Relation of Pre-transplant Peak Oxygen Consumption to Outcomes after Heart Transplantation

ABSTRACT Peak exercise oxygen consumption (pVO2) is an important predictor of prognosis in patients with heart failure (HF). The association between pre-transplant pVO2 and post-transplantation outcomes in HF patients has not been previously studied. We identified adult OHT recipients with available pVO2 in the United Network for Organ Sharing (UNOS) registry (2000-2015). Patients were divided in 3 categories using Weber classification: class B (pVO2 16-20 ml/kg/min), class C (pVO2 10-16 ml/kg/min), and class D (pVO2 14 days) hospitalization (adjusted OR 1.42 [1.20-1.68], P
