血管回声跟踪技术对2型糖尿病患者颈动脉弹性功能的定量检测

Quantitative evaluation of carotid elasticity in type 2 diabetic patients by ET technique

目的探讨E-tracking(ET)技术对2型糖尿病患者颈动脉弹性功能的定量检测。方法应用ET技术检测26例2型糖尿病患者及150例正常人的颈动脉弹性指标β、Eρ、AC、AI及PWVβ。26例2型糖尿病患者中,有11例合并高血压和/或终末期肾病,15例不合并。采用SAS6.12统计分析软件比较糖尿病不合并及合并高血压和/或终末期肾病组与正常人颈动脉弹性的差异。结果单纯2型糖尿病患者组仅AI有差异,而合并高血压和/或终末期肾病患者组的β、Eρ、AI及PWVβ均有差异。结论单纯糖尿病患者颈动脉弹性功能仅AI升高,而合并其他疾病者颈动脉弹性功能全面降低;ET技术能够较敏感地定量检测颈动脉弹性功能。

Objective To detect the carotid elasticity quantitatively in type 2 diabetic （DM）patients by E-tracking （ET） technique. Methods The stiffness parameter （β）, pressure-strain elasticity modulus （Eρ）, arterial compliance （AC）, argumentation index （AI） and one-point pulse wave velocity （PWVβ） of carotid in 26 cases DM patients and 150 cases health adults were calculated automatically by ET technique. Among 26 DM patients,11 cases had complication and 15 cases hadn＇t. The parameters of DM patients and health adults were analyzed using SAS 6.12 statistic software. Results Compared with the health adult, AI was different in DM patients without complication, while all of β, Eρ, AI and PWVβ were different in those DM patients with complication. Conclusion The data was only decreased with AI in DM patients without complication,while decreased with all of β, Eρ, AI and PWVβ in those DM patients withcomplication. This difference can be detected by ET technique.
