目的：探讨血浆溶血磷脂酸（LPA ）测定及简易精神状态量表（MMSE）评分在门诊头晕患者风险的判断效果。方法：选择脑缺血导致头晕的对照组患者80例及高血压导致头晕的观察组患者80例 ，均行血浆 LPA 测定、MMSE 评分及相关性分析。结果：观察组患者血浆 LPA 浓度明显低于对照组，观察组 MMSE 总分、定点、记忆、注意、语言、抽象、执行评分明显低于对照组，差异有统计学意义（P＜0．05）。观察组认知功能缺损发生率明显高于对照组（P ＜0．05），多因素相关性分析显示血浆 LPA 与脑缺血是影响头晕门诊认知功能缺损的主要独立危险因素（P ＜0．05）。结论：血浆 LPA 测定及 MMSE 评分在门诊头晕患者的风险判断中有很好的价值，能有效区分头晕成因，联合检测两者水平可作为脑缺血与高血压的预测指标。%Objective :To investigate the clinic risk judgment effects for dizziness patients by the blood LPA values and MMSE scores .Methods :Selected 80 cases of cerebral ischemia leads to dizziness as the control group ,80 cases of hypertension leads to dizziness as the observation group ,all cases were given blood LPA values and MMSE scores measured and analyzed .Results :The plasma LPA concentrations of the observation group were significantly lower than those in the control group ,the MMSE total scores ,location ,memory ,attention ,lan‐guage ,ABSTRACT ,execution scores of the observation group were significantly lower than those in the control group ,the difference had statistically significant were compared (P < 0 .05 ) .The incidence of cognitive deficits of the observed group were significantly higher (P < 0 .05) ,multivariate analysis showed that plasma LPA and cere‐bral ischemia were the major independent risk factors for cognitive deficits (P < 0 .05 ) .Conclusion :Blood LPA values and MMSE scores for judging dizziness can effectively distinguish the causes ,its joint detection can be used as predictors of cerebral ischemia and hypertension .
