ABSTRACT
Coronary heart disease is the leading cause of death in the United States and many developed countries. Percutaneous coronary intervention (PCI) is an important means to treat coronary heart disease. However, PCI can not eliminate the risk factors of coronary heart disease. As an important auxiliary means of PCI, cardiac rehabilitation can significantly slow down the progress of atherosclerosis, reduce cardiovascular events, improve patients′ exercise tolerance and the quality of life of patients. It have been developing vigorously in developed countries and achieved remarkable results. This paper will review the effects of cardiac exercise rehabilitation and the research on cardiac exercise rehabilitation in different clinical stages.
ABSTRACT
Objective To explore the influence of cardiac exercise rehabilitation on cardiac function and quality of life(QOL) in acute myocardial infarction(AMI) after percutaneous coronary intervention (PCI).Methods Totally 190 patients with AMI who was successfully performed by PCI were randomly divided into exercise rehabilitation group (n =95),control group (n =95).Patients in Control group were given medical routine guidance including drug treatment and rehabilitation training.These in exercise rehabilitation group were given exercise rehabilitation intervention inside and outside of hospital and follow-up.The cardiac function,major adverse cardiac events (MACE) after PCI between two groups were compared.The change of QOL evaluated by WHOQOL BREF between two groups at different time was analyzed.Results At 6 months after PCI,the LVESD,LVEDD,LVEF in exercise rehabilitation group were obviously improved than those before discharge,and significantly better than those in control group (P ＜ 0.05).At 3,6 months after PCI,the WHO-QOL-BREF score of each dimension was significantly increased than those before discharge (P ＜ 0.05),and the psychological,social relations dimension scores in exercise rehabilitation group were significantly higher than those in control group (P ＜ 0.05).There was significant different on physical dimension score between two groups at 6 months after PCI (P ＜ 0.05).The incidence of MACE within 30 days in exercise rehabilitation group was 9.5 ％,which was significantly lower than that in control group 20.0％ (P ＜ 0.05).Conclusion Cardiac exercise rehabilitation after PCI for AMI patients can contribute to improve heart function,reduce postoperative MACE,and improve the QOL.
