Peptides for Cardiac Biomarker
Overview
2 research peptides are currently studied for cardiac biomarker. This guide ranks them by evidence strength and covers their mechanisms, safety profiles, and current clinical status.
Atrial Natriuretic Peptide — Approved in Japan / Established Biomarker
Evidence Rating: B Category: Cardiovascular / Natriuretic
Atrial natriuretic peptide (ANP) is a 28-amino-acid hormone (MW ~3080 g/mol) secreted primarily by atrial cardiomyocytes in response to atrial stretch from volume overload. It is a key regulator of blood volume, sodium balance, and blood pressure. A recombinant form, carperitide (hANP), is approved ...
Key claims: Reduces pulmonary congestion and dyspnea in acute heart failure; Promotes natriuresis and diuresis.
B-type Natriuretic Peptide — Established Biomarker / Therapeutic Basis
Evidence Rating: B Category: Cardiovascular / Natriuretic
B-type natriuretic peptide (BNP) is a 32-amino-acid cardiac hormone (MW ~3464 g/mol) secreted primarily by ventricular cardiomyocytes in response to myocardial wall stress from volume overload or pressure overload. It is both a critical diagnostic biomarker for heart failure (BNP/NT-proBNP assays) a...
Key claims: BNP/NT-proBNP levels accurately diagnose heart failure; BNP-guided therapy may improve heart failure outcomes.
