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。
Abstract
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.
