英文摘要

Background Inflammation is a major cause of restenosis after coronary stenting. Intercellular adhesion molecule-1 (ICAM-1) is an important adhesion molecule that plays a key role in the tight adhesion between leukocytes and vascular endothelium. The object of this study was to investigate the association between the K469E polymorphism of the ICAM-1 gene and restenosis after coronary stenting in North Chinese population.

Methods The ICAM-1 K469E polymorphism was genotyped using polymerase chain reaction-restriction fragment length polymorphism method in 124 patients who had undergone coronary stenting and coronary angiography at least 3 months earlier. Informaiton on clinical risk factors and procedure-related data was also collected.

Results Of 124 enrolled patients in total, there were 72 cases of in-stent restenosis. The restenosis rate in this population was 58.1%. The frequencies of the three possible genotypes of the ICAM-1 K469E polymorphism were: KK genotype 50.8%, EE genotype 41.9% and EK genotype 41.9%. Among restenosis patients, the frequency of the KK genotype was 58.3% and the frequency of E allele carriers was 41.7%. Among non-restenosis patients, the frequency was significantly different (P=0.049). Using multivariate logistic regression, the difference between the two groups was more apparent. The odds ratio of KK homozygotes vs. E allele carriers was 2.6, with 95% confidence interval 1.2-5.8 (P=0.018). After grading of risk factors, we found that the KK genotype was a stronger predictor of in-stent restenosis in obesity or hyperlipemia patients, with an odds ratio of 9.3 and 3.7, respectively (P < 0.05).

Conclusion In our study population, KK homozygotes of the ICAM-1 codon 469 mutation had a higher risk of restenosis after coronary stenting, especially in the case of obese or hyperlipemia patients.
