Abstract

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 Northeast China 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 onset of stroke and patients with stroke were described.

RESULTS

The CVHI accumulative score, V(mean), V(max) and V(min) were dramatically decreasing, but RV, Zcv, WV and DR were significantly increasing as age increased. V(max), RV and CP were significantly higher in males but WV was lower than that of females. The CVHI accumulative score, V(min) and 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 significant differences among three groups after controlling of age and sex (P < 0.01).

CONCLUSION

Variance of CVHI was closely related to age, and there appeared a significant abnormal of CVHI before and after stroke.

摘要

目的

描述脑血管血流动力学指标（CVHI）的分布情况。

方法

采用整群抽样的方法，在中国东北地区选取25355名35岁及以上人群。在基线调查时检测CVHI，并随访观察中风的发生情况。描述了非中风人群、中风发作前个体和中风患者中CVHI的分布情况。

结果

随着年龄的增加，CVHI累积评分、V（均值）、V（最大值）和V（最小值）显著降低，但阻力指数（RV）、脑血管阻力（Zcv）、脉搏波速度（WV）和动态阻力（DR）显著升高。男性的V（最大值）、RV和临界压力（CP）显著高于女性，但WV低于女性。非中风人群的CVHI累积评分、V（最小值）和RV分别为95.0、10.23和75.8，中风前组分别为51.25、6.71和122.72，中风患者分别为55.0、6.78和115.89。在控制年龄和性别后，三组之间存在显著差异（P < 0.01）。
