摘要
BACKGROUND AND OBJECTIVES: Brain frailty impairs the ability to compensate for brain dysfunction and is linked to worse outcomes after stroke. Stroke severity at presentation is a key determinant of outcomes in acute ischemic stroke. This study aimed to examine the impact of brain frailty on initial stroke severity and recovery in acute ischemic stroke (AIS) patients undergoing endovascular thrombectomy (EVT). METHODS: We conducted a post hoc analysis of the ESCAPE-NA1 randomized-controlled trial that investigated the efficacy and safety of the neuroprotectant nerinetide in patients with AIS who received EVT. Brain frailty markers (cortical atrophy, subcortical atrophy, white matter hyperintensities, chronic infarcts) were visually assessed from baseline noncontrast CT scans. We explored the association between these markers and admission stroke severity (National Institutes of Health Stroke Scale [NIHSS] score) using multivariable quantile regression. We also assessed the NIHSS trajectory over 90 days using repeated-measures analysis. Models were adjusted for relevant covariates. RESULTS: = 0.05). DISCUSSION: This study highlights the association of brain frailty with the clinical presentation and recovery trajectory of patients with AIS undergoing EVT. Specifically, cortical atrophy was independently associated with baseline stroke severity, and the total burden of brain frailty was independently associated with NIHSS recovery trajectories. The results emphasize the importance of considering brain frailty in acute stroke management and prognostication.
