dc.description.abstractPolymorphisms in the CYP2C9 gene may be associated with adverse vascular events following endovascular procedures independent of antiplatelet therapy. We aimed to investigate the impact of CYP2C9 loss-of-function polymorphisms on adverse vascular events following neurointervention. Consecutive patients undergoing neurointervention were prospectively recruited between 2010 and 2016. Patients were genotyped for the CYP2C9*2 and *3 loss-of-function polymorphisms. On the basis of possible genetic influence on antiplatelet response, ex vivo clopidogrel response was measured using the VerifyNow® P2Y12 Assay. The primary endpoint was the 90-day incidence of adverse vascular events including ischemic stroke. A total of 229 patients were included. The median age was 57 years (IQR: 49-64), and 158 (69.00%) were female. Eighty-one (35.37%) patients carried at least one CYP2C9 loss-of-function (LOF) allele. After adjustment for stroke risk factors, the 90-day incidence of ischemic stroke was significantly lower in the LOF group compared to the wild type group (1.23% vs 10.14%; ORadj = 0.16, 95% CI: 0.03-0.91; p = 0.04). Our results suggest protection against ischemic stroke in carriers of CYP2C9*2 or *3 polymorphisms undergoing neurointervention. Our findings warrant further studies to investigate the mechanisms by which CYP2C9 may influence the risk of ischemic stroke.-
