Abstract
Abstract Background STEMI is the most serious presentation of atherosclerotic CAD carrying the most hazardous consequences. STEMI is caused by occlusion of a major coronary artery and primary PCI is the recommended reperfusion therapy over fibrinolysis if performed by an experienced team as soon as possible. Myocardial infarction makes significant changes in composition, shape, and contractile function of myocardium. Especially left ventricle which is the major contributor to the contractile function of the heart, so it affects the systolic and diastolic functions of the heart. Objective To study the dynamic changes of left ventricular global longitudinal strain and diastolic function parameters in patients undergoing primary percutaneous coronary intervention with TIMI flow grade III after anterior STEMI Methods This study is a prospective observational study that was conducted at Ain Shams university hospitals, in the time interval from October 2022 till June 2023. A total of 100 Patients with anterior STEMI Results Our study showed significant improvement in LV systolic function, GLS and diastolic function parameters after PCI during the follow-up. Age > 53, DM, Chest pain to door > 7 hours and CK-total > 4356 were associated with no GLS recovery in Univariate analysis. In multivariate analysis, Chest pain to door > 7 hours was independently associated with no GLS recovery at follow-up with a sensitivity 90 % and specificity 95%. Conclusion In the present study we found Our study showed significant improvement in LV systolic function, GLS and diastolic function parameters after PCI during the follow-up. Age > 53, DM, Chest pain to door > 7 hours and CK-total > 4356 were associated with no GLS recovery in Univariate analysis. In multivariate analysis, Chest pain to door > 7 hours was independently associated with no GLS recovery at follow-up with a sensitivity 90 % and specificity 95%.
