Cardiopulmonary exercise performance of cancer survivors and patients with stable coronary artery disease with preserved ejection fraction compared to healthy controls

Purpose: Cardiorespiratory fitness (CRF) is a predictor of lower mortality in patients with coronary artery disease (CAD) and cancer patients. Whether cancer survivors with preserved ejection fraction (EF) have a higher fitness level than patients with stable CAD and heart failure with preserved EF (HFpEF) is unknown.Methods: We enrolled 61 cancer survivors with an EF >50% (mean age 56.9 years ± 12.4), 60 patients with HFpEF and stable CAD (mean...
