and the treatment group treated with Xianhe Qiangxin Pills in addition to the conventional therapy.The course of treatment was 6 months in total.After treatment

the effect on cardiac function

Lee’s heart failure scores

and TCM syndromes scores

left ventricular ejection fraction（LVEF）

maximum systolic blood flow velocity of early diastolic / late diastolic（E/A） ratio and the result of 6 minutes walking time（6MWT） were observed.Results After treatment

the comparison in the total effective rate of cardiac function

Lee’s heart failure scores and TCM syndromes scores

LVEF

（E/A） ratio and 6MWT showed a better effect in the treatment group than in the control group with a significant difference（P<0.05）.The safe indices of both groups showed no changes before and after treatment.Conclusion Xianhe Qiangxin Pills combined with conventional western medicine is more effective in the treatment of heart failure due to coronary heart disease than simple western medicine.
