The Heart Failure Survival Score outperforms the peak oxygen consumption for heart transplantation selection in the era of device therapy

The HFSS outperforms the peak VO2 in risk stratification for CHF in the presence of an ICD and/or CRT. Furthermore, a peak VO2 ≤10 ml/kg/min rather than the traditional cutoff value ≤14 ml/min/kg may be more useful for risk stratification in the device era.
