摘　　要：目的：研究健康人颈动脉结构、血流参数与年龄的相关性及其意义。方法：204例健康人按年龄分为4组：1组52例，30．44岁；2组51例，45．59岁；3组50例，60-74岁；4组51例，≥75岁。对其进行颈动脉超声检查。结果：年龄是影响健康人颈动脉结构、各血流参数的独立因素。内膜中层厚度增厚是动脉粥样硬化的早期改变。结论：颈动脉超声多参数评估有助于更好的理解血管增龄。Objective： To study the relationship between the changes of carotid structure and blood stream parameters and the age and its implication in healthy adults. Methods： According to age, 204 healthy adults were divided into 4 groups： group 1 （52 adults aged 30 to 44 years）, group 2 （51 adults aged 45 to 59 years）, group 3 （50 adults aged 60 to 74 years）, and group 4 （ 51 adults aged 75 years or older）. Carotid ultrasonngraphy was performed. Results： Age was the only independent factor that affected the carotid structure and function in healthy adults. The thickening of intima-media thickness was an early change of atherosclerosis. Conclusions ： The multiparameter assessment of carotid ultrasonography might contribute to a better understanding of vascular aging.
