| 目的描述脑血管血液动力学检测指标(CVHI)的人群分布特征。方法以整群抽样的方法抽取中国东北等地区35岁及以上的人群25355例,在基线调查时检测CVHI,随访脑卒中的发病情况,分析和描述CVHI在非脑卒中、脑卒中发病前和脑卒中患者中的分布特征。结果随着年龄的增长,脑血管最大、最小值、平均血流速度和CVHI积分值呈明显的下降趋势,外周阻力、特性阻抗、脉搏波波速和动态阻力呈明显的上升趋势;男性的最大血流速度、外周阻力、临界压高于女性,脉搏波波速低于女性,差异有显著性(P<0.05);非脑卒中组的总积分、最小血流速度和外周阻力分别为95.0、10.23和75.8,脑卒中发病前检测组为51.25、6.71和122.72,脑卒中患者组为55.0、6.78和115.89,在控制性别和年龄的影响后,三组间差异均有非常显著性(P<0.01)。结论CVHI有明显的年龄变化趋势,脑卒中发病前后CVHI的主要检测指标出现明显异常 |

| Objective To describe the distribution of cerebral vascular hemodynamic indexes ( CVHI). Methods A number of 25 355 age 35 and over were selected in the NortheasTchina by cluster sampling. CVHI were checked during baseline survey and were followed to see the occurrence of stroke. Distribution of CVHI among non-stroke population, individuals prior to the onseTof stroke and patients with stroke were described.Results The CVHI accumulative score, Vmean, Vmax and Vmin were dramatically decreasing, buTRV, Zcv, Wvand DR were significantly increasing as age increased.Vmax, Rvand CP were significantly higher in males buTWV waslower than thaTof females.The CVHI accumulative score, Vminand RV were 95. 0, 10. 23 and 75. 8 in non-stroke population, 51. 25, 6. 71 and 122. 72 pre stroke group, and 55. 0, 6. 78 and 115. 89 in patients with stroke respectively.There were significanTdifferences among three groups after controlling of age and sex(P<0. 01).Conclusion Variance of CVHI wasclosely related to age, and there appeared a significanTabnormal of CVHI before and after stroke. |
