背景  
虽然在成像中脑病变3mm或更大与偶发性卒中相关,但小于3毫米的病变通常被忽略。

意义  
为了检查与亚临床脑损伤(只<3毫米,只≥3毫米,这两种病变)和白质高信号(WMHs)相关的中风风险。

方法  
该研究来自于ARIC(社区动脉粥样硬化风险)的社区人群队列研究。该研究数据是从1993年至1995年从两个ARIC地点的磁共振成像(MRI)数据收集的。1884名50岁〜73岁进行MRI检查的成年人,事先没有中风,平均随访14.5年。主要方法是研究MRI得出的病变(按大小),WMH评分(范围0-9),卒中事件,全因死亡率以及和中风有关的死亡率。风险比(HR)用比例风险模型进行估计。

结果
与无病变相比,只小于3mm的病变的人群中风的风险增加了两倍(HR,3.47[95%Cl,1.86至6.49]),大于等于3mm的病变的人群风险增加了一倍(HR,1.94[Cl,1.22至3.07]),具有两种病变的人群风险增加了8倍(HR,8.59[Cl,4.69至15.73]),WMH得分至少为3的人群风险增加了1倍(HR,2.14[Cl,1.45〜3.16])。只小于3mm的病变的人群中风风险相关性死亡增加了3倍(HR,3.05[Cl,1.04〜8.94]),具有两种大小病变的人群死亡风险增加了7倍(HR,6.97[Cl,2.03至23.93])。少数中风(特别是出血性)和少数参与者的病变只小于3毫米,或有病变的大小。

结论
非常小的病变脑血管可能与中风和死亡的危险性增加相关;小于3毫米或大于等于3毫米的病变的存在可能会导致一个更大的风险增加的结果。还需要更多的研究来确认这些结果,并提供更精确的估计。
