    摘要:

    目的 分析血管回声跟踪技术在老年冠心病患者动脉弹性评价中的应用价值。方法 收集老年冠心病患者108例作为冠心病组,健康志愿者50例作为非冠心病组。冠心病组又根据冠状动脉造影结果分为单支病变组47例,多支病变组61例。采用血管回声跟踪技术对所有受试者的动脉弹性评价指标压力应变弹性系数(Ep)、硬化度(β)、单点脉搏波速度(PWVβ)和动脉顺应性(AC)进行测定,并比较组间差异。结果 冠心病组颈动脉弹性参数Ep、β、PWVβ均显著大于非冠心病组(P<0.05),冠心病患者中多支病变组颈动脉弹性参数Ep、β、PWVβ均显著大于冠心病患者中单支病变组(P<0.05);各组间AC均无明显差异。结论 颈动脉弹性参数Ep、β、PWVβ与冠心病的发生、发展密切相关,血管回声跟踪技术是评价冠心病的有效技术手段。

    Abstract:

    Aim To evaluate the values of applying echo-tracking technique in aged patients with coronary heart disease (CHD). Methods We enrolled 108 aged patients with CHD as the CHD group. Fifty healthy volunteers were enrolled as the control group. CHD patients were classified into two groups according to the findings of coronary angiography: one-vessel lesion group (47 cases) and multi-vessel lesion group (61 cases). For all subjects, indexes of arterial elasticity including pressure-strain elasticity modulus (Ep), wall stiffness index (β), one-point pulse wave velocity (PWVβ) and arterial compliance (AC) were measured with echo-tracking, and then compared among study groups. Results The Ep, β, PWVβ of carotid artery in CHD group were significantly greater than that in the control group (P<0.05). The Ep, β, PWVβ in multi-vessel lesion group were significantly greater than that in one-vessel lesion group (P<0.05). There was no difference of AC among various groups. Conclusions Indexes of carotid artery elasticity including Ep, β, PWVβ were closely associated with the occurrence and development of CHD. Echo-tracking can be an effective technique for the evaluation of CHD.
