Abstract
Risk stratification of ambulatory heart failure (HF) patients has consistently relied upon peak VO2 (pVO2)<14 ml/kg/min. We investigated whether additional risk factors might further specify the risk of death, LVAD implantation (INTERMACS<4) and heart transplantation (HTx; Status 1A or 1B) within the first year after HTx evaluation. We hypothesized that right ventricular stroke work index (RVSWI), pulmonary capillary wedge pressure (PCWP) and the MELD-Albumin score would be additive prognostic predictors.
