脑卒中所致老年急诊头晕的临床特点分析

目的探讨脑卒中所致老年急诊头晕的临床特点。方法选择173例年龄≥60岁的急诊头晕患者,根据诊断分为脑卒中组37例和非脑卒中组136例,回顾性分析2组患者临床特点的差异,并进行logistic分析。结果脑卒中组患者发病时血压≥140/90mm Hg(1mm Hg=0.133kPa)、不伴肢体无力的语言障碍、偏侧肢体无力、肢体和(或)躯干共济失调、视野缺损和(或)视物成双的发生率及症状持续时间≥60min明显高于非脑卒中组(P<0.05);高血压(OR=8.383,95%CI:2.006³5.035)、发病时血压≥140/90mm Hg(OR=10.497,95%CI:2.01435.035)、发病时血压≥140/90mm Hg(OR=10.497,95%CI:2.014⁵4.710)、不伴肢体无力的语言障碍(OR=9.315,95%CI:1.49354.710)、不伴肢体无力的语言障碍(OR=9.315,95%CI:1.493⁵8.131)、偏侧肢体无力(OR=2.821,95%CI:1.27158.131)、偏侧肢体无力(OR=2.821,95%CI:1.271⁶.260)、肢体和(或)躯干共济失调(OR=9.917,95%CI:1.9956.260)、肢体和(或)躯干共济失调(OR=9.917,95%CI:1.995⁴9.287)、视野缺损和(或)视物成双(OR=6.288,95%CI:1.45549.287)、视野缺损和(或)视物成双(OR=6.288,95%CI:1.455²7.172)和症状持续时间≥60min(OR=10.340,95%CI:1.95027.172)和症状持续时间≥60min(OR=10.340,95%CI:1.950⁵4.811)是预测患者发生脑卒中的独立危险因素。结论高血压、发病时血压升高、不伴肢体无力的语言障碍、偏侧肢体无力、肢体和(或)躯干共济失调、视野缺损和(或)视物成双及症状持续时间对评估老年头晕患者发生脑卒中的风险有重要价值。

Clinical characteristics of ischemic stroke-induced emergency dizziness in elderly people

Objective To study the clinical characteristics of emergency dizziness induced by ischemic stroke(IS)in elderly people.Methods One hundred and seventy-three emergency dizziness patients with their age≥ 60 years were divided into IS group(n=37)and non-IS group(n=136).Their clinical characteristics were analyzed by logistic regression analysis.Results The incidence of BP≥140/90 mm Hg(1mm Hg=0.133kPa)at the disease onset extremity weaknessfree speech disturbance,unilateral weakness,extremity and/or gait ataxia,visual field defect and/or diplopia,and symptom duration were significantly higher in IS patients than in non-IS patients(P<0.05).Hypertension history,blood pressure≥140/90 mm Hg at the disease onset,extremity weakness-free speech disturbance,unilateral weakness,extremity and/or gait ataxia,visual field defect and/or diplopia,and symptom duration were the independent risk factors for IS in elderly dizziness patients(P<0.05,P<0.01).Conclusion Hypertension,blood pressure≥140/90 mm Hg at the disease onset,extremity weakness-free speech disturbance,unilateral weakness,extremity and/or gait ataxia,visual field defect and/or diplopia,and symptom duration are of great value in assessing the risk of IS in elderly dizziness patients.
