Abstract： Objective： To observe the clinical effect of Qishen Yiqi dropping pills combined with western medicine for coronary heart disease(CHD) complicated with chronic heart failure(CHF). Methods：A total of 92 cases of CHD complicated with CHF patients with qi deficiency and blood stasis syndrome were randomly divided into the observation group and the control group，47 and 45 cases in each group respectively. Both groups were given the oral administration of spironolactone tablets，captopril tablets，bisoprolol fumarate tablets，atorvastatin calcium tablets and aspirin enteric- coated tablets；the observation group was additionally given Qishen Yiqi dropping pills. Both groups were treated for three months. Before and after treatment，the 6-minute walk test(6MWT) was conducted；Lee's heart failure score and the score of qi deficiency and blood stasis syndrome were scored；relevant examination by cardiac Color Doppler ultrasound was conducted；the indexes of ultrasonic cardiogram including left ventricular ejection fraction(LVEF)，the ratio of early diastolic peak velocity to advanced diastolic peak velocity in mitral valve(E/A)，stroke volume(SV) and cardiac output(CO) were recorded. The clinical effect and the heart function were compared between the two groups. Results：After treatment，the clinical effect in the observation group was better than that in the control group(P＜0.05)，and the heart function was better than that in the control group(P＜ 0.05). When compared with those before treatment， the 6- minute walk distances in the two groups were increased(P＜ 0.01)，and Lee's heart failure scores and the scores of qi deficiency and blood stasis syndrome were decreased(P＜0.01). The 6- minute walk distance in the observation group was more than that in the control group(P＜0.01)，and Lee's heart failure score and the score of qi deficiency and blood stasis syndrome were lower than those in the control group(P＜0.01). The indexes of LVEF，SV，CO and E/A in the two groups were increased when compared with those before treatment(P＜0.05)， and the four indexes in the observation group were higher than those in the control group(P＜0.05). Conclusion：Based on routine western medicine，the additional application of Qishen Yiqi dropping pills in treating CHD complicated with CHF，can more effectively improve the heart function of patients，reduce the degree of heart failure，and increase their activities，with definite clinical effect.
