目的分析老年患者脑血管储备功能的血管危险因素。方法选取医院2016年1月-2017年1月接诊的100例老年患者作为研究对象,对其临床资料进行回顾性分析,按照是否存在血管危险因素将其分为危险组52例与正常组48例。使用颅多普勒和屏气试验评价所有患者的脑血管储备功能,对比2组研究对象的屏气指数(BIH)及脑血管危险指标与脑血管储备功能的相关性。结果危险组52例患者中有高血压有38例,糖尿病21例,高脂血症22例,吸烟18例。危险组患者BIH指数为(0.57±0.20)低于对照组患者的(0.99±0.30),差异有统计学意义(P<0.05)。根据患者的BIH指数,将糖尿病、高血压、高脂血症及吸烟作为自变量,建立线性模型,经回归分析显示,上述指标与BIH指数均存在相关性。结论吸烟、糖尿病、高血压及高脂血症会降低老年人的脑血管储备功能,针对危险因素临床应积极治疗,降低不良心脑血管事件的发生。
Objective To analyze the vascular risk factors of cerebral vascular reserve in elderly patients. Methods A total of 100 elderly patients admitted from January 2016 to January 2017 in our hospital were selected as the research objects. The clinical data of the elderly patients were retrospectively analyzed. According to the presence or absence of vascular risk factors, 52 cases were divided into the dangerous group and the normal group. example. Cerebral vascular reserve function was evaluated in all patients by using C-Doppler and breath-holding test. The relationship between cerebral hemopoiesis and cerebrovascular risk indexes was compared between two groups. Results There were 38 cases of hypertension, 21 cases of diabetes, 22 cases of hyperlipidemia and 18 cases of smoking in 52 patients in the dangerous group. The BIH index in the risk group was (0.57 ± 0.20) lower than that in the control group (0.99 ± 0.30), the difference was statistically significant (P <0.05). According to the patient’s BIH index, taking diabetes, hypertension, hyperlipidemia and smoking as independent variables, a linear model was established. The regression analysis showed that there was a correlation between these indexes and BIH index. Conclusions Smoking, diabetes mellitus, hypertension and hyperlipidemia may reduce cerebrovascular reserve in the elderly. Active treatment should be given to patients with risk factors to reduce the incidence of adverse cardiovascular and cerebrovascular events.
