摘要
目的：应用新版血管壁回声跟踪技术（E-Tracking）评价高血压颈动脉血管病变。方法：分别对高血压患者56例（平均年龄55.5岁）和正常健康者52例（平均年龄54.7岁）采用高频线阵探头测量颈总动脉内中膜厚度（IMT），应用新版血管壁回声跟踪技术检测弹性系数（Eρ）、硬化参数（β）、顺应性（AC）、脉搏波传导速度（PWVβ）和增大指数（AI），并对高血压患者组上述参数进行相关性分析。结果：高血压组较正常对照组Eρ，β，PWVβ及IMT增高，AC降低，且均有显著性差异。高血压组的PWVβ与β，Eρ和IMT呈正相关，与AC呈负相关；高血压组的AI与Eρ，β，AC和IMT无明显相关。结论：新版E-Tracking技术客观准确的反映了高血压患者血管弹性改变，是评价血管壁弹性简便实用的新方法。
Abstract
Objective: A study on vascular pathology of carotid artery in hypertension by newly E-Tracking technology. Methods: A total of 108 cases were divided into two groups: hypertension group(56 cases) and normal group(52 cases). The change of artery function were evaluated by E-Tracking technique. Results: Compared with the normal group, data of Eρ, β, PWVβ and IMT were significantly higher in hypertension(P<0.01). In hypertension group, PWVβ was positively correlated with β, Eρ, IMT and negatively correlated with AC, while there was no correlation among Eρ, β, AC, IMT and AI. Conclusions: E-Tracking technology can be used to reflect the vascular changes of hypertension, and it is a convenient and practical method to evaluate vascular endothelial function.
