To evaluate the effects of the method of purging lung and draining water on heart failure echocardiography index in patients with heart failure induced by coronary heart disease.Methods:A total of 55 patients with heart failure induced by coronary heart disease in our hospital from November 2016 to December 2017 were randomly divided into two groups，the treatment group (30 cases，treated with the routine therapy of western medicine and Xinshuai Mixture) and control group (30 cases，treated with the routine therapy of Western medicine).The course of treatment was 14 days.Before and after the treatment，TCM syndrome integral and the heart failure echocardiography index were tested.Results:After treatment，the TCM symptoms integral of the two groups were significantly improved than before treatment (P<0.05).The improvement in the treatment group was better than the control group (P<0.05).The ventricular diastolic function，left ventricular ejection fraction，pulmonary artery systolic pressure，atrioventricular refactoring and heart failure echocardiography index of the observation group were improved than before treatment (P<0.05).After treatment，the ventricular diastolic function，left ventricular ejection fraction，pulmonary artery systolic pressure and heart failure echocardiography index of the control group were improved than before treatment (P<0.05).After treatment，the valvular regurgitation，pulmonary artery systolic pressure and heart failure echocardiography index of the observation group improved more significantly compared with the control group (P<0.05).Conclusion:On the basis of western medicine convention treatment，the method of purging lung and draining water can effectively improve the TCM symptoms and heart failure echocardiography index in patients with heart failure induced by coronary heart disease.
