成年女性年龄分层与颈总动脉结构重塑相关性研究

应用高频超声技术评估增龄对成年女性颈总动脉形态的影响。3886例成年女性每10岁为一个年龄层组，采用高频超声技术观察成年女性颈总动脉的管径及内-中膜的厚度。年龄分层分析显示女性自20岁起各年龄层的颈总动脉的管径和内-中膜的厚度伴随着年龄的增长而逐渐增加，50岁以后血管老化增速。年龄对女性颈总动脉内-中膜厚度的影响大于颈总动脉管径，血管管径因IMT增长而代偿性扩张的能力随着年龄的增加而呈现下降趋势，增龄可使成年女性颈总动脉发生衰老性结构重塑。

Studies of Correlation Between Stratification of Age and Common Carotid Artery Aging Remodeling in Adult Women

Application of high frequency ultrasound technology evaluate aging influence on common carotid artery(CCA) morphological changes in adult women. 3886 cases of adult women were categorized according to age. CCA in diameter and in intima-media thinkness(IMT) were observed by high frequency ultrasound. Data of age-stratified analyses of the women suggested that CCA diameter and IMT were increase accompanied with the growthing of age after 20-year-old. Vascular aging growth was obvious apparent among those who were older than 50 years. The influence of age on CCA IMT was greater than that of diameter. In the CCA, with the increasing of ages, the ability to compensatory expansion of lumen area had declined with greater thickness. The aging can cause age-related remodeling of CCA in adult women.
