急性脑梗死患者脑微出血的发生及相关危险因素研究

目的探讨急性脑梗死后发生脑微出血（CMB）的危险因素。方法回顾性分析2008年9月-2011年10月于我院神经内科就诊的脑梗死患者的一般资料、临床、实验室及影像学检查资料，对比脑微出血阳性组与阴性组患者的各项记录指标，并采用多元回归方法对脑微出血阳性组患者进行危险因素分析。结果两组患者年龄、高血压、服用抗血小板药物、腔隙性脑梗死、脑白质稀疏等方面具有显著差异（P〈0．05），腔隙性脑梗死、脑自质稀疏、高血压、高血脂是急性脑梗死患者微出血发生的危险因素。结论脑微出血在急性脑梗死患者中有较高的发生率，其与腔隙性脑梗死、脑白质稀疏、高血压、高血脂密切相关。

The risk factors of cerebral microbleeds in acute cerebral infarction patients

Objective To obtain the risk factors about the acute cerebral infarctions complicating cerebral microbleeds （CMB）. Methods Retrospectively analyzed the normal data, clinical, laboratory and iconography results. And these results were compared between CMB （＋） and CMB （-） group. The logistic method was used for the analysis of risk factor for CMB. Re- stilts The situation of age, hypertension, antiplatelet drug, lacunar infarction, alba rarefaction were significantly different be- tween two groups. Lacunar infarction, alba rarefaction, hypertension and hyperlipemia were risk factors for CMB. Conclusion The rate of CMB is high among acute cerebral infarctions. And lacunar infarction, alba rarefaction, hypertension and hyper- lipemia are closely related with CMB.
