Abstract WP13: Value Of Stress Hyperglycemia Ratio In Predicting The Prognosis Of Patients With Acute Ischemic Stroke:a Subgroup Analysis Of The Rescue Bt Clinical Trial

Objective: This study aimed to evaluate the correlation between the stress hyperglycemia and clinical outcomes after large vessel occlusion stroke (LVO) at 90 days. Methods: The RESCUE BT trial was a multicenter, randomized, double-blind, placebo-controlled clinical trial, consisting of 948 patients from 55 centers in China. In this subgroup study, 542 consecutive stroke patients with glucose or glycated hemoglobin values were included. Stress hyperglycemia was evaluated both as a tri-categorical variable (≤1.07 vs 1.08-1.29 vs ≥1.30) and a continuous variable. The primary outcome was favorable functional outcome (modified Rankin Scale [mRS] ≤ 2) at 90 days. The secondary outcome contained excellent functional outcome (modified Rankin Scale [mRS] ≤ 1) and safety outcomes such as 90-day mortality and intracranial hemorrhage. Results: 542 patients were included. Compared to patients with the lowest tertiles of stress hyperglycemia, calculated as glucose/GA ratio, the highest tertiles of stress hyperglycemia was obviously associated with a higher rate of poor functional outcome at 90-day (modified Rankin Scale [mRS] score 3-6) after adjusted for potential covariates (adjusted hazard ratio, 0.44; 95% confidence interval, 0.28-0.69, P < 0.001). This result was also consistent in the excellent clinical outcome of 90-day mRS score 2-6 (adjusted hazard ratio, 0.48; 95% confidence interval, 0.29-0.79, P =0.004). Conclusion: In patients with acute ischemic stroke, lower stress hyperglycemia, as measured by glucose/GA ratio, was more likely to have favorable outcome at 90-day.
