Stent thrombosis is a morbid complication following percutaneous coronary intervention (PCI). Dual antiplatelet therapy significantly reduces stent thrombosis risk. However, the antiplatelet response to clopidogrel – the most frequently used ADP receptor antagonist in post-PCI patients – varies among individuals. High on-treatment platelet reactivity was repeatedly associated with the risk of stent thrombosis. Ticagrelor is a novel ADP receptor blocker that has shown greater, more rapid and more consistent platelet inhibition than clopidogrel. This agent offers a unique mechanism of action, no relevant pharmacological interactions, consistent platelet inhibition, and a good safety profile. This article reviews the prospective use of ticagrelor in the treatment of stent thrombosis in acute coronary syndrome patients undergoing PCI of culprit coronary lesion.
