Background: Improvement in left ventricular (LV) function after revascularization is an important determinant of long-term prognosis in a patient with acute myocardial infarction (AMI). However, data on the changes of LV function after revascularization are scarce in our population. Hence, this study was conducted to evaluate the changes in LV function and dimensions by echocardiography at 3 and 6 months after primary percutaneous coronary intervention (PCI). Materials and Methods: A total of 188 patients were recruited in this study who had undergone primary PCI. Patients with preexistent LV dysfunction, prior PCI, or with congenital heart disease were excluded. Echocardiography was performed at baseline (within 24 h of intervention), 3 months, and 6 months of intervention. Remodeling in terms of change in LV ejection fraction (LVEF), LV end-diastolic dimension (LVEDD), LV end-systolic dimension, and wall motion score index (WMSI) was evaluated. Results: Out of the 188 patients, 90.4% were male, and mean age was 53.94 ± 9.12 years. Baseline mean LVEF was 39.79 ± 6.2% with mean improvement of 5.11 ± 3.87 (P < 0.001) at 3 months and 6.38 ± 4.29 (P < 0.001) at 6 months. Baseline LVEDD was 46.23 ± 3.86 mm which improved to 44.68 ± 2.81 mm at 6 months. Basal WMSI decreased by -0.09 ± 0.08 and -0.13 ± 0.09 at 3 and 6 months, respectively, after revascularization. Conclusions: Primary PCI is the recommended mode of reperfusion in patients with AMI. It reduces infarct size, maintains microvascular integrity and preserves LV systolic function hence improving LV function.
