Abstract:
The aim of this study was to investigate factors contributing to left ventricular dysfunction (LVD) in patients who had survived acute myocardial infarction(AMI). Retrospective regression analysis was performed for all the hospitalized patients with AMI who underwent coronary angiography from 1988 to 1998. 155 patients met the entry criteria. Seven patients(4 5%) died of cardiac events after discharge during the ten years′ follow up. In the multivariate logistic regression analysis and stepwise selection, the following factors appeared to be the significantly independent predictors of the LVD after AMI : age, hypertension, hyperlipidemia, LVEF during the first admission, size of infarction, the number of vessel disease, thrombolytic therapy, PTCA. In the COX regression and stepwise selection, the following factors appeared to be significantly independent predictors of the LVD after AMI : hyperlipidemia, LVED during the first admission, size of infarction, the number of vessel disease, thrombolytic therapy , PTCA. The probability of LVD increased with time. Patients with advanced age, hypertension, hyperlipidemia, large infarction, multivessel disease, reduced LVEF after AMI, no thrombolysis and PTCA are prone to develop LVD.
