The Effect of Morning vs Evening Aerobic Exercise Training on Cardiac Remodeling and Function Improvement in Patients After ST Elevation Myocardial Infarction

Condition(s) studied

Investigational drug(s) / intervention(s)

Morning aerobic exercise: Patients were randomly assigned to morning aerobic exercise training for a 12-week outpatient training program that included a combination of warm-up, aerobic, and relaxation exercises three times a week. Each class consists of 10 minutes of warm-up training, 40 minutes of aerobic training and 10 minutes of relaxation training. The intensity of aerobic exercise training will be personalized. According to the guidance of relevant guidelines, the exercise intensity of patients will be determined according to the results of their first cardiopulmonary exercise experiment, and the exercise load will be gradually increased according to the exercise program until the predetermined goal is reached. Patient fatigue levels will be monitored throughout the exercise using the borg scale.

Evening aerobic exercise: Patients were randomly assigned to evening aerobic exercise training for a 12-week outpatient training program that included a combination of warm-up, aerobic, and relaxation exercises three times a week. Each class consists of 10 minutes of warm-up training, 40 minutes of aerobic training and 10 minutes of relaxation training. The intensity of aerobic exercise training will be personalized.

Patient fatigue levels will be monitored throughout the exercise using the borg scale.

Study summary

The aim of the study was to intervene in the Aerobic exercise time of patients with STEMI and to explore the optimal exercise time for STEMI patients

Eligibility

Primary outcome measure(s)

• left ventricle ejection fraction — at baseline，at the sixth week, and after the 12th week of training or follow-up
