Abstract: Objective To investigate the effect of long-term cardiac rehabilitation on risk factors with doctor supervision after percutaneous coronary intervention(PCI). Methods One hundred and twelve patients after PCI were divided into the cardiac rehabilitation group(56 cases) and the control group (56 cases). All of the patients were given medication and health education, meanwhile the cardiac rehabilitation group received 4～6 weeks hospitalized cardiac rehabilitation program and one year ambulatory cardiac rehabilitation with doctor supervision. Risk factors were assessed six mouths and twelve mouths after the treatment. Results The risk factors except diastolic blood pressure and body weight index improved more significantly in the cardiac rehabilitation group than in the control group. Clinical event in the cardiac rehabilitation group is lower than in the control group. Conclusion Long-term cardiac rehabilitation with doctor supervision is safe, efficiency and good compliance to improve risk factors of coronary heart disease after PCI except diastolic blood pressure and weight management.
