Objective: To observe the therapeutic effect of Danshen and Huangqi injection in treatment of chronic heart failure. Method: Eighty-four patients were randomly divided into two groups. The treatment group and the control group were treated with the same routine medicine

while the treated group was additionally treated with Danshen and Huangqi. The clinical efficacy before and after treatment and the changes of color doppler ultrasonic cardiogram examinations were both observed. And walking distance in 6 minutes was detected. Result: The apparent efficiency

the total effective rate and walking distance in 6 minutes in the treated group were remarkably better than that in the control group(P<0.05). The walking distance in 6 minutes and the rate of left ventricle eject fraction (LVEF)

left ventricular end-diastolic volume (LVEDV)

left ventricular end-systolic volume (LVESV)

blood pressure and heart rate of the two groups were obviously improved after treatment (P<0.05). Each indexes in the treatment group were improved more than that of the control group (P<0.05). Conclusion: Danshen and Huangqi injection is an effective and safe treatment with less side effect.
