Background and aim : Despite significant advances in the treatment of coronary artery disease [CAD], the condition remains the primary cause of morbidity and death globally. 15–20% of individuals with coronary artery disease [CAD] have chronic complete occlusion [CTO] of a coronary artery. The purpose of this study was to examine the usefulness of cardiac MR, TTE, Doppler Echocardiography, and speckle tracking echocardiography in identifying recovery in patients with CTO who benefited from revascularization following successful revascularization. Patients and Methods : Thirty patients with ischemic heart disease and coronary angiography-confirmed chronic complete blockage were included in this prospective, single-center observational research. Patients were exposed to a comprehensive history, current medicines, the angioplasty operation, echocardiography, two-dimensional echocardiography, myocardial strain evaluation, cardiovascular magnetic resonance imaging, and follow-up four months following PCI. Only GLS demonstrated a statistically significant improvement in myocardial recovery performance. Conclusion : CTO-PCI may successfully enhance LV function, as concluded.
