ABSTRACT
ObjectiveToinvestigatethecorrelationofaspirinresistance(AR),genepolymorphismof platelet membrane glycoprotein (GP)Ⅱb HPA-3 and recurrent ischemic stroke. Methods The consecutive patients w ith acute ischemic stroke and gender, age-matched healthy subjects w ere enrol ed. Adenosine diphosphate (ADP) and arachidonic acid (AA) w ere used as inducing agents. The platelet aggregation rate (PAgT) was detected by flow cytometry. AR was defined as PAgTADP≥39.27% and PAgTAA≥34.27%. Polymerase chain reaction-restriction fragment length polymorphism w as used to detect the GPⅡbHPA-3 genotype. Results A total of 224 patients w ith acute ischemic stroke (case group) and 98 healthy subjects (control group) were enroled. In the case group, 162 patients had the first-ever stroke (first-ever stroke group) and 62 had recurrent stroke (recurrent stroke group). The incidence of AR in the case group w as 15.18%, in w hich the incidence of AR in the recurrent group w as significantly higher than that in the first-ever stroke group (27.42%vs.10.49%; χ2 =9.977, P=0.002). The frequencies of bb genotype ( P=0.004) and b alele (P=0.001) in the recurrent group were significantly higher than those in the first-ever stroke group. In the case group, the frequencies of bb genotype ( P=0.028) and b alele (P=0.004) in the AR group w ere significantly higher than those in the non-AR group. Multivariable logistic regression analysis show ed that AR (odds ratio [OR] 2.933, 95%confidence interval [CI] 1.326-6.486;P=0.008) and bb genotype (OR 2.198, 95%CI1.164-4.149, P=0.015) w ere the independent risk factors for recurrent ischemic stroke. Conclusions AR and GP Ⅱb HPA-3 bb genotype are associated w ith recurrent ischemic stroke.
