Abstract: Objective  To explore the efficacy of home cardiac rehabilitation exercise in patients with coronary heart disease(CHD) after percutaneous coronary intervention(PCI).Methods  According to the order of admission,92 patients with CHD who were received PCI in the third grade hospital and lived in our community were divided into control group(46 cases) and observation group(46 cases).Patients in control group were received conventional treatment after PCI,and patietns in observation group were received home cardiac rehabilitation exercise on basis of those in control group within 3 months.BMI,heart rate,blood pressure,left ventricular end diastolic diameter(LVEDD),left ventricular ejection fraction(LVEF),6 min walking distance and metabolic equivalent (METs) were compared between the two groups.The Seattle angina questionnaire(SAQ) was used to assess quality of life of patietns in the two groups before and after treatment and the results were compared.Results  There were no significant differences of BMI,heart rate,blood pressure,LVEDD,LVEF,6 minutes walking distance,METs and score of every item in SAQ between patient of the two groups before treatment(P＞0.05).BMI,diastolic blood pressure and LVEDD after treatment in patients of observation group were lower than those before treatment,LVEF,6 minutes walking distance,METs and score of every item in SAQ were higher than those before treatment(P＜0.05).LVEDD after treatment in patients of control group was lower than that before treatment,scores of angina stability,treatment satisfaction and disease recognition in SAQ were higher than those before treatment(P＜0.05).Diastolic blood pressure after treatment in patients of observation group was lower than that of control group,LVEF,6 minutes walking distance,METs and score of every item in SAQ were higher than those of control group(P＜0.05).Conclusion  Home cardiac rehabilitation exercise can reduce BMI in patients with CHD after PCI,regulate their blood pressure,improve cardiac function,improve exercise tolerance and quality of life.
