Abstract

Evidence for cardiac rehabilitation after valve surgery remains scarce. We retrospectively enrolled consecutive patients undergoing aortic valve surgery. The intervention group consisted of physical exercise for 3 months after surgery, while the control group underwent usual care without physical exercise. It was observed that cardiac rehabilitation has a beneficial effect on the peak oxygen uptake compared to the control group (24.2 ml/kg/min vs. 20.6 ml/kg/min) as measured by cardiopulmonary exercise testing 3 months after surgery. There was no significant difference observed in New York Heart Association class I or II between groups. Conversely, the intervention group underperformed the SF-36 Mental Component Scale at 3 months (50.3 vs. 53.8 points).
