血管危险因素对老年人良性阵发性位置性眩晕发病的影响

Effect of vascular risk factors on the onset of benign paroxysmal positional vertigo in the elderly

目的分析心血管危险因素(CVRFs)对老年人良性阵发性位置性眩晕(BPPV)的影响。方法选取2018年10月至2020年10月八里庄社区卫生服务中心全科的34例BPPV老年患者作为试验组,选取同期与试验组年龄、性别相匹配,到健康体检科参加健康体检无BPPV病史的34例老年人作为对照组。比较两组的7个CVRFs指标,包括体重指数(BMI)、血压、血糖、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)以及2个颈动脉超声诊断指标[内中膜厚度(IMT)和粥样斑块]。结果两组的CVRFs和颈动脉粥样斑块发生率比较,差异无统计学意义(P>0.05)。BPPV组的颈动脉IMT严重程度高于对照组,差异有统计学意义(P<0.05)。结论CVRFs和颈动脉粥样斑块并非老年人BPPV发病的危险因素,而颈动脉IMT可作为老年性BPPV风险评估和预警的参考指标。

Objective To analyze the effect of cardiovascular risk factors(CVRFs)on benign paroxysmal positional vertigo(BPPV)in the elderly.Methods A total of 34 elderly patients with BPPV in the General Department of Balizhuang Community Health Service Center from October 2018 to October 2020 were selected as the experimental group.During the same period,34 elderly people who matched the age and gender of the experimental group and took physical examination in the Physical Examination Department in the same period,and had no history of BPPV were selected as the control group.Seven CVRFs indexes including body mass index(BMI),blood pressure,blood glucose,serum total cholesterol(TC),triglyceride(TG),low density lipoprotein cholesterol(LDL-C)and high density lipoprotein cholesterol(HDL-C)as well as 2 carotid ultrasound diagnosis indexes including intima-media thickness(IMT)and atherosclerotic plaque were compared between two groups.Results There were no significant differences in CVRFs and incidence of carotid atherosclerotic plaque between the two group(P>0.05).The severity of carotid IMT in the BPPV group was higher than that in the control group,and the difference was statistically significant(P<0.05).Conclusion CVRFs and carotid atherosclerotic plaque are not independent risk factors of BPPV in the elderly,and carotid IMT can be used as a reference index for risk assessment and early warning of senile BPPV.
