    Author: Huang YS, Sun JH, Li XZ.
    Journal: Zhongguo Wei Zhong Bing Ji Jiu Yi Xue; 2003 Aug; 15(8):476-8. PubMed ID: 12919649.
    Abstract:
    OBJECTIVE: To compare the inhibitory effects of irbesartan on left ventricular remodeling (LVRM) after acute myocardial infarction (AMI). METHODS: A total of 72 patients with AMI were entered into the study, 36 patients were randomized to conventional treatment group, and 36 patients to irbesartan treatment group. At 2nd week and 24th week after AMI, the left ventricular myocardium weight was measured by echocardiogram, and the parameters of left ventricular systolic and diastolic function were measured by equilibrium radionuclide angiography. RESULTS: At 24th week, interventricular septal thickness (IVST), left ventricular posterior wall thick(LVPWT), left ventricular diastolic diameter (LVDd) and left ventricular mass index(LVMI) in irbesartan treatment group were significantly decreased(P<0.05 or P<0.01) compared with conventional treatment group At 24th week, left ventricular ejection fraction(LVEF), left ventricular peak ejecting rate (LPER) and left ventricular peak filling rate (LPFR) in irbesartan treatment group were significantly increased (P<0.05 or P<0.01) compared with those in conventional treatment group, respectively. Left ventricular time of peak ejecting rate (LTPER) and left ventricular time of peak filling rate (LTPFR) in irbesartan group were decreased(P<0.05 or P<0.01) compared with the conventional treatment group, respectively. CONCLUSION: Irbesartan might significantly reduce myocardial hypertrophy and LVRM after AMI. Irbesartan improves the left ventricular systolic function.
