摘　　要：目的采用血管回声跟踪(ET)技术检测颈动脉弹性并探讨其在心血管危险分层中的临床应用价值。方法选择87名60岁以下男性体检者,依据我国缺血性心血管疾病10年发病危险度评估表将其分为低危组、中危组和高危组。测量各组受检者血压、体质量指数并测定血脂、血糖。超声测量内中膜厚度(IMT),ET技术检测右颈动脉弹性参数:僵硬度指数(β)、弹性模量(Ep)、顺应性(AC)、膨大指数(AI)、单点脉搏波传导速度(PWVβ)。结果高危组年龄、体质量指数高于低危组;高危组收缩压高于中危组,中危组高于低危组。高危组甘油三酯和高密度脂蛋白高于低危组(P<0.05);高危组空腹血糖水平高于中危组(P<0.05),但中危组与低危组血糖差异无统计学意义;高危组总胆固醇高于中危组,中危组高于低危组(P均<0.05)。高危组β、Ep均高于中危组,中危组高于低危组(P均<0.05);高危组AC、PWVβ和IMT高于低危组,但与中危组比较差异无统计学意义。结论 ET技术可检测颈动脉弹性变化、评价亚临床动脉粥样硬化,为临床进行心血管危险分层提供重要信息。Objective To assess elasticity of carotid artery with echo tracking（ET）and discuss its clinic value in cardiovascular risk stratification.Methods Totally 87 men were divided into three groups（low risk group,intermediate risk group,high risk group）by risk scale of 10-year incidence of ischemic cardiovascular disease in China.Blood pressure,blood fat,blood glucose were measured and body mass index was calculated.All subjects underwent ultrasonography and ET scan.Intima-media thickness（IMT）and stiffness index（β）,elastic modulus（Ep）,arterial compliance（AC）,argumentation index（AI）and pulse wave velocity（PWVβ）were measured.Results 1Age and body mass index in high risk group were higher than those in low risk group;systolic blood pressure in high risk group was higher than that in intermediate risk group,and which intermediate risk higher than high risk group.2Triglyceride and high density lipoprotein in high risk group were higher than those in low risk group;blood glucose in high risk group was higher than that in intermediate risk group but there was no difference between intermediate and low risk group;total cholesterol in high risk group was higher than that in intermediate group and that in intermediate group was higher than that in low risk group.3βand Ep in high risk group were higher than those in intermediate group,those in intermediate group were higher than those in low group.AC,PWVβand IMT in high risk group were higher than those in low risk group,and there was no differences between high risk group and intermediate group.Conclusion ET could assess elasticity of carotid and evaluate subclinical arteriosclerosis,and provide important messages in cardiovascular risk stratification.
