Abstract:
Objective: To analyze influencing factors of in-stent restenosis after coronary artery stent implantation, to provide theoretical support for clinical prevention of restenosis. Methods: Clinical data of 123 patients, who received coronary artery stent implantation in our hospital from Mar 2011 to Sep 2013 and received coronary angiography follow-up one year after operation, were retrospectively analyzed. In-stent restenosis was regarded as stenosis of inner diameter of implanted stent≥50%, so patients were divided into restenosis group (n=35) and non-restenosis group (n=88). Multi-factor Logistic regression analysis was used to analyze influencing factors of coronary in-stent restenosis. Results: Compared with non-restenosis group, there were significant reductions in serum level of total bilirubin [(14.02±6.76) μmol/L vs. (10.90±4.51) μmol/L] and stent diameter [(3.06±0.86) mm vs. (2.87±0.44) mm] in restenosis group, P<0.01 both. Multi-factor Logistic regression analysis indicated that blood glucose level was independent risk factor for restenosis after coronary artery stent implantation (OR=2.545, P=0.035), while stent diameter and serum level of total bilirubin were its protective factors (OR=0.857, 0.850, P<0.05 both). Conclusion: Blood glucose level is an independent risk factor for restenosis after coronary artery stent implantation, while stent diameter and serum level of total bilirubin are its protective factors.
