摘　　要：目的探讨血管回声追踪（E-Tracking）技术评价亚临床甲状腺功能减退患者颈动脉血管内皮功能的应用价值。方法38例亚临床甲状腺功能减退患者及60例正常者，应用E—Tracking技术检测双侧颈总动脉弹性模量（Ep）、僵硬度（B）、顺应性（AC）、膨大系数（AI）及脉搏波传导速度（PWVβ）。结果亚临床甲状腺功能减退组Ep、β、AI、PWVβ与正常对照组比较明显升高，AC降低，差异有统计学意义（P〈0．05）。结论亚临床甲状腺功能减退患者易发生早期动脉血管内皮功能损伤，E-Tracking技术有助于早期发现及定量分析。Objective To explore the value of E-Tracking technique in evaluating the vascular endothelial function of carotid artery in subclinical hypothyroidism. Methods The study population include 38 subclinical hypothyroidism patients and 60 normal controls. E-Tracking technique was performed to track the movements of the common carotid artery and the following parameters were assessed： stiffness parameter（β）, elastic coefficient （Ep）, arterial compliance （AC）, augment index （AI） and one point pulse wave velocity （PWVβ）. Results Ep, β, AI and PWVβ were significantly higher in subclinical hypothyroidism than those in the control group,AC were lower than that in the control group（ P 〈0.05）. Conclusions Vascular endothelial function in subclinical hypothyroidism patients is injured in early stage. E- Tracking technique may conduce to find the injury early and may assess it quantitatively.
