Brain natriuretic peptide (BNP), also known as B-type natriuretic peptide, is a hormone secreted by cardiomyocytes in the heart ventricles in response to stretching caused by increased ventricular blood volume. BNP is named as such because it was originally identified in extracts of pig brain.
Brain natriuretic peptide - Measurement. 1  BNP and NT-proBNP are measured by immunoassay. 2  The main clinical utility of either BNP or NT-proBNP is that a normal level rules out acute heart failure in the emergency setting. 3  Either BNP or NT-proBNP can also be used for screening and prognosis of heart failure.
