The effect of altering haemodynamics on the plasma concentrations of natriuretic peptides in heart failure

摘要

Background Natriuretic peptide levels reflect haemodynamics in patients with heart failure and may serve as biochemical markers of cardiac filling pressures. The purpose of this study was to detect differences in the kinetic profile between atrial natriuretic peptide (ANP), B-type natriuretic peptide (BNP) and their N-terminal fragments N-ANP and N-BNP, in response to rapid and persistent vasodilatation.
