Improvement of Functional Capacity and Quality of Life by Cardiac Rehabilitation: Case Series

Cardiac rehabilitation (CR) is a long-term program involving prescribed exercise, education, and counseling to mitigate the physiological and psychological impacts of cardiac disease. Despite evidence supporting its effectiveness in reducing mortality rates, CR remains underutilized, particularly among patients with heart failure. This research aims to highlight the importance of CR in improving the quality of life and functional capacity for post-cardiac surgery and heart failure patients. The study involved a series of case illustrations, including patients undergoing aortic valve replacement, coronary artery bypass graft surgery, and congenital heart disease repair. Each patient completed a Phase II rehabilitation program consisting of 12 exercise sessions, with functional capacity measured using the six-minute walk test (6MWT). The results indicated significant improvements in both functional capacity and quality of life, including reductions in depression levels. The findings suggest that CR is highly beneficial in enhancing patients' overall recovery and quality of life, particularly when integrated into standard postoperative care. Given these results, healthcare systems should promote broader access to CR programs to maximize patient outcomes. Additionally, future research should explore long-term benefits and develop personalized CR programs to cater to diverse patient needs.
