The levels and pathophysiological role of amino terminal C-type natriuretic peptide in heart failure are unknown. The potential of plasma amino-terminal C-type natriuretic peptide (N-CNP) as a marker of cardiac function was investigated in symptomatic patients. In 305 patients with recent-onset dyspnea and/or peripheral edema, presenting to primary care, assay of plasma amino-terminal C-type na...

The concept of the heart as an endocrine organ arises from the observation that the atrial cardiomyocytes in the mammalian heart display a phenotype that is partly that of endocrine cells. Investigations carried out between 1971 and 1983 characterised, by virtue of its natriuretic properties, a polypeptide referred to atrial natriuretic factor (ANF). Another polypeptide isolated from brain in 1...

We have compared the expression of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) genes in various human tissues using a quantitative polymerase chain reaction technique. Tissues of three human subjects, obtained at autopsy, were analyzed. BNP transcripts could be detected in the central nervous system, lung, thyroid, adrenal, kidney, spleen, small intestine, ovary, uterus...

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) shares structural and functional similarities to atrial natriuretic peptide (ANP). Although BNP and ANP interact with the same biologically active guanylate cyclase-coupled receptor, recent reports conflict with regard to the biological actions of exogenous BNP in sodium-retaining and edematous states. We studied the biological actions of BNP in normal dogs (n = ...

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...

fter the structure of atrial natriuretic peptide was established,1 a Japanese group isolated the brain (also known as B-type) natriuretic peptide (BNP) from porcine brain extracts in 1988 by monitoring the relaxant activity of the chick rectum.2 Subsequent studies demonstrated that BNP is a cardiac hormone that is mainly expressed in the heart, where its concentration is considerably higher tha...

Aim. To assess laboratory markers of hemodynamic status in patients with moderate to severe COVID-19. Materials and Methods. Here we examined 15 COVID-19 16 critically ill patients. The control group consisted 20 healthy volunteers. levels endothelin-1, brain natriuretic peptide (BNP), N-terminal pro-brain (NT-proBNP) were measured by enzyme-linked immunosorbent assay. amounts nitrites (NO 2 ) ...

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...
