Abstract Background: Primary percutaneous coronary intervention (PCI) as a type of coronary reperfusion therapy may lead to recanalization and improved myocardial reperfusion in patients with ST elevation myocardial infarction (STEMI). In ST-segment elevation myocardial infarction (STEMI), QRS score and fragmented QRS at presentation ECG may reflect the progression of infarction and facilitate prediction of lv function and micro vascular-reperfusion. Objectives: to investigate the association between fQRS, QRS score, micro vascular-reperfusion and changes in LV function, and to assess the clinical prognostic significance of fQRS and QRS score in patients with STEMI following primary PCI. Patients and Methods: This study has been enrolled between January 2018 &January 2019 studying patients with acute MI who were admitted to national heart institute. We recruited 100 patients with acute myocardial infarction, they were 72males, 28 females (mean age 52.5 ± 10.1 y, range 28 to 70y). The patient were divided into two equal groups based on the presence or absence of fQRS and high or low QRS score following ECG assessment on admission. Following primary PCI and follow up, patients were divided into four groups based on the following: new onset, resolution, persistence or absence of fQRS. The baseline demographic and angiographic characteristics, complications, laboratory and physical examination data on hospitalization were recorded |
