文档介绍：冠状动脉内支架再狭窄的多因素回归分析2010-12-15郭静萱毛节明郭丽君张福春李海燕温尚煜赵一鸣陈明哲【摘要】目的分析与冠状动脉内支架再狭窄有关的临床和血管造影及其处理因素。方法回顾性分析了在我院成功冠状动脉内支架置入和6个月后有冠状动脉造影随访的74例病人的临床和血管造影及处理资料。用单因素和多因素回归分析方法分析了病人年龄、冠心病易患因素、靶病变形态学、及术后最小管腔开放直径(MLD)等32个变量与再狭窄的关系。结果在单因素分析中发现:术前血管参照直径和术后MLD在再狭窄组明显低于非再狭窄组(±±±±(P<)。(%%,P<)。多元Logistic回归分析发现:术后支架管腔MLD、支架直径<、吸烟和高龄是再狭窄的独立危险因素。结论术后支架管腔MLD、支架直径<、吸烟和高龄是最重要的支架再狭窄的独立危险因素。【关键词】冠状动脉疾病支架再狭窄Multivariateanalysisofpost-stentingcoronaryrestenosisGuoJingxuan,MaoJieming,GuoLijun,,BeijingMedicalUniversity,Beijing100083 【Abstract】 Objective Tostudytherelationshipbetweenpost-stentingcoronaryrestenosisanditsrelevantclinical, essfullyunderwentcoronarystentimplantationandsix-monthangiographicfollow-′sage,riskfactorsforcoronaryheartdisease,haracteristicsoftargetlesionsandpostproceduralminimalluminaldiameter(MLD), Univariateanalysisrevealedthatthereference-vesseldiameterandpost-stentingMLDintherestenosisgroupweresignificantlysmallerthaninthenon-restenosisgroup(±±,P<±±<,respectively).Therestenosisratewashigherinthesubs
