Cellular senescence, a permanent halt in cell division due to stress, spurs functional and structural changes, contributing to vascular aging characterized by endothelial dysfunction and vascular remodeling. This process raises the risk of ischemic stroke (IS) in older individuals, with its mechanisms still not completely understood despite ongoing research efforts. In this review, we have analyzed the impact of vascular aging on increasing susceptibility and exacerbating the pathology of IS. We have emphasized the detrimental effects of endothelial dysfunction and vascular remodeling influenced by oxidative stress and inflammatory response on vascular aging and IS. Our goal is to aid the understanding of vascular aging and IS pathogenesis, particularly benefiting older adults with high risk of IS.
细胞衰老,即由于压力导致的细胞分裂永久停止,会引发功能和结构的变化,导致血管老化,表现为内皮功能障碍和血管重构。这一过程增加了老年人发生缺血性脑卒中(IS)的风险,尽管目前正在进行研究,但其机制仍不完全清楚。在这篇综述中,我们分析了血管老化对增加 IS 易感性和加重其病理的影响。我们强调了氧化应激和炎症反应对血管老化和 IS 影响的内皮功能障碍和血管重构的有害作用。我们的目标是帮助理解血管老化和 IS 的发病机制,特别是对有发生 IS 高风险的老年人有益。
