目的：探讨冠状动脉支架植入术后支架内再狭窄发生的危险因素。方法：选取本院2011年2月-2012年2月实行的冠状动脉支架植入术后施行冠状动脉造影的患者98例作为研究的对象，并对其临床资料进行回顾性分析。使用Logistic多因素对其进行逐步的分析。结果：分析表明再狭窄的发生和患者吸烟与否、是否患有糖尿病、在进行第二次的冠脉介入治疗之前LDL-C的水平有关系，即正相关，与之相对应的危险度是12.45、11.45及5.62，同时与支架是否为药物涂层成负相关，其危险度为0.02。结论：糖尿病患者在进行手术之后极其容易发生支架术后再狭窄的症状，为避免或减少该症状，可以使用药物支架。对LDL-C的水平进行控制并戒烟是支架植入术后患者避免支架内再狭窄的关键性因素。%Objective:To explore the risk factors of coronary artery stent restenosis after stent implantation.Method:98 cases of patients who accepted coronary arteriongraphy after coronary artery stent implantation from February 2011 to February 2012 were selected as the subjects.And the clinical data were retrospectively analyzed and used logistic multifactor analysis step by step.Result:The analysis showed that the occurrence of restenosis was related to the smoking status,whether suffering from diabetes,and the level of LDL-C before a second percutaneous coronary intervention.And the corresponding risk was 12.45、11.45 and 5.62,at the same time whether stents for drug-coated negative correlation,the risk was 0.02.Conclusion:The symptoms of restenosis diabetic patients is extremely easy to occur after sent implantation.In order to avoid or reduce the symptoms,we can use the stents. The key factor to avoid stent restenosis after stent implantation is to control the levels of LDL-C and quit smoking.
