Baseline and Exercise Predictors of V˙O2peak in Systolic Heart Failure Patients: Results from SMARTEX-HF

Purpose This study aimed to investigate baseline, exercise testing, and exercise training–mediated predictors of change in peak oxygen uptake (V˙O 2peak ) from baseline to 12-wk follow-up (ΔV˙O 2peak ) in a post hoc analysis from the SMARTEX Heart Failure trial. Methods We studied 215 patients with heart failure with left ventricular ejection fraction (LVEF) ≤35%, and New York Heart Association (NYHA) classes II–III who were randomized to either...
