Assessment of left ventricular function by three-dimensional transthoracic echocardiography post left anterior descending artery percutaneous coronary intervention in acute ST segment elevation myocardial infarction patients

Abstract

Background: Coronary artery disease (CAD) is a complex condition driven by multiple pathophysiological processes, evolving over time and manifesting through both acute and chronic clinical spectra. In this study, left ventricular performance was assessed using three-dimensional transthoracic echocardiography (3D-TTE) six months after percutaneous coronary intervention (PCI) to the left anterior descending artery (LAD) in patients who presented with acute ST-segment elevation myocardial infarction (STEMI). Methods: This prospective observational single-center study was done on 100 STEMI patients undergoing LAD revascularization using percutaneous transluminal coronary angioplasty (PTCA). Results: The significant improvement in LV parameters estimated by the Simpson's biplane method shows the positive impact of LAD revascularization on systolic function and cardiac structure statistically significant improvement in EF (p=0.013). A highly significant enhancement in EF was observed, with a statistically significant elevation in the mean value (p
