血管回声跟踪技术评价冠心病颈总动脉弹性的应用

目的评价血管回声跟踪技术在冠心病患者颈总动脉弹性的应用价值。方法冠心病组56例,正常对照组38例。应用血管回声跟踪技术评估颈总动脉弹性参数,包括僵硬度(β)、弹性模量(EP)、顺应性(AC)、膨大指数(AI)及脉搏波传导速度(PWVβ)5项生理参数,并对上述参数进行统计学分析。结果冠心组颈总动脉β、EP、PWVβ较正常对照组增高(P0.01),AC较正常对照组降低(P0.01),AI较正常对照组增高(P0.05)。结论应用血管回声跟踪技术有助于评价冠心病患者颈总动脉弹性的功能改变。

Evaluation of carotid elasticity in patients with coronary artery disease by echo tracking technique

Objective To study the elastic function ofcarotid artery by echo tracking （ET） technique in patients with coronary artery disease （CAD）.Methods There were 56 cases in the CAD group and 38 cases in the normal control group. ET technique was used to evaluate the carotid elastic modulus, such as stiffness parameter（β）, pressure-strain elastic modulus（EP）, arterial compliance（AC）, augment index, pulse wave conducting velocity （PWVβ）. ALL these parameters were analyzed statistically. Results Compared with the normal group, Ep, β, PWVβ ofcarotid artery were significantly higher in the CAD group （P〈 0.01）, and AC was significantly lower than that ofcontrol group P〈 0.01）. AI of carotid artery was higher in the CAD group （P 〈 0.05）. Conclusion ET technique can be used to evaluate the carotid elastic function in patients with CAD.
