Natriuretic peptide.B prohormone N-Terminal

NT-proBNP (N-terminal pro B-type natriuretic peptide) is a hormone released by the heart in response to strain or stress. This test measures NT-proBNP levels in blood, serving as a marker of heart function and heart failure risk. Elevated levels indicate the heart is working harder than normal, suggesting heart failure, hypertension, or other cardiac stress. NT-proBNP is a sensitive indicator of left ventricular dysfunction and is used for screening, diagnosis, and monitoring of heart failure. Lower levels generally indicate better cardiac health.
