Abstract:
[Objective]To investigate the relationship between clopidogrel response , early neurological deterioration and CYP2C19 gene polymorphism in sICAS patients.[Methods]116 sICAS patients were divided into deterioration group and non-deterio?ration group by whether appear early nervous function deterioration. Record included the baseline data,the genotypes of CYP2C19, platelet maximum aggregation rate after 7 days of given clopidogrel,CYP2C19 genotype and clopidogrel reaction were compared be?tween two groups.[Results]The deterioration group combination with diabetes ,stroke/TIA were significantly higher than the non-de?terioration group(P<0.05);The frequency of CYP2C19*2 AA genotype and A allele were significantly higher than those in non-dete?rioration group. The frequency of GG genotype were significantly lower than non-deterioration group (27.27% vs 2.13%,50.00% vs 14.84%,27.27% vs 72.34%)(P<0.01);The poor metabolic genotype platelet maximum aggregation rate were significantly higher than that of the fast-metabolic genotype and middle metabolic genotype(P<0.01,P<0.05),Middle metabolic genotype platelet maxi?mum aggregation rate were significantly higher than fast-metabolic genotype(P<0.01);The deterioration group fast-metabolic geno?type were significantly lower than non-deterioration group ,poor metabolic genotype were significantly higher than non-deterioration group(22.73% vs 65.96%,36.36% vs 5.32%)(P<0.01);Clopidogrel resistance rate 59.09% were significantly higher non-deteriora?tion group 28.72%(P<0.05).[Conclusion]Clopidogrel response and early neurological deterioration in sICAS patients is associatedwith CYP2C19 gene polymorphism.
