Background Clinical evidence of the potential influence of stress hyperglycemia ratio (SHR) for patients with large ischemic stroke whether or not receiving endovascular therapy is not clear. Methods This study was a subanalysis of a prospective, multicenter registry, and included 745 patients with large ischemic stroke across 38 centers in China. A total of 427 patients were included in this study, with 285 received endovascular therapy (EVT) and 142 received standard medical therapy (SMT). SHR was defined as glucose (mmol/L)/(1.59 × HbA1C)–2.59. The primary outcome was a moderate neurological outcome (modified Rankin Scale (mRS) score ≤3) at 90 days. Results A significant interaction was observed between SHR and whether received EVT (p=0.017). Among patients who received EVT (adjusted OR (aOR) 0.46; 95% CI 0.23 to 0.92; p=0.029), patients in the highest tertile of SHR were significantly less likely to achieve a moderate neurological outcome at 90 days compared with those in the lowest tertile. However, this association was not observed in patients receiving SMT (aOR 2.46; 95% CI 0.74 to 8.21; p=0.142). EVT patients with higher SHR had a significantly higher incidence of symptomatic intracranial hemorrhage compared with lower SHR (aOR 3.29; 95% CI 1.08 to 10.06; p=0.036), while such an association was not observed in the SMT group (aOR 1.52; 95% CI 0.56 to 4.12; p=0.410). Conclusions In patients with large ischemic stroke treated with EVT, SHR is associated with a reduced likelihood of achieving a moderate neurological outcome, as well as an increased risk of symptomatic intracranial hemorrhage.
