cardiovascular-agents and Erectile-Dysfunction

Sexual health has a fundamental role in overall health and well-being, and a healthy and dynamic sex life can make an important contribution to a good quality of life. Sexual dysfunction, and especially erectile dysfunction (ED) in men, is highly prevalent in patients with cardiovascular disease (CVD). CVD and ED have shared risk factors and pathophysiological links, such as endothelial dysfunction, inflammation and low plasma testosterone levels. ED has been shown to be an independent and early harbinger of future CVD events, providing an important window to initiate preventive measures. Therefore, screening and diagnosing ED is essential for the primary and secondary prevention of CVD because the assessment of ED offers an easy and low-cost prognostic tool that is an alternative to other investigational cardiovascular biomarkers. Moreover, ED is a major contributing factor to the discontinuation of, or poor adherence to, cardiovascular therapy. Cardiovascular drugs have divergent effects on erectile function, with diuretics and β-blockers having the worst profiles, and renin-angiotensin-aldosterone system inhibitors and nebivolol having the best profiles. Pharmacological treatment of ED has an equivocal effect on the risk of CVD, suggesting a complex interaction between ED and drugs for CVD. In this Review, we discuss how sexual function could be incorporated into the patient history taken by physicians treating individuals with CVD, not merely as part of the diagnostic work-up but as a means to pursue tangible and essential benefits in quality of life and cardiovascular outcomes.

Patients with cardiovascular disease (CVD) frequently have erectile dysfunction (ED) because the two conditions have similar risk factors and potential mechanisms. The therapeutic effect of CVD is strongly dependent upon long-term management of the condition. Patients with CVD tend to have poor medication compliance, and the coexistence of ED often discourages patients with CVD from continuing their long-term CVD management, thus worsening CVD treatment compliance. The two major reasons for poor compliance are that (i) the adverse effects of cardiovascular medications on erectile function drive people to reduce the prescribed dosage or even stop taking the medications to obtain satisfactory sexual arousal and (ii) a worsening mental state due to ED reduces medication compliance. The regular administration of phosphodiesterase-5 inhibitors (PDE5is) guarantees that the prescribed medication dosages are easy to comply with and that they improve the mental status of patients by enhancing their erectile function, resulting in improved long-term management of CVD through medication compliance. PDE5is themselves also play a role in reducing cardiovascular events and improving the prognosis. We recommend prescribing PDE5is for ED and suggest that PDE5i administration is a promising strategy to improve the long-term management of patients with both ED and CVD.

Sexual dysfunction affects millions of people with an increasing prevalence, worldwide. The pathophysiology of the disease shares several similarities with cardiovascular disease (CVD), including atherosclerosis, endothelial dysfunction, structural vascular damage and subclinical inflammation. Erectile dysfunction (ED) and female sexual dysfunction are common among patients with CVD and risk factors such as hypertension, diabetes, obesity and metabolic syndrome. Given the common pathogenesis of the diseases, ED is an independent prognostic factor of future ED events. Patients with overt ED or risk factors are usually treated with several drugs for the management of these conditions. Several of these drugs have been evaluated for their effect on sexual activity.. Among the antihypertensive drugs, diuretics and beta-blockers seem to exert a detrimental impact on sexual function, with nebivolol being the only beta-blocker with favorable properties through an increase in nitric oxide bioavailability. In contrast, renin-angiotensin system inhibitors and calcium-channel blockers have a neutral effect on sexual activity. Hypoglycemic drugs have been less evaluated in the ED setting, with metformin, pioglitazone and liraglutide presenting favorable results. Statins on the other hand have not provided consistent results with observational studies suggesting a detrimental role in sexual activity and a few randomized studies indicating a neutral or even beneficial effect on erectile function.

Erectile dysfunction is common in the patient with cardiovascular disease. It is an important component of the quality of life and it also confers an independent risk for future cardiovascular events. The usual 3-year time period between the onset of erectile dysfunction symptoms and a cardiovascular event offers an opportunity for risk mitigation. Thus, sexual function should be incorporated into cardiovascular disease risk assessment for all men. A comprehensive approach to cardiovascular risk reduction (comprising of both lifestyle changes and pharmacological treatment) improves overall vascular health, including sexual function. Proper sexual counselling improves the quality of life and increases adherence to medication. This review explores the critical connection between erectile dysfunction and cardiovascular disease and evaluates how this relationship may influence clinical practice. Algorithms for the management of patient with erectile dysfunction according to the risk for sexual activity and future cardiovascular events are proposed.

Heart failure (HF) is a complex clinical syndrome with a constantly increasing incidence and prevalence in western countries. Total absence of sexual activity is registered in 30% of HF patients. Moreover, HF-induced reduction in exercise tolerance, side effects of HF medications and the coexistence of shared risk factors between HF and sexual dysfunction may further aggravate the sexual health of HF patients. The purpose of this review is to examine the pathophysiological mechanisms behind the association of erectile dysfunction (ED) and HF, the potential therapeutic approaches and the eventual indications for sexual activity in HF patients. Medline and Cochrane Library search was performed from January 1970 through October 2012 to retrieve relevant papers outlining the association between ED and HF. Many evidences have outlined a tight association between ED and HF pathophysiological standpoint. Shared risk factors, common pathogenic traits and epidemiologic association represent some of the links between these conditions. Erectile dysfunction has been recognized as an earlier predictor of cardiovascular events; moreover, HF itself may cause and/or worsen ED because of its particular feature and co-morbidities. Furthermore, some cardiovascular drugs may contribute to impaired erectile function. In stable patients with stable HF, sexual activity is generally not contraindicated but it should be encouraged, as a form of moderate-intensity physical exertion. An effective treatment of ED in HF patients should be founded on the correction of reversible risk factors, on the choice of cardiovascular drugs with the lowest effect upon patient's erectile function, and on the use of phosphodiesterase-5-inhibitors. Physicians should be aware of the close relation between HF and ED and of the related clinical and therapeutic implications, in order to improve patients quality of life and clinical outcome.

Erectile dysfunction is a major problem with an increasing prevalence in cardiovascular high-risk patients due to its association with cardiovascular risk factors. Drugs used for evidence-based treatment of cardiovascular diseases have been reported to decrease erectile function, but possible mechanisms are poorly characterised.. MEDLINE, EMBASE and Cochrane Registry search were performed including manuscripts until January 2010. Searching terms are: 'erectile dysfunction or impotence' in combination with 'ACE-inhibitors', 'angiotensin', 'beta-blockers', 'calcium antagonist' and 'diuretics'. Animal studies, letters, reviews, case-reports and manuscripts other than English language and trials dealing with combination treatment are excluded.. Analysis of literature revealed five epidemiological trials evaluating the effect of different cardiovascular drugs on erectile function. There were eight trials evaluating the effect of beta-blockers, five trials evaluating the effect of ace-inhibitors or angiotensin-receptor-blockers and one trial evaluating the effect of diuretics on erectile function. Results of these trials demonstrate that only thiazide diuretics and beta-blockers except nebivolol may adversely influence erectile function. ACE-inhibitors, angiotensin-receptor-blockers and calcium-channel-blockers are reported to have no relevant or even a positive effect on erectile function.. Inappropriate patients' concerns about adverse effects of cardiovascular drugs on erectile function might limit the use of important medications in cardiovascular high-risk patients. Knowledge about the effects of drug-treatments on erectile function and about the major role of the endothelium in penile function might improve patients' adherence to evidence based treatment of cardiovascular diseases.

Erectile dysfunction (ED) shares similar modifiable risks factors with coronary artery disease (CAD). Lifestyle modification that targets CAD risk factors may also lead to improvement in ED. We conducted a systematic review and meta-analysis of randomized controlled trials evaluating the effect of lifestyle interventions and pharmacotherapy for cardiovascular (CV) risk factors on the severity of ED.. A comprehensive search of multiple electronic databases through August 2010 was conducted using predefined criteria. We included randomized controlled clinical trials with follow-up of at least 6 weeks of lifestyle modification intervention or pharmacotherapy for CV risk factor reduction. Studies were selected by 2 independent reviewers. The main outcome measure of the study is the weighted mean differences in the International Index of Erectile Dysfunction (IIEF-5) score with 95% confidence intervals (CIs) using a random effects model.. A total of 740 participants from 6 clinical trials in 4 countries were identified. Lifestyle modifications and pharmacotherapy for CV risk factors were associated with statistically significant improvement in sexual function (IIEF-5 score): weighted mean difference, 2.66 (95% CI, 1.86-3.47). If the trials with statin intervention (n = 143) are excluded, the remaining 4 trials of lifestyle modification interventions (n = 597) demonstrate statistically significant improvement in sexual function: weighted mean difference, 2.40 (95% CI, 1.19-3.61).. The results of our study further strengthen the evidence that lifestyle modification and pharmacotherapy for CV risk factors are effective in improving sexual function in men with ED.

Erectile dysfunction (ED) is an increasingly common problem in the aging population and has been associated with chronic heart failure (HF), either as an epiphenomenon or even as an early marker for underlying cardiovascular disease. ED has a significant effect on patients' quality of life. This chapter reviews ED in patients with HF and prevention and treatment based on current data from the literature. Causes include physiologic changes resulting in decreased cardiac function and exercise capacity, intrinsic vascular and neurohormonal abnormalities, and extrinsic factors such as medication side effects and psychological issues. Physicians should address these issues with patients and begin treatment by optimizing HF management and minimizing medications with ED side effects. Use of phosphodiesterase-5 inhibitors provides significant improvement of ED and quality of life. Further research still is needed regarding long-term effects of ED treatment, investigation of newer medications, and preventive measures in this patient population.

Erectile dysfunction (ED) is a sensitive indicator of wider arterial insufficiency and an early correlate for the presence of ischemic heart disease. Among patients with coronary artery disease, prevalence reports of ED range from 42% to 75%. The US Food and Drug Administration has approved 3 phosphodiesterase-5 (PDE-5) inhibitors for treatment of male sexual dysfunction: sildenafil, tadalafil, and vardenafil. PDE-5 inhibitors also have cardiovascular effects. They inhibit PDE-5 enzymes in pulmonary vasculature, which causes vasodilation that decreases pulmonary vascular pressure. Sildenafil is approved for treatment of patients with pulmonary hypertension. PDE-5 inhibition with sildenafil improves cardiac output by balancing pulmonary and systemic vasodilation, and augments and prolongs the hemodynamic effects of inhaled nitric oxide in patients with chronic congestive heart failure and pulmonary hypertension. In vivo and in vitro studies are examining the possible beneficial effects of PDE-5 inhibitors in conditions such as myocardial infarction and endothelial dysfunction.

The phosphodiesterase-5 inhibitors (PDE5i) sildenafil, vardenafil, and tadalafil are considered first-line therapy for the treatment of patients with erectile dysfunction (ED). In addition to the classical pro-erectile-effect, clinical findings have suggested that they can also influence vascular tone in pulmonary, coronary and other vascular tissues, as well as improving symptoms associated with benign prostatic hyperplasia. Therefore, considering the hypothetical widespread application of PDE5i, the potential for drug-drug interactions emerges as a relevant factor in determining the safety profile of PDE5i. Review of relevant literature was conducted using data sources from MEDLINE (1998, to June 2007). The use of nitrates remains the only contraindication for all 3 PDE5i. Vardenafil is also not recommended in patients taking type 1A (such as quinidine, or procainamide) or type 3 antiarrhythmics (such as sotalol, or amiodarone) while no other major limitations have been reported for tadalafil and sildenafil. In contrast to previously reported labeling, recent studies have suggested only a precaution, but not contraindication with the concomitant use of alpha-blockers agents. In addition, precaution is also suggested in the presence of potent CYP3A inhibitors, such as azole antifungals, antiretroviral protease inhibitors, or macrolid antibiotics. This is because sildenafil, vardenafil, and tadalafil are metabolized mainly via the CYP3A4 pathway. On the other hand, statins and testosterone seem to have synergic effects with PDE5i on sexual activity.

Endothelial dysfunction (EtD) has emerged as a critical master pathway in the pathogenesis of both vascular disease and erectile dysfunction (ED). Drugs that have been developed for vascular diseases and/or found to have beneficial endothelial effects may be helpful in the management of ED. In this manuscript we summarize the current state of the art with respect to endothelial active drugs and discuss the evidence supporting their use in the management of ED. Pubmed query for the terms Endothelial dysfunction, erectile dysfunction, pharmaceuticals, "endothelium", "function", "pharmaceutical", "eNOS", "erectile dysfunction" and "erectile function" was conducted. Relevant articles were reviewed and summarized. A variety of cardiovascular medications have mechanisms of action that involve the endothelium. Examples include HMG-CoA Reductase inhibitors ("statins"), Angiotensin Converting Enzyme Inhibitors (ACEI), Angiotensin Receptor blockers (ARB), Endothelin Receptor Antagonists (ERA), certain beta blockers, and some oral hypoglycemics. Some of these drugs have been found to improve penile erection, although an endothelium dependent mechanism has not been conclusively demonstrated in all studies. Drugs that improve endothelial function in the cavernous arteries and the erectile tissues of the corpora cavernosa hold great promise in treating or at least minimizing the vascular damage that contributes to ED. ACEI and ARB appear to hold great promise in this regard, while statins and oral hypoglycemics may play a potentially useful role as adjunctive therapy for ED. Improvements in endothelial function may help reverse ED in some cases, which would be a marked improvement over management with currently available "on demand" ED therapies.

Erectile dysfunction (ED) is a highly prevalent disorder associated with a significant burden of illness. The prevalence and incidence of ED are strongly age-related, affecting more than half of men >60 years. The first Princeton Consensus Conference (Princeton I) in 1999 developed guidelines for safe management of cardiac patients regarding sexual activity and the treatment of ED.. The second conference (Princeton II) was convened to update the recommendations based on the expanding knowledge base and new treatments available. This article reviews and expands on the Princeton II guidelines to address sexual dysfunction and cardiac risk.. A consensus panel of experts reviewed recent multinational studies in safety and drug interaction data for three phosphodiesterase type 5 (PDE5) inhibitors (sildenafil, tadalafil, vardenafil), with emphasis on the safety of these agents in men with ED and concomitant cardiovascular disease.. Erectile dysfunction is an early symptom or harbinger of cardiovascular disease, due to the common risk factors and pathophysiology mediated through endothelial dysfunction. Major comorbidities include diabetes, hypertension, hyperlipidemia and heart disease. Any asymptomatic man who presents with ED that does not have an obvious cause (e.g., trauma) should be screened for vascular disease and have blood glucose, lipids, and blood pressure measurements. Ideally, all patients at risk but asymptomatic for coronary disease should undergo an elective exercise electrocardiogram to facilitate risk stratification. Lifestyle intervention in ED, specifically weight loss and increased physical activity, particularly in patients with ED and concomitant cardiovascular disease, is literature-supported.. The recognition of ED as a warning sign of silent vascular disease has led to the concept that a man with ED and no cardiac symptoms is a cardiac (or vascular) patient until proven otherwise. Men with ED and other cardiovascular risk factors (e.g., obesity, sedentary lifestyle) should be counseled in lifestyle modification.

Erectile dysfunction is common and closely associated with age and risk factors for cardiovascular disease. The oral selective inhibitors of phosphodiesterase type 5 (PDE5) have become the treatments of choice, owing to their convenience, general safety, and broad-spectrum effectiveness. For the same reasons, they have greatly simplified the workup. Thus, the general practitioner has gradually replaced the urologist for the initial management of erectile dysfunction and the proper evaluation of cardiac status before starting treatment with the PDE5 inhibitors. The following review provides a practical approach for the management of erectile dysfunction in primary care.

Recent studies have highlighted the relation between erectile dysfunction (ED) and cardiovascular disease. In particular, the role of endothelial dysfunction and nitric oxide in ED and atherosclerotic disease has been elucidated. Given the large number of men receiving medical treatment for ED, concerns regarding the risk for sexual activity triggering acute cardiovascular events and potential risks of adverse or unanticipated drug interactions need to be addressed. A risk stratification algorithm was developed by the First Princeton Consensus Panel to evaluate the degree of cardiovascular risk associated with sexual activity for men with varying degrees of cardiovascular disease. Patients were assigned to 3 categories: low, intermediate (including those requiring further evaluation), and high risk. This consensus study from the Second Princeton Consensus Conference corroborates and clarifies the algorithm and emphasizes the importance of risk factor evaluation and management for all patients with ED. The panel reviewed recent safety and drug interaction data for 3 phosphodiesterase (PDE)-5 inhibitors (sildenafil, tadalafil, vardenafil), with emphasis on the safety of these agents in men with ED and concomitant cardiovascular disease. Increasing evidence supports the role of lifestyle intervention in ED, specifically weight loss and increased physical activity, particularly in patients with ED and concomitant cardiovascular disease. Special management recommendations for patients taking PDE-5 inhibitors who present at the emergency department and other emergency medical situations are described. Finally, further research on the role of PDE-5 inhibition in treating patients with other medical or cardiovascular disorders is recommended.

The increased expression and activity of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex has emerged as a major common factor in the etiology of all forms of cardiovascular diseases since the upregulation of intravascular NADPH oxidase results in the formation of superoxide (O(2)(-)), which in turn promotes vasculopathy. An ever-increasing number of drugs commonly used in cardiovascular medicine have been shown to influence NADPH oxidase expression and activity. These include nitric oxide donors, nitroaspirin, eicosanoids, phosphodiesterase inhibitors, corticosteroids, antioxidants, and specific inhibitors. The objective of this review is to discuss these drugs in relation to the mechanisms underlying their effects on NADPH oxidase activity and the expression and therapeutic implications of these effects.

Atrial fibrillation (AF) is the most common sustained rhythm disorder observed in clinical practice and predominantly associated with cardiovascular disorders such as coronary heart disease and hypertension. However, several classes of drugs may induce AF in patients without apparent heart disease or may precipitate the onset of AF in patients with preexisting heart disease. We reviewed the literature on drug-induced AF, using the PubMed/Medline and Micromedex databases and lateral references. Successively, we discuss the potential role in the onset of AF of cardiovascular drugs, respiratory system drugs, cytostatics, central nervous system drugs, genitourinary system drugs, and some miscellaneous agents. Drug-induced AF may play a role in only a minority of the patients presenting with AF. Nevertheless, it is important to recognize drugs or other agents as a potential cause, especially in the elderly, because increasing age is associated with multiple drug use and a high incidence of AF. This may contribute to timely diagnosis and management of drug-induced AF.

Modern cardiac rehabilitation is a comprehensive program of secondary prevention for patients with heart disease. Moreover, it is an important context in which to broach issues of impaired sexual function. Sexual problems plague a large portion of our cardiac patient population. Unspoken+ concerns about impotence, now more correctly called erectile dysfunction (ED), are common, as are concerns about the safety of engaging in sexual activity, especially after major cardiac events or therapeutic interventions. A large proportion of patients do not return to normal sexual activity after a cardiac event. Many factors, including normal age-related changes in sexual response, medication-induced dysfunction, and vascular changes associated with risk factors (e.g., diabetes and dyslipidemia), as well as the emotional impact of symptomatic heart disease, may influence sexual function in these patients. These factors, occurring alone or in combination, probably explain the discouraging prevalence of sexual dysfunction in patients with manifest cardiac disease. Because so few patients have specific cardiac reasons for limiting sexual activity, a clear opportunity exists for cardiologists and their staff to help enhance the emotional well-being and overall quality of life of their cardiac patients.

The understanding of pharmacology of impotence has shown a steady improvement over the last 15 years which has resulted in a better appreciation of the neurovascular mechanisms of the erectile process especially at the level of the corpora cavernosa; however, central mechanisms which control libido and erection are not yet completely elucidated. Frequent diseases most commonly encountered in elderly patients--i.e. diabetes, hypertension, atherosclerosis, depression, etc--represent a frequent cause of erectile dysfunction (ED) and are treated with medications that can interfere with sexual functioning at the central and/or peripheral level. Antidepressants, including the tricyclics and the monoamine oxidase inhibitors, have been implicated in ED, decreased libido, and impaired ejaculation. Most antihypertensives have been associated with some erectile impairment, but diuretics seem to have little effect on erectile function. The calcium channel blockers and ACE inhibitors are associated with a low incidence of ED. Sympatholytic antihypertensives seldom cause importence but can cause retrograde ejaculation because of the relaxation of the smooth muscles in the prostatic urethra and bladder neck. The most commonly prescription drugs that can affect sexual function are briefly discussed and an integrated pharmacological approach to the patient with drug-induced ED is proposed.

Sexual difficulties are highly prevalent in male patients with cardiovascular diseases, such as hypertension, atherosclerosis, and hypercholesterolemia. Recently, several studies have been conducted on the effects of cardiovascular diseases, as well as associated drug and nondrug treatments, on nocturnal penile tumescence (NPT) and other measures of sexual function. Although an overall trend has been observed toward decreased NPT in patients with chronic hypertension and other cardiovascular conditions, design and methodological difficulties have been noted in most studies, and results have been generally, inconclusive. Similarly, antihypertensive drugs such as beta-blockers and diuretics have been associated with diminished NPT in several studies, although methodological problems have again been noted. Furthermore, the mechanism of action of antihypertensive drugs on sleep-related erections has not been determined. Most recently, a positive effect of cholesterol-lowering drugs (pravastatin, lovastatin) on NPT has been observed in middle-aged males with chronic hypercholesterolemia. Additional studies of the effects of cardiovascular disease on NPT and other measures of sexual function are needed.

The presence of concomitant erectile dysfunction (ED) with heart failure (HF) is not surprising, because endothelial dysfunction is pathophysiologic signature of both ED and HF. ED significantly and adversely affects quality of life in patients with HF. It was demonstrated that ivabradine treatment can improve endothelial function and ED in experimental models. In this study, we aimed to determine the effect of ivabradine treatment on ED in patients with HF via International Index of Erectile Function (IIEF-5) questionaire.. Consequently, 29 patients, between 18 and 70 years of age, male with chronic HF known for at least 1 year, New York Heart Association functional class I-II, left ventricule ejection fraction less than 40%, in sinus rhythm with a resting HR of at least 70 beats per minute (b.p.m.), who were intended to be treated with ivabradine according to the decision of their physicians were evaluated to determine ED. We used the Turkish version of the IIEF-5 questionnaire to evaluate ED on the last 6-month period. Twenty-four of 29 patients who scored ≤21 were considered to have ED and included to the study. IIEF-5 scores for each question and domains were calculated for all responders at baseline and at 6-month follow-up visit in order to determine any effect of ivabradine treatment on ED in patients with HF.. According to the data of survey, Cronbach's alpha coeffient for all of the patients who were included into the study were 0.84 and detected highly reliable. IEFF-5 questionnaire scores increased significantly (p = .003) after the ivabradine treatment, on the contrary, significant decrease in HR was revealed as expected. HR is decreased steadily after ivabradine treatment and mean decrease in HR was 11.5 ± 9.4 in this study population. Likewise, negative correlation was demonstrated between decrease in HR (p < .001) and increase in IEFF-5 scores (p = .003).. Although lack of patients with HF have been evaluated in this study population, initial results seem promising that ivabradine has favorable effects on ED. These findings were postulated to be dependent exclusively on HR reduction. As a sequel, cardiologist should avoid neglecting ED to improve medical compliance as well as quality of life in patients with heart failure. This pilot study provide some data for further randomized controlled studies.

Erectile dysfunction (ED) is the inability or insufficiency of penile erection that causes dissatisfaction during sexual intercourse. ED is seen in patients with heart failure (HF), ranging from 56% to 81% depending on the severity. Patients usually blame their cardiovascular medications for their ED. Ivabradine is used for antianginal effects, to improve exercise intolerance, and to decrease mortality in patients with HF. Most beta-blockers are known to cause ED, but unlike beta-blockers the effect of ivabradine over ED has never been evaluated.. We investigated the effect of ivabradine on ED in patients with HF.. Thirty-one patients with HF (all men) under optimal treatment for HF (except ivabradine) were recruited. Patients were evaluated with the internationally validated Sexual Health Inventory for Men (SHIM) questionnaire before the initiation of ivabradine and at the sixth month of the treatment. SHIM scores previous to treatment and at six months were compared using Wilcoxon signed rank test. A p value < 0.05 was accepted as statistically significant.. At six months of follow-up after the initiation of ivabradine, a significant increase in patients with normal libido was found (p < 0.001).. This is a novel study that evaluates the effect of ivabradine on human with HF. Ivabradine improved libido in patients with HF.

Sexual activity is a central component of intimate relationships, but sexual function may be impaired by coronary heart disease (CHD). There have been few representative population-based comparisons of sexual behaviour and concerns in people with and without CHD. We therefore investigated these issues in a large nationally representative sample of older people.. We analysed cross-sectional data from 2979 men and 3711 women aged 50 and older from the English Longitudinal Study of Ageing. Sexual behaviour and concerns were assessed by validated self-completion questionnaire and analyses were weighted for non-response. Covariates included age, partnerships status and comorbidities.. There were 376 men and 279 women with CHD. Men with CHD were less likely to be sexually active (68.7% vs 80.0%, adjusted OR 0.62, 95% CI 0.47 to 0.81), thought less about sex (74.7% vs 81.9%, OR 0.72, CI 0.54 to 0.95), and reported more erectile difficulties (47.4% vs 38.1%, OR 1.46, CI 1.10 to 1.93) than men without CHD. Effects were more pronounced among those diagnosed within the past 4 years. Women diagnosed <4 years ago were also less likely to be sexually active (35.4% vs 55.6%, OR 0.44, CI 0.23 to 0.84). There were few differences in concerns about sexual activity. Cardiovascular medication showed weak associations with erectile dysfunction.. There is an association between CHD and sexual activity, particularly among men, but the impact of CHD is limited. More effective advice after diagnosis might reverse the reduction in sexual activity, leading to improved quality of life.

Erectile dysfunction is a common problem among patients with cardiovascular diseases and the influence of cardiovascular drugs is much debated. The aim of this study was to evaluate the short term potential for different cardiovascular drugs to affect the risk of being prescribed a drug against erectile dysfunction.. We employed a symmetry analysis design and included all Danish male individuals born before 1950 who filled their first ever prescription for a cardiovascular drug and a 5-phosphodiesterase inhibitor within a 6 month interval during 2002-2012. If the cardiovascular drug induces erectile dysfunction, this would manifest as a non-symmetrical distribution of subjects being prescribed the cardiovascular drug first vs. persons following the opposite pattern. Furthermore, we calculated the number of patients needed to treat for one additional patient to be treated for erectile dysfunction (NNTH).. We identified 20 072 males with a median age of 64 years (IQR 60-70) who initiated a cardiovascular drug and a 5-phosphodiesterase inhibitor within a 6 month interval. Sequence ratios showed minor asymmetry in prescription orders after adjustment for trends in prescribing. This asymmetry was most profound for thiazides (1.28, 95% CI 1.20, 1.38), calcium channel blockers (1.29, 95% CI 1.21, 1.38) and ACE inhibitors (1.29, 95% CI 1.21, 1.37), suggesting a small liability of these drugs to provoke erectile dysfunction. NNTH values were generally large, in the range of 330-6400, corresponding to small absolute effects.. Our study does not suggest that cardiovascular drugs strongly affect the risk of being prescribed a drug against erectile dysfunction on a short term basis.

During the past 18 years, sildenafil has evolved from a potential anti-angina drug to an on-demand treatment for erectile dysfunction and more recently to a new orally active treatment for pulmonary hypertension. Recent studies suggest that the drug has powerful cardioprotective effect against ischemia/reperfusion injury, doxorubicin-induced cardiomyopathy and anti-hypertensive effect induced by chronic inhibition of nitric oxide synthase in animals. Based on several recent basic and clinical studies, it is clear that sildenafil and other clinically approved type-5 phosphodiesterase-5 inhibitors including vardenafil and tadalafil will eventually be developed for several cardiovascular indications including essential hypertension, endothelial dysfunction, ischemia/reperfusion injury, myocardial infarction, ventricular remodeling and heart failure.

Multiple regulatory systems are involved in normal erectile function. Disruption of psychological, neurological, hormonal, vascular, and cavernosal factors, individually, or in combination, can induced erectile dysfunction (ED). The contribution of neurogenic, vascular, and cavernosal factors was thoroughly reviewed by our committee, while psychological and hormonal factors contributing to ED were evaluated by other committees.. To provide state of the art knowledge on the physiology of ED.. An international consultation in collaboration with the major urology and sexual medicine associations assembled over 200 multidisciplinary experts from 60 countries into 17 committees. Committee members established specific objectives and scopes for various male and female sexual medicine topics. The recommendations concerning state-of-the-art knowledge in the respective sexual medicine topic represent the opinion of experts from five different continents developed in a process over a 2-year period. Concerning the pathophysiology of ED committee, there were seven experts from five different countries.. Expert opinion was based on the grading of evidence-based medical literature, widespread internal committee discussion, public presentation, and debate.. The epidemiology and classification of neurogenic ED was reviewed. The evidence for the association between vascular ED and atherosclerosis/hypercholesterolemia, hypertension and diabetes was evaluated. In addition, the pathophysiological mechanisms implicated in vascular ED were defined, including: arterial remodeling, increased vasoconstriction, impaired neurogenic vasodilatation, and impaired endothelium-dependent vasodilatation. The possible mechanisms underlying the association between chronic renal failure and ED were also evaluated as well as the evidence supporting the association of ED with various classes of medications.. A better understanding of how diseases interfere with the physiological mechanisms that regulate penile erection has been achieved over the last few years, which helps establish a strategy for the prevention and treatment of ED.

After the acute phase, a patient who is diagnosed with cardiac or vascular disease becomes "chronically ill". This patient will then still spend many years without symptoms or impairments. One day, a percentage of such patients will be confronted with the problem of erectile dysfunction. Various studies have demonstrated that this problem occurs with a higher frequency in patients with cardiovascular diseases, in particular when they have to be treated for hypertension, diabetes mellitus or dyslipidemia. Very rarely are stenoses or occlusions found in the arteries responsible for penile circulation. More recent data indicates that a diffuse anomaly of the vascular endothelium is present, for which erectile dysfunction is a marker. Nowadays, medical care has achieved a better degree of standardization, not only thanks to knowledge about the effects of cardiovascular medication, but also because the physician can now prescribe drugs that treat erectile dysfunction.

To identify a Dutch cohort of sildenafil users and describe their baseline characteristics.. Each pharmacy in The Netherlands (n = 1571) was asked to identify prospectively the first 20 sildenafil prescriptions in their pharmacy over 1 year, and to complete and return a registration form. The collected data included patient characteristics, the details of the sildenafil prescription (date, prescriber, number of prescriptions, dosing), and the use of co-medication by the patient in the year preceding the sildenafil prescription.. Data were collected from 4460 sildenafil prescriptions during the year under study, relating to 3477 individual patients. Most of the cohort had cardiovascular morbidity or diabetes. Sildenafil seems to have been used by a new, previously untreated population of patients with erectile dysfunction. In addition, 69 men were identified who could have been using nitrates and sildenafil concomitantly.. A cohort of patients using sildenafil was identified and characterized; they appeared to be representative of sildenafil users in The Netherlands. This cohort will be followed prospectively to evaluate the medical status (particularly cardiovascular) of the patients with time.

To examine the association of commonly used drugs with erectile dysfunction (ED) at two time points.. Population-based, cross-sectional, survey analysis.. Randomly selected cohort of men in the Massachusetts Male Aging Study (MMAS) that included 1476 men for the baseline (1987-1989) and 922 for the follow-up (1995-1997) analyses.. Crude associations between specific drug categories were examined with chi2 statistics. Logistic regression analysis was used to separate the effect of drugs from the influence of heart disease, hypertension, untreated diabetes, or depressive symptoms.. In the MMAS, medical history, current drug use, and erectile function status were ascertained with in-home interviews. In unadjusted analyses, thiazide and nonthiazide diuretics, beta-blockers, calcium channel blockers, angiotensin-converting enzyme inhibitors, benzodiazepines, digitalis, nitrates, 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, and histamine2 receptor antagonists were associated with prevalent ED. Adjustment for comorbidities and health behaviors attenuated these associations, with only nonthiazide diuretics and benzodiazepines remaining statistically significant.. Several common drugs may increase prevalence of ED; however, additional data from larger populations are needed to determine whether these associations are independent of underlying health conditions and to explore the effects of dosage and duration of use.

To evaluate which vasoactive agents have synergistic effects on the cavernosal smooth muscles of rabbits and rats when the agents are combined with sildenafil.. Relaxation responses of cavernosal smooth muscle to single agents (phentolamine, moxisylyte, sodium nitroprusside, forskolin, vasoactive intestinal peptide, VIP, papaverine and sildenafil) in the rabbit, and prostaglandin-E1 and sildenafil in the rat, and to combinations of each agent plus sildenafil, were assessed in vitro. The response to sildenafil of the rabbit strips with and without incubation with l-arginine (1 mmol/L) for 20 min was also evaluated. The effective concentrations for a half-maximal response of single agents and combination solutions were compared.. All single agents induced concentration-dependent relaxation of the rabbit and rat cavernosal smooth muscles. There was significant synergism on rabbit cavernosal smooth muscle when the sildenafil was combined with forskolin, sodium nitroprusside, VIP or phentolamine. There was also significant synergism with sildenafil plus prostaglandin-E1 in rat cavernosal muscles. There were no synergistic effects of combinations of sildenafil plus moxisylyte, papaverine or l-arginine.. These results suggest potentially effective combined therapies of sildenafil and intraurethral or intracavernosal prostaglandin-E1, intracavernosal forskolin or VIP, or oral phentolamine for patients with erectile dysfunction who have no success after monotherapy with these agents.
