1. To assess the effect of high-intensity interval training on peak metabolic equivalents in patients with coronary heart disease after the coronary artery bypass grafting surgery. 2. To assess the effect of a home-based cardiac rehabilitation program on peak metabolic equivalents in patients with coronary heart disease after coronary artery bypass grafting surgery. 3. To compare functional outcomes between the different treatment approaches.
Participants will be eligible if they are clinically stable as defined by the American College of Cardiology/American Heart Association.
Only Participants will be stratified as low to moderate risk as identified by the American College of Sport Medicine/
Mean age ± standard deviation, 55 ± 3 years.
All patients underwent coronary artery bypass graft surgery, rested at home for at least one month, and then returned to the center for a cardiac rehabilitation program
Patients will be excluded from this study if they had an ejection fraction of less than 40% at rest (high risk as defined by American Association of Cardiovascular and Pulmonary Rehabilitation Stratification).
Mental health disorders (such an anxiety or depression).
Any vision or hearing defects or any neurological, respiratory, or musculoskeletal conditions that have an impact on ambulation.
Irreversible heart failure.
