摘要/Abstract

摘要： 目的探究广泛的血管周围间隙（extensive perivascular space，EPVS）负荷与缺血性卒中（ischemic stroke，IS）（包括其亚型）和短暂性脑缺血发作（transient ischemic attack，TIA）之间是否存在遗传因果关系。方法利用来自大规模全基因组关联研究的汇总数据，通过孟德尔随机化（Mendelian randomization，MR）分析，研究不同部位的EPVS与IS及其亚型和TIA之间的关联。采用多种MR方法评估EPVS负荷与IS及其亚型和TIA之间的因果关系。应用多变量MR以减轻潜在的混杂因素，并进行敏感性分析以增强结果的稳健性。随后，利用Meta分析整合来自不同来源的、不同部位EPVS负荷与IS之间因果关系的数据。此外，采用反向MR观察各种IS类型对EPVS的影响。最后，进行连锁不平衡评分回归，以评估暴露和结果之间的遗传相关性。结果脑白质（OR=1.12，95% CI:1.01~1.25；P=0.04）和基底节（OR=1.57，95% CI:1.30~1.89；P<0.01）中的EPVS负荷均是IS的显著危险因素。基底节中的EPVS负荷也是小动脉闭塞型IS的危险因素（OR=4.56；95% CI:2.57~8.27；P=5.95×10-7）。此外，IS和TIA后，基底节EPVS负荷似乎也存在潜在的增加。结论广泛的白质和基底节血管周围间隙负荷可能是预测IS的重要指标。

Abstract: Objective To investigate the association between extensive perivascular space (EPVS) burden in different locations and ischemic stroke (IS), its subtypes, and transient ischemic attack (TIA) through Mendelian randomization (MR) analysis. Methods The summary data from large-scale Genome-wide Association Studies (GWAS) and various MR methods were employed. We applied multivariable MR to mitigate potential confounding factors and conduct sensitivity analyses to enhance result robustness. Subsequently, meta-analysis was utilized to integrate causal relationships between EPVS burden in different locations and IS from various sources. Additionally, reverse MR was employed to observe the impact of various IS types on EPVS burden. Finally, linkage disequilibrium score regression was conducted to assess genetic correlations between exposures and outcomes. Results EPVS burden in both the white matter (OR=1.12, 95% CI: 1.01-1.25; P = 0.04) and basal ganglia (OR=1.57, 95% CI:1.30-1.89; P < 0.01) are significant risk factors for IS. EPVS burden in the basal ganglia is also a risk for IS (small-vessel) (OR=4.56,95% CI:2.57-8.27; P = 5.95×10-7). After IS and TIA there seems to be a potential increase in extensive basal ganglia perivascular space burden. Conclusions Extensive white matter perivascular space burden and extensive basal ganglia perivascular space burden may serve as important indicators to predict IS.
