摘　　要：目的探讨血管回声跟踪（ET）技术对颈动脉单点脉搏波传导速度（PWVβ）的检测及其临床意义。方法检测20～、30～、40～、50～及≥60岁5个不同年龄组健康成人145例、高血压48例、糖尿病26例、终末期肾病20例的颈动脉PWVβ；比较性别间PWVβ差异；比较各组间PWVβ值与其同龄人传统两点PWV的差异；比较上述疾病与其同龄正常人的PWVβ的差异。结果上述5组的颈动脉PWVβ分别为4．6±0．6、5．9±1．1、6．1±1．2、6．7±1．2及（7．6±1．3）m／s；各组PWVβ均较传统的PWV值低，但二者相关性良好；不同性别间PWVβ无差异；高血压及终末期肾病患者PWVβ增高，而糖尿病患者PWVβ与同龄正常人无明显差异。结论PWVβ随着年龄的增高而增高且与传统的PWV相关良好；PWVβ能较好地反映不同年龄及疾病的动脉弹性状态；用超声ET技术检测的PWVβ能较敏感地反映这些变化。Objective To detect the carotid artery one point pulse wave velocity （PWVβ） using elastograplay tracking （ET） technique. Methods With ET technique the PWVβ of carotid artery in 145 normal adults, 48 cases with hypertension （HBP）, 26 cases with 2 type diabetes （DM） and 20 cases with end-stage renal disease （ESRD） were calculated. The normal adults were divided into five groups according to ages：20-29,30-39,40-49,50-59 and≥60. The （PWVβ） s between gender, age, diseases and normal adults were compared using SAS 6.12 statistic software. The parameter of one point PWVβ3 and traditional two point PWV were also compared. Results The PWVβ were 4.6±0.6 m/s, 5.9±6.5 m/s, 6.1±1.2 m/s, 6.7±1.2 m/s and7. 6±1.3 m/s respectively in the five groups mentioned above and these data were correlated significantly with traditional two point PWV. There was no difference of PWVβ between gender. The PWVβ had no difference between DM and normal. Conclusions The carotid PWVβ detected by ET may be a promising parameter of elasticity. It was correlated significantly with traditional two point PWV. The PWVβ was increased with age and diseases such as HBP and ESRD.
