Background Although the left ventricle is the major site of BNP secretion in response to cardiac pressure or volume overload, the myocytes of both atria and ventricles secrete B- type natriuretic peptide (BNP). This study aimed to assess and compare the plasma levels of BNP in common pediatric cardiac diseases to clarify its pathophysiological role and evaluate its po...

acute dyspnea is a common cause of hospitalization in emergency departments (ed).distinguishing the cardiac causes of acute dyspnea from pulmonary ones is a major challenge for responsible physicians in eds. this study compares the characteristics of bedside ultrasonography with serum level of blood natriuretic peptide (bnp) in this regard. methods: this diagnostic accuracy study compares bedsi...

conclusions the results of the current study suggested that spinal anesthesia plus intravenous patient-controlled analgesia have the most favorable cardiac effects regarding postoperative levels of pro-bnp. results there was no difference between three groups for basic characteristics and variables and baseline pro-bnp levels; however, postoperative pro-bnp levels in groups a, b, and c were res...

Introduction: The aim of this study was to evaluate the effects of aerobic exercise on brain natriuretic peptide (BNP) and C-reactive protein (CRP) levels in women with cardiovascular diseases. Materials and Methods: In this semi experimental study, thirty female patients with at least one coronary artery stenosis (more than70%) were chosen and divided into two groups of aerobic training (n=15)...

Heart failure remains a major medical and social challenge despite the extraordinary progress in its diagnosis and treatment during the last 20 years. As a matter of fact, social factors such as the ageing of the population and the increase in longevity, both attributable to new treatments, will contribute to increase the burden of heart failure in future years. More than ever, we are in need o...

Recent studies support the speculation that different molecular forms of the cardiac hormone BNP with differential biological activity may circulate in heart failure and be detected by conventional assays. In the current study we determined the ability of 3 widely used conventional assays to detect these different forms thought to circulate in heart failure. We also evaluated the ability of pro...

objectivethis study aimed to assess brain natriuretic peptide in early diagnose of cardiac function in children with congenital heart diseases.methodologythis study was performed on children with chd and healthy. severity of heart failure modified ross classification system was used for grouping patients in four classes. for all participants, height, weight and head circumference were measured....

BACKGROUND Multiple B-type natriuretic peptide (BNP) fragments circulate in patients with heart failure (HF) but the types and relative quantities, particularly in relation to bioactive BNP 1-32, remain poorly defined. The purpose of the study was to relate clinically available BNP values with quantitative information on the concentration of pre-secretion and post-processed fragments of BNP det...

Bovine Neonatal Pancytopenia (BNP), a bleeding syndrome of neonatal calves, is caused by alloantibodies absorbed from the colostrum of particular cows. A commercial BVD vaccine is the likely source of alloantigens eliciting BNP associated alloantibodies. We hypothesized that the rare occurrence of BNP in calves born to vaccinated dams could be associated with genetic differences within dams and...

BACKGROUND Analysis of plasma B-type natriuretic peptide (BNP) has suggested the in vivo formation of a truncated form, BNP (3-32), also called des-SerPro-BNP. The objectives of this study were to investigate (a) whether BNP and other natriuretic peptides are truncated by dipeptidyl-peptidase IV (DPP IV/CD26; EC 3.4.14.5) and (b) whether this truncation affects the susceptibility to cleavage by...
