RESUMO
Objective To explore the therapeutic effect of irbesartan treatment on left ventricular remodeing after acute myocardial infarction by 2D Doppler technique.Methods 85 patients with AMI were selected into the study.42 patients were randomized to conventional treatment group,43 patients to irbesartan treatment group.At first week and 26 week after AMI,the left ventricular myocardium weight(LVMW) and diastolic volume(LVDV) were measured by echocardiogram,and the parameters of left ventricular systolic and diastolic function were measured by echocardiogram.Results (1)At 26 week,LVDV and LVMW in irbesartan treatment groups were significantly decreased as compared with conventional treatment group,left ventricular eiection fraction(LVEF) in irbesartan group was increased.(2)PE(peak E-wave velocity) and PFR(peak filling rate) in irbesartan group were increased as compared with conventional group.Conclusion Irbesaratan might significantly reduce myocardial dilatation of left ventricle,decrease LVMW after AMI and improve left ventricle function.
