OBJECTIVE To compare the concentration of plasma atrial natriuretic peptide in patients with acute myocardial infarction with a healthy population and to determine whether a raised concentration of plasma atrial natriuretic peptide at admission was a predictor of mortality after acute myocardial infarction. DESIGN Patients with acute myocardial infarction were divided into a group with no con...

Many studies have described the role of B-type natriuretic peptide or its amino-terminal byproduct (NT-pro-B-type natriuretic peptide) in clinical practice, including several published or ongoing randomized clinical trials. However, the debate over natriuretic peptide testing continues, mostly related to the appropriateness of testing as decision support for the management of heart failure. The...

OBJECTIVES To determine and compare the diagnostic accuracy of serum natriuretic peptide levels (B type natriuretic peptide, N terminal probrain natriuretic peptide (NTproBNP), and mid-regional proatrial natriuretic peptide (MRproANP)) in people presenting with acute heart failure to acute care settings using thresholds recommended in the 2012 European Society of Cardiology guidelines for heart...

The natriuretic peptides (NPs) are a family of related hormones that play important roles in the cardiovascular homeostasis, cell growth and neuroendocrine functions. Recently, they have emerged as potentially important clinical biomarkers in heart failure. The heart secretes two major natriuretic peptides: atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), while C-type natri...

Background: Plasma concentrations of atrial natriuretic peptides are correlated with atrial pressures, as are left ventricular ejection fraction and left ventricular filling abnormalities. Aims: This study investigated the relation of atrial natriuretic peptides to both left ventricular systolic and diastolic function in heart failure. Methods: Plasma concentrations of atrial natriuretic peptid...

Crotalus oreganus abyssus is a rattlesnake that is usually found in the Grand Canyon, United States of America. Knowledge regarding the composition of C. o. abyssus venom is scarce. New natriuretic peptides (NPs) have been isolated and characterized from the venoms of members of the Crotalinae family. The NP family comprises three members, ANP (atrial natriuretic peptide), BNP (b-type natriuret...

We examined a possible interaction between the calcium entry blocker nifedipine and atrial natriuretic peptide on blood pressure and natriuresis in anesthetized rabbits. The administration of atrial natriuretic peptide (0.05 micrograms/kg/min) produced a significant decrease in mean arterial pressure. Similar reductions in blood pressure were obtained during the administration of nifedipine (1....
