Effect of GPIa C807T and G873A gene polymorphisms on platelet aggregation inhibition rate
Objective:To explore the effect of GPIa C807T and G873A gene polymorphisms on platelet aggregation inhibition rate,aiming to provide experimental data for clinical individualized anti-platelet aggregation therapy.Methods:A total of 80 inpatients receiving antiplatelet treatment with as-pirin were collected and divided into two groups according to the inhibition rate of platelet aggregation detected by thromboelastography.10 patients were divided into the aspirin resistance (AR)group and 70 patients into the aspirin sensitive (AS)group.The genotypes of GPIa C807T,G873A and their al-lele distribution in the two groups were analyzed,and the relationship between clinical data and experi-mental indicators of the two groups were also analyzed.Results:The 807T and 873G alleles in the AR group were higher than those in the AS group (x2=4.039,4.354,P=0.044,0.037).The preva-lence of hypertension and stroke history in the AR group was higher than that in the AS group (x2=4.612,4.737,P=0.032,0.030).Plasma D-dimer (D-D)and serum triglyceride (TG)in the AR group were higher than those in the AS group (t=2.499,2.276,P=0.016,0.033),while platelet aggregation inhibition rate (IPA)and serum glucose (GLU)in the AR group were lower than those in the AS group (t=15.352,3.076,P<0.001,0.005 ).Conclusion:GPIa C807T and G873A gene polymorphism were correlated with aspirin resistance.Joint detection of the two gene loci polymorphisms and platelet aggregation inhibition rate was recommended to jointly guide the clinical in-dividualized antiplatelet aggregation therapy.
