Abstract SUMMARY I schemia is the cause of decreased ventricular relaxation and diastolic dysfunction, which followed by reduced systolic function. This sequence of events is the outcome of a chain reaction that starts with metabolic and biochemical changes. A temporary impairment in ventricular relaxation is brought on by ischaemia. Even in cases when there are coronary collaterals present, the majority of patients who have a CTO still have some degree of LV dysfunction. It is a technically complex treatment that is performed in the hope of a functional recovery, which has been found to enhance the possibility of survival. This study found that the LVEF tended to improve at approximately 2 months after percutaneous revascularization in patients with CTO. Echocardiography is assuming a prominent role for evaluating left ventricular function after PCI; it provides substantial information regarding left ventricular remodeling post percutaneous coronary intervention and the associated significant changes in systolic echocardiographic derived indices may affect patients morbidity. The study was carried on 30 patients underwent percutaneous coronary intervention for chronic total occlusion, Full echocardiography study and global longitudinal strain assessment was done for all patients pre, then after 2 months. The mean age is 54.97 ± 7.43 years, and 90 % of the studied group were males, 70% were smokers, 70% were Diabetics and 76.7% were hypertensive. Our study showed significant improvement in LV systolic function after successful PCI during the follow-up (2 months), LVEF P value <0.023 (significant) GLS P value <0.001 (highly significant) |
