Echocardiography derived variables predicting left ventricular remodeling after acute myocardial infarction

Objective: This study was to investigate the value of Echocardiographic measurements in predicting Left Ventricular Remodeling （LVRM） after Acute Myocardial Infarction （AMI）. Methods: 52 patients with first AMI underwent echo examinations at day 5 1±1 9 and 10 6±3 4 months after AMI. Results: During the follow up, left ventricular end diastolic diameter （LVD）, left ventricular end diastolic volume index（EDVI）,systolic volume index （SVI） and Doppler derived mitral deceleration time （DT） increased significantly （P＜0. 05） There were 37 LVRM in 52 AMI patients In a stepwise regression model,both SVI,DT emerged as the independent predictor of LVRM A significant inverse correlation was found between SVI and changes in EDVI （ΔEDVI）,the same to DT The regression equation was ΔEDVI=49 55-0 95SVI-0 13DT, R²=0 50（P＜0. 01）. Conclusion: Among the echocardiography variances, SVI and DT provide independent predictors of LVRM for patients with AMI.
