    日常运动与颈动脉血管弹性的关系—基于超声射频信号技术的健康人群研究

    Daily physical activity improves carotid artery elasticity – a study based on ultrasound radio frequency signal technique

      摘要
    • 摘要:
        目的  基于超声射频技术探讨日常运动对颈动脉结构和弹性指标的影响。
        方法  纳入于空军军医大学唐都医院体检的健康受试者410例，调查过去一年内的运动情况。通过其日常低强度运动和高强度运动周频率和单次持续时间计算每周总运动量，分为无运动组、低运动量组、中运动量组和高运动量组；根据运动方式，分为单纯低强度运动组和混合低-高强度运动组。采用超声射频技术采集颈动脉图像，自动分析得到颈动脉内中膜厚度和颈动脉弹性参数，并进行组间比较。
        结果  不同日常运动量和运动方式对健康人群颈动脉内中膜厚度无显著影响。与无运动组相比，中、高运动量组颈动脉扩张性系数均显著升高（P<0.01）；中运动量组和高运动量组颈动脉顺应性系数显著高于无运动组(P<0.01）；高运动量组α僵硬度、β僵硬度和颈动脉局部舒张压显著低于无运动组（P<0.01）；高运动量组与无运动组和低运动量组相比，颈动脉PWV和增强指数均显著降低（P<0.01）。同单纯低强度运动组相比，混合低-高运动强度组β僵硬度、PWV和增强指数显著降低（P<0.05, P<0.05, P<0.01）。
        结论  日常中与高运动量健康人群颈动脉血管弹性优于无运动人群；混合低-高强度运动人群颈动脉血管弹性优于单纯低强度运动人群。

       

      Abstract:
        AIM  To study the relationship between daily physical activity and carotid artery elasticity based on ultrasound radio frequency technique.
        METHODS   Four hundred and ten healthy adults that underwent healthy examination in our hospital were included to collect their physical activity data of the past year. The total amount of physical activity (PA) was calculated based on weekly frequency and duration of moderate and vigorous PA. Subjects were then categorized into no PA, low PA, middle PA and high PA groups. Subjects were also grouped as simple moderate PA and mixed moderate-vigorous PA.
        RESULTS   The carotid intima media thickness were not influenced by the amount or pattern of daily PA. Compared with no PA group, the middle and high PA groups showed significantly increased carotid distensibility coefficient and compliance coefficient, and decreased pulse wave velocity (PWV) and augmentation index (AI) (P<0.05). Compared with low PA group, the high PA group showed significantly lower α stiffness, β stiffness, local diastolic pressure, PWV and AI (P<0.05). The β stiffness, PWV and AI was significantly reduced in mixed moderate-vigorous PA group than simple moderate PA group (P<0.05).
        CONCLUSION   The carotid artery elasticity of healthy people with middle and high amount of daily PA was better than that with no PA; and the carotid artery elasticity in healthy people with mixed moderate-vigorous PA was better than simple moderate PA.
