摘　　要：目的:研究颈动脉彩色超声检查与冠状动脉病变相关性。方法:回顾本院同期进行颈动脉彩色超声及冠状动脉造影检查的患者140例。根据造影结果分为冠心病单支病变组、多支病变组和冠状动脉正常组(对照组),比较各组颈动脉内中膜厚度和斑块发生率,及对冠状动脉疾病的预测意义,并观察颈动脉斑块发生率与冠状动脉造影阳性率之间的意义。结果:冠状动脉病变组的颈动脉内膜厚度比对照组有增厚;颈动脉斑块发生率明显高于对照组,并随冠状动脉病变支数增加,颈动脉内膜厚度和斑块发生率随之增高。颈动脉斑块对预测冠心病的敏感性高于颈动脉内中膜增厚,当同时存在颈动脉斑块和颈动脉内中膜增厚时,预测冠心病的敏感性及特异性和阳性预测值进一步升高,分别为85.71%、95.24%、97.67%。经超声检查有颈动脉斑块患者行冠状动脉造影检查阳性率明显增高。结论:颈动脉彩超检测颈动脉内中膜增厚,斑块形成可提示冠状动脉病变意义,能提高冠状动脉造影检查阳性率。Objective： To research the relationship between color utrasonography on carotid artery results and coronary artery lesions. Methods： 140 patients＇ diagnosing results of carotid artery utrasonography and coronary angiography in the same period were reviewed. According to the coronary angiography results, those patients were divided into coronary artery disease （CAD） single-branch and multi-branches and none-CAD （Control）, compared intima-meclia thickness and carotid artery athermanous plaque occurring rate. Results： Intima-meclia thickness of carotid artery in CAD group were thicker and the carotid artery athermanous plaque occurring rate was higher, the positive predictive value of CAD was 85.71%, 95.24%, 97.67%. Conclusion： Carotid artery atherosclerosis is highly related with coronary artery lesions, color ultrasonography on carotid artery can be useful in coronary artery lesions＂ early diagnosis.
