目的 分析老年冠心病合并糖尿病患者置入药物洗脱支架(DES)后2年内非计划的再次血运重建的发生率和预测因素.方法 入选2010年12月～2013年12月在北京安贞医院成功置入DES的老年冠心病合并糖尿病患者2764例,分为再次血运重建组(重建组)383例和非再次血运重建组(非重建组)2381例.采用多因素Cox回归分析.结果 2年内,共有383例(13.9％)患者发生再次血运重建.与非重建组比较,重建组胰岛素治疗比例更高、糖尿病病程更长(P＜0.05,P＜0.01).多因素Cox回归分析显示,胰岛素治疗、冠状动脉旁路移植术史、糖化血红蛋白水平、LDL-C水平、多支冠状动脉介入治疗和随访时未使用他汀类药物是再次血运重建的独立预测因素.再次血运重建与随后再次心肌梗死的有关(调整HR=3.967,95％CI:1.284～6.254,P=0.017),与全因死亡无关(调整HR=6.134,95％CI:0.435～26.224,P=0.154).结论 患者疾病的严重程度、复杂的冠状动脉操作和不充分的药物治疗增加再次血运重建的风险.再次血运重建与随后的缺血性心血管事件有关.%Objective To analyze the incidence and predictors of unplanned repeat revascularization (RR) in CHD patients with DM within 2 years after coronary drug-eluting stent (DES) implantation.Methods A total of 2764 CHD patients with DM who underwent successful DES were divided into RR group (n=383) and non-RR group (n=2381).The effect of RR on all-cause mortality and myocardial infarction (MI) was analyzed by Cox regression analysis.Results Unplanned RR was detected in 383 patients (13.9％) within 2 years after DES.The rate of insulin therapy for DM was higher and the duration of DM was longer in RR group than in non-RR group (P＜0.05,P＜0.01).Multivariate Cox regression analysis showed that insulin therapy for DM,history of coronary artery bypass graft,serum HbAlc and LDL-C level,multivessel PCI and no use of statins during the follow-up period were the independent predictors of RR.RR was related with MI (adjusted HR=3.967,95％CI:1.284-6.254,P=0.017) but not related with all-cause mortality (adjusted HR=6.134,95％CI:0.435-26.224,P=0.154).Conclusion The severity of disease,complex coronary artery procedures and insufficient drug therapy are the risk factors for RR,and RR is related with ischemic cardiovascular events.
