[Heart failure in diabetes].
    Wiener medizinische Wochenschrift (1946), 2009, Volume: 159, Issue:5-6

    Interactions of glucose metabolism and chronic heart failure have been confirmed by many epidemiologic studies. The association of HbA1c with an increasing risk of heart failure clearly underlines the connection between both diseases. Coronary artery disease (CAD), hypertension and diabetic cardiomyopathy are long-term complications of diabetes mellitus, resulting in diabetic heart failure. Dysfunction of many regulation systems leads to specific diabetic cardiomyopathy, which has been firstly described by Rubler. A reduction in the cardiac expression of the Na-Ca exchanger pump and SERCA2a protein results in an imbalance in cardiac calcium handling. The overactive renin angiotensin aldosteron system (RAAS) also contributes to the impairment of myocardial function. Hyperlipidaemia, hpyerinsulinaemia and hyperglycaemia directly trigger diabetic cardiomyopathy. Generally chronic heart failure is a clinical diagnosis verified by blood tests like NT-proBNP and cardiac ultrasound. Recommendations on treatment of diabetic heart failure are based on subgroup analysis of the large heart failure trials.

Prevalence of pulmonary hypertension in myelofibrosis.
    Annals of hematology, 2020, Volume: 99, Issue:4

    Pulmonary hypertension (PH) has been described in myelofibrosis (MF), but it is rare and typically found in advanced disease. Although the etiology of PH in MF is unclear, early predictors may be detected by echocardiogram. The goals of our study were to evaluate the prevalence of PH as determined by echocardiography in a cohort of MF patients and to identify clinical risk factors for PH. We performed a retrospective review of MF patients from October 2015 to May 2017 at MD Anderson Cancer Center in the ambulatory clinic, and those with echocardiogram were included. Clinical, echocardiographic, and laboratory data were reviewed. Patients with and without PH were compared using a chi-square or Fisher's exact test, and logistic regression was performed with an outcome variable of PH. There were 143 patients with MF who underwent echocardiogram, and 20 (14%) had echocardiographic findings consistent with PH. Older age, male gender, hypertension, hyperlipidemia, coronary artery disease, dyspnea, hematocrit, brain natriuretic peptide (BNP), and N-terminal prohormone BNP (NT-proBNP) were significantly different between those without PH and those with PH (p < 0.05). Female gender was protective (OR 0.21, 95% CI 0.049-0.90, p = 0.035), and NT-proBNP was a significant clinical predictor of PH (OR 1.07, CI 1.02 = 1.12, p = 0.006). PH in MF is lower than previously reported in our MF cohort, but many patients had cardiac comorbidities. PH due to left-sided heart disease may be underestimated in MF. Evaluation of respiratory symptoms and elevated NT-proBNP should prompt a baseline echocardiogram. Early detection of PH with a multidisciplinary approach may allow treatment of reversible etiologies.

Atrial Cardiopathy and Cryptogenic Stroke: A Cross-sectional Pilot Study.
    Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association, 2016, Volume: 25, Issue:1

    There is increasing evidence that left atrial dysfunction or cardiopathy is associated with ischemic stroke risk independently of atrial fibrillation. We aimed to determine the prevalence of atrial cardiopathy biomarkers in patients with cryptogenic stroke.. We included consecutive patients with ischemic stroke enrolled in the New York Columbia Collaborative Specialized Program of Translational Research in Acute Stroke registry between December 1, 2008, and April 30, 2012. Medical records were reviewed and patients with a diagnosis of cryptogenic stroke were identified. Atrial cardiopathy was defined as at least one of the following: serum N-terminal probrain natriuretic peptide (NT-proBNP) level greater than 250 pg/mL, P-wave terminal force velocity in lead V1 (PTFV1) on electrocardiogram (ECG) greater than 5000 µV⋅ms, or severe left atrial enlargement (LAE) on echocardiogram. We compared clinical, echocardiographic, and radiological characteristics between patients with and without atrial cardiopathy.. Among 40 patients with cryptogenic stroke, 63% had at least one of the biomarkers of atrial cardiopathy; 49% had elevated NT-proBNP levels, 20% had evidence of increased PTFV1 on ECG, and 5% had severe LAE. Patients with atrial cardiopathy were more likely to be older (76 versus 62 years, P = .012); have hypertension (96% versus 33%, P < .001), hyperlipidemia (60% versus 27%, P = .05), or coronary heart disease (28% versus 0%, P = .033); and less likely to have a patent foramen ovale (4% versus 40%, P = .007).. There is a high prevalence of biomarkers indicative of atrial cardiopathy in patients with cryptogenic stroke. Clinical trials are needed to determine whether these patients may benefit from anticoagulation to prevent stroke.

Increased serum level of N-terminal Pro-B-type natriuretic peptide as a possible biomarker of cardiovascular risk in psoriatic patients.
    Journal of the European Academy of Dermatology and Venereology : JEADV, 2015, Volume: 29, Issue:5

    Apparently, these days psoriasis is regarded as a systemic disease with frequent cardiovascular comorbidities, such as hypertension, myocardial infarction, valvular defects etc., which may lead to reduced lifespan or even sudden death. Therefore, it is important that biomarkers helpful in early detection or prediction of cardiovascular complications as well as their prevention should be identified. Even though the N-terminal pro B-type natriuretic peptide (NT-proBNP) is a well-known cardiovascular predictor in cardiovascular (CV) patients and in the general population, its usefulness in detection of CV comorbidities in psoriatic patients is still unclear.. The aim of the study was to determine whether the N-terminal pro B-type natriuretic peptide (NT-proBNP) concentration was increased in psoriatic patients.. The study included 73 psoriatic patients and 45 age-matched healthy individuals. The serum NT pro-BNP concentration as well as lipid profile parameters were assessed in the study and control groups. Correlations between patients' clinical data, their serum NT-proBNP and lipid concentrations were calculated.. The serum concentration of NT-proBNP was significantly higher in psoriatic patients (109.22 ± 172.59 pg/mL) in comparison with controls (35.82 ± 22.90 pg/mL) (P = 0.000054). In 28 (38.36%) psoriatic patients the lipid profile was within normal limits, whereas in 45 (61.64%) psoriatic patients triglyceride and/or total cholesterol were increased. Moreover, in both psoriatic groups, i.e. normo- and hyperlipidaemic, NT-proBNP concentrations were significantly higher compared to normo- and hyperlipidaemic controls, P = 0.02 and P = 0.001 respectively. A positive correlation was found between the NT-proBNP concentration and duration of psoriasis (P < 0.05).. The study findings confirmed higher NT-proBNP concentrations in psoriatic patients, which could be a useful biomarker of CV disease in both normo- and hyperlipidaemic groups.

Peripheral blood miRNAs as a biomarker for chronic cardiovascular diseases.
    Scientific reports, 2014, May-22, Volume: 4

    Vascular diseases are the most prevalent diseases worldwide. This study intended to analyze peripheral blood miRNA levels and their correlation with NT-pro-BNP and cTN-I in patients with atherosclerosis or pre-atherosclerotic conditions to build a dynamic correlation between vascular diseases and their biomarkers. Serum NT-pro-BNP and cTN-I levels were measured by their respective ELISA kits. The miRNA levels were assayed by quantitative PCR. Unique miRNA signatures were identified for both atherosclerosis and pre-atherosclerosis. The levels of miR-92a, 126, 130a, 222, and 370 levels were decreased in the peripheral blood of pre-atherosclerotic subjects. In atherosclerosis, miR-21, 122, 130a, and 211 were significantly increased whereas miR-92a, 126, and 222 were markedly decreased. Serum levels of NT-pro-BNP and cTN-I correlated with each other and increased with the progression of atherosclerosis. Moreover, the levels of cTN-I and NT-pro-BNP were positively correlated with miR-21 and negatively correlated with miR-126. Integrating specific pattern of miRNA levels with NT-pro-BNP and/or cardiac troponin may improve the diagnosis of cardiovascular diseases.

Association of natriuretic peptide polymorphisms with left ventricular dysfunction in southern Han Chinese coronary artery disease patients.
    International journal of clinical and experimental pathology, 2014, Volume: 7, Issue:10

    Left ventricular dysfunction (LVD) occurs with myocardial ischemia and coronary artery disease (CAD). The natriuretic peptide system has compensatory vasodilatory, natriuretic and paracrine effects on LVD and subsequent heart failure. The aim of this study was to investigate the relationship between natriuretic peptide polymorphisms and risk of LVD in CAD patients.. We recruited 747 consecutive Southern Han Chinese patients with angiographically confirmed CAD, 201 had a reduced left ventricle ejection fraction (LVEF ≤45%, LVD group) and 546 had a preserved left ventricle ejection fraction (LVEF >45%). The reduced and preserved LVEF groups were matched by gender and age. Taqman assays were performed to identify five polymorphisms in the NPPA-NPPB locus (rs5065, rs5063, rs632793, rs198388 and rs198389).. Single-locus analyses found no significant difference in the allele and genotype frequencies of the reduced and preserved LVEF group, even after adjusting for confounding factors. Subgroup analyses performed by hyperlipidemia (HLP) demonstrated 3 polymorphisms, rs632793 (OR = 0.31, 95% CI 0.1-0.93, P = 0.04), rs198388 (OR = 0.26, 95% CI 0.09-0.79, P = 0.02) and rs198389 (OR = 0.26, 95% CI 0.09-0.80, P = 0.02) were associated with the reduced risk of LVD. No CAD-susceptible haplotypes were identified. Multifactor dimensionality reduction analysis did not detect any gene-to-gene interactions among the five loci. Three loci (rs5063, rs632793 and rs198388) formed the best model with the maximum testing accuracy (39.89%) and cross-validation consistency (10/10).. Three NPPA-NPPB polymorphisms (rs632793, rs198388 and rs198389) were associated with reduced risk of LVD in CAD patients with HLP.

Association of serum triiodothyronine with B-type natriuretic peptide and severe left ventricular diastolic dysfunction in heart failure with preserved ejection fraction.
    The American journal of cardiology, 2012, Jul-15, Volume: 110, Issue:2

    There are well-documented changes in thyroid hormone metabolism that accompany heart failure (HF). However, the frequency of thyroid hormone abnormalities in HF with preserved ejection fraction (HFpEF) is unknown, and no studies have investigated the association between triiodothyronine (T(3)) and markers of HF severity (B-type natriuretic peptide [BNP] and diastolic dysfunction [DD]) in HFpEF. In this study, 89 consecutive patients with HFpEF, defined as symptomatic HF with a left ventricular ejection fraction >50% and a left ventricular end-diastolic volume index <97 ml/m(2), were prospectively studied. Patients were dichotomized into 2 groups on the basis of median T(3) levels, and clinical, laboratory, and echocardiographic data were compared between groups. Univariate and multivariate linear regression analyses were performed to determine whether BNP and DD were independently associated with T(3) level. We found that 22% of patients with HFpEF had reduced T(3). Patients with lower T(3) levels were older, were more symptomatic, more frequently had hyperlipidemia and diabetes, and had higher BNP levels. Severe (grade 3) DD, higher mitral E velocity, shorter deceleration time, and higher pulse pressure/stroke volume ratio were all associated with lower T(3) levels. T(3) was inversely associated with log BNP (p = 0.004) and the severity of DD (p = 0.039). On multivariate analysis, T(3) was independently associated with log BNP (β = -4.7 ng/dl, 95% confidence interval -9.0 to -0.41 ng/dl, p = 0.032) and severe DD (β = -16.3 ng/dl, 95% confidence interval -30.1 to -2.5 ng/dl, p = 0.022). In conclusion, T(3) is inversely associated with markers of HFpEF severity (BNP and DD). Whether reduced T(3) contributes to or is a consequence of increased severity of HFpEF remains to be determined.

Factors affecting the B-type natriuretic peptide levels in stroke patients.
    Annals of the Academy of Medicine, Singapore, 2010, Volume: 39, Issue:5

    This study aims to evaluate the relationship between increased B-type natriuretic peptide (BNP) levels in stroke patients and clinical parameters such as age, sex, medical history, blood pressure, Glasgow Coma Score (GCS) and National Institutes of Health Stroke Scale (NIHSS).. This is a prospective study of 123 stroke patients at the Emergency Department. The patients were divided into 3 groups according to the NIHSS scores. The analysis of the mean difference between continuous variables and plasma BNP levels was assessed using the Mann-Whitney and Kruskal-Wallis. Spearman correlation analysis was performed for BNP and other clinical parameters.. The BNP levels of patients who had a medical history of hyperlipidaemia, chronic obstructive pulmonary disease, diabetes mellitus and coronary artery disease were significantly higher than in patients without these diseases. Patients who had atrial fibrillation (AF) in their electrocardiography had significantly higher BNP levels than patients with sinus rhythm. A positive correlation was found between plasma BNP levels with age, blood urea nitrogen (BUN) and NIHSS and a negative correlation was found between plasma BNP levels and GCS. There was a significant difference between the BNP levels of NIHSS groups.. We consider that plasma BNP levels could help us in interpreting the general clinical severity, functional capacity and clinical progress of stroke patients at the time of admission in the Emergency Department. In evaluating the high BNP levels in stroke patients, we must keep in mind that age, AF, BUN and medical history can affect the BNP levels.

N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) for predicting silent myocardial ischaemia in type 2 diabetes mellitus independent of microalbuminuria.
    Diabetes/metabolism research and reviews, 2010, Volume: 26, Issue:7

    In the early identification of cardiovascular risk, it is essential to establish a biological marker for cardiac complications that is comparable to albuminuria for nephropathy. We tested the hypothesis that N-terminal pro-brain natriuretic peptide (NT-proBNP) might be a marker for silent myocardial ischaemia in diabetes.. In forty consecutively recruited subjects without evident coronary artery disease, serum NT-proBNP was measured together with multi-slice computed tomography. With patients suspected of having significant coronary artery stenosis by multi-slice computed tomography, coronary angiography was performed. Silent myocardial ischaemia was defined as the presence of significant coronary artery stenosis with more than 50% luminal narrowing by angiography.. Thirteen patients (32.5%) had silent myocardial ischaemia. NT-proBNP levels were significantly higher in these patients (181.1 ± 43.8 versus 55.2 ± 9.7 pg/mL, p < 0.005) but HbA(1c), lipid profiles, and creatinine were similar in the two groups. Moreover, log NT-proBNP was identified as an independent predictor of silent myocardial ischaemia (R(2) = 0.502, p < 0.05) after adjustment for HbA(1c), creatinine, albuminuria, hypertension, hyperlipidaemia, or smoking. After stratifying patients by NT-proBNP, the upper tertile compared to the lowest tertile was significantly associated with silent myocardial ischaemia (odds ratio: 26.7, p < 0.05). Receiver operation characteristics analysis with a cut-off value of 52 pg/mL showed 92% sensitivity and 75% specificity for predicting silent myocardial ischaemia (positive predictive value 64.7%, negative predictive value 94.3%).. The outstandingly high negative predictive value of NT-proBNP enables us to focus on diabetic patients with occult coronary disease, independently of microalbuminuria.

Heart failure may be associated with the onset of ischemic stroke with atrial fibrillation: a brain natriuretic peptide study.
    Journal of the neurological sciences, 2009, Jun-15, Volume: 281, Issue:1-2

    Congestive heart failure is a risk factor for ischemic stroke. Brain natriuretic peptide (BNP) is used as a biological marker of heart failure. We hypothesized that heart failure was associated with the onset of ischemic stroke patients with atrial fibrillation (AF).. Between June 2006 and December 2007, we prospectively enrolled consecutive acute ischemic stroke patients with AF within 24 h of onset. Plasma BNP was measured twice, on admission and on days 28 or at discharge. As a control, we measured plasma BNP of chronic phase of stroke outpatients with AF. We investigated whether plasma BNP was elevated in the acute phase of stroke.. One hundred and nine patients (58 females; mean age, 76.3 years) were enrolled in the present study. Mean+/-SD of NIHSS score on admission and mRS score at discharge were 12.6+/-8.3 and 3.7+/-1.8, respectively. The interval from stroke onset to plasma BNP measurement on admission was 6.8+/-6.3 h. Moreover, follow up BNP was measured at mean of 26+/-9 days after stroke onset. The plasma BNP level in the acute phase of stroke was significantly higher than that of the subacute phase of stroke (median (interquartile range, IQR) 299.0 (176.8-469.5) vs. 149.5 (68.1-347.0) pg/ml, p<0.001). There was no significant difference in plasma BNP level between the subacute phase of stroke and control group (median (IQR) 149.5 (68.1-347.0) vs. 165.0 (64.6-224.0) pg/ml, p=0.543).. Plasma BNP was elevated in the acute phase of stroke. Heart failure may be associated with the onset of ischemic stroke patients with AF.

Prognostic accuracy of B-natriuretic peptide measurements and coronary artery calcium in asymptomatic subjects (from the Early Identification of Subclinical Atherosclerosis by Noninvasive Imaging Research [EISNER] study).
    The American journal of cardiology, 2009, Nov-01, Volume: 104, Issue:9

    B-type natriuretic peptide (BNP) has prognostic implications in patients with acute and chronic cardiac symptoms. Its prognostic role in asymptomatic patients with evidence of subclinical disease remains unclear. The population of this study included 2,458 asymptomatic adults (47% women) with an average Framingham risk score of 8.8 +/- 7% who underwent computed tomographic evaluation of coronary artery calcium (CAC). BNP levels were measured using the Triage CardioProfilER panel method. Cox proportional-hazards models were used to estimate time to a cardiovascular (CV) event (n = 84; 16 deaths, 12 myocardial infarctions, 8 cerebrovascular accidents or transient ischemic attacks, and 48 diagnoses of incident symptomatic coronary disease). Relative risk was calculated. The median follow-up time was 3.9 years (25th and 75th percentiles 2.9 and 4.0). The relative hazard for a CV event ranged from 2.2 to 7.5 for BNP values of 40 to 99.9 and > or =100 pg/ml (p <0.0001) compared to BNP <40 pg/ml. Similarly, CAC score was also highly predictive of CV events, with elevated hazard ratios of 2.8- to 48.7-fold for scores of 11 to 100 to > or =1,000 (p <0.0001) compared to no CAC. In a stepwise model, BNP was the second greatest estimator of CV outcomes (p = 0.016) after CAC (p <0.0001), even in models that included blood pressure and age. Hypertension, age > or =65 years, and CAC contained 28.4%, 40.7%, and 56.8%, respectively, of BNP risk. The combination of BNP > or =100 pg/ml and CAC score > or =400 identified 52.4% and 35.7% of CV events in patients with hypertension and in elderly patients beyond the Framingham risk score. In conclusion, BNP and CAC are independently predictive of CV events.

Hyperlipidaemia induced by a high-cholesterol diet leads to the deterioration of guanosine-3',5'-cyclic monophosphate/protein kinase G-dependent cardioprotection in rats.
    British journal of pharmacology, 2009, Volume: 158, Issue:6

    Hyperlipidaemia interferes with cardioprotective mechanisms, but the cause of this phenomenon is largely unknown, although hyperlipidaemia impairs the cardioprotective NO-cGMP system. However, it is not known if natriuretic peptide-cGMP-protein kinase G (PKG) signalling is affected by hyperlipidaemia. Therefore, we investigated the cardioprotective efficacy of cGMP-elevating agents in hearts from normal and hyperlipidaemic rats.. Male Wistar rats were rendered hyperlipidaemic by feeding with 2% cholesterol-enriched chow for 12 weeks. Hearts isolated from normal and hyperlipidaemic rats were perfused (Langendorff mode) and subjected to 30 min occlusion of the left main coronary artery, followed by 120 min reperfusion. 8-Br-cGMP (CG, 10 nM), B-type natriuretic peptide-32 (BNP, 10 nM), S-nitroso-N-acetyl-penicillamine (SNAP, 1 microM) were perfused from 10 min prior to coronary occlusion until the 15th min of reperfusion. Infarct size (% of ischaemic risk zone) was determined by triphenyltetrazolium staining.. Treatment with CG, SNAP or BNP decreased infarct size significantly in normal hearts from its control value of 41.6 +/- 2.9% to 15.5 +/- 2.4%, 23.3 +/- 3.0% and 25.3 +/- 4.6%, respectively (P < 0.05). Protection by BNP was abolished by co-perfusion of PKG inhibitors KT5823 (600 nM) or Rp-8pCPT-PET-cGMPs (1 microM), confirming its PKG dependence. In hearts from hyperlipidaemic rats, CG, SNAP or BNP failed to decrease infarct size. Hyperlipidaemia did not alter basal myocardial PKG content, but decreased its activity as assessed by phosphorylation of cardiac troponin I.. This is the first demonstration that defects in the cardioprotective cGMP-PKG system could be a critical biochemical anomaly in hyperlipidaemia.

[Clinical manifestations and outcome of acute myocardial infarction in young adults treated with primary coronary angioplasty].
    Journal of cardiology, 2006, Volume: 48, Issue:1

    This study investigated the differences in presentation, complications, and outcome of young patients with acute myocardial infarction compared to other patients.. Our series of 379 consecutive patients with acute myocardial infarction, who were admitted within 12 hr of onset and successfully reperfused by primary percutaneous coronary intervention, included 28 (7.4%) young patients (< 50 years).. There were significantly more male patients, current smokers, and hyperlipidemia in the young group than in the other patients (p < 0.01). The levels of acute phase brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) were significantly lower (BNP: 128 +/- 103 vs 379 +/- 470 pg/ml, p = 0.009, ANP: 17 +/- 11 vs 66 +/- 81 pg/ml, p = 0.004) and peak creatine kinase value was significantly higher (3,824 +/- 3,459 vs 2,413 +/- 2,023 IU/l, p = 0.009) in the young group than in the other patients. The increase (chronic phase-acute phase) of left ventricular ejection fraction was significantly better in the young group (8 +/- 9% vs 4 +/- 10%, p < 0.05). There were significantly fewer patients with ventricular arrhythmia in the young group than in the other patients (10.7% vs 33.0%, p = 0.04). The cardiac mortality rate in the first 6 months was only 3.6% in the young group.. Young patients with acute myocardial infarction, in spite of higher peak creatine kinase value, seemed to have excellent prognosis, with lower BNP and good recovery of left ventricular ejection fraction.

[Clinical manifestations and acute myocardial infarction in women treated with primary coronary angioplasty].
    Journal of cardiology, 2006, Volume: 48, Issue:3

    The differences in presentation, complications, and outcome of acute myocardial infarction treated with primary coronary angioplasty were compared in male and female patients.. Consecutive patients with acute myocardial infarction who were admitted within 12 hr of onset underwent primary percutaneous coronary intervention, including 120 female (31%) and 264 male (69%) patients.. There were significantly more patients with diabetes mellitus (42% vs 31%, p = 0.03), and hyperlipidemia(56% vs 38%, p = 0.001), and fewer patients with current smoking (10% vs 60%, p < 0.0001) in the female group than in the male group (p < 0.01). The female group was significantly older (75 +/- 11 vs 67 +/- 12 years, p < 0.0001). The value of acute phase brain natriuretic peptide was significantly higher (483 +/- 543 vs 306 +/- 404 pg/ml, p = 0.001), and peak creatine kinase value was significantly lower (1,743 +/- 1,732 vs 2,855 +/- 2,997 IU/l, p = 0.0003) in the female group than in the male group. Both Killip's classification on admission (p = 0.04) and Thrombolysis in Myocardial Infarction grade soon after mechanical reperfusion therapy (p = 0.03) were significantly worse in the female group. There were significantly more patients with heart failure in the female group (40% vs 27%, p = 0.04). The cardiac mortality rates during 6 months was significantly higher in the female group (11% vs 5%, p = 0.02). However, multivariate analysis showed that female sex was not an independent predictor of cardiac death.. Female patients with acute myocardial infarction seemed to have a poor prognosis, in spite of lower peak creatine kinase value and higher brain natriuretic peptide value. The reasons for poorer outcomes in women were considered to be patient background, such as higher age and diabetes mellitus, and condition of heart failure on admission.

Characterization of plasma brain natriuretic peptide level in patients with type 2 diabetes.
    Endocrine journal, 2005, Volume: 52, Issue:3

    This study investigates whether the plasma brain natriuretic peptide (BNP) level is increased by the clinical traits of diabetes, including its complications, and whether these levels are affected by the presence of other combined diseases such as hypertension, hyperlipidemia, and coronary heart disease (CHD) in patients with diabetes. In 223 patients with Type 2 diabetes, the mean value of plasma BNP reached 32.3+/-4.1 pg/mL. The levels significantly increased with age, hypertension, and CHD but not with the duration of diabetes, HbA1c level, or hyperlipidemia. With regard to the type of therapy, the BNP levels were significantly lower in the combinations of both sulfonylurea and metformin and sulfonylurea and pioglitazone than those in insulin alone. In addition, the BNP levels in the group with diabetic complications, including retinopathy and nephropathy, and macroalbuminuria were significantly elevated in comparison with those without these complications and macroalbuminuria. Interestingly, however, no difference was observed between these groups after removal of the values in patients with CHD. These results have clarified that the plasma BNP levels in diabetic patients could increase only by the progression of macrovascular diseases, such as CHD, but not by the current diabetic control or diabetic microvascular complications.
