pro-brain natrituretic peptide

pro-brain natrituretic peptide

An inactive prohormone peptide released from stretched cardiac muscle cells. The prohormone splits off the active BNP and the inactive n-terminal fragment. Levels of the latter have been found to be an effective prognostic marker of the long-term mortality risk in people with coronary artery disease.
