Abstract Objective: This study aimed to evaluate the association between stress hyperglycemia ratio (SHR) and poor functional outcomes at 90 days in patients with acute ischemic stroke (AIS). Methods: Retrospective collection of 1988 patients with AIS admitted to two hospitals in the Shenzhen area between January 2022 and March 2023. A total of 1255 patients with Fasting Blood-glucose (FBG) and hemoglobin A1c (HbA1C) values at admission were included in this analysis. SHR, measured by FBG/HbA1C, was evaluated as both a tri-categorical variable (Tertile 1: ≤0.83; Tertile 2: 0.84 -0.95; Tertile 3: ≥0.96). The outcome was poor functional outcomes (modified Rankin Scale mRS score 2-6) at 90 days. We performed univariate analysis, multiple equation regression analysis, stratified analysis, and interactive analysis. Results: Compared with patients in the lowest tertile of SHR, the highest tertile group had significantly lower odds of achieving poor functional outcomes (adjusted odds ratio, OR=2.84, 95% CI: 2.02-3.99, P<0.0001) at 90 days after adjusting for potential covariates. Similar results were observed after further adjustment for white blood cell count, neutrophil count, lymphocyte count, fasting blood glucose, stroke type, intravenous thrombolytic therapy, baseline Glasgow score, and baseline NIHSS score. Conclusion: Stress hyperglycemia ratio, as measured by the FBG/HbA1C, was associated with an increased odds of achieving poor functional outcomes in patients with AIS at 90 days.
