摘要
目的:探讨回声跟踪(E-Tracking)技术评价吸烟者动脉血管内皮功能的应用价值。方法:筛选113例不同烟龄的吸烟者及50例体检正常的非吸烟者,应用高频超声E-Tracking技术实时跟踪描记双侧颈总动脉,双侧肱动脉管壁随心动周期的运动轨迹,测量血管收缩期内径(Ds)、舒张期内径(Dd)、弹性系数(Eρ)、硬化值(β)和顺应性(AC)。结果:Ds和Dd:吸烟各组与非吸烟组组间无显著性差异(P>0.05);Eρ和β:吸烟各组均高于非吸烟组,差异具有显著性(P<0.05);吸烟各组组间比较差异具有显著性(P<0.01);AC:吸烟各组显著低于非吸烟组,差异具有显著性(P<0.05);吸烟各组组间比较差异具有显著性(P<0.01)。结论:回声跟踪技术可早期发现血管内皮功能的改变,是一种简便、实用的方法。
Objective： To explore the value of E-Tracking technology in evaluating vascular endothelial function in smokers. Methods： One hundred and thirteen of smokers were invested with different smoking period and 50 normal persons with corresponding ages were examined as controls. E-Tracking technology was performed to follow the movement tracks of the common carotid and humerus arterial wall, the following parameters were assessed： internal systolic diameter（Ds）, internal diastolic diameter（Dd）, elastic coefficient（Eρ）, stiffness parameter（β） and compliance（AC）. Results： There were no significant differences of Ds and Dd between smokers and control group（P〉0.05）, Eρ and β were higher in smokers than those in the control group（P〈0.05）. There were significant differences in the three different smoking age groups（P〈0.01）. AC： were lower in smokers than those in the control group（P〈0.05）. There were significant differences in the three groups of smokers（P〈0.01）. Conclusions： E-Tracking technology can be used to access the endothelial dysfunction of smokers, and it is a convenient, practical method.
