拟诊冠心病患者540例颈动脉粥样硬化斑块的临床分析

Clinical analysis of carotid atherosclerosis plaque in 540 cases of suspected coronary arterydisease

目的探讨颈动脉粥样硬化斑块与冠心病的临床相关性。方法选择本院心血管内科住院拟诊冠心病患者540例行颈动脉超声检查，所有患者根据冠状动脉造影检查结果分为冠心病（CAD）组420例与对照（CON）组120例。其中冠心病组根据心肌梗死诊断标准进一步分为心肌梗死组及非心肌梗死组。超声检查时记录颈动脉粥样硬化斑块的发生情况，对各组病例的斑块发生率进行统计学分析。结果CAD组的斑块发生率明显高于CON组（P〈0．05）。结论颈动脉粥样硬化斑块的发生与冠心病有明显相关性，可以作为冠心病的一种预测指标。

Objective To investigate the relationship between carotid att^erosclerouc plaques and coronary artery disease（CAD）. Methods Totally 540 patients with suspected coronary artery dis- ease were divided into CAD group and control group according to the results of coronary angiography. The CAD group was further subdivided into MI group and non-MI group. All patients underwent carotid uhra- sound. The incidence rate of plaque was calculated and compared statistically. Results The incidence rate of plaque in CAD group was significantly higher than that in CON group （ P 〈 0.05 ）. Conclu- sions The occurence of carotid atherosclerotic plaques is related with the coronary artery disease, can be used as a predictor of coronary artery disease.
