AM

Adrenomedullin is a 52-amino-acid vasoactive peptide originally isolated from human pheochromocytoma. It is a potent vasodilator acting through CGRP receptors, promotes natriuresis, reduces inflammation, protects vascular endothelial barrier function, and enhances wound healing. Circulating AM levels rise in heart failure, sepsis, and critical illness — making it both a biomarker and emerging therapeutic target.
