Brain Natriuretic Peptide (BNP)

Intravenous

Overview

Brain natriuretic peptide, despite its name, is a 32-amino acid hormone secreted predominantly by ventricular cardiomyocytes in response to ventricular stretch and pressure overload. It activates guanylyl cyclase A receptors to promote vasodilation, natriuresis, and suppression of the renin-angiotensin-aldosterone and sympathetic nervous systems.

Mechanism of Action

BNP and its N-terminal fragment (NT-proBNP) are widely used as diagnostic and prognostic biomarkers in heart failure..

Research Summary & Key Findings

Nesiritide, a recombinant form of human BNP, received FDA approval in 2001 for acute decompensated heart failure based on hemodynamic improvement in clinical trials. BNP measurement is incorporated into heart failure diagnostic guidelines following extensive validation studies, including the Breathing Not Properly study (NEJM, 2002), which established its utility in emergency department assessment of dyspnea.

Clinical Status
