【Objective】To investigate the therapeutic effect of Qiangxin Prescription(QP)on rabbits with heart failure induced by volume overload.【Methods】Twenty New Zealand male rabbits were randomized into four groups:the control group,QP group(QP 2.6?g/kg),western medicine group(Digoxin 20??g/kg and furosemide 1mg/kg)and QP+western medicine group(QP 2.6?g/kg,Digoxin 20??g/kg and furosemide 1?mg/kg).Rabbit models with heart failure induced by volume overload were established.Six hours after the modeling,the treatment groups were given the corresponding drugs according to the experimental design,the treatment lasting 7 days.Four-channel physiologic instrument was used to examine the heart rate(HR),aortic systolic blood pressure(SBP),aortic diastolic blood pressure(DBP),left ventricular systolic pressure(LVSP),left ventricular diastolic pressure(LVDP),the maximum rate of left ventricular pressure rise(+dp/dt_(max)),the maximum rate of left ventricular pressure decrease(-dp/dt_(max))and the maximum rate of left ventricular pressure change(?dp/dt_(max)).Meanwhile,the serum contents of superoxide dismustase(SOD)and malondialdehyde(MDA)were detected.【Results】The difference was insignificant in the body weight in different groups after the modeling but the body weight in western medicine group was decreased one week after medication(P
