Interventions

  • High Intensity Interval Training program — OTHER
    High-Intensity Interval Training (HIIT) includes a 5-minute warm-up, followed by a 3-minute training session at 60% to 70% of heart rate reserve and four 4-minute high-intensity intervals at 80% to 90% of heart rate reserve. Each interval is followed by a 3-minute active recovery at 60% to 70% of heart rate reserve, concluding with a 4-minute cool-down. Subjects without balance or leg issues performed treadmill exercises, while those with such complaints used a leg ergo-cycle.
  • home-based cardiac rehabilitation intervention — OTHER
    The home-based cardiac rehabilitation program utilizes Physio-tools software for exercise management. Participants will receive a data sheet for exercise logging, a color-coded program, and a Polar watch. Weekly phone support will provide encouragement and answer questions. The program involves moderate-intensity exercises, 3 times a week, including circuit training for 45 minutes, with structured warm-up, aerobic, and cool-down phases.
  • no intervention program — OTHER
    The control group had no intervention program. Based on current standard practice, all participants will be given an instruction booklet that contains instructions and precautions about surgery, wound care and encouragement to be active.

Study Details

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.
