目的 :观察老年高血压病人脑血管血流动力学变化。方法 :将老年人 (6 5岁以上 )查体人群 2 13例 ,分为高血压组和正常血压组 ,对两组均行脑血管血流动力学指标检测。结果 :高血压组Vmin(最低血流速度 )、RV(外周阻力 )和WV(脉搏波波速 )分别为 90 3%、81 4和 79 8% ,均分别显著高于血压正常组 ,两组比较 ,差异非常显著 (P <0 0 1)。结论 :长期高血压病可导致脑血流动力学改变 Objective: To observe the changes of cerebrovascular hemodynamics in elderly hypertensive patients. Methods: Twenty-three elderly people (over 65 years old) were divided into two groups: hypertension group and normotensive group. Cerebral vascular hemodynamic parameters were measured in both groups. Results: Vmin, RV and WV were 90 3%, 81 4 and 79 8% respectively in hypertension group, which were significantly higher than those in normotensive group , The difference was significant (P <0.01). Conclusion: Long-term hypertension can lead to cerebral hemodynamic changes
