efficAcy and Safety of Home-baSed Cardiac rehabIlitation in ChineSe Revascularized patienTs (ASSIST)

A Perspective Randomized Controlled Clinical Trial to Investigate the Effect of Home-based Cardiac Rehabilitation Monitored by Mobile Phone Interaction on Exercise Capacity and One-year Clinical Outcome in Chinese Revascularized Patients

Home-based CR (HBCR) was reported to improve the clinical outcomes of coronary artery disease (CAD) patients. There is no data published to investigate whether HBCR is also effective for Chinese CAD patients who have been revascularized. This trial was designed to investigate the safety and efficacy of CR program at home for Chinese patients who underwent PCI (Percutaneous Coronary Intervention) procedure. This is a multicenter, randomized, controlled and observational study.

Numerous studies have revealed that cardiac rehabilitation (CR) after myocardial Cardiac rehabilitation (CR) after revascularization results in better clinical outcomes, and have been strongly recommended for patients with coronary artery disease. In China, as compared to the exponential increase of PCI (Percutaneous Coronary Intervention) volume, only a very small amount of hospitals are able to develop CR programs. There is no large-scale study to explore the feasible CR pattern either. Home-based CR might be more favorable and practical for so many Chinese revascularized coronary artery disease (CAD) patients due to its feasibility and flexibility as well as low medical cost. This trial was designed to investigate the safety and efficacy of CR program at home for Chinese patients who underwent PCI procedure. This is a multicenter, randomized, controlled and observational study. The efficacy and safety of Home-based CR (HBCR) in revascularized patients will be evaluated through observation of its clinical characteristics and safety indicators. The study will involve 14 sites nationwide, with an expected sample size of 2,000 followed up for 12 months. The primary endpoints is the incidence of composite major adverse cardiac and cerebrovascular events (MACCE,death from any cause, nonfatal myocardial infarction, revascularization, stroke).Secondary endpoints are defined as decrease of hospitalization due to refractory angina pectoris，the improvements of cardiorespiratory fitness,life quality,as well as angina pectoris. The subjects will be randomized into 2 different groups, HBCR group and control group. After comprehensive evaluation, the orders from CR staff will be given. Besides the routine health education in both groups, the subjects in HBCR group will be further introduced the instructions of exercise training. The effect of HBCR on cardiorespiratory fitness, improvement of angina, cardiac function, quality of life, levels of anxiety and depression, as well as risk factor profile will also be evaluated. The investigators also aim to explore the factors which influence the adherence of subjects to our HBCR program.

The exercise training includes aerobic exercise (fast walking or cycling ,30-40 minutes per day,5-6 times a week), stretching exercise (15 minutes every time, 5-6 times a week), and resistance and balance training (each of 15 minutes every time, twice to 3 times a week).
