正常人脑血管血流动力学检测参数的分布特征

Distribution of cerebrovascular hemodynamic parameters in normal population

    摘要
  • 摘要:
      目的   描述正常人脑血管血流动力学(CVHD)检测参数的分布特征。
      方法   以分层随机抽样的方法抽取东北、华北、西南、西北、华东、华南等6个行政大区, 26个城市的3~92岁无卒中病史和危险因素暴露史的健康社区居民14480例, 进行CVHD指标检测。将检测结果按照年龄、性别、地区和左右侧检测部位分组计算均数和标准差, 比较和分析各组的分布特征及组间差异。
      结果   在10对检测指标中, 颈总动脉血流速度的最大值(Vmax)、最小值(Vmin)、平均值(Vmean)随着年龄的增长呈显著的下降趋势, 而脑血管外周阻力(Rv)、特性阻抗(Zcv)、脉搏波波速(Wv)、动态阻力(DR), 临界压(CP)等指标随着年龄的增长呈显著的上升趋势, Qmean和舒张压与临界压之差(DP)无明显的年龄升降趋势; 男性的Qmean、Vmax、Rv、DR、CP和DP高于女性, 而Wv和Zcv低于女性; 左侧的Qmean、Vmean、Vmax、Vmin、Wv、Zcv和CP等指标高于右侧, 而Rv、DR和DP低于右侧; 不同地区间各指标的分布无明显差异。
      结论   不同年龄、性别和左右检测部位间CVHD检测指标有明显差异。

     

    Abstract:
      Objective   To describe distribution of cerebrovascular hemodynamic (CVHD) parameters in normal population.
      Methods   14 480 participants without history of stroke and free of stroke risk factor exposure were randomly selected from 26 cities in the northeast, north, east, northwest, south and southwest of China. CVHD parameters were checked and means were calculated, which were divided by age, sex, area, and check position. Characteristics of distribution were described and differences between groups were compared.
      Results   Carotid blood velocity, such as Vmax, Vmin, Vmean were dramatically decreased, but cerebral Rv, Zcv, Wv, DP, and CP were significantly increased with aging. Qmean and DP had no significant age trends. Qmean, Vmax, Rv, DR, CP and DP in male were higher than that in female. While Wv and Zcv in female was higher than that in male. Left carotid Qmean, Vmean, Vmax, Vmin, Wv, Zcv and CP were higher than that of right. However, Rv, DR and DP were lower than that of right. There were no obvious difference among areas.
      Conclusion   Obvious distributional difference of CV HD parameters are found in age groups, sex, and checking position.
