Objective:To observe the clinical efficacy of enhanced external counterpulsation(EECP)on community patients with coronary heart disease.Methods:80 patients who were referred back to the community for rehabilitation treatment after treatment in the superior hospital were selected to participate in the study,and were divided into control group and treatment group according to dif-ferent rehabilitation methods,with 40 cases in each group.The control group was given drug combined with routine rehabilitation exer-cise therapy,while the treatment group was treated with EECP rehabilitation therapy on this basis.The differences in cardiac reserve in-dexes,pulmonary reserve indexes and exercise tolerance indexes before and after treatment and differences in quality of life(MLHFQ score)and sleep quality(PSQI score)before treatment and after 1,2 and 3 months of treatment were compared between the two groups.Results:After treatment,the levels of cardiopulmonary reserve indexes and exercise tolerance indexes in both groups were signif-icantly improved compared with those before treatment(P＜0.05),and the left ventricular ejection fraction(LVEF),stroke volume(SV),pulmonary reserve indexes and exercise tolerance indexes in treatment group improved more significantly compared to control group(P＜0.05).After 1,2,and 3 months of treatment,the MLHFQ score and PSQI score were decreased in both groups of patients(P＜0.05),and the scores in treatment group at each time point were lower than those in control group(P＜0.05).Conclusion:EE-CP can effectively improve the cardiopulmonary function and exercise tolerance,enhance the quality of life and sleep quality in commu-nity patients with coronary heart disease,and is worthy of promotion and application.
