摘要
目的探讨冠状动脉无保护左主干（UPLM）病变的临床特征。方法选取2011年4月至2014年8月行冠脉造影确诊为左主干病变的患者120例，根据病情严重程度分为急性心肌梗死组（AMI）22例和不稳定型心绞痛组（UAP）98例，比较两组间基线资料、冠状动脉病变特征、支架置入情况。结果AMI组与UAP组间年龄、性别、高血压病史、糖尿病史、吸烟史比较差异未见统计学意义（P〉0．05），AMI组高脂血症比例明显高于UAP组，差异有统计学意义（P〈0．05）。两组间左主干病变部位、合并其他病变分布比较差异未见统计学意义（P〉0．05）。两组间经皮冠状动脉介入术（PCI）术中所使用的支架直径、预扩球囊直径及长度、后扩球囊直径及长度比较差异未见统计学意义（P〉0．05），支架长度比较差异有统计学意义（P〈0．05）。结论在UPLM病变中AMI患者的高脂血症发生率较UAP患者高，AMI组PCI术所用支架长度较UAP组长，有利于评估患者的病情严重程度及选择合适的支架及术式。
Objective To investigate the clinical characteristics of patients with unprotected left main（UPLM） coronary artery disease. Methods One hundred and twenty patients with UPLM coronary artery disease were devided into acute myocardial infarction （AMI） group and unstable angina pectoris （UAP） group. The baseline information, coronary artery lesion characteristics and stent placement were compared between different groups. Results No significant difference was found between the two groups in age, gender, hypertention, diabetes mellitus or smoking history （P 〉 0.05）. The patients in AMI group had higher incidence rate of hyperlipemia （ P 〈 0.05 ）. There were no significant differences between the two groups in the left main and other branch coronary arteries lesion location （ P 〉 0. 05 ）, as it in the stent diameter, pre-expanding balloon diameter and length, post-expanding balloon diameter and length. The stent length in AMI group was significantly longer than that in the UAP group { P 〈 0. 05 ）. Conclusions The incidence rate of hyperlipemia is higher in AMI group than that in UAP group, and the stent used in PCI is longer in AMI group than that in UAP group. These may help to estimate the severity of UPLM coronary artery disease and to choose suitable stent size and operating methods.
