目的 评估4种脑卒中风险评分量表对后循环缺血性孤立性眩晕的诊断价值.方法 选择409例以头晕或眩晕为惟一主诉的患者,在入院24 h内运用改良弗明汉卒中量表(Framingham stroke profile,FSP)评分、ABCD2 (age,blood pressure,clinicalfeatures,durationofsymptoms,diabetes)评分、Essen卒中风险评分量表(Essen stroke risk score,ESRS)、国人缺血性心血管病10年发病危险评估(ischemic cardiovascular disease,ICVD)脑卒中风险评分量表进行评定,根据临床特征、辅助检查等将患者分为后循环缺血性孤立性眩晕组(A组)77例和非后循环缺血性孤立性眩晕组(B组)332例,通过ROC曲线判断4个量表对后循环缺血性孤立性眩晕的诊断价值.结果 A组FSP、ABCD2、ESRS和ICVD评分高于B组(A组分别为男20分、女19分;3分;3分;男9分、女9分;B组分别为男15分、女14分;2分;1分;男6分、女6分.Z值-7.769～-4.662,P＜0.01).FSP、ABCD2、ESRS和ICVD 4种量表评分ROC曲线下面积分别为75.8％、75.9％、77.7％和75.6％,预测后循环缺血性孤立性眩晕的临界值分别为18分、3分、3分和6分,预测准确性分别为72.61％、69.68％、74.82％和68.46％.结论 4种量表对后循环缺血性眩晕患者均有预测诊断价值.%Objective To evaluate the value of four stroke risk scores used in the diagnosis of posterior circulation ischemia isolated vertigo.Methods 409 patients with the only complaint of dizziness/vertigo were scored according to the Framingham stroke profile (FSP),age,blood pressure,clinicalfeatures,durationofsymptoms,diabetes (ABCD2),Essen stroke risk score (ESRS) and ischemic cardiovascular disease (ICVD) within 24 h after admission.The patients were divided into posterior circulation ischemia isolated vertigo group (group A,n=77) and non-posterior circulation ischemia isolated vertigo group (group B,n=332) according to their clinical characteristics and auxiliary examination findings.The role of the 4 scales in diagnosis of posterior circulation ischemic isolated vertigo was assessed according to the ROC curve.Results The FSP,ABCD2,ESRS and ICVD scores were higher in goup A than in group B (A group:males 20、females 19;3;3;males 9、females 9;B group:males 15、females 14;2;1;males 6、females 6,P＜ 0.01).The area under the ROC curve was 75.8％,75.9％,77.7％,75.6％ respectively for the 4 scales.The score of the 4 scales in predicting posterior circulation ischemia isolated vertigo was 18,3,3 and 6 respectively with an accuracy of 72.61％,69.68 ％,74.82 ％ and 68.46 ％.Conclusion The 4 scales play an important role in diagnosis of posterior circulation ischemia isolated vertigo.
