Abstract:
Objective:To evaluate the efficacy and safety of intermittent aerobic exercise of different intensities in the cardiac rehabilitation of patients with acute coronary syndrome so as to provide a reference for making the best exercise prescription.Methods:Sixty-four acute coronary syndrome patients were randomly divided into a maximum-intensity and a high-intensity intermittent aerobic exercise group, each of 32. Both groups underwent 2 weeks of adaptive training, followed by 4 weeks of intermittent aerobic exercise (3d/week) at either 95-100% or 85% of their heart rate reserve. The maximum oxygen uptake (VO 2max) was measured before and after the intervention, and any exercise-related adverse reactions were recorded. Results:Both groups completed the 671.6-hour exercise plan without any cardiovascular or musculoskeletal complications. After the intervention, the average VO 2max of the maximum-intensity group had increased by 31.2%, versus 17.2% for the high-intensity group, a significant difference. Conclusion:Maximum-intensity aerobic exercise is more effective than high-intensity in improving cardiopulmonary function among patients with acute coronary syndrome. With strict monitoring, both intensities are safe.
