摘要：目的：探讨超声心动仪检测颈动脉结构及功能改变与冠状动脉病变及其严重程度之间相关关系。方法：87例住院患者，根据冠脉造影(CAG)结果分为冠脉单支病变组(A组)、多支病变组(B组)，CAG阴性者作为对照组(C组)。全部病例采用超声心动仪检测双侧颈动脉内径、斑块情况、内膜—中层厚度(IMT)。结果：颈动脉结构及功能改变与年龄显著相关。冠脉狭窄组的斑块发生率、斑块面积和Cuorse积分均显著高于对照组，且多支病变组明显高于单支病变组，统计学有显著性差异。结论：颈动脉粥样硬化及严重程度对冠心病有较高的预测价值。

    Abstract： Objective： To study the correlativity between the change of carotid construction and function detected with ultrasound cardiotachograph and the various degree of coronary stenosis. Method： Eighty-seven cases who accepted coronary angiography were divided into three groups: mono-vessel disease group(A group), multi-vessel disease group(B group) and normal vessel group(C group) ,C group was control group. Ultrasound cardiotachograph detected the inner diameter, the intima-media thickness (IMT) and the plaque information of carotid artery in all patients. Result： The change of carotid construction and function correlated with age significantly. The incidence rate, areas and the Cuorse score of plaque in coronary stenosis group were much higher than that in control group, and multi-vessel group were obviously higher than mono-vessel group, which have statistically significant difference. Conclusion： It is valuable that through carotid artery atherosclerosis and its severity degree predict coronary artery disease. ......
