Revascularization

The treatment of STEMI includes prompt revascularization and medical therapy. Revascularization can be performed by either primary PCI, fibrinolytic therapy (thrombolytic therapy) or surgically. Primary PCI is preferred if available within a reasonable timeframe — that is, a door-to-balloon time of less than 90 minutes.

A ST elevation myocardial infarction (STEMI) most commonly occurs when thrombus formation results in complete occlusion of a major epicardial coronary vessel.
