Study Summary

Clopidogrel is the P2Y12 inhibitor of choice in PCI patients requiring OAC. However, concerns have been raised based on the notion that a considerable number of patients may have inadequate response to clopidogrel. Although practice recommendations indicate that the use of potent P2Y12 inhibitors (i.e., ticagrelor) may be considered in patients at increased thrombotic risk, they do not recommend routine testing to identify patients with poor response to clopidogrel. The aim of this study is to assess the pharmacodynamic effects of different P2Y12 inhibiting therapy (clopidogrel vs ticagrelor) in patients at high risk for high platelet reactivity identified according to the ABCD-GENE score in PCI treated patients also requiring OAC. Up to a total of up to 63 patients are planned to be prospectively enrolled in this investigation which will entail a series of comprehensive pharmacodynamic assessments to reach the study aim.

Primary Outcome

The primary end point of our study will be levels of platelet reactivity, measured as P2Y12 reaction units (PRU) using the VerifyNow system of ticagrelor versus clopidogrel in patients with an ABCD-Gene score ≥10. A PRU \>208 suggests high platelet reactivity, while \<85 may indicate increased bleeding risk.
