  • Title: The genetic basis of platelet responsiveness to clopidogrel. A critical review of the literature.
    Author: Fefer P, Matetzky S.
    Journal: Thromb Haemost; 2011 Aug; 106(2):203-10. PubMed ID: 21792462.
    Abstract:
    Clopidogrel reduces ischaemic complications in a wide range of patients with coronary artery disease. However, there is much inter-individual variation in clopidogrel-induced platelet inhibition, and a substantial proportion of patients will exhibit non-responsiveness to clopidogrel. Multiple studies have demonstrated an association between the presence of genetic polymorphisms associated with suboptimal clopidogrel-active metabolite generation, decreased platelet responsiveness, and adverse clinical outcomes. However, it is not clear to what extent the genetic polymorphisms account for the observed variability in response to clopidogrel. In this review we provide a critical summary of the available evidence linking genetic factors with response to clopidogrel, and discuss the clinical implications of this association.
