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.
