老年患者常见血管危险因素与脑血管储备功能的相关性研究

目的对老年患者常见血管危险因素和脑血管储备功能之间的关联性进行研究和探索。方法对2009年7月～2012年7月广东省高州市第二人民医院收治和进行体检的680例老年患者临床资料进行回顾性分析。按照是否存在血管危险因素分为危险因素组(360例)和对照组(320例)。根据患者经颅多普勒超声情况和屏气试验情况,对颅内血管反应情况进行评估,对屏气指数进行计算,做出患者脑血管储备功能评价。结果危险因素组的屏气指数(BHI)(0.56±0.17)明显低于正常对照组(0.98±0.29),差异具有统计学意义(P<0.05)。结论如果老年患者存在血管危险因素,则其脑血管储备功能会出现下降,研究表明糖尿病、高血压、高血脂、吸烟习惯等对血管储备功能影响较明显,应该引起高度重视。

Objective To study and explore the correlation between elderly patients with common vascular risk factors and cerebrovascular reserve function. Methods From July 2009 to July 2012 were our medical and of 680 cases of elderly patients clinical data were retrospectively analyzed. According to whether there is vascular risk factors are divided into risk factors group and control group. According to patients with transcranial doppler ultrasonography and breathless test of intracranial vascular response assessment, the breathless index calculation, make patient cerebrovascular reserve function evaluation. Results The risk factors group breath-hold index BHI （0.56 ± 0.17） was significantly lower than that in normal control group （0.98 ± 0.29）, the difference was statistically significant （P〈0.05）. Conclusion If the elderly patients with vascular risk factors exist, the cerebrovascular reserve function will decline, studies show that diabetes, high blood pressure, high cholesterol, smoking habits on the vascular reserve function effect is more apparent, should draw high attention.
