摘要
目的应用血管回声跟踪技术(eTRACKING,ET)对吸烟者颈动脉弹性功能进行研究。方法选择89名吸烟者,65名非吸烟者,应用ET测量双侧颈总动脉收缩期内径(Dd)、舒张期内径(Ds)、血管内-中膜厚度(IMT)、僵硬度(β)、压力-应变弹性系数(Ep)、顺应性(AC)、膨大指数(AI)及脉搏波传导速度(PWVβ)进行对比分析。结果两组中左、右颈动脉各项参数间比较,差异无统计学意义(P>0.05);吸烟组和非吸烟组Dd、Ds、IMT比较,差异无统计学意义(P>0.05);吸烟组β、Ep、AI及PW Vβ均高于非吸烟组,差异有统计学意义(P<0.05);吸烟组AC较非吸烟组明显降低,差异有统计学意义(P<0.05)。结论超声ET技术可便捷无创评价吸烟者颈动脉弹性功能的变化,为血管形态学改变前的早期动脉硬化诊断及倡导戒烟提供依据。
Objective Using echo-tracking technology（ET） to study the smokers＇ carotid artery elasticity function. Materials and Methods 89 smokers and 65 non-smokers were included in this study.Parameters related to arteriosclerosis gained by ET at double side carotid artery, including diastolic diameter（Dd）, systolic diameter（Ds）, intimamedia thickness（IMT）, stiffness parameters（B）, pressure-strain elastic modulus（EP）, arterial compliance（AC）,pulse amplification index（AI）, and pulse wave transmission speed（PWV B） were recorded and analyzed. Results There Was no significant difference of all parameters between the double sides carotid artery （P〉0.05）; Dd, Ds, IMT also showed no significant difference between smokers and non-smokers. （P〉0.05）; 13 , Ep, AI and PWV 13 were higher in smoker- group than non-smoker-group, while AC was lower than non-smokers.There were statistic differences among the two groups （P〈0.05）. Conclusion ET can be used conveniently and non-invasively to access the smokers＇ carotid artery elasticity function,and find early arteriosclerosis accurately
