Antecedent Hypertension Interacts with Adverse Ventricular Remodeling after Myocardial Infarction

Background : Ventricular remodeling is an independent predictor of left ventricular function in patients with myocardial infarction (MI). Accelerated ventricular remodeling is a probable contributor to the increased mortality observed after MI in hypertensive patients. The purpose of this study is to assess the relationship of antecedent hypertension to ventricular remodeling after MI. / Methods : Seventy-nine patients presenting with a first acute MI (AMI) who were treated and attained Thrombolysis In Myocardial Infarction (TIMI) flow grade 3 with re-perfusion therapy within 12 hours of their symptom onset were enrolled in this study. All of them underwent left ventriculography (LVG) immediately after re-perfusion therapy and again at 6 months after the occurrence of MI. Patients were divided into two groups; hypertensive group and normotensive group. End-diastolic volume index (EDVI), end-systolic volume index (ESVI), and EF were compared between acute phase and 6 months after AMI in each group....
