摘要： 目的 应用血管回声跟踪技术(ET)评价饮酒者颈总动脉弹性。方法 将141 例研究对象分成不饮酒组35例、少量饮酒组35例、中量饮酒组35例、大量饮酒组36例，所有研究对象除外高血压、高血脂、糖尿病以及严重心脏、脑、肾，甲状腺等疾病，而且颈总动脉无斑块形成。应用血管回声跟踪技术（E-tracking technology,ET）实时跟踪描记受检者双侧颈总动脉管壁运动轨迹，计算分析得出僵硬度（β）、压力-应变弹性系数（Eρ）、血管顺应性（AC）、脉搏波传导速度（PWVβ），对各组所得参数进行统计学分析，以此评估饮酒对颈总动脉弹性的影响。 结果 各组间进行参数比较：随着饮酒量的增加，β、Ep、PWVβ参数值逐渐增高，AC值逐渐降低；大量饮酒组、中量饮酒组与不饮酒各参数（β、Ep、AC及PWVβ）测值比较有统计学意义（P<0.05）；大量饮酒组、中量饮酒组与少量饮酒组比较有统计学意义（P<0.05）；大量饮酒组与中量饮酒组比较有统计学意义（P<0.05）。少量饮酒组与不饮酒组比较无统计学意义（P>0.05）。结论 大量饮酒、中量饮酒可引起颈总动脉弹性减退,ET技术可早期发现颈总动脉弹性的改变。

Abstract: Objective To explore the value of E-tracking technology ( ET) in evaluating carotid artery elasticity in drinker . Methods One hundred and forty one subjects were enrolled in the study and grouped to 35 ones of non-drink group,35 ones of modicum-drink group,35 ones of moderate-drink group and 36 ones of heavy-drink group,that all of the subjects exclude high bloodpressure,hyperlipidemia,diabetes and serious heart、brain、kidney、hypothyroid disease,carotid arteries have no plaque. Application of E-tracking technology torack real-time polygraph subjects bilateral common carotidarter wall movement, Calculatedanalysis of stiffness parameter(β), epressure-strain elastic coefficient (Eρ),arterial compliance(AC),one-point pulse wave velocity calculate from β (PWVβ), and carry on statistics analysis to various parameters to assess carotid artery elasticity change of drinker. Results Comparison parameter among all groups:with the increase in alcohol consumption,stiffness parameter(β), elasticity modulus(Eρ),one point pulsewave velocity calculated from β value(PWVβ) values gradually increased,arterial compliance(AC)decreased; heavy-drink group、moderate-drink group and non-drink group values in each parameter between groups showed with significant difference(P<0.05)；heavy-drink group、moderate-drink group compare with modicum-drink group,the statistical test with significant difference(P<0.05); the heavy-drink group compare with moderate-drink group,the statistical test with significant difference(P<0.05); modicum-drink group compare with non-drink group with no significant difference(P>0.05),there is no statistical significance. Conclusion Heavy-drink、modicum-drink can bring the decrease of carotid arterial elasticity ,ET technique can early detection the change of carotid artery elasticity .
