摘　　要：目的:探讨颈动脉超声预测冠心病的应用价值。方法:对114例冠状动脉造影检查的患者行颈动脉超声检查,测量内中膜厚度(IMT)以及观察粥样斑块发生率情况。根据冠状动脉造影结果分为冠心病及非冠心病组。结果:对照组及冠心病组IMT值分别为(0.67±0.10)mm及(0.85±0.26)mm,斑块发生率为10%(4/40)及63.5%(47/74),组间相比差别均具有显著性,P<0.001,以IMT≥0.85mm及/或出现粥样斑块来预测冠心病,特异性85%,敏感性71.6%,阳性预测率89.8%。结论:颈动脉与冠状动脉粥样硬化之间有着密切关系,通过颈动脉超声检查可预测冠心病的存在。Objective： To study the applied value of carotid ultrasonography in predication of coronary heart disease. Methods： Carotid ultrasonography was performed in 114 patients had been identified coronary disease by coronary angiography. The carotid index as carotid artery intima -media thickness （IMT） and atherosclerotic plaques were measured by carotid ultrasonography in the control group and coronary disease group. Results： The IMT in the control group and coronary disease group were （0.67 ±0.10）mm and 0.85 ±0.26mm, the prevalence rate of athemsclemtic plaques were 10% （4/40） and 63.5% （47/74） respectively. There was significant difference （P 〈0. 001 ） between the two groups. An IMT≥0.85mm and/or the occurrence of athemsclemtic plaques could predict the presence of coronary disease with a specify of 85% ,a sensitivity of 71.6% and a positive predictive value of 89. 8%. Conclutions： Carotid uhrasonography could predict the presence of coronary heart disease according to the changes of carotid artery intima -media thickness （IMT） and athemsclemtic plaques.
