冠脉内支架术后再狭窄与冠心病危险因素的关系

目的: 针对冠状动脉内支架术后再狭窄与非再狭窄病例冠心病危险因素差异进行探讨.方法:1999年2月至2000年12月间我院心内科完成的冠脉内支架术242例患者,对其中60例单支病变患者进行24～36个月随访,据随访结果分为再狭窄组和非再狭窄组,将两组性别、年龄、高血压、高脂血症病史、吸烟史进行比较分析.结果:60例单支病变患者,失访4例,随访率93.3%.再狭窄9例(16.1%).两组间性别、年龄、高血压、高脂血症各因素均无明显差别.再狭窄组合并糖尿病病例数显著多于非再狭窄组.结论糖尿病可作为冠脉内支架植入术后再狭窄的强预测因子.

The Relation Between Restenosis after Intracoronary Stenting and Risk Factor of Coronary Heard Disease.

Objective:To investigate and discuss the differences in risk factors between the cases of restenosis and the cases of non-restenosis after intracoronary stenting.Methods: From Feb 1999 to Apr 2000, there were total 242 intracoronary stenting surgeries in our hospital. Among them, 60 cases of single branch strictuere had been given a follow-up from 24 months to 36 months.According to the results of the follow-up, they were divided into restenosis group and non-restenosis group. Sex, age, hypertension, history of high blood fat and history of smoking were compared between the two groups. Results:4 cases dropped off(drop-off rate 6.7%).9 cases had restenosis(16.1%).There is no significant difference between the two groups about sex, age, hypertension, history of high blood fat and history of smoking, but diabetes cases in restenosis group were far more than those in non-restenosis group. Conclusion: Diabetes may be a powerful predicating factor for restenosis after intracoronary stenting.
