目的：探讨血管回声跟踪（ET）技术在酒精性心肌损害患者颈总动脉弹性评价中的应用。方法选择40例正常对照人群作为A组（对照组），67例酒精性心肌损害患者根据饮酒量分为3组：B组（20例，少量饮酒组），C组（25例，中等量饮酒组），D组（22例，大量饮酒组）。比较各组间应用ET技术获得的颈动脉弹性参数包括压力应变弹性系数（Ep）、僵硬度（β）、顺应性（AC）、增大指数（AI）和脉冲波传导速度（PWVβ）。结果B、C、D组Ep、β、PWVβ值较A组高，AC值较A组低，差异有统计学意义（P＜0.05）。随着饮酒量的不断增加，Ep、β、PWVβ值增加明显，差异有统计学意义（P＜0.05）。AI值各组间差异无统计学意义（P＞0.05）。结论ET技术能准确评价酒精性心肌损害患者颈总动脉的弹性变化。

Objective To explore the application of echo tracking (ET) technique in evaluating the carotid artery elasticity of patients with alcohol-induced myocardial damage. Methods 40 normal control members were chosen as group A (control group). According to drinking amount, 67 patients with alcohol-induced myocardial damage were divided into group B composed of 20 modicum-drink patients, group C composed of 25 moderate-drink patients and group D composed of 22 heavy-drink patients. Carotid artery elasticity parameters obtained by ET technique including Ep (pressure strain elastic modulus),β(stiffness parameter), AC (arterial compliance), AI (augment index) and PWVβ(pulse wave conducting velocity) of different groups were comparatively analyzed. Results The values of Ep,β, PWVβof group B, C, D were signiifcantly higher than those of group A while the values of AC of group B, C, D were signiifcantly lower than those of group A (P<0.05). With the increase of drinking amount, the values of Ep,β, PWVβalso increased signiifcantly (P<0.05). There was no signiifcant difference between all the groups in the value of AI (P>0.05). Conclusion The changes of carotid artery elasticity of patients with alcohol-induced myocardial damage can be detected accurately with ET technique.
