title: Platelet function testing and tailored antiplatelet therapy.
abstract: Dual antiplatelet therapy, consisting of aspirin and a P2Y12 receptor inhibitor, has dramatically reduced the incidence of atherothrombotic events for patients with acute coronary syndrome and those undergoing a percutaneous coronary intervention (PCI). However, the platelet inhibitory effect of clopidogrel, the most commonly used P2Y12 inhibitor, is variable between patients. Patients exhibiting high platelet reactivity (HPR) despite clopidogrel treatment are at higher risk of recurrent atherothrombotic events after PCI. In order to reduce the incidence of HPR, the more potent P2Y12 receptor inhibitors prasugrel and ticagrelor are used. However, these drugs increase the risk of bleeding. As there is evidence of a therapeutic window for platelet inhibition, platelet function tests could be helpful for tailoring antiplatelet therapy based on the patient's thrombotic and bleeding risk. In the present article, we review the most commonly used platelet function tests and the current evidence for tailoring of antiplatelet therapy in PCI patients.
