Summary

This study evaluates differences in the extent of myocardial necrosis noted by cardiac MRI in patients with ST-elevation myocardial infarction randomized to receive cangrelor during their percutaneous coronary intervention and compares them to patients randomized to not receive cangrelor.

Detailed description

Cangrelor is a direct-acting and reversible intravenously administered platelet inhibitor approved as an adjunct to percutaneous intervention (PCI) for reducing the risk of periprocedural myocardial infarction, repeat coronary revascularization, and stent thrombosis. As it has a quick onset of action (2 minutes) compared to traditional oral platelet inhibitors, cangrelor is emerging as an important new option for use in patients undergoing percutaneous intervention who have not been treated with oral platelet inhibitors. Furthermore, multiple studies have demonstrated that patients with ST-elevation myocardial infarction (STEMI) who undergo emergent PCI do not have optimal platelet inhibition even after administration of a loading dose of traditional oral platelet inhibitors. However, the clinical significance of complete platelet inhibition around the time of PCI is not fully understood. The primary objective is to characterize the utility of immediate platelet inhibition with intravenous cangrelor in patients presenting with an acute STEMI by assessing the extent of infarct size (either enzymatically or by imaging). If the findings are favorable, this may suggest that immediate platelet inhibition is an important part of care in this patient population.

Conditions
