Abstract 50: Sodium-Glucose Cotransporter 2 Inhibitors Use in Diabetic Patients With Acute Ischemic Stroke is Linked to Favorable Neurological Outcomes

Abstract

Background: The benefits of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in acute ischemic stroke (AIS) have been demonstrated preclinically. Here, we evaluated the neurological effects of SGLT2i use after stroke in patients with diabetes and AIS. Methods: Using a prospective stroke registry, we reviewed consecutive diabetic patients with AIS. Patients with and without SGLT2i use were 1:4 propensity score-matched for clinical variables. Clinical outcomes, including early neurological deterioration (END) during admission, National Institutes of Health Stroke Scale (NIHSS) score at discharge, and modified Rankin Scale (mRS) scores at discharge and at 3 months, were compared. The impact of SGLT2i on metabolic activity of various organs was examined in another cohort using 18 F-fluorodeoxyglucose positron emission tomography post-stroke. Results: Among the 820 eligible patients, 90 (11.0%) were prescribed SGLT2i on admission, and 76 continued the prescription at discharge. Seventy-four patients with and 266 patients without SGLT2i use were propensity score-matched and analyzed. SGLT2i did not increase the END risk (adjusted odds ratio [aOR] 0.48, 95% confidence interval [CI] 0.20-1.19). There was no significant difference in clinical outcomes at discharge between the two groups (NIHSS: B [standard error] -1.321 [0.952], p=0.17; mRS: aOR for favorable mRS 1.47, 95% CI 0.93-2.32). SGLT2i demonstrated significant improvement in the 3-month mRS (aOR 1.73, 95% CI 1.10-2.74). The positron emission tomography cohort showed that SGLT2i prescription was associated with elevated brown and subcutaneous adipose tissue metabolism. Conclusions: SGLT2i may be a priority for diabetic patients with AIS because of its potential benefits on long-term outcomes.
