Background: Coronary Artery Bypass Grafting (CABG) surgery is a common treatment for coronary artery disease, but postoperative recovery can be challenging. Physical activity has been shown to improve outcomes in various cardiac populations, but its impact on postoperative recovery in CABG patients remains unclear.Objective: To investigate the impact of physical activity on postoperative recovery in CABG patients, focusing on functional capacity, quality of life, and cardiovascular parameters.Methods: This randomized controlled trial included 100 CABG patients, randomized into an Exercise Group (n=50) and a Control Group (n=50). The Exercise Group participated in a supervised exercise program post-surgery, while the Control Group received standard care. Functional capacity was assessed using the Six Minute Walk Test, quality of life using the Patient Health Questionnaire-9, and cardiovascular parameters including blood pressure, heart rate, cardiac output, ejection fraction, and rate-pressure product were measured at baseline, 1 week, 1 month, and 3 months post-surgery. Data were analyzed using appropriate statistical methods.
