In patients with ST-elevation myocardial infarction (STEMI) early restoration of blood flow in the culprit coronary artery is essential to reduce infarct size and thereby mortality and morbidity. The recommended method for achieving reperfusion is primary percutaneous coronary intervention (PPCI) (1,2). Early initiation of adjunctive antithrombotic therapy is important to prevent further thrombus formation and to facilitate PPCI.
