Peak VO2 ≤14 ml/kg/min was associated with higher mortality in stable HF; extends prognostic evidence but leaves transplant timing thresholds open.
Does an exercise peak VO2 ≤14 ml/kg/min predict worse prognosis in patients with stable chronic heart failure?
An exercise peak VO2 threshold of 14 ml/kg/min is a strong independent prognostic factor for death and major events in stable chronic heart failure patients, useful for determining optimal timing for cardiac transplantation.
