THROMBOLYSIS IN ST- ELEVATION MYOCARDIALINFRACTION PATIENTS: CLINICAL PREDICTORS OF REPERFUSIONAND ANGIOGRAPHIC OUTCOMES

Background: Thrombolysis is an alternative strategy for reperfusion in the management of ST- Elevation Myocardial Infraction (STEMI) patients, when percutaneous coronary intervention (PCI) cannot be performed. However, using clinical markers of reperfusion, thrombolysis is not always successful for all patients and immediate angiographicrescue PCI is indicated. Aim of the Work: Thegoal of this clinical study was to determinethe angiographic efficacy of thrombolysis in STEMI patients. Besides its correlation in successful or failed thrombolysis (FT) based on clinicalcriteria of reperfusion. Material/Methods: The study population included patients with acute STEMI within 12 hours of onset chest pain, who were admitted to The Cardiac Intensive Care Unit of cardiology department, atUniversityHospital Center Mohammed VI of Marrakech Morocco, receiving thrombolysis with Tenecteplase, during the period from January2021 to January2023. Repeated Electrocardiogram (EKG) at baseline, 90 minutes after Thrombolysis to define FT and PCIwereperformedfor all patients. Results:121 patients with a mean age of 56 years were recruited in the study. Successful thrombolysis was present in 60% of pati
