摘要
目的:探讨冠脉内支架植入术后再狭窄的影响因素。方法:选择随访的冠脉造影资料较全的100例冠脉内支架植入术后患者。依据术后冠脉造影复查结果将其分为无再狭窄组和再狭窄组,比较2组临床危险因素(包括年龄、性别、高血压、糖尿病、高脂血症、吸烟)及靶血管病变特点(如病变部位、病变分型、病变长度、术前狭窄程度、最小管腔直径、病变血管支数),分析支架内再狭窄的影响因素。结果:2组年龄、高血压患病率、糖尿病患病率、高脂血症患病率、病变部位、病变分型、病变血管支数差异无统计学意义。再狭窄组男女比例(396)较无再狭窄组(2926)高(P=0.02);再狭窄组吸烟比例(80%)较无再狭窄组(58.6%)高(P=0.03);再狭窄组术前狭窄程度(94.65%±3.62%)较无再狭窄组(88.81%±3.23%)重(P=0.04);再狭窄组病变长度(23.2±10.8)mm较无再狭窄组的(17.6±11.8)mm长(P=0.04)。结论:年龄、高血压患病率、糖尿病患病率、高脂血症患病率、病变部位、病变分型、病变血管支数对冠脉内支架植入术后再狭窄无关,男性、吸烟、病变长度、术前狭窄程度与其有关。
Aim: To evaluate the influencing factor of restenosis after stent placement in coronary artery. Methods: One hundred patients were collected and divided into the groups of in-sent restenosis and non in-sent restenosis according to the results of coronary angiograms. The clinical risk factor and features of lesions affecting restenosis were analyzed. Results: There were no statistical differences in age and prevalence of hypertension, prevalence of diabetes mellitus, prevalence of hyperlimedia, position of lesion, category of lesion,number of involved branches between the two groups. The ratio of male to femal in the group of restenosis was higher than that of non-restenosis((39GA6FA6) vs (29GA6FA26),P= 0.02). Prevalence of smoking in the group of restenosis was higher than that of non-restenosis (80% vs 58.6%, P=0.03).Narrowing degree of target coronary vessles before the procedures in the group of restenosis was moxe severe than that in the group of non-restenosis((94.65%±3.62%) vs (88.81%±3.23%), P=0.04).The length of target coronary vessles before the procedures in the group of restenosis was more longer than that in the group of non-restenosis(( 23.22±10.77) vs (17.47±11.83), P=0.04).Conclusion: The rate of restenosis is not significantly influenced by age, hypertension, diabetes mellitus, hyperlimedia, position of lesion, category of lesion, number of involved branches. But male, smoking, narrowing degree of target coronary vessles,and the length of target coronary vessles are related to restenosis.
