| 目的 应用超声射频信号的血管内-中膜分析技术（QIMT）、血管硬度定量分析技术(QAS) 评价健康成人颈总动脉结构及功能。方法 360例健康成人根据年龄分成3组：青年组（20~39岁组）、中年组（40~59岁组）和老年组（60~79岁组），每组均120人，分别应用QIMT测量双侧颈总动脉内-中膜厚度（IMT），QAS技术测量双侧颈总动脉的弹性参数，包括扩张系数（DD）、顺应性系数（CC）、硬度指数(α、β)、脉搏波传导速度(PWV)，分析各项参数在双侧颈总动脉、不同性别、不同年龄组之间的差异。结果 ①颈总动脉QIMT和QAS指标在颈总动脉左右两侧组间差异均无统计学意义；②颈总动脉DC在两性别组之间的差异有统计学意义，男性高于女性(P<0.05)；③从青年组经中年组到老年组，IMT依次增厚、DC依次减小，差异均有统计学意义(P<0.05)，与青年组比较，中年组和老年组的CC减低，α、β及PWV增加，差异有统计学意义(P<0.05)，而在中年组与老年组之间差异没有统计学意义。结论 健康成人颈总动脉结构及功能随年龄、性别变化存在差异。 |

| Abstract: |
| Objective To evaluate common carotid arterialstructure and functionin healthy adults using quality intima-media thickness（QIMT） and quantitative artery stiffness(QAS). Methods 360 subjects were divided into 3 groups based on age: young group(20~39 years), middle-age group(40~59 years) and aged group(60~79 years), 120 persons in each group. The bilateral common carotids arterial intima-media thickness(IMT) and elasticity coefficient were respectively measured by QIMT and QAS. Distention coefficient (DC)、compliance coefficient(CC)、stiffness parameter(α、β) and pulse wave velocity(PWV) were analyzed. The results of parameters among bilateral carotids , different genders anddifferent ages were compared and discussed. Results ①There were no statistically significant differences in IMT, DC, CC, α, β and PWV between bilateral common carotids groups. ②DC of male group is higher than that of female group, there were statistically significant differences (P<0.05). ③ IMT values increased while DC values decreased from young group to middle-age group and aged group. Compared with young group, CC values decreased whileα, β and PWV values increased in middle-age group and aged group(P<0.05), but there were no statistical differences between middle-age group and aged group. Conclusions Age and gende could influent structure and function of common carotid artery in healthy adults. |
