【摘要】 目的探讨冠心病患者支架植入术后1年再次血运重建的影响因素。方法 544例冠状动脉支架植入患者1年后行冠状动脉造影复查,分析临床资料、支架类型及病变特点。采用Logistic回归分析冠状动脉支架术后再次血运重建的影响因素。结果非靶病变血运重建91例,靶病变再次血运重建53例.靶病变与非靶病变同时血运重建3例,非血运重建397例(对照组)。靶病变再次血运重建组紫杉醇支架使用率(32.1%vs11.8%)和真性分叉病变比例(18.9%vs 6.5%)较对照组高(均P<0.01)。Logistic回归分析显示紫杉醇支架(OR3.78,95%CI 1.94~7.35,P<0.01)和真性分叉病变(OR3.73,95%CI1.64~8.47,P<0.01)是影响靶病变再次血运重建因素,而既往心肌梗死病史(OR1.916,95%CI 1.02~3.61,P<0.05)是影响非靶病变再次血运重建的因素。结论紫杉醇支架、真性分叉病变与靶病变再次血运重建有关,既往心肌梗死与非靶病变血运重建有关。更多还原

【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%vs11.8%,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.更多还原
