摘　　要：目的应用血管回声跟踪(ET)技术研究动脉粥样硬化患者动脉弹性的改变及其与动脉硬化程度的关系。方法研究对象分为正常对照组(A组)、动脉硬化无症状组(B组)和动脉硬化有症状组(C组)。应用ET技术检测各组颈动脉、股动脉的血管弹性指标,包括弹性系数(Ep)、僵硬度(β)、顺应性(AC)。结果颈动脉:Ep值和β值,C组大于B组,B组大于A组;AC值,C组小于A组,差异均有显著性。股动脉:Ep值,C组大于B组,B组大于A组;β值,C组大于A组;AC值:C组小于A组,差异均有显著性。在B组和C组中,动脉斑块数量越多,动脉弹性减退程度越重。结论动脉粥样硬化患者动脉弹性减退,动脉粥样硬化的程度越重,动脉弹性减退程度越重。应用血管回声跟踪技术检测动脉弹性,可为动脉粥样硬化的诊断提供有价值的定量指标。Objective Applying echo tracking （ET）technique to study the change of arterial elasticity and the relationship between degree of atherosclerosis and change of arterial elasticity in the patients of atherosclerosis. Methods Studying objects was divided into the group of normal control （ A group） ,the group of atherosclerosis and absence symptoms （ B group） , and the group of atherosclerosis and presence symptoms （C group）. Applying ET technique to detect the index of arterial elasticity of the carotis and femoral artery in each groups. The index included elasticity modulus （ Ep）, stiffness parameter（β） and arterial compliance （AC）. Results In carotis, the Ep and β values of C group were high than of B group, and thoes B group was higher than of A group ; and the AC value of C group was lower than of A group. All the variances weresignificant. In femoral artery, the Ep value of C group was higher than of B group,the β value of C group was larger than A group, the AC value of C group was smaller than A group. All the variances are significant. In B group and C group, the more quantity of arterial plaque is, the more severe decrescence of arterial elasticity. Conclusion The arterial elasticity of patients of atherosclerosis is decrescence. In them,the more severe atherosclerosis,the more severe decrescence of arterial elasticity is. The detection of arterial elasticity with ET technique is valuable for assessing the degree of atherosclerosis.
