Effect of clinical factors and gene polymorphism of CYP2C192, 17 and CYP4F23 on early stent thrombosis

To determine the main clinical and genetic factors having impact on early coronary stent thrombosis. Genotyping of CYP2C19*2, *17 and CYP4F2*3 in patients with (n = 31) and without stent thrombosis (n = 456) was performed. Clinical and genetic data were analyzed by binary logistic regression. Smoking (OR: 0.317; 95% CI: 0.131-0.767), high-density lipoprotein level in mmol/l (OR: 0.142; 95% CI: 0.040-0.506), CYP2C19*2*2 versus *1*1 and *1*2 genotype (OR: 11.625; 95% CI: 3.498-38.633), CYP4F2 AA versus GA and GG genotype (OR: 3.532; 95% CI: 1.153-10.822) were associated with early stent thrombosis. For the first time we have identified a clinically important polymorphism (CYP4F2 G1347A) that was independently associated with early stent thrombosis.
