We examined the effect of renal dysfunction on B-natriuretic peptide (BNP), N-terminal (NT)-proBNP, and their molar ratio at varying severities of cardiac function in 94 Thai patients with chest pain (52 men; 32 women), also measuring creatinine and left ventricular ejection fraction (LVEF). Renal function was classified into 5 stages by estimated glomerular filtration rate. The molar NT-proBNP...

BACKGROUND N-terminal pro-brain natriuretic peptide (NT-proBNP) is associated with an increased risk of cardiac insufficiency, which possibly leads to heart failure. However, the relationship between resting heart rate and NT-proBNP is unclear. OBJECTIVE This study focuses on this relativity between resting heart rate and plasma NT-proBNP levels in a surveyed community-based population. MET...

patients and methods this cross-sectional study included a total of 120 adult predialysis ckd patients. forty patients were allocated in each predialysis ckd group of stages 3, 4, and 5. serum ctnt and hs-crp, plasma nt-probnp, and single spot urine albumin creatinine ratio (acr) were measured. ultrasonographic examination of carotid artery was done with 7.5 mhz linear probe in b mode ultrasono...

N-terminal pro-brain natriuretic peptide (NT-proBNP) is a routinely used prognostic parameter in patients with pre-capillary pulmonary hypertension (PH). As it accumulates in the presence of impaired renal function, the clinical utility of NT-proBNP in PH patients with concomitant renal insufficiency remains unclear. In a retrospective approach, patients with pre-capillary PH (group I or IV) an...

BACKGROUND Amino-terminal pro-B-type natriuretic peptide (NT-proBNP) has emerged as predictor of mortality endpoints in cardiac disease. In contrast, the prognostic value of NT-proBNP in patients with peripheral arterial disease (PAD) is unclear. Therefore, we aimed to evaluate the capability of NT-proBNP as a marker for long-term prognosis in atherosclerotic PAD. METHODS We obtained NT-proBN...

Pulmonary hypertension (PH) is an important cause of heart failure in chronic obstructive pulmonary disease (COPD). The pro brain natriuretic peptide N-terminal (NT-proBNP) has been suggested as a noninvasive marker to evaluate ventricular function. However, there is no evidence to support the use of NT-proBNP in monitoring the benefits of vasodilators in COPD induced PH. Thus, we used NT-proBN...

BACKGROUND We compared the performance of different natriuretic peptides to diagnose mild forms of left ventricular dysfunction (LVD) and investigated the influence of measuring B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) with different assays on the diagnostic performance of these markers. METHODS We measured BNP (Triage BNP), NT-proBNP (Biomedica), and N-terminal pro-...

INTRODUCTION N-terminal pro-B-type natriuretic peptide (NT-proBNP) predicts adverse cardiac outcome in patients undergoing vascular surgery. However, several conditions might influence this prognostic value, including anemia. In this study, we evaluated whether anemia confounds the prognostic value of NT-proBNP for predicting cardiac events in patients undergoing vascular surgery. METHODS A d...

BACKGROUND Plasma proBNP levels are increased in patients with acute myocardial infarction. Previous studies have shown conflicting data on the effect of transient myocardial ischemia on plasma BNP levels. We designed the current study to examine plasma proBNP levels in patients with transient myocardial ischemia during a percutaneous coronary intervention (PCI). This study was to study plasma ...
