ABSTRACT
Objective To explore the correlation of the TIAM2 functional gene mutations with the bleeding events in patients with coronary heart disease who undergone PCI and postoperative taken anti-platelet drug clopi-dogrel. Methods One hundred and twenty Chinese Han patients who had undergone PCI and postoperative taken anti-platelet drug clopidogrel were orderly enrolled from Guangdong General Hospital. Followed for 6 months after PCI, PCR sequencing was applied to test TIAM2 promoter region genotyping assay. Results After follow-up six months , 113 cases were remained lost of 7 cases , , including 19 cases with bleeding and 94 cases without bleed-ing; Bleeding risk in patients with diabetes mellitus (OR=3.115) or taking statins (OR=11.539), may be high, but there was no significant difference (P > 0.05); TIAM2 promoter region had three variants (c.3168+3116C>T, c.3168+3261A>G,c.3168+3596A>C), including wild-type, heterozygous, and homozygous. The probability of pa-tients with bleeding were 36.84%, 52.63%and 10.53%, and there is a certain chain of state , but the genotype was not significantly correlated with bleeding events of clopidogrel antiplatelet therapy (P>0.05). Conclusion Clopi-dogrel antiplatelet therapy bleeding events were not significantly correlated with TIAM2 functional gene mutation.
