Abstract Objective To investigate the factors influencing revascularization in patients underwent coronary artery stent implantation. Methods 544 patients who underwent coronary artery stent implantation received coronary angiography one year later. The clinical data, stent type and coronary lesion features were analyzed. Logistic regression analysis was performed to determine influencing factors of revascularization. Results Non- target lesion revascularization was performed in 91 cases, target lesion revascularization in 53 cases, both target and non target lesion revascularization in 3 cases, and no revascularization in 397 cases. The proportions of paclitaxel eluting stent (32.1% vs 11.8%, P<0.01) and true bifurcation lesion (18.9% vs 6.5%, P<0.01) were significantly higher in target lesion revascularization group. Logistic regression analysis confirmed that Paclitaxel eluting stent (OR 3.78,95 %CI 1.94~ 7.35, P<0.01) and true bifurcation lesion (OR 3.73, 95% CI 1.64~ 8.47, P<0.01) were influencing factors of target lesion revascularization and old myocardial infarction(OR 1.916, 95%CI 1.02~3.61, P<0.05) was influencing factor of non- target lesion revascularization. Conclusion Paclitaxel eluting stent and true bifurcation lesion are relevant to target lesion revascularization. Old myocardial infarction is relevant to non- target lesion revascularization.
