Stroke:大动脉粥样硬化患者他汀类药物预处理和微栓子信号

2018-07-10 xing.T MedSci原创

由此可见,SP似乎与大动脉粥样硬化引起的急性脑缺血患者的MES发病率和负担较低有关。

有限的数据表明大动脉粥样硬化所致的急性脑缺血患者服用他汀类药物预处理(SP)可能与复发性卒中风险降低有关,因为经颅多普勒监测期间微栓子信号(MES)的发生率降低。

近日,卒中领域权威杂志Stroke上发表了一篇研究文章,研究人员对报告了有症状的(≥50%)大动脉粥样硬化所致的急性脑缺血患者患有/不患有MES或MES负担(根据SP状态分类)的观察性研究进行了系统评价和荟萃分析。在部分发表数据的研究中,作者联系了作者得到了之前未发表的数据。研究人员还对根据SP状态分类的MES负担数据进行了研究的敏感性分析,并对接受高剂量SP(阿托伐他汀80mg或罗苏伐他汀40mg每日)的患者进行了额外的亚组分析。

研究人员确定了7个符合条件的研究(共有610名患者,54%的患者接受SP)。SP与经颅多普勒监测期间MES风险降低相关(风险比=0.67; 95%CI为0.45-0.98),研究之间存在显著的异质性(I2=52%)。在报告了MES负担(n=4)的研究中,与没有SP的患者相比,接受SP的患者MES数量显著降低(平均差异=-0.92; 95%CI为-1.64至-0.19),没有证据表明研究之间存在异质性(I2=49%)。亚组分析显示较高剂量的SP降低了MES的风险(风险比=0.23; 95%CI为0.06-0.88),没有证据表明研究之间存在异质性(I2=0%)。

由此可见,SP似乎与大动脉粥样硬化引起的急性脑缺血患者的MES发病率和负担较低有关。

脑白质高信号(WMH)是脑小血管病(SVD)的重要表现,并很大程度上增加痴呆,卒中以及残疾的发生风险。尽管其对临床患者和整个社会有相当大的影响,但目前对SVD以及WMH的病因知之甚少。研究显示WMH与常见的血管性危险因素(VRFs)相关,如高血压,高脂血症,糖尿病,吸烟以及颈动脉狭窄等。既往观察性随机对照试验研究显示高血压与WMH的进展相关,控制血压可以延缓WMH的进展。然而在一项大型的随机对照试
