Preoperative nutritional status is associated with progression of postoperative cardiac rehabilitation in patients undergoing cardiovascular surgery

Objective Preoperative frailty affects the progression of cardiac rehabilitation (CR) after cardiovascular surgery. Different frailty assessment measures are available. However, it remains unclear which tool most likely predicts the progress of CR. Our aim was to evaluate preoperative frailty using different methods and to identify the predictors in the progress of postoperative CR.
