摘　　要：目的探讨E-Tracking技术检测2型糖尿病(T2DM)患者颈动脉弹性的应用价值。方法根据颈动脉超声的检查结果,将62例T2DM患者分为两组:A组(颈动脉内中膜增厚和/或斑块存在,32例),B组(颈动脉内中膜无增厚亦无斑块存在,30例)。另选35例正常人作为对照组(C组)。用E-Tracking技术自动跟踪颈总动脉壁的运动,检测收缩期颈总动脉管径(Ds)、舒张期颈总动脉管径(Dd)、压力-应变弹性系数(Ep)、硬化参数(β)、及顺应性(AC)、脉搏波传导速度(PWVβ)和增大指数(AI)。结果A组和B组患者的Ep,β,PWVβ,AI较C组显著增加,AC较C组显著减低。与B组比较,A组的Ep,PWVβ显著增高,AC显著减低。另外,A组和B组患者的Ds和Dd较C组显著增宽。结论在颈动脉出现内中膜增厚或斑块之前,T2DM患者动脉弹性已经发生了变化。E-Tracking技术可用来检查动脉粥样硬化早期的动脉弹性改变。Objective To explore the value of E-Tracking technology in evaluating the elasticity of the carotid artery in type 2 diabetes mellitus （T2DM） patients. Methods A total of 62 cases of T2DM patients were divided into two groups according to the results of B-mode ultrasonography of the carotid artery： group A （with intima-media thickness increasing and/or with plaques of the carotid artery, 32 cases） and group B （without intima-media thickness increasing and plaques of the carotid artery, 30 cases）; and 35 cases of normal subjects were selected as group C （control group）. E-Tracking technology was used to follow the movement tracks of the common carotid arterial wall, and the following parameters were assessed respectively： systolic diameter of common carotid artery （Ds）, diastolic diameter of common carotid artery （Dd）, pressure-strain elastic modulus （Ep）, stiffness parameter （β）, arterial compliance （AC）, pulse wave conducting velocity （PWVβ） and augment index （AI）. Results The parameters of Ep, β, PWVβ, AI in group A and group B were all significantly higher than those of group C, and AC was significantly lower than that of group C. Compared with group B, the parameters of Ep, PWVβ in group A were all significantly higher, and AC was significantly lower. Both Ds and Dd were significantly wider in group A and group B than those of in group C. Conclusion The elasticity of the carotid artery in T2DM patients has changed before the existing of intima-media thickness increasing or plaques. E-Tracking technology can be used to detect the early elasticity changes of arteriosclerosis.
