Cardiac
NT-proBNP
NT-proBNP is released by the heart ventricles in response to increased wall stress from volume or pressure overload. It is the primary biomarker used to diagnose and monitor heart failure.
Levels rise with age, kidney disease, and atrial fibrillation. Very low levels effectively rule out heart failure.
What It Measures
N-terminal pro-B-type natriuretic peptide from cardiac ventricles.
