B-type natriuretic peptide (BNP) is a cardiac neurohormonal that is selectively secreted from the ventricular granule membrane when ventricular capacity is expanded and pressure overload is experienced. It has been demonstrated that patients with symptomatic left ventricular dysfunction, BNP Increased concentration. BNP levels correlated with left ventricular filling pressure, NYHA classification and prognosis. The purpose of this study was to determine if BNP levels predict anapoiesis
