The presence of high fibrinogen and low albumin levels in serum is associated with a negative prognosis in acute ischemic stroke (AIS). Fibrinogen‐to‐albumin ratio (FAR), a new inflammatory biomarker, may provide better prognostic insights in patients with AIS than separate evaluation of fibrinogen or albumin. The objective of this investigation is to examine the correlation between FAR and 3‐month functional prognosis after intravenous thrombolysis (IVT) in AIS patients.


The retrospective study recruited AIS patients who received IVT from June 2014 to December 2021. The 3‐month functional prognosis was assessed using the Modified Rankin Scale (mRS). A mRS score of ≤2 indicated a good outcome, whereas a mRS score of >2 suggested a poor outcome.


A total of 591 AIS patients who underwent IVT were included and 147 patients (24.9 %) had a poor outcome. Among the 102 pairs of patients after propensity score matching, there was a significant association between FAR and 3‐month prognosis (adjusted OR, 1.19; 95% CI, 1.03–1.38; p = .020). The optimal FAR cutoff value was found to be 7.57, and even after stratifying patients based on this value, we still observed a significant correlation between high FAR level and poor outcome (adjusted OR, 2.08; 95% CI, 1.28–3.40; p = .003).


FAR may serve as a prospective biomarker of predicting 3‐month prognosis in AIS patients after IVT.
