Background: Postoperative exercise-based rehabilitation improves the physical performance and health-related outcomes of patients undergoing coronary artery bypass grafting (CABG). However, the effectiveness of exercise-based prehabilitation in patients undergoing CABG remains unknown. Objective: The purpose of this systematic review was to investigate the effects of exercise-based prehabilitation on functional exercise capacity, postoperative complications, anxiety, depression, self-efficacy, quality of life, length of hospital and intensive care unit stay, frailty, and endothelial function in patients undergoing CABG surgery. Methods: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta- Analyses (PRISMA) guidelines. The study protocol is recorded in the PROSPERO database (registration number CRD42023488530). PubMed, the Physiotherapy Evidence Database (PEDro), Google Scholar, Web of Science, Scopus, and the Cochrane Library were searched from inception to December 2023. The titles and abstracts of the studies were screened using Rayyan Ai software. After full-text screening, randomized controlled trials that met the inclusion criteria were included. Results: Five randomized controlled trials involving 616 participants were included. The systematic review suggests strong evidence that exercise-based prehabilitation improved functional capacity and moderate evidence that it reduced postoperative complications and length of hospital stay. Although there was conflicting evidence regarding the effects of exercise-based prehabilitation on quality of life, there was limited evidence of its effects on physical activity, anxiety, depression, self-efficacy, frailty, and endothelial function. Conclusions: Exercise-based prehabilitation can be recommended for improvements in functional capacity, postoperative complications, and length of hospital stay in patients undergoing CABG.
