IntroductionIt could be theorised that liver fibrosis and acute ischemic stroke (AIS) are related by inflammatory changes, but few studied this link, let alone in patients receiving intravenous thrombolysis (IVT). The Fibrosis (FIB)-4 index is an established rapid score to detect liver fibrosis. We aimed to understand the role of FIB-4 in predicting AIS subtype, severity and outcomes after IVT. MethodsAIS patients receiving IVT without severe liver derangement from 2006 to 2018 at a stroke centre were studied. Stroke subtype was defined using Trial of Org 10172 in Acute Stroke Treatment. Moderate and severe stroke was defined as National Institutes of Health Stroke Scale (NIHSS) ≥10. FIB-4 index was stratified into no advanced fibrosis (FIB-4 3.25). The primary outcome - functional outcome at 90-days using the modified Rankin Scale (mRS) - was analysed by ordinal shift analysis. Multivariable adjusted logistic regression evaluated associations of FIB-4 with stroke severity, functional independence (90-day mRS 0-2 vs 3-6), 90-day mortality, and symptomatic intracranial hemorrhage (SICH). ResultsAmong 900 patients, higher median FIB-4 was seen in cardioembolic stroke (CES) than non-CES (1.93 [IQR1.39-2.81] vs 1.27 [IQR0.92-1.90], p
