Abstract

To investigate whether percent achieved of predicted peak exercise oxygen uptake (%VO(2 max)) and recovery of oxygen consumption after exercise may provide prognostic information in chronic heart failure (CHF), we prospectively studied 196 patients with mild to moderate CHF. The following variables were examined: age, etiology of CHF, functional class, ejection fraction (EF), peak exercise oxygen uptake normalized for body weight (VO(2 max)), %VO(2 max) time to reach 50% of the peak oxygen uptake after exercise (T(1/2)VO(2 max)), presence of nonsustained ventricular tachycardia (NSVT) and inability to take ACE-inhibitors. VO(2 max) was the most powerful predictor of cardiac death (P
