老年冠心病冠脉支架内再狭窄相关因素调查

目的了解老年冠心病患者冠状动脉支架内再狭窄的发生情况。方法对冠脉造影资料较全的老年冠心病患者中89例患者，复查冠脉造影，观察其再狭窄情况，分析再狭窄相关因素包括年龄、性别、高血压、糖尿病、高血脂及冠脉病变特点、支架性质。结果多支病变占73．9％。89例复查冠脉造影，发现再狭窄率为23．5％；其中，裸支架组的再狭窄率35．2％明显高于药物洗脱支架组。狭窄与无狭窄患者的年龄和血脂水平差异无统计学意义，而并发糖尿病病例数量、支架长度以及支架数量，差异有统计学意义。结论患糖尿病、支架总长度、多个支架、支架性质为再狭窄的相关因素。

Investigation on relevant factors of coronary in-stent restenosis in elder patients with coronary heart disease

Objective To evaluate the elderly coronary in-stent restenosis risk factors and the incidence of restenosis. Methods Coronary angiography in 143 cases of patients with coronary heart disease were randomly selected, analyzing the characteristics of coronary heart disease, and 89 patients of them were reviewed coronary angiography, restenosis was observed, and the restenosis factors including age, sex, hypertension, diabetes, hyperlipidemia and coronary lesions, stent properties were analyzed. Results Statistical multi-vessel disease in patients with coronary heart disease was 73.9% ,restenosis rate was 23.5%. One narrow and contrast the age of the patients without stenosis and no statistically significant difference between lipids. The number of diabetes cases in the two comparison groups,stent length and stent volume were significant different. One bare stent restenosis rate was significantly higher than the drug-eluting stent group. Conclusion The results showed that diabetes ,stent length,multiple stents, stent restenosis,were the relevant factors of coronary restenosis.
