Objective To observe the therapeutic effect of Yiqi Jianxin Decoction（decoction for reinforcing qi to promote functions of heart） on patients with peripartum cardiomyopathy（PPCM）.Methods Seventy patients were randomly divided into 2 groups

35 in each.The control group was administered standard western medical therapy

and the treated group was administered both Yiqi Jianxin Decoction and western medicine.Symptoms

signs and heart function before and after treatment were observed for comparison.Results In the treated group

the improvement of clinical symptoms and signs

such as chest distress

palpitation

asthmatic breathing

fatigue and arrhythmia

and parameters of heart function about cardiac output（CO）

stroke volume（SV）

cardiac index（CI）

left ventricular eject fraction（EF） and gradation of heart function was significantly superior to that in the control group（P<0.05）.The total effective rate in the treated group and control group was 94.29% and 77.14% respectively with a significant difference（P<0.01）.Conclusion The effect of Yiqi Jianxin Decoction on PPCM is suppurior to that of routine western medical therapy.
