1) range, since it does not reduce the incidence of cardiovascular events. Antihypertensive treatment is indicated to achieve a goal blood pressure of < or = 140/90 mmHg or < or = 130/80 mmHg in the presence of diabetes or chronic kidney disease. All classes of antihypertensive drugs are acceptable for treatment of hypertension in patients with PAD, but angiotensin-converting enzyme inhibitors ramipril or perindopril are especially appropriate because they reduce the incidence of cardiovascular events beyond their blood pressure-lowering effects. Beta-blockers should not be used as first-line antihypertensive treatment. Diabetic patients with PAD should reduce their glycosylated haemoglobin to < or = 7%. In conclusion, pharmacological secondary prevention of cardiovascular morbidity and mortality in patients with PAD should be as comprehensive as that in patients with established coronary or cerebrovascular disease.

Cardiovascular protection paradigms: is change on the horizon?
Recent trials of patients with cardiovascular disease (CVD) have provided a wealth of data regarding diagnosis, risk factors, and treatment. Aggressive risk factor management has been shown to improve patient survival, reduce recurrent events and the need for interventional procedures, and improve the quality of life in patients with known CVD. There have been impressive reductions in blood pressure and low-density lipoprotein cholesterol levels, and improved diabetes control. Medical therapy with options such as angiotensin receptor blockers, angiotensin-converting enzyme inhibitors, and aspirin has been shown to have positive effects. Patients in current trials are more likely to be receiving appropriate treatment upon study entry than were patients in older trials. Changes in the risk profile of high-risk patients have reduced the overall rates of cardiovascular events and will continue to affect outcomes in randomized clinical trials. Such changes should be considered in the design of new clinical trials and in the interpretation of current data.

CD40 ligand: a novel target in the fight against cardiovascular disease.
To discuss the role of CD40 ligand (CD40L) in atherosclerosis and acute coronary syndromes (ACS), as well as describe relevant clinical literature evaluating the effects of pharmacotherapeutic agents on CD40L expression and soluble CD40L levels.. A MEDLINE and EMBASE search (1966-September 2003) was conducted using the key terms CD40, CD40 ligand, platelets, inflammation, and drug therapy. Additional primary literature was identified by reviewing the reference lists of relevant original and review papers.. All articles identified in the search were evaluated, and those deemed relevant were incorporated into the review.. CD40L is a transmembrane protein expressed on T cells, B cells, mast cells, basophils, eosinophils, natural killer cells, macrophages, endothelial cells, vascular smooth muscle cells, and activated platelets. It is also found in plasma as a soluble protein, sCD40L. As a consequence of CD40L binding to its receptor (CD40), several inflammatory processes are initiated. Studies have demonstrated elevated CD40L levels in patients with hypercholesterolemia and ACS, and elevated sCD40L levels have been associated with increased risk of cardiovascular events. Statins, glitazones, glycoprotein IIb/IIIa inhibitors, and clopidogrel have been demonstrated to effectively reduce CD40L levels both in vitro and in vivo. Abciximab has been shown to reduce the occurrence of death or myocardial infarction during 6 months of follow-up in patients with ACS who had the highest levels of sCD40L.. The proinflammatory and procoagulant protein CD40L represents a novel target in the treatment of atherosclerosis and ACS. A number of therapeutic agents have been shown to modulate the expression of CD40L, findings that could have important clinical applications.

A view from Europe.
The pharmacologic approach to coronary protection, defined here as the prevention or delay of sudden death and myocardial infarction (without negatively affecting noncardiac mortality), is critically discussed. The value of pharmacologically treating mild hypertension and mild hypercholesterolemia is questioned, and the need for well-designed, randomized clinical trials with definitive endpoints to determine a drug's cardioprotective capability is emphasized. Based on such studies, it is concluded that some (but perhaps not all) beta-receptor antagonists as well as aspirin have been shown to protect against sudden cardiac death. Trials of thiazide diuretics, calcium antagonists, and angiotensin-converting enzyme inhibitors have not shown a reduction in sudden cardiac death, despite having individual benefits with respect to other aspects of cardiovascular disease. The demonstration that some beta blockers are cardioprotective is discussed in terms of the pathophysiology of sudden cardiac death, and differences in the pharmacokinetic profiles of individual agents.

Combined therapeutic effect of probucol and cilostazol on endothelial function in patients with silent cerebral lacunar infarcts and hypercholesterolemia: a preliminary study.
This study evaluated the efficacy of combined therapy with probucol and cilostazol on endothelial function in silent lacunar cerebral infarcts (SLCI) and mild hypercholesterolemia.. Flow-mediated vasodilatation (FMD) and nitroglycerin-induced vasodilatation (NMD) were measured before and after 4 weeks of combined therapy with probucol (500 mg/day) and cilostazol (200 mg/day) in 34 patients with a mean age of 72 ± 7 years (range 57-80 years) with SLCI, mild hypercholesterolemia (low-density lipoprotein cholesterol >100 mg/dl) and impaired endothelial function (FMD <6%). Patients were randomly allocated to one of the following two treatment groups: (1) aspirin (100 mg/day) with behavioral modifications, such as diet and/or exercise therapy (A group or control group, n = 17), and (2) probucol and cilostazol treatment (PC group, n = 17), also with behavioral modifications.. Although the baseline FMD was not different between the two treatment arms (2.7 ± 1.5 vs. 2.6 ± 1.5%, n.s.), the posttreatment FMD was significantly improved in the PC group (from 2.7 ± 1.5 to 3.5 ± 1.7%, p < 0.05) but not in the A group (from 2.6 ± 1.5 to 2.9 ± 1.4%, n.s.). No differences were observed between baseline and posttreatment NMD in either group. The effects of treatments on lipid profiles were more profound in the PC group.. Combined treatment with probucol and cilostazol resulted in subacute improvement in FMD/endothelial function in patients with SLCI with mild hypercholesterolemia. This combination therapy has the potential to reduce the risk of cardiovascular events via improvements in endothelial function and lipid profiles.

Synergistic effects of exposure to concentrated ambient fine pollution particles and nitrogen dioxide in humans.
Exposure to single pollutants e.g. particulate matter (PM) is associated with adverse health effects, but it does not represent a real world scenario that usually involves multiple pollutants.. Determine if simultaneous exposure to PM and NO₂ results in synergistic interactions.. Healthy young volunteers were exposed to clean air, nitrogen dioxide (NO₂, 0.5 ppm), concentrated fine particles from Chapel Hill air (PM(2.5)CAPs, 89.5 ± 10.7 µg/m³), or NO₂+PM(2.5)CAPs for 2 h. Each subject performed intermittent exercise during the exposure. Parameters of heart rate variability (HRV), changes in repolarization, peripheral blood endpoints and lung function were measured before and 1 and 18 h after exposure. Bronchoalveolar lavage (BAL) was performed 18 h after exposure.. NO₂ exposure alone increased cholesterol and HDL 18 h after exposure, decreased high frequency component of HRV one and 18 h after exposure, decreased QT variability index 1 h after exposure, and increased LDH in BAL fluid. The only significant change with PM(2.5)CAPs was an increase in HDL 1 h after exposure, likely due to the low concentrations of PM(2.5)CAPs in the exposure chamber. Exposure to both NO₂ and PM(2.5)CAPs increased BAL α1-antitrypsin, mean t wave amplitude, the low frequency components of HRV and the LF/HF ratio. These changes were not observed following exposure to NO₂ or PM(2.5)CAPs alone, suggesting possible interactions between the two pollutants.. NO₂ exposure may produce and enhance acute cardiovascular effects of PM(2.5)CAPs. Assessment of health effects by ambient PM should consider its interactions with gaseous copollutants.

Age and gender biases in secondary prevention of coronary heart disease in a Finnish university hospital setting.
Several studies have shown that treatment of coronary heart disease (CHD) does not meet the goals set in recommendations. The aim of this study was to investigate the adequacy of CHD drug treatment and secondary prevention measures, particularly with respect to age and gender biases, in a Finnish university hospital setting.. The participant pool consisted of patients in FINCAVAS (Finnish Cardiovascular Study), which is a cohort study recruiting consecutive patients performing a clinical exercise test at Tampere University Hospital, Tampere, Finland. 802 patients (581 men, 221 women) with a prior diagnosis of CHD recruited between October 2001 and December 2004 were included in the analysis.. Only roughly 12% of both men and women had an optimal risk factor profile. High blood pressure and hypercholesterolaemia were more common in women than in men, whereas smoking was more frequent among men. Men used ACE inhibitors (32.9% vs 20.4%, respectively), beta-adrenoceptor antagonists (80.8% vs 68.3%, respectively) and aspirin (acetylsalicylic acid) [69.7% vs 58.8%, respectively] more frequently than women, but the frequency of use of these medications was also not at the recommended levels in men. Risk factor control is poorer in older than younger age groups.. CHD patients, particularly women, who performed an exercise stress test in a university hospital are suboptimally treated.

Plasma low-density lipoprotein reduction and structural effects on coronary atherosclerotic plaques by atorvastatin as clinically assessed with intravascular ultrasound radio-frequency signal analysis: a randomized prospective study.
Plaque stabilization by statins is important for reduction of cardiovascular events but has not been demonstrated enough in vivo. We examined whether statins clinically alter the structure of coronary atherosclerotic plaques using intravascular ultrasound (IVUS) radio-frequency (RF) signal analysis.. Fifty consecutive patients undergoing percutaneous coronary intervention were enrolled. Intravascular ultrasound radio-frequency signals were acquired from non-percutaneous coronary intervention-targeted echolucent plaques. The patients were randomly assigned into 2 groups: group S (n = 25) taking atorvastatin 10 mg/d and group C (n = 25) as control. After 6-month follow-up, IVUS-RF signals were sampled at the same plaque sites. Several regions of interest were placed on each plaque. Intravascular ultrasound radio-frequency parameters were blindly calculated in all regions of interests (group S, n = 148; group C, n = 191). Targeted plaque volumes were also measured. Those data were compared between baseline and follow-up.. In group S after 6 months, plasma low-density lipoprotein level was significantly decreased (133 +/- 13 to 87 +/- 29 mg/dL, P < .0001), integrated backscatter of IVUS-RF signals was substantially increased (-53.8 +/- 4.5 to -51.2 +/- 4.9 dB, P < .0001), and plaque volume was significantly reduced, whereas no change was demonstrated in group C.. These results suggest that statins alter properties as well as volumes of coronary plaques within 6 months, which may be related to plasma low-density lipoprotein reduction. Intravascular ultrasound radio-frequency signal analysis may be useful to evaluate the effects of drugs on stabilization of coronary atherosclerotic plaques.

Cardiovascular Risk and Risk Factor Management in Type 2 Diabetes Mellitus: A Population-Based Cohort Study Assessing Sex Disparities
With recent changes in the United Kingdom's clinical practice for diabetes mellitus care, contemporary estimates of sex disparities in cardiovascular risk and risk factor management are needed.. In this retrospective cohort study, using the Clinical Practice Research Datalink linked to hospital and death records for people in England, we identified 79 985 patients with incident type 2 diabetes mellitus (T2DM) between 2006 to 2013 matched to 386 547 patients without diabetes mellitus. Sex-stratified Cox models were used to assess cardiovascular risk.. Compared with women without T2DM, women with T2DM had a higher cardiovascular event risk (adjusted hazard ratio, 1.20 [95% confidence interval, 1.12-1.28]) with similar corresponding data in men (hazard ratio, 1.12 [1.06-1.19]), leading to a nonsignificant higher relative risk in women (risk ratio, 1.07 [0.98-1.17]). However, some important sex differences in the management of risk factors were observed. Compared with men with T2DM, women with T2DM were more likely to be obese, hypertensive, and have hypercholesterolemia, but were less likely to be prescribed lipid-lowering medication and angiotensin-converting enzyme inhibitors, especially if they had cardiovascular disease.. Compared with men developing T2DM, women with T2DM do not have a significantly higher relative increase in cardiovascular risk, but ongoing sex disparities in prescribing should prompt heightened efforts to improve the standard and equity of diabetes mellitus care in women and men.

[Therapeutic education in primary cardiovascular prevention: 4 years sustained interest].
Our patient therapeutic education program yields improvements in health after one year. But what can we see after 4 years, when the patient alone is responsible for following the program?. Two hundred and ninety-one patients participated in the first part of our study and were followed during one year. Four years into the ongoing study, we reviewed the progress of the first 200 patients. We compared the already published Risk Factors and Eating Habits scores between the beginning of the study (T0), one year later (T1) and after 4 years (T4).. The Risk Factor score at T0 is 9.5±7.8, moving to 7±7.5 at T1, and then to 6.8±7.8 at T4 (P<0.001 between T0 and T1 and T0 and T4). Endurance physical activities saw the greatest improvement: 0.79±5 at T0, -1.07±4.5 at T1 and -1.61±4.5 at T4 (P<0.001 between T0 and T1 and T0 and T4). The Eating Habits score went from -18.2±7.3 to -22.2±6.4 and then to -23.5±6.4 (P<0.001 between T0 and T1 and T0 and T4). The best results were obtained through increased consumption of whole grains, green vegetables and fish.. The positive results of the progress of risk factors and eating habits, noted after one year, are even greater four years after the end of the therapeutic education program.

Undertreatment of hypertension and hypercholesterolaemia in children and adolescents with type 1 diabetes: long-term follow-up on time trends in the occurrence of cardiovascular disease, risk factors and medications use.
The aims of the present study were, firstly, to evaluate long-term trends in the occurrence and treatment of cardiovascular disease (CVD) risk factors and the occurrence of CVD events in children with type 1 diabetes mellitus (T1DM) and, secondly, to assess the determinants of undertreatment of CVD risk factors.. A retrospective cohort study was conducted in 3728 children (<19 years of age) with T1DM and up to 5 age- and gender-matched diabetes-free children (reference cohort) (n = 18 513) using data from the Clinical Practice Research Datalink (CPRD).. Compared with diabetes-free subjects, children with T1DM had significantly higher annual prevalence rates of CVD risk factors and cardiovascular (CV) medication use 20 years after the onset of diabetes (index date): hypertension: 35.2% vs. 11.4%, P < 0.001; hypercholesterolaemia: 66.7% vs. 7.14%, P < 0.001; and CV medication use: 37.0% vs. 3.6%, P < 0.001. The significant differences between prevalence rates in the two cohorts started from 1 year before the index date. Furthermore, 50% of the children in the T1DM cohort with hypertension and 53% with hypercholesterolaemia remained untreated with CV drugs for a period of 2-5 years during the 20-year follow-up. Age was the only determinant associated with undertreated hypertension in the T1DM cohort.. Children with T1DM had substantially higher prevalence rates of hypertension and hypercholesterolaemia from 1 year before up to 20 years after the onset of diabetes compared with nondiabetics. There is a substantial undertreatment of CVD risk factors with CV drugs. In children with T1DM, screening for CVD risk factors and adequate treatment are of the utmost importance to prevent CVD later in life.

Heart rate reduction with ivabradine promotes shear stress-dependent anti-inflammatory mechanisms in arteries.
Blood flow generates wall shear stress (WSS) which alters endothelial cell (EC) function. Low WSS promotes vascular inflammation and atherosclerosis whereas high uniform WSS is protective. Ivabradine decreases heart rate leading to altered haemodynamics. Besides its cardio-protective effects, ivabradine protects arteries from inflammation and atherosclerosis via unknown mechanisms. We hypothesised that ivabradine protects arteries by increasing WSS to reduce vascular inflammation. Hypercholesterolaemic mice were treated with ivabradine for seven weeks in drinking water or remained untreated as a control. En face immunostaining demonstrated that treatment with ivabradine reduced the expression of pro-inflammatory VCAM-1 (p<0.01) and enhanced the expression of anti-inflammatory eNOS (p<0.01) at the inner curvature of the aorta. We concluded that ivabradine alters EC physiology indirectly via modulation of flow because treatment with ivabradine had no effect in ligated carotid arteries in vivo, and did not influence the basal or TNFα-induced expression of inflammatory (VCAM-1, MCP-1) or protective (eNOS, HMOX1, KLF2, KLF4) genes in cultured EC. We therefore considered whether ivabradine can alter WSS which is a regulator of EC inflammatory activation. Computational fluid dynamics demonstrated that ivabradine treatment reduced heart rate by 20 % and enhanced WSS in the aorta. In conclusion, ivabradine treatment altered haemodynamics in the murine aorta by increasing the magnitude of shear stress. This was accompanied by induction of eNOS and suppression of VCAM-1, whereas ivabradine did not alter EC that could not respond to flow. Thus ivabradine protects arteries by altering local mechanical conditions to trigger an anti-inflammatory response.

Rescuing Impaired Re-endothelialization of Drug-Eluting Stents Using the Hepatocyte Growth Factor.
Current commercially available drug-eluting stents (DESs) are criticized for the problem of stent thrombosis by induced impaired re-endothelialization (RE). The solving of this challenge could be boosted by endothelial progenitor cells (EPCs). The purpose of this study was to examine the effects of hepatocyte growth factor (HGF) on this process.. The abundance and functional capacity of circulating EPC was analyzed by a fluorescence-activated cell sorter and western blot. The in vivo effect of HGF on DES patency, RE, and neointimal formation was investigated in a hypercholesterolemic rabbit model.. HGF efficiently ameliorates the vascular response to stent implantation, and has an important redeeming influence on the deleterious endothelial effects of DES.

Factors associated with early recurrence at the first evaluation of patients with transient ischemic attack.
We aimed to identify factors easily collected at admission in patients with transient ischemic attack (TIA) that were associated with early recurrence, so as to guide clinicians' decision-making about hospitalization in routine practice. From September 2011 to January 2013, all TIA patients who were referred to the University Hospital of Dijon, France, were identified. Vascular risk factors and clinical information were collected. The etiology of the TIA was defined according to the results of complementary examinations performed at admission as follows: large artery atherosclerosis (LAA-TIA) TIA, TIA due to atrial fibrillation (AF-TIA), other causes, and undetermined TIA. Logistic regression analyses were performed to identify factors associated with any recurrence at 48 hours (stroke or TIA). Among the 312 TIA patients, the etiology was LAA-TIA in 33 patients (10.6%), AF-TIA in 57 (18.3%), other causes in 23 (7.3%), and undetermined in 199 (63.8%). Early recurrence rates were 12.1% in patients with LAA-TIA, 5.3% in patients with AF-TIA, 4.3% in patients with another cause of TIA, and 1.0% in patients with undetermined TIA. In multivariable analysis, the LAA etiology was independently associated with early recurrence (odds ratio [OR]: 12.03; 95% confidence interval [CI]: 1.84-78.48, p=0.009). A non-significant trend was also observed for AF-TIA (OR: 3.82; 95% CI: 0.40-36.62, p=0.25) and other causes (OR: 3.73; 95% CI: 0.30-46.26, p=0.31). A simple initial assessment of TIA patients in the emergency room would be helpful in targeting those with a high risk of early recurrence and who therefore need to be hospitalized.

Impact of repeat myocardial revascularization on outcome in patients with silent ischemia after previous revascularization.
This study sought to compare the survival of asymptomatic patients with previous revascularization and ischemia, who subsequently underwent repeat revascularization or medical therapy (MT).. Coronary artery disease is progressive and recurring; thus, stress myocardial perfusion scintigraphy (MPS) is widely used to identify ischemia in patients with previous revascularization.. Of 6,750 patients with previous revascularization undergoing MPS between January 1, 2005, and December 31, 2007, we identified 769 patients (age 67.7 ± 9.5 years; 85% men) who had ischemia and were asymptomatic. A propensity score was developed to express the associations of revascularization. Patients were followed up over a median of 5.7 years (interquartile range: 4.7 to 6.4 years) for all-cause death. A Cox proportional hazards model was used to identify the association of revascularization with all-cause death, with and without adjustment for the propensity score. The model was repeated in propensity-matched groups undergoing MT versus revascularization.. Among 769 patients, 115 (15%) underwent revascularization a median of 13 days (interquartile range: 6 to 31 days) after MPS. There were 142 deaths; mortality with MT and revascularization were 18.3% and 19.1% (p = 0.84). In a Cox proportional hazards model (chi-square test = 89.4) adjusting for baseline characteristics, type of previous revascularization, MPS data, and propensity scores, only age and hypercholesterolemia but not revascularization were associated with mortality. This result was confirmed in a propensity-matched group.. Asymptomatic patients with previous revascularization and inducible ischemia on MPS realize no survival benefit from repeat revascularization. In this group of post-revascularization patients, an ischemia-based treatment strategy did not alter mortality.

[Prevalence and factors related to therapeutic adherence among black African outpatients with stable coronary artery disease in a cardiology department of Dakar in Senegal].
The management of coronary artery disease has made important progress. Adherence to therapeutic measures is a great challenge for improving the long-term prognosis. In this work, we evaluate factors related to therapeutic adherence in black African patients with stable coronary artery disease.. We conducted a survey over three months (February-May 2008) in three cardiology departments in Dakar. We studied the regularity of drug intake, the adherence to the dietary advices and the appointments for consultation as well as the factors related to adherence. Good adherence was defined by a compliance rate greater or equal to 80% and a compliance rate less than 40% defined poor adherence.. We included 105 patients (61 men) with a mean age of 60.67±11.29 years. Good compliance was noted in 56.2% of cases for drug treatment, 42% for dietary advices and 65% for appointments for consultation. A history of acute coronary events (P=0.04), a good knowledge of the disease (P=0.03) and a healthcare (P=0.02) were the factors related to a good adherence to drug treatment, whereas ischemic cardiomyopathy was a factor for poor adherence (P=0.002). Knowledge of coronary disease was the only factor correlated with good adherence to lifestyle (P=0.014).. Therapeutic adherence remains unsatisfactory in Black African patients with stable coronary artery disease, hence the importance of patient education to reach a good adherence for therapeutic, because better adherence improves long-term prognosis of coronary artery disease.

Modelling coronary heart disease mortality in Northern Ireland between 1987 and 2007: broader lessons for prevention.
To quantify how much of the coronary heart disease (CHD) mortality decline in Northern Ireland between 1987 and 2007 could be attributed to medical and surgical treatments and how much to changes in population cardiovascular risk factors.. The IMPACT mortality model was used to integrate data on uptake and effectiveness of cardiological treatments and risk factor trends in the Northern Ireland population between 1987 and 2007. The main data sources were official population and mortality statistics, hospital administration systems, primary care datasets, published trials and meta-analyses, clinical audits, and national surveys. Between 1987 and 2007, CHD mortality rates in Northern Ireland decreased by 52% in men and 60% in women aged 25-84 years. This resulted in 3180 fewer deaths in 2007 than expected if 1987 mortality rates had persisted. Approximately 35% of this decrease was attributed to increased uptake of treatments in individuals and 60% to population risk factor reductions (principally blood pressure, total cholesterol, and smoking); however, these reductions were partially offset by adverse trends in diabetes, physical inactivity, and obesity.. Approximately 60% of the substantial CHD mortality decline in Northern Ireland between 1987 and 2007 was attributable to major cardiovascular risk factor changes and approximately 35% was attributable to treatments. However, adverse trends in diabetes, obesity, and physical inactivity are of major concern.

Effects of clinical and laboratory variables at admission and of in-hospital treatment with cardiovascular drugs on short term prognosis of ischemic stroke. The GIFA study.
No information exists, to our knowledge, about the possible role of cardiovascular drug administration in the acute phase of ischemic stroke and possible effects on stroke outcome. The aim of our study was to evaluate the relationship between in-hospital treatment with cardiovascular drugs in patients with acute ischemic stroke and some outcome indicators.. 1096 subjects enrolled in the GIFA study, who had a main discharge diagnosis of ischemic stroke represent the final sample. Drugs considered for the analysis were the following: ACE-inhibitors (ACEI), angiotensin II receptor blockers (ARBs), statins, calcium-channel-blockers (CCBs), antiplatelet (APL) drugs, antivitamin-k (VKAs), and heparins. As outcome indicators we choose in-hospital mortality, cognitive function evaluated by Hodkinson Abbreviated Mental Test (HAMT), and functional status evaluated by activity daily living (ADL). Indicators of a good outcome were: no in-hospital mortality, HAMT >6 and 0 ADL impaired. Patients with a good outcome showed a higher rate of in-hospital treatment with ACE-inhibitors, calcium-channel blockers and a lower rate of pre-treatment with heparin.. Our study suggests that if a patient with acute ischemic stroke has higher SBP at admission, higher total cholesterol plasma levels, a lower Charlson index and is treated with ACE-inhibitors, calcium channel blockers and antiplatelet drugs, the short term outcome is better in terms of in-hospital mortality and functional indicators such as cognitive and functional performance at discharge.

Influence of different particle processing on hypocholesterolemic and antiatherogenic activities of yam (Dioscorea pseudojaponica) in cholesterol-fed rabbit model.
Nanoparticle processing is implicated in enhancing bioactive or nutritional compound release from raw foods. The aim of the present study was to evaluate whether different particle processing might affect the lipid-lowering activity of Dioscorea pseudojaponica (DP) and to investigate whether DP could be a potential functional food for prevention of atherogenesis. Its possible molecular mechanisms were also evaluated.. The results indicated that 50 mesh-size DP (50 mesh DP) particles exhibited stronger effects than nanoscale DP (nano DP) particles in terms of lowering the level of serum cholesterol as well as reducing the extent of fatty liver and aortic fatty streak. Moreover, both DP particle types, particularly 50 mesh DP, significantly activated AMPK (5'-adenosine monophosphate-activated protein kinase) and deactivated ACC (acetyl-CoA carboxylase), as demonstrated by the increased levels of both enzymes in their phosphorylated form. Coincidently, high-performance liquid chromatography (HPLC) analysis showed a higher content (P < 0.01) of dioscin, a known lipid-lowering compound, in 50 mesh DP than in nano DP.. These results suggest that improper processing conditions will lead to the decomposition of bioactive components in yam. They also demonstrate for the first time that the lipid-lowering mechanisms of DP may occur through the AMPK-ACC pathway.

In vivo comparison of a polymer-free Biolimus A9-eluting stent with a biodegradable polymer-based Biolimus A9 eluting stent and a bare metal stent in balloon denuded and radiated hypercholesterolemic rabbit iliac arteries.
To evaluate the effect of a polymer-free Biolimus A9-eluting stent [BioFreedom (BF)], compared with that of a biodegradable polymer-based Biolimus A9-eluting stent [BioMatrix Flex (BMF)] and a bare metal stent (BMS) in balloon denuded and radiated hypercholesterolemic rabbit iliac arteries.. Rabbits were fed with 1% cholesterol diet (n = 14) for 14 days, both iliac arteries were balloon denuded and radiated, and then rabbits were switched to 0.15% cholesterol diet. After 4 weeks, BF (n = 8), BMF (n = 8), and BMS (n = 8) were deployed in denuded and radiated areas. Four weeks later animals were euthanized, arterial segments were processed for morphometry.. The neointimal area in vessels implanted with BF stents was significantly less than that seen in vessels implanted with BMS (0.90 mm(2) ± 0.14 vs. 1.29 mm(2) ± 0.23, P <0.01). Percent fibrin and fibrin score were higher with BMF stents compared to BMS (P <0.03 and <0.04) and giant cell number was significantly higher with both BMF and BF stents (P < 0.01 for both). Percent endothelialization was significantly higher and % uncovered struts were lower with BMS compared to either BMF or BF stents (P < 0.05 for both).. This study demonstrates that compared to BMS, BF stents significantly decreased neointimal hyperplasia.

Concomitant administration of different doses of simvastatin with ivabradine influence on PAI-1 and heart rate in normo- and hypercholesterolaemic rats.
Ivabradine is a novel heart rate lowering agent that inhibits I(f) ionic current in the sinus node and demonstrates antiischaemic and antianginal activity. The aim of the paper was to investigate the effect its dose-dependent drug-drug interaction with simvastatin inhibitor HMGCo-A has on PAI-1 blood level, heart rate and blood pressure. The experiments were performed in hyper- and normocholesterolemic Wistar rats receiving simvastatin (1 and 20 mg × kg(-1) bw) with ivabradine (10 mg × kg(-1) bw) during a 4-week period. Ivabradine exacerbated the decrease of PAI-1 in normocholesterolemic animals receiving simvastatin at a dose of 1 mg/kg bw and was not observed to have any significant influence on the PAI-1 values in rats receiving 20 mg × kg(-1) bw simvastatin. Ivabradine, coadministered with simvastatin given at a dose of 20 mg × kg(-1) bw, significantly slowed the heart rate in normocholesterolaemic and hypercholesterolaemic groups as compared to the group receiving ivabradine alone. Conclusion. The administration of ivabradine to normocholesterolaemic and hypercholesterolaemic rats receiving simvastatin significantly exacerbated the slowing of heart rate with no effect on blood pressure. The administration of ivabradine has been shown to demonstrate different effects on PAI-1 values depending on lipid disorders.

Nanocarrier for the enhanced bioavailability of a cardiovascular agent: in vitro, pharmacodynamic, pharmacokinetic and stability assessment.
The goals of the current study were to develop and characterize a nanoemulsion of ezetimibe, evaluate its stability, lipid lowering and pharmacokinetic profile. Solubility of the drug was estimated in various oils and surfactants. Existence of nanoemulsion region was confirmed by plotting phase diagrams. Various thermodynamic stability and dispersibility tests were performed on the formulations chosen from phase diagram. Percentage transmittance, refractive index, viscosity, droplet size and zeta potential of the optimized formulations were determined. Dialysis bag method was employed to study the release rate. The formulation selected for bioavailability estimation contained Capryol 90 (10%, v/v), Crempophor EL (11.25%, v/v), Transcutol(®) P (33.75%, v/v), and double distilled water (45%, v/v). The release rate from the nanoemulsion was highly significant (p<0.001) in contrast to the drug suspension. The level of total cholesterol in the group receiving nanoemulsion CF1 was found to be highly significant (p<0.001) in comparison to the group receiving drug suspension. Bioavailability studies in rats revealed superior absorption of ezetimibe from nanoemulsion as compared to the marketed formulation and drug suspension. The shelf life of the nanoemulsion was estimated to be 18.53 months. The present study corroborated nanoemulsion to be a promising choice to improve the bioavailability of ezetimibe.

Vasculoprotective effects of rosiglitazone through modulating renin-angiotensin system in vivo and vitro.
The peroxisome proliferator-activated receptor-γ (PPARγ) agonist rosiglitazone has been suggested to exert cardiovascular protection through the improvement of lipid metabolism, anti-inflammation, anti-proliferation etc. However, whether renin-angiotensin system (RAS) is involved in the vascular protective effects of PPARγ agonists is not fully understood. The present study aimed to investigate the effects of the renin-angiotensin system in vascular protection mediated by PPARγ agonists.. To investigate the actions of the renin-angiotensin system in vascular protection mediated by activation of PPARγ in vivo and in vitro.. Rats were fed a regular diet (n = 8), a cholesterol-rich diet plus methylthiouracil (80 mg/Kg/day, n = 10), a cholesterol-rich diet plus methylthiouracil and rosiglitazone (4 mg/kg/day, n = 10). The rosiglitazone treatment was started from one month after the start of cholesterol-rich diet plus methylthiouracil, and lasted five months. Cultured vascular smooth muscle cells (VSMCs) were pretreated with 1 μmol/L angiotensin II (ANG II) for 6 h and randomly divided into the control group; the ANG II group (1 μmol/L ANG II); the groups respectively treated with different concentration rosiglitazone (20, 30, 50) μmol/L for 12 h; the groups treated with 30 μmol/L rosiglitazone for (6, 12, 24) h. Morphology changes of the aortic tissues were observed by hematoxylin and eosin stain. The VSMC growth was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay. Angiotensin II and expression of angiotensin receptors were determined by radioimmunoassay, reverse transcription polymerase chain reaction (RT-PCR), western blot, and immunohistochemistry.. After 6 months, lipid deposition, VSMC proliferation and migration toward intima were observed in aortic tissues in the rats on a cholesterol-rich diet plus methylthiouracil, while these pathological changes induced by the cholesterol-rich diet were significantly suppressed by rosiglitazone. In addition, VSMC proliferation induced by ANG II was markedly inhibited by rosiglitazone. Rosiglitazone markedly down-regulated expression of angiotensin type 1 receptor (AT1R) and up-regulated expression of angiotensin type 2 receptor (AT2R) in the aortic tissues and ANG II-treated VSMCs.. The present study demonstrated that PPARγ agonist rosiglitazone suppressed ANG II-induced VSMC proliferation in vitro and early atherosclerotic formation evoked by cholesterol-rich diet in vivo. These vasculoprotective effects of rosiglitazone were mediated at least partially by reduction in local tissue ANG II concentration, down-regulation of AT1R expression and up-regulation of AT2R expression both at the mRNA and protein levels.

Effect of L-arginine oral supplementation on response to myocardial infarction in hypercholesterolemic and hypertensive rats.
The well known metabolic functions of L-arginine have been recently increased with the discovery of its role as the substrate for the synthesis of nitric oxide (NO), which has emerged as an endogenous signaling molecule with potential therapeutic implications for cardiovascular disease. Steady-state levels of NO are derived in part from dietary sources. It has been reported that supplementation of L-arginine reduces atherosclerosis in rabbits and reduces the arterial pressure in hypertensive rats. Therefore, we investigated the effect of L-arginine supplementation using a group of induced hypercholesterolemic rats and a group of spontaneously hypertensive rats; the infarcted area in cardiac tissue of both groups was measured during the response to myocardial infarction in the ischemia-reperfusion model. Hypercholesterolemic rats supplemented with 170 mg kg(-1) of L-arginine showed a significant (P Topics: Administration, Oral; Animals; Arginine; Blood Pressure; Cardiovascular Agents; Dietary Supplements; Hypercholesterolemia; Hypertension; Male; Myocardial Infarction; Myocardium; Nitric Oxide; Random Allocation; Rats; Rats, Inbred SHR; Rats, Inbred WKY | 2010 |
Gender differences in the implementation of cardiovascular prevention measures after an acute coronary event.
To compare gender-related lifestyle changes and risk factor management after hospitalisation for a coronary event or revascularisation intervention in Europe.. The EUROASPIRE III survey was carried out in 22 European countries in 2006-2007. Consecutive patients having had a coronary event or revascularisation before the age of 80 were identified. A total of 8966 patients (25.3% women) were interviewed and underwent clinical and biochemical tests at least 6 months after hospital admission. Trends in cardiovascular risk management were assessed on the basis of the 1994-1995, 1999-2000 and 2006-2007 EUROASPIRE surveys.. Female survey participants were generally older and had a lower educational level than male participants (p<0.0001). The prevalences of obesity (p<0.0001), high blood pressure (BP) (p=0.001), elevated low-density lipoprotein (LDL)-cholesterol (p<0.0001) and diabetes (p<0.0001) were significantly higher in women than in men, whereas current smoking (p<0.0001) was significantly more common in men. The use of antihypertensive and antidiabetic drugs (but not that of other drugs) was more common in women than in men. However, BP (p<0.0001), LDL-cholesterol (p<0.0001) and HbA1c (p<0.0001) targets were less often achieved in women than in men. Between 1994 and 2007, cholesterol control improved less in women than in men (interaction: p=0.009), whereas trends in BP control (p=0.32) and glycaemia (p=0.36) were similar for both genders.. The EUROASPIRE III results show that despite similarities in medication exposure, women are less likely than men to achieve BP, LDL-cholesterol and HbA1c targets after a coronary event. This gap did not appear to narrow between 1994 and 2007.

Soy-diet has beneficial effects on cardiovascular parameters that are independent of its lipid effect in male hypercholesterolemic rats.
Diet-induced atherosclerosis is lower in animals fed soy protein. The effects of various soy components have been extensively studied; however, little is known about the effect of crude soybean feeding on hypercholesterolemia-induced cardiovascular changes. This study investigated the effect of soy feeding on cardiovascular parameters in hypercholesterolemic male rats. Total cholesterol (TC), low density lipoprotein (LDL) and high density lipoprotein cholesterol (HDL), and triglyceride (TG) were measured. Rats were randomly assigned to control, high cholesterol (HC, 2% cholesterol) or HC + soy (HC+S) diets. In the HC+S group, rats received HC diet for 10 weeks followed by 2 weeks of soybean feeding. Arterial blood pressure, TC, TG, LDL and HDL were measured. TC, TG and LDL were higher in HC rats and were not significantly reduced by soybean feeding. Soy feeding reversed the HC-induced increase in arterial blood pressure and also restored the impaired vascular responses to acetylcholine in isolated aortic rings. Pre-incubation of HC+S aortic rings with L-NAME (10(-5) M for 20 min) partially reduced the effects of soy on acetylcholine responses, indicating that the beneficial vascular effects of dietary soy are partially mediated via nitric oxide pathway.

Effects of curcumin for preventing restenosis in a hypercholesterolemic rabbit iliac artery stent model.
To evaluate the efficacy of the curcumin-coating stent (CCS) on the inhibition of restenosis in a rabbit iliac artery stent model.. Curcumin, pigment naturally acquired from the rhizome of the plant curcuma longa, is known to have antiproliferative, antimigratory, and anti-inflammatory effects. However, it is still unclear that curcumin can inhibit neointimal proliferation of the injured vessel.. Dose-dependent inhibition of cell growth was observed over a dose range from 10 nM to 10 microM. CCS was prepared by a dip-coating method (high-dose: HD, low-dose: LD). The release profile of the HD CCS showed that drug release persisted until day 21. Scanning electron microscopy of the CCS showed an intact surface of the stent even after expansion. To test the efficacy of CCS in vivo, LD CCS, HD CCS, and bare metal stents (BMS) were implanted in random order in one iliac artery (N = 30 arteries) of male New Zealand White rabbits (N = 15).. After 28 days, the LD and HD CCS groups had a 43% and 55% reduction in the neointimal area, compared with the BMS group (BMS 3.3 +/- 1.0 mm(2), LD 1.9 +/- 0.8 mm(2), and HD 0.9 +/- 0.5 mm(2), P < 0.05). There appeared to be no cytotoxicity related to curcumin at the indicated doses.. Curcumin, a natural compound in the human diet, seems to be a safe and effective candidate drug for use in a drug-eluting stent for the prevention of stent restenosis following angioplasty.

[Coronary heart disease and dyslipdemia - dosing recommendations at beginning and end of treatment].
Secondary prevention in patients with coronary heart disease includes treatment with platelet inhibitors, beta-blockers, ACE inhibitors or AT (1)-blockers, and statins. Initiation of therapy generally does not require a slow gradual dose increase. In treatment naive patients with acute coronary syndromes, administration of a loading dose of aspirin and/or clopidogrel is recommended. To reduce flushing, nicotinic acid should be initiated at low stepwise increasing dosages. beta-blocker therapy should not be stopped acutely in coronary heart disease patients. If beta-blocker therapy has to be terminated, blood pressure should be monitored closely and, if necessary controlled with other medication. Termination of statin therapy in the acute phase after strokes or acute coronary syndromes is associated with increased cardiovascular events and should therefore be avoided.

Rapamycin modulates the eNOS vs. shear stress relationship.
Studies in animals and patients indicate that rapamycin affects vasodilatation differently in outer and inner curvatures of blood vessels. We evaluated in this study whether rapamycin affects endothelial nitric oxide synthase (eNOS) responsiveness to shear stress under normo- and hypercholesteraemic conditions to explain these findings.. Shear stress levels were varied over a large range of values in carotid arteries of transgenic mice expressing human eNOS fused to enhanced green fluorescence protein. The mice were divided into control, low-dose rapamycin (3 microg/kg/day), and high-dose rapamycin (3 mg/kg/day) groups and into normocholesteraemic and hypercholesteraemic (ApoE-/- on high cholesterol diet for 3-4 weeks) groups. The effect of rapamycin treatment on eNOS was evaluated by quantification of eNOS expression and of intracellular protein levels by en face confocal microscopy. A sigmoid curve fit was used to described these data. The efficacy of treatment was confirmed by measurement of rapamycin serum levels (2.0 +/- 0.5 ng/mL), and of p27kip1 expression in vascular tissue (increased by 2.4 +/- 0.5-fold). In control carotid arteries, eNOS expression increased by 1.8 +/- 0.3-fold in response to rapamycin. In the treated vessels, rapamycin reduced maximal eNOS expression at high shear stress levels (>5 Pa) in a dose-dependent way and shifted the sigmoid curve to the right. Hypercholesteraemia had a tendency to increase the leftward shift and the reduction in maximal eNOS expression (P = 0.07).. Rapamycin is associated with high eNOS in low shear regions, i.e. in atherogenic regions, protecting these regions against atherosclerosis, and is associated with a reduction of eNOS at high shear stress affecting vasomotion in these regions.

Atorvastatin therapy associated with improvement in left ventricular remodeling in a case of idiopathic dilated cardiomyopathy.
Statins have pleiotropic effects such as anti-inflammatory and vascular protective effects that would be beneficial for patients with chronic heart failure. This report describes a patient with idiopathic dilated cardiomyopathy and a long-standing history of heart failure that was treated with atorvastatin in addition to conventional therapy that included beta-blockers. Atorvastatin therapy for 12 months was associated with an improvement in cardiac function and improved left ventricular remodeling and peak oxygen consumption. This result suggests that statin therapy may be a potential novel treatment strategy for patients with chronic heart failure.

[PREVENCAT study: control of cardiovascular risk in primary care].
Most studies of cardiovascular risk factors (CVRF) conducted in our environment concentrate in a single CVRF. The PREVENCAT study was designed to estimate the control of CVRF in the population attended in primary care presenting arterial hypertension (HT), type 2 diabetes mellitus (DM2) and/or hypercholesterolemia (HC) as well as to assess the prevalence of Metabolic Syndrome in these patients.. Multicenter, cross-sectional study, in patients with HT, DM2 and/or HC, consecutively recruited by primary care physicians in Spain. The blood pressure, cholesterol, basal glycaemia, obesity, smoking and physical activity were assessed. The degree of control of these CVRF and the prevalence of MS were estimated.. 2,649 patients were recruited, aged 64 (11.3) years, with a 51.6% of women. The most frequent diagnosis was HT (78.9%), followed by HC (58.4%) and DM2 (37.4%). In the whole sample, the percentages of patients who had a control or had initially normal values of blood pressure, cholesterol and basal glycemia were 40.0% (confidence interval [CI], 95% 38.2-41.9), 42.6% (95% CI, 40.5-44.7) and 62.7% (95% CI, 60.8-64.5), respectively. 15.6% of cases (95% CI, 14.3-17.0) had body mass index < or = 25 kg/m2; 87.5% were non-current smokers (95% CI, 86.2-88.8); and 46.2% practiced regular physical activity (95% CI, 44.3-48.1). 40% of patients had < or = 2 CVRF in good control. The prevalence of metabolic syndrome was 50.6% (95% CI, 48.7-52.5).. The control of the CVRF considered in primary care attended population is insufficient. Hardly one of each 2 patients with HT, DM2 and HC is under control. The overweight and sedentarism control is still poorer.

The benefit of cholesterol-lowering medications after coronary revascularization: a population study.
In clinical trials, cholesterol-lowering medications have been proven to decrease mortality and morbidity and are strongly recommended as secondary prevention in patients with established coronary artery disease. In routine practice, the translation of these benefits to elderly patients with recent coronary revascularization is less well known.. Using the provincial computerized administrative databases of the Régie de l'Assurance Maladie du Québec, we identified all elderly patients (>65 years old) in Quebec, Canada, discharged alive after a coronary revascularization procedure (percutaneous coronary intervention or coronary artery bypass graft) between April 1, 1995, and December 31, 1997, and determined the percentage fulfilling prescriptions for cholesterol-lowering drug therapy. Time-dependent multivariable models examined the clinical end points of total mortality, acute myocardial infarctions, and repeat coronary revascularizations as a function of cholesterol-lowering drug exposure. Patients were followed up until death or December 31, 1999.. We identified 11958 elderly patients who had a coronary revascularization between April 1, 1995, and December 31, 1997. During an average 3-year follow-up, users of cholesterol-lowering medications had a decreased risk of death [hazard ratio (HR) 0.66, 95% CI 0.45-0.96] or myocardial infarction (HR 0.77, 95% CI 0.54-1.11) but no reduction in repeat revascularizations (HR 1.06, 95% CI 0.88-1.28).. In this population-based study of recently revascularized elderly patients, we observed health benefits associated with the use of cholesterol-lowering medications of similar size to those seen in randomized clinical trials. The translation of these benefits from clinical trials to a nonselected population of revascularized patients emphasizes the importance of this aspect of secondary prevention in clinical practice.

Does cardiovascular therapy affect the onset and recurrence of preretinal and vitreous haemorrhage in diabetic eye disease?
To review the role of cardiovascular disease and therapy in the onset and recurrence of preretinal/vitreous haemorrhage in diabetic patients.. Retrospective case note analysis of diabetic patients with vitreous haemorrhage from the Diabetic Eye Clinic at Birmingham Heartlands Hospital.. In total, 54 patients (mean age 57.1, 37 males, 20 type I vs 34 type II diabetic patients) were included. The mean (SD) duration of diagnosed diabetes at first vitreous haemorrhage was significantly longer, 21.9 (7.6) years for type I and 14.8 (9.3) years for type II diabetic patients (P < 0.01, unpaired t-test, two-tailed).Aspirin administration was not associated with a significantly later onset of vitreous haemorrhage. Four episodes were associated with ACE-inhibitor cough. There was a trend towards HMGCoA reductase inhibitor (statin) use being associated with a delayed onset of vitreous haemorrhage: 21.4 years until vitreous haemorrhage (treatment group) vs 16.2 years (nontreatment group) (P = 0.09, two-tailed, unpaired t-test, not statistically significant). During follow-up 56 recurrences occurred, making a total of 110 episodes of vitreous haemorrhage in 79 eyes of 54 patients. The mean (range) follow-up post haemorrhage was 1067 (77-3842) days, with an average of 1.02 recurrences. Age, gender, diabetes type (I or II) or control, presence of hypertension or hypercholesterolaemia, and macrovascular complications were not associated with a significant effect on the 1-year recurrence rate. Aspirin (and other antiplatelet or anticoagulant agents) and ACE- inhibitors appeared to neither increase nor decrease the 1-year recurrence rate. However, statin use was significantly associated with a reduction in recurrence (Fisher exact P < 0.05; two-tailed) with an odds ratio (95% CI) of 0.25 (0.1-0.95).. In this retrospective analysis, the onset of preretinal/vitreous haemorrhage was not found to be accelerated by gender, hypertension, hypercholesterolaemia, evidence of macrovascular disease, or HbA1c. Neither aspirin nor ACE-inhibitor administration accelerated the onset or recurrence of first vitreous haemorrhage. Statins may have a protective role, both delaying and reducing the recurrence of haemorrhage.

[The global risk for cardiovascular disease. Who is a candidate for pharmacological prevention?].
Despite the epidemiological importance of coronary artery disease, cardiovascular events are rare from the individual viewpoint. There is considerable uncertainty when to start medical treatment. A given risk factor modification results in a relative risk reduction independent of the global risk. Therefore the global risk determines the absolute benefit of a preventive measure. The global risk can be estimated using different scoring systems. Using the global risk and the expected relative risk reduction, the Number Needed to Treat (NNT) to avoid one event or cardiac death can be calculated. The NNT is a measure for the usefulness of a preventive intervention. A NNT of < 200 appears acceptable for primary prevention. This can be achieved with pharmacological preventive strategies if the global risk of 10 years is > or = 20%. As age is one of the most important risk predictors the need for treatment at comparable risk factor constellations is age dependent. Risk stratification with estimation of the NNT is therefore important for the decision to treat or not to treat.

Explaining the increase in coronary heart disease mortality in Beijing between 1984 and 1999.
Coronary heart disease (CHD) mortality is rising in many developing countries. We examined how much of the increase in CHD mortality in Beijing, China, between 1984 and 1999 could be attributed to changes in major cardiovascular risk factors and assessed the impact of medical and surgical treatments.. A validated, cell-based mortality model synthesized data on (1) patient numbers, (2) uptake of specific medical and surgical treatments, (3) treatment effectiveness, and (4) population trends in major cardiovascular risk factors (smoking, total cholesterol, blood pressure, obesity, and diabetes). Main data sources were the WHO MONICA and Sino-MONICA studies, the Chinese Multi-provincial Cohort Study, routine hospital statistics, and published meta-analyses. Age-adjusted CHD mortality rates increased by approximately 50% in men and 27% in women (1608 more deaths in 1999 than expected by application of 1984 rates). Most of this increase ( approximately 77%, or 1397 additional deaths) was attributable to substantial rises in total cholesterol levels (more than 1 mmol/L), plus increases in diabetes and obesity. Blood pressure decreased slightly, whereas smoking prevalence increased in men but decreased substantially in women. In 1999, medical and surgical treatments in patients together prevented or postponed approximately 642 deaths, mainly from initial treatments for acute myocardial infarction ( approximately 41%), hypertension (24%), angina (15%), secondary prevention (11%), and heart failure (10%). Multiway sensitivity analyses did not greatly influence the results.. Much of the dramatic CHD mortality increases in Beijing can be explained by rises in total cholesterol, reflecting an increasingly "Western" diet. Without cardiological treatments, increases would have been even greater.

Comparison of cardiovascular risk factors and drug use in 14,544 French patients with a history of myocardial infarction, ischaemic stroke and/or peripheral arterial disease.
Atherothrombosis is a systemic disease affecting coronary, cerebral, and lower limb arteries, and requiring secondary prevention measures.. Data from three observational studies carried out in 1999-2000 (ECLAT1, APRES, PRISMA) were pooled to describe the prevalence of cardiovascular risk factors and the patterns of drug use in atherothrombotic patients.. General practitioners and cardiologists engaged in a private practice and evenly distributed in France recruited consecutive patients who had a history of at least one atherothrombotic event: myocardial infarction (MI), ischaemic stroke, and/or peripheral arterial disease (PAD).. The sample was composed of 14 544 patients (men: 75.0%, age 75 or older: 31.0%). At least one of the four major risk factors (smoking, hypertension, hypercholesterolaemia, diabetes) was present in 94.3% of the sample. Prevalence of drug use was: 78.8% (antiplatelet agents), 48.5% (statins), 36.7% (beta-blockers), and 33.4% [angiotensin-converting enzyme (ACE) inhibitors]. After adjustment for confounders, statins were taken in a significantly larger extent in patients with a history of isolated MI than in those with a previous ischaemic stroke or PAD, or in patients who suffered from both MI and ischaemic stroke. Isolated MI (as compared with ischaemic stroke and PAD) was significantly and independently associated with a higher probability to take antiplatelet agents, beta-blockers or ACE inhibitors.. At least one conventional risk factor was observed in almost all atherothrombotic patients. Use of preventive drugs was lower in patients with a history of ischaemic stroke or PAD, and should increase, accordingly to the results of recent randomized controlled trials.

[Secondary prevention of coronary disease--at the turn of the millennium in light of the Hungarian data of the EUROASPIRE I-II. Studies].
Relevant national societies attribute special importance to the secondary prevention of coronary patients. This is well formulated in their recommendations (9, 11). Actual clinical practice was studied in 1995-1996 by the EUROASPIRE I study. Its Hungarian data were published in 1999 (8). The scope of EUROASPIRE II in 1999-2000 was to study changes occurred in these 5 years. In this paper the authors intend to answer the question whether the clinical practice of secondary prevention of coronary patients showed any changes at the turn of the millennium. Participating centres, the criteria of patient selection and the applied methods were identical in the two studies. Hospital data of 516 patients below the age of 70 were analysed. There was no difference between the two studies neither in the distribution according to gender and age, nor in the number of death. Documentation of the relevant data in the hospital records improved substantially: blood pressure was registered in every patient chart, lipid values in 91%. Information on smoking however is still missing in 1/3 of the patients, while on weight and height in half of them. The response rate at the follow up investigation on was 75%. The prevalence of obesity increased by 60%, that of smoking by 13% since the first investigation 5 years ago. This rate of increase is the largest among the 9 participating centres. The prevalence of hypertension decreased by 24.5% and the proportion of hypertensive patients receiving treatment increased by 7%. In spite of these blood pressure values over 140/90 mmHg were found in 37% of the patients. The mean triglyceride value increased by 53% and the prevalence of severe hypercholesterolaemia by 43%. Lipid lowering drugs are given to 51% of the patients in contrast to 22% 5 years earlier. In spite of this cholesterol values above 5.5 mmol/l were found in 42%. In respect of prophylactic drugs the proportion of patients receiving beta blockers increased from 58 to 84%.. The evaluation of complex risk of patients and their long-term care is still deficient. Drug treatment improved quantitatively but not qualitatively. This and the lack of lifestyle-improving medical efforts is reflected by the increase of the proportion of obese and smoking patients and the persistently high prevalence of hypercholesterolaemia and hypertension.

The Avoid Stroke as Soon as Possible (ASAP) general practice stroke audit.
To determine the prevalence of stroke risk factors in a general practice population and to identify pharmacotherapies currently used in management of stroke risk factors.. Multicentre, observational study by 321 randomly selected general practitioners who each collected data on 50 consecutive patients attending their surgery.. 16 148 patients aged 30 years or older attending general practices across Australia during 2000.. Prevalence of hypertension, current smoking, diabetes, hypercholesterolaemia, atrial fibrillation, recent history of stroke or TIA; extent of pharmacotherapy use in risk-factor management.. 70% of patients had one or more risk factors and 34% had two or more. Hypertension was the risk factor with greatest prevalence (44%), followed by hypercholesterolaemia (43%) and current smoking (17%). The prevalence of risk factors generally increased with age, except for current smoking, where a decrease with age was seen. The most common pharmacotherapies were cardiovascular agents, followed by antiplatelet agents. Two-thirds of patients with hypertension were taking cardiovascular drugs, most commonly angiotensin-converting enzyme inhibitors.. Stroke risk factors are highly prevalent in general practice patients and GPs are ideally placed for opportunistic case-finding. There is considerable scope for improving management of stroke risk factors. The Avoid Stroke as Soon as Possible (ASAP) general practice stroke audit provides a baseline against which progress in risk-factor management can be measured.

Optimizing drug therapy in patients with cardiovascular disease: the impact of pharmacist-managed pharmacotherapy clinics in a primary care setting.
We evaluated the effectiveness of pharmacist-managed pharmacotherapy clinics in implementing and maximizing therapy with agents known to reduce the morbidity and mortality associated with cardiovascular disease. This was a retrospective chart review of 150 patients who were treated for coronary artery disease in primary care clinics. Appropriate treatment of hypercholesterolemia occurred in 96% of patients referred to a clinical pharmacy specialist, compared with 68% of those followed by primary care providers alone (p<0.0001). Eighty-five percent and 50%, respectively, achieved goal low-density lipoprotein (LDL) values below 105 mg/dl (p<0.0001). Appropriate therapy with aspirin or other antiplatelet or anticoagulant drugs was prescribed in 97% and 92%, respectively (p=0.146). As appropriate therapy with these agents was high in both groups, the ability to detect a difference between groups was limited. Among patients with an ejection fraction below 40%, appropriate therapy with an angiotensin-converting enzyme inhibitor or acceptable alternative was 89% and 69%, respectively (p<0.05). Twenty-seven cardiac events were documented in the clinical pharmacy group, versus 22 in the primary care group (p=0.475). Despite the relatively high percentage of patients reaching goal LDL in the primary care group, referral to clinical pharmacy specialists resulted in statistically significant increases in the number of patients appropriately treated for hypercholesterolemia and achieving goal LDL.

Co-morbidity of 'clinical trial' versus 'real-world' patients using cardiovascular drugs.
To examine discrepancies between co-morbidity of patients included in pre-marketing clinical trials of cardiovascular drugs and patients from daily practice, representing the actual users after marketing, and to investigate the availability of data regarding co-morbidity in registration files.. Data were collected from phase III trials of registration files of 16 drugs, registered in the Netherlands in the period 1985 through 1994 for the indications hypertension, angina pectoris or hypercholesterolemia, and from a general practitioners database. Patients were selected who used drugs from the same therapeutic classes for the same indication as the patients in the pre-marketing trials. Prevalences of concomitant cardiovascular, endocrine and metabolic diseases were compared between pre- and postmarketing populations. Discrepancies were defined as more than 10% difference in prevalences.. Data regarding co-morbidity were present in 13 out of 16 registration files and differed in format of reporting. For all indications, coexisting cardiovascular, endocrine and metabolic diseases were less prevalent in the pre-marketing populations, except ischemic heart disease, which was more prevalent coexisting with angina pectoris and hypercholesterolemia. Discrepancies were found for hypertensive disease, heart failure, diabetes mellitus and myocardial infarction.. Phase III trials testing cardiovascular drugs included patients with concomitant cardiovascular, endocrine and metabolic diseases, but discrepancies were present with patients in daily practice. Development of guidelines for uniform collection and reporting of co-morbidity data in pre-marketing trials is recommended, as well as further utilization of data.

Changes of ischemic heart disease in Utsunomiya, Japan, over 10 years: a survey of primary care physicians.
A total of 502 patients presenting in Utsunomiya city and its suburbs during a 10-year period were studied to determine the clinical features of ischemic heart disease and to identify coronary risk factors. The male/female ratio was 1.21, but the ratio decreased with increasing age. The duration of chest pain showed a continuous spectrum between angina and infarction, with a short duration of chest pain not being useful for excluding the diagnosis of myocardial infarction. Hypertension was more common than hypercholesterolemia in this study, although the prevalence of the latter increased slightly with time, along with the shift towards a modernized occupational pattern. Smoking was a more important risk factor for ischemic heart disease in younger individuals than in the elderly, and diabetes mellitus was highly associated with the development of myocardial infarction. The incidence of radiologically diagnosed cardiac hypertrophy and aortic calcification decreased over time. These changes may have resulted in part from improved blood pressure control and the development of new anti-hypertensive and cholesterol-lowering agents.

Hyperlipidaemia in renal transplant patients.
The aim of study was to assess the prevalence and severity of hyperlipidaemia in renal transplant patients in a Nordic country.. Multicentre, cross-sectional study.. Outpatients and ward inpatients registered from 23 hospitals covering all regions of the country.. Renal transplant patients with a functioning graft were registered: 406 patients in all; that is, 43% of the national renal transplant population. All patients used prednisolone, 71% used cyclosporine, either with (51%) or without (20%) azathioprine. Total cholesterol values from general population were obtained from a national survey.. Blood lipids and their relation to clinical parameters.. Total cholesterol was significantly higher in transplant patients than in the general population for both genders and all age groups (P < 0.01). Female patients had higher total cholesterol (mean +/- SD: 7.49 +/- 1.61 mmol L(-1)) than males (7.01 +/- 1.55 mmol L(-1); P < 0.001), and also higher HDL cholesterol (1.55 +/- 0.43 vs. males: 1.32 +/- 0.46 mmol L(-1); P < 0.001). Triglycerides were equally elevated in both genders, and 33% had values above 2.2 mmol L(-1). Reduced creatinine clearance, a high body-mass index, female gender, hypertension, and coronary artery disease were independently associated with higher total cholesterol. Beta blockers were associated with lower HDL cholesterol and higher triglycerides, and diuretics with higher triglycerides. Blood lipid levels were not associated with cyclosporine immunosuppression.. Hyperlipidaemia is prevalent after renal transplantation, and is associated with impaired graft function, hypertension, and with the use of beta blockers and diuretics, but not with the use of cyclosporine.

[Therapeutic considerations in vascular diseases of the inner ear].
I propose an analogy between vascular diseases of the inner ear and those of other organs like brain, heart or peripheral vessel diseases in which functional and organic alteration can be objectively demonstrated. Symptomatic disturbances of inner ear circulation are monoform in its clinical appearance and the term of 'otangina' is proposed for the functional result. Three types of vascular distribution are discussed for the different regulatory entities, (I) the proximal cerebral vascular type, (II) the predistal innervated regulatory type and the (III) capillary regulatory type. The formal etiology of inner ear vascular diseases is is developed on the base of organic vascular lesions, i.e. arteriosclerosis, functional alterations, i.e. vasospastic disease, and finally change in the microcirculation by alterations of the rheology of the blood. Hypertension is portrayed as a main example for cardiovascular risk factors with respect to inner ear circulatory damage but diabetes mellitus, cigarette smoking and other metabolic diseases leading to vascular disturbances have to be considered. From these considerations I have developed a basic program for the diagnosis of vascular metabolic risk factors which should be realized before any treatment is advocated. I have critically evaluated the benefit and possible hazardous effects of so called 'vasoactive' and 'cephalotropic' drugs. For most inner ear circulatory disease such therapy is contraindicated. The models of drug treatment of acute deafness and the chronic or persistent inner ear deafness should be evaluated in prospective studies.
