A prospective study was performed to evaluate the diagnostic accuracy of N-terminal-pro-B-type natriuretic peptide (NT-proBNP) levels, measured simultaneously in serum and pleural fluid, in identifying pleural effusions due to heart failure. Pleural fluid and serum samples from all patients presenting for thoracentesis between April 2004 and May 2005 were simultaneously collected. The discrimin...

BACKGROUND Screening for patients with asymptomatic left ventricular dysfunction is of considerable importance because they may benefit from early treatment with angiotensin converting enzyme inhibitors. It has been suggested that atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and cyclic guanosine 3',5'-monophosphate (cGMP) might be useful markers for screening. OBJECTIVE ...

INTRODUCTION Brain natriuretic peptide (BNP) levels correlate with functional capacity in patients with heart failure. Autonomic dysfunction and baro-chemo reflex balance play a role in conditioning exercise tolerance and chronotropic competence in heart failure. In this study we examined the relationship between N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and heart rate (HR) response...

Natriuretic peptides (NUPs) are the strongest predictors of poor prognosis in patients with heart failure (HF). Single-nucleotide polymorphisms (SNPs) rs198389 NPPB gene and rs5068 NPPA associated altered levels NUP. The role candidate activity NUP system association NPPA/ SNPs risk cardiovascular disease (CVD) individuals HF atrial fibrillation (AF) is not well understood. study aims to evalua...

Serum level of the N-terminal of the prohormone brain natriuretic peptide (NT-proBNP) is an important factor in pregnancy-induced hypertension. The purpose of the present study was to evaluate the clinical significance of serum NT-proBNP level in pregnant hypertensive patients with retinopathy. Patients divided into gestational hypertension, mild preeclampsia, and serious preeclampsia groups un...

Since the initial observation that elevated cardiac troponin T levels are closely associated with mortality in acute pulmonary embolism,1 several reports have confirmed the prognostic role of cardiac troponins in this setting.2,3 More recently, yet another group of biomarkers, the natriuretic peptides B-type natriuretic peptide (BNP) and N-terminal-pro-B-type natriuretic peptide (NT-proBNP), em...

INTRODUCTION N-terminal pro brain natriuretic peptide (NT-proBNP) is a cardiac biomarker that has recently shown to be of diagnostic value in a diagnosis of decompensated heart failure, acute coronary syndromes and other conditions resulting in myocardial stretch. We sought to study whether sepsis-induced myocardial dilation would result in an elevation of NT-proBNP. METHOD Serum NT-proBNP me...

OBJECTIVE We recently showed that plasma concentration of N-terminal atrial natriuretic peptide (Nt-proANP) is strongly directly related to salt sensitivity. The aims of the present study were to test (i) whether plasma concentration of N-terminal brain natriuretic peptide (Nt-proBNP) is related to salt sensitivity and (ii) whether Nt-proANP, as a marker of salt sensitivity, differs between typ...

Background Heart failure is a major cause of death in thalassemia. The study aimed to determine the diagnostic value of N Terminal Pro B Type Natriuretic Peptide (NT-pro BNP), to early diagnose the cardiac involvement in beta- thalassemia major patients. Materials and Methods  80 thalassemia patients aged 7 to 18 years old (patients group), and 80 healthy age and gender matched controls were ...

BACKGROUND The inferior vena cava (IVC) diameter and degree of inspiratory collapse are used as echocardiographic indices in the estimation of right atrial pressure. Brain-natriuretic peptides (BNPs) are established biomarkers of myocardial wall stress. There is no information available regarding the association between the IVC diameter and BNPs in patients with heart failure and various degree...
