Objectives To explore levels of the brain natriuretic peptide (BNP) and how these associate with the cardiac abnormalities recently identified in chronic fatigue syndrome (CFS). Methods Cardiac magnetic resonance examinations were performed using 3T Philips Intera Achieva scanner (Best, Netherlands) in CFS (Fukuda) participants and sedentary controls matched group wise for age and sex. BNP wa...

OBJECTIVE To determine the utility of B-type natriuretic peptide (BNP) in the diagnosis of congestive heart failure (CHF) in patients presenting with dyspnea to an emergency department (ED). METHODS Seventy patients presenting with dyspnea to an ED from April to July 2001 were included in the study. Mean age was 72+/-16 years and 33 (47%) were male. BNP was measured in all patients at the mom...

B-type natriuretic peptide (BNP) is a peptide hormone of myocardial origin with significant cardioprotective properties. Patients with myocardial ischemia present with high levels of BNP in plasma and elevated expression in the myocardium. However, the molecular mechanisms of BNP induction in the ischemic myocardium are not well understood. The aim of the investigation was to assess whether myo...

BACKGROUND In heart failure, brain-type natriuretic peptide (BNP) is elevated and the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) downregulated. We previously showed that preload-induced SERCA-upregulation is suppressed by exogenous BNP. METHODS AND RESULTS Here we tested the hypothesis that afterload and neurohumoral activation would counterregulate preload-dependent SERCA upregulation thro...

AIMS Comparison of the value of echocardiography and B-type natriuretic peptide (BNP) in monitoring response to treatment in patients admitted for acute heart failure (HF). METHODS AND RESULTS Ninety-five consecutive patients admitted with acute HF underwent bedside Doppler echocardiography and BNP measurements on admission, after 24 h of intravenous treatment, and at day 7. We then studied t...

Background Respiratory Distress (RD) is a life-threatening respiratory failure. This study aimed to evaluate the diagnostic value of N-terminal prohormone of brain natriuretic peptide (NT-pro-BNP) in distinguishing respiratory and heart diseases in neonates. Materials and Methods Hundred fifty neonates aged 2-3 days randomly collected from those who hospitalized in the related ward of the Ali ...

Background N-terminal pro–B-type natriuretic peptide (NT-proBNP) is a marker to evaluate the cardiac involvement in thalassemia. We aimed to evaluate conventional and tissue Doppler echocardiography findings and its relation to plasma NT-pro BNP, Ferritin and Iron levels in beta-thalassemia patients. Materials and Methods This study performed on 164 participants equal of major beta- thalassemi...

INTRODUCTION Multiple studies found a significant correlation between B-type natriuretic peptide (BNP) level and clinical severity of heart failure (HF). We aim to study the ability of a single BNP measurement to predict the degree of congestion in acute systolic HF. METHODS Patients enrolled in the ESCAPE trial who were admitted with acute systolic HF were divided into tertiles according to ...

UNLABELLED Cardiotoxicity is a dose-limiting side-effect of cancer chemotherapeutics such as anthracyclines. The drug-induced cardiac toxicity is currently monitored with repeated assessments of the left ventricular ejection fraction (LVEF) using multigated equilibrium radionuclide ventriculography (MUGA) or echocardiography. However, the plasma cardiac biomarker B-type natriuretic peptide (BNP...
