The Effect of HIIT, MICT in Patients With Myocardial Infarction

Status Recruiting

Clinical Trial Summary

This study will investigate the effect of a 12-weeks cardiac rehabilitation training (HIIT, MICT) program on VO2peak and cardiac fibrosis in patients, and evaluate the effects of HIIT on endothelial function, microvascular obstruction, body fat, inflammation, arrhythmia and psychology .

Clinical Trial Description

Eligible and consenting patients are randomized (block randomization) in a 1:1:1 ratio. According to the number of 180 samples calculated by the sample size, the random number table containing 1-180 ( including shedding cases ) was obtained by the computer. Case number will be assigned to participants in each group according to the order of grouping, and each case number corresponded to Group1(HIIT), 2(MICT) or 3(Control) according to the random number. The HIIT sessions include brief, intermittent bouts of high-intensity exercise interspersed with periods of low-intensity exercise (active recovery). HIIT include 20 intervals of high-intensity (30-60s at rating of perceived exertion (RPE; Borg scale of 6-20) of 15 to 17) and low-intensity (1min at RPE <10 or totally rest). The whole exercise cycle takes around 40-50 minutes (Figure 2). In MICT Group, patients perform 40-50 minutes at a RPE of 12 to 14(a total of 4 groups, each group 5-8 min, interspersed with 2-minute rest)(Figure 3). HIIT and MICT are performed only during supervised sessions with non-consecutive 3 days/week. And all patients are supervised by professional CR team. After assessing by therapists and doctors, participants also can perform three days of home-based exercises guided by wearing a sports bracelet. The CR program includes 36 sessions supervised exercises, pharmacological counseling, patient education, catering management, smoking cessation counseling, stress management, and psychological counseling. A standard 36 sessions of CR usually lasts 12 weeks (three sessions per week). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
