Objective The clinical significance of different glycemic parameters has been rarely investigated in ischemic stroke patients treated with intravenous tissue plasminogen activator (IV tPA). This study was aimed to investigate the association between different glycemic parameters and favorable functional outcome in patients treated with IV tPA. Methods Patients with ischemic stroke who received IV tPA therapy at our stroke center were retrospectively enrolled. Four glycemic parameters were collected including admission glucose, HbA1c, stress hyperglycemia ratio (SHR) and glycemic gap (GG). Additional information was also recorded including demographics, medical history, stroke severity, imaging measures and mRS score at discharge. We used 5 machine learning models to investigate the predictive value of glycemic parameters. Results Our study included 294 patients treated with IV tPA. SHR and GG were independently associated with favorable functional outcome (adjusted OR for SHR 0.03, 95% CI 0.01–0.72, P = 0.03; adjusted OR for GG 1.024, 95% CI 1.00–1.05, P = 0.04). Conclusion SHR and GG were associated with functional outcomes in acute ischemic stroke patients with intravenous thrombolysis.
