Abstract
Objectives: Our previous studies identified three single nucleotide polymorphisms (SNPs), rs419598 in the interleukin-1 receptor antagonist gene (IL1RN), rs235326 in the CD18 gene (ITGB2), and rs5918 in the platelet glycoprotein IIIa gene (ITGB3), as risk factors for restenosis after placement of bare metal stents in coronary arteries. The aim of the present study was to determine whether these SNPs remain risk factors after drug-eluting stent implantation. Patients and methods: The study population included 2028 patients, who underwent drug-eluting stent implantation. The primary study endpoint was angiographic restenosis (diameter stenosis ≥50% at the 6-month follow-up angiography) and clinical restenosis (target lesion revascularization at the 3-year follow-up). Results: Angiographic restenosis was observed in 12.8% of the patients with genotype T/T, 14.6% with genotype T/C, and 13.0% with genotype C/C of IL1RN (P=0.60), in 13.1% of the patients with genotype C/C, 13.2% with genotype C/T, and 16.1% with genotype T/T of ITGB2 (P= 0.53), and in 13.2% of the patients with genotype T/T, 14.8% with genotype T/C, and 9.6% with genotype C/C of ITGB3 (P=0.50). Clinical restenosis was present in 11.8% of the patients with genotype T/T, 12.5% with genotype T/C, and 9.9% with genotype C/C of IL1RN (P =0.63), in 13.3% of the patients with genotype C/C, 10.0% with genotype C/T, and 13.9% with genotype T/Tof ITGB2 (P=0.07), and in 11.9% of the patients with genotype T/T, 12.1% with genotype T/C, and 10.2% with genotype C/C of ITGB3 (P=0.91). Conclusion: The SNPs rs419598 in IL1RN, rs235326 in ITGB2, and rs5918 in ITGB3, which have shown an association with restenosis after implantation of bare metal stents, were not related to restenosis after placement of drug-eluting stents.
