NT-proBNP, or N-terminal pro-brain natriuretic peptide, is a biomarker used in medicine to assess heart function. It is a precursor molecule to B-type natriuretic peptide (BNP), which is released by the heart in response to increased pressure and volume overload, particularly in conditions like heart failure.

The NT-proBNP test measures the levels of this peptide in the blood. Higher levels of NT-proBNP typically indicate greater stress on the heart, which can be due to conditions such as heart failure, myocardial infarction, or pulmonary hypertension.
