摘要(Abstract):
目的 为探讨冠状动脉支架再狭窄的预测因素。方法 收集我院行冠状动脉支架术并随访冠脉造影的病例 6 2例 ,按冠脉造影结果分为支架再狭窄组 33例 ,无再狭窄组 2 9例 ,并分别比较两组病人的临床特点、血管病变特征及术后即刻血管并发症。结果 再狭窄组病人合并有糖尿病史比例较无狭窄组明显增多 (30 3%∶6 9% ,P <0 0 5 ) ;再狭窄组前降支及开口病变比例均明显高于无狭窄组 (81 8%∶5 9 4% ,P <0 0 5 ;2 1 7%∶6 3% ,P <0 0 5 )。再狭窄组的长支架 (≥ 30mm)、单支血管多支架及小支架比例均明显高于无再狭窄组 (2 2 7%∶5 0 % ,P <0 0 1;40 5 %∶15 6 % ,P <0 0 5 ;2 7 2 %∶2 5 % ,P <0 0 5 ) ;再狭窄组病人的支架边端残余狭窄≥ 2 0 %的比例明显高于无再狭窄组(2 4 3%∶3 1% ,P <0 0 5 )。结论 冠状动脉支架术病人合并糖尿病史、前降支、开口病变、长支架、单支血管多支架、小支架及术后即刻支架残余狭窄可能是术后再狭窄的预测因素
