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。
Objective: To investigate the relationship between the changes of carotid artery structure and function and coronary artery lesions and their severity by echocardiography. Methods: Eighty-seven hospitalized patients were divided into three groups according to coronary angiography (CAG): single coronary artery disease group (group A), multiple vessel disease group (group B), and negative CAG as control group (group C). In all cases, bilateral carotid artery internal diameter, plaque, and intima-media thickness (IMT) were measured by echocardiography. Results: The structure and function of carotid artery were significantly correlated with age. The incidence of plaque, plaque area and Cuorse integral in coronary artery stenosis group were significantly higher than those in control group, and the multi-vessel disease group was significantly higher than that in single vessel disease group with statistically significant differences. Conclusion: Carotid atherosclerosis and severity of coronary heart disease have a higher predictive value.
