冠心病PCI术后再狭窄的临床分析

Analysis of restenosis after percutaneous coronary intervention in patients with coronary heart disease

目的:了解冠心病冠状动脉介入治疗(PCI)术后再狭窄的原因,为预防再狭窄发生提供根据。方法:回顾性分析我院冠脉支架置入300例中冠脉造影随访的74例的临床、血管造影及处理资料。并根据随访结果有、无再狭窄分为再狭窄组(42例),无再狭窄组(32例),分析病人年龄、性别、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)等因素与再狭窄的关系。结果:与无再狭窄组比较,再狭窄组的男性(34.4%比76.2%)、吸烟(46.9%比71.4%)、PCI术后管腔直径<3.5mm(40.0%比62.2%)显著增加。结论:男性、吸烟、支架直径<3.5mm与PCI后冠状动脉再狭窄有关。

Objective：To explore causes of restenosis after percutaneous coronary intervention（PCI） in patients with coronary heart disease（CHD） and provide evidence for prevention of restenosis.Methods：Retrospective analyses were performed on clinical and coronary angiographic data of 74 CHD patients followed up with coronary angiography undergoing PCI in our hospital.According to condition of restenosis,the patients were divided into restenosis group（n=42） and non-restenosis group（n=32）.Analyses were performed on relationship among age,gender,risk factors of CHD,morphology of target lesion,minimal luminal diameter（MLD） after PCI and restenosis.Results：Compared with non-restenosis group,the male（34.4% vs.76.2%）,smoking rate（46.9% vs.71.4%）,stent diameter〈 3.5mm（40.0 vs.62%）in restenosis group significantly increased.Conclusion：Male,smoking,stent diameter〈 3.5 mm are related with coronary restenosis after percutaneous coronary intervention.
