Evaluation of the effect of elective percutaneous intervention to left coronary artery disease on left ventricular functions: an echocardiography and tissue Doppler study

Abstract

Background and Aim Coronary artery disease (CAD) is the leading cause of death worldwide. After acute myocardial infarction (AMI), CAD is a serious and common ailment that can influence a patient’s prognosis and quality of life. Aim of the study The aim of this study was to assess the effect of elective percutaneous coronary intervention (PCI) on left ventricular (LV) functions after 3 months in patient with significant chronic left coronary system lesions by echo and tissue doppler imaging (TDI). Patients and methods The study was conducted on 30 patients with chronic significant (more than 70%) left coronary system stenosis as proved by diagnostic coronary angiography with or without other coronary artery affections. Resuts Left ventricular ejection fraction (EF) was statistically significant different between the patient’s pre-& post-PCI (mean ± SD was = 0.4893 ± 0.06963 pre-PCI, 0.4550 ± 0.05158 post-PCI with P value of 0.0341. twenty two of patients (73.3%) were males and 8 (26.7%) were females, with age ranged from 40 to 67 years and mean age or 55.92 years. Conclusion PCI for a significant coronary lesion has a beneficial effect on LV functions, improvement in regional and global LV functions & myocardial contractility after revascularization that can be predicted by conventional echo and TDI.
