Effect of puerarin on myocardial perfusion and ventricular wall motion in patients with acute coronary syndrome

Objective To investigate the effects of puerarin(Pur)on myocardial perfusion and ventricular wall motion in patients withacute coronary syndrome(ACS).Methods Thirty-seven patients with ACS were randomly divided into two groups:conventionaltreatment group(n=17,11 males,range of age:32-80 years,average age:60.9±4.9 years)and Purtreatment group(n=20,12 males,rangeof age:40-76 years.average age:62.7±3.5 years).Patients in the conventional treatment group received standard treatment according tothe current guidelines,while patients in the Pur treatment group received intravenous administration of Pur(500 mg/day)for 10 daysplus conventional treatment.Real-time myocardial contrast echocardiography (RT-MCE) was performed to evaluate the change inmyocardial perfusion index (MPI)and veiltricular wall motion index(VWMI)at admission and 10 days after treatment.Results At10 days after treatment,MPI was significantly higher(P＜0.01)and VWMI significantly lower(P＜0.01)in the Pur group comparingwith those in the conventional group.Conclusions Puerarin might improve myocardial microcirculation perfusion and ventricularwall motion in patients with ACS.
