Angioplasty as early revascularization in acute myocardial infarction.

The clinical manifestations characterized by myocardial ischemia due to a sudden decrease in coronary artery flow are defined as "acute coronary syndromes". These syndromes are classified according to the presence of ST segment elevation on the electrocardiogram (ECG) and the presence of a Q wave. In ST-elevation myocardial infarction (STEMI), the lesion is usually located at the proximal part and the coronary occlusion is complete, myocardial loss is to a great extent, prognosis is poor, and the risk of developing cardiac failure and arrhythmias in the post infarction period is high. Considering these complications, it is obvious that the immediate provision of reperfusion by opening the completely occluded artery is of vital importance in patients with STEMI. However, a third of these patients are unable to receive reperfusion therapy on time A considerable number of patients can receive the treatment within 12 hours after the onset of symptoms at best. In cases arriving late, the effectiveness of reperfusion therapy decreases and the risk of mortality and morbidity increases.
