N-Terminal Prohormone Brain Natriuretic Peptide as a Marker for Detecting Low Functional Class Patients and Candidates for Cardiac Transplantation: Linear Correlation With Exercise Tolerance

NT Pro BNP plasma levels correlate both with LVEF and aerobic capacity, can predict low functional cardiopulmonary exercise capacity in patients with impaired left ventricular function, and are useful for detecting candidates for cardiac transplantation.
