background one of the main components involving in the pathogenesis and prognosis of sepsis and septic shock is natriuretic peptide. hemodynamic changes in sepsis or septic shock might explain increased plasma levels of these peptides circulations. objectives the present study aimed to assess the value of brain natriuretic peptide (bnp) in prediction of sepsis state and its related morbidity. w...

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)...

BACKGROUND AND PURPOSE Diagnosis of paroxysmal atrial fibrillation (AF) can be challenging, but it is highly relevant in patients presenting with sinus rhythm and acute cerebral ischemia. We aimed to evaluate prospectively whether natriuretic peptide levels and kinetics identify patients with paroxysmal AF. METHODS Patients with acute cerebral ischemia were included into the prospective obser...

Cardiac natriuretic peptides, especially amino terminal pro-Brain Natriuretic Peptide (NT-proBNP), are emerging as powerful circulating markers of cardiac function. However, the in vivo secretion and elimination (t1/2) of these peptides during acute volume overload have not been studied. We present the first report of the secretion and elimination of cardiac natriuretic peptides, based on decon...

C ardiac transplantation is an important treatment option for those patients with end stage heart failure who have failed to respond to disease modifying treatment. However, cardiac transplantation is not without risk, with the one year mortality around 19%, and identifying patients at the highest risk of death is notoriously difficult. Brain natriuretic peptide (BNP) and the N-terminal portion...

The aim of the current study was to investigate whether alterations in N-terminal pro brain natriuretic peptide (NT-proBNP) reflect changes in right ventricular structure and function in pulmonary hypertension patients during treatment. The study consisted of 30 pulmonary hypertension patients; 15 newly diagnosed and 15 on long-term treatment. NT-proBNP, right heart catheterisation and cardiac ...

Patients with idiopathic pulmonary arterial hypertension usually undergo acute vasodilator tests with nitric oxide (NO) for haemodynamic evaluation and therapeutical planning. The aim of this study was to evaluate the link between the variation of N-terminal (NT)-pro-brain natriuretic peptide (BNP) levels and haemodynamic parameters during the acute vasodilator test. A total of 22 idiopathic pu...

Brain natriuretic peptide (BNP) is a peptide hormone secreted by cardiomyocytes in response to atrial or ventricular wall stretch and/or pressure overload. It promotes a number of systemic effects, including vasodilatation, increase in urinary output and sodium excretion, as well as inhibition of the sympathetic nervous system and the renin–angiotensin–aldosterone system. Plasma BNP levels have...

background: serum n-terminal pro-brain natriuretic peptide (nt-probnp), a polypeptide secreted by ventricular myocytes in response to stretch, was suggested as a predictor of adverse prognosis of the acute coronary syndrome (acs). we examined the association between nt-probnp level and angiographic findings in acs patients to determine whether it could be used as a predictor of the severity of ...

background: brain type natriuretic peptide (bnp) is a cardiac hormone that is secreted mainly by the ventricles in response to volume expansion and pressure load. it can predict post-operative complications after heart surgery in adults. we sought to investigate the prognostic value of bnp in children after heart surgery. methods: we measured the bnp serum levels in 96 children with congenital ...
