THE ROLE OF PRIMARY PERCUTANEOUS CORONARY INTERVENTION IN THE MANAGEMENT OF ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION

Abstract

Background: ST-segment elevation myocardial infarction (STEMI) is a cardiovascular emergency resulting from total coronary artery occlusion that requires immediate reperfusion to reduce mortality and the extent of myocardial damage. Primary percutaneous coronary intervention (primary PCI) has become the primary reperfusion strategy due to its greater effectiveness and safety compared to fibrinolysis. Case : STEMI patients typically present with typical chest pain accompanied by ECG changes in the form of ST -segment elevation, indicating transmural m yocardial ischemia. After the diagnosis is confirmed, patients are immediately referred for primary PCI with a target optimal reperfusion time. This procedure allows for the opening of blocked coronary arteries as well as direct evaluation of coronary anatomy. Results : Rapid and precise primary PCI achieved TIMI 3 coronary flow, reduced reinfarction and bleeding complications, and improved left ventricular function. Short - and long- term clinical outcomes demonstrated decreased mortality and improved patien t quality of life.
