Reducing Ischemic Stroke in Diabetes: The Role of GLP-1 RAs.

Key takeaways: Stroke is a significant cause of mortality worldwide, and diabetes is an independent risk factor for ischemic stroke occurrence and recurrence. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) lower the risk of ischemic stroke through beneficial effects on traditional stroke risk factors such as hyperglycemia, hypertension, and dyslipidemia. Primary care practitioners (PCPs) can play a substantial role in reducing ischemic stroke; studies have indicated that patients who have a PCP at the time of first stroke have a lower risk of stroke recurrence. Clinical practice guidelines recommend treating type 2 diabetes in patients with or at risk for cardiovascular (CV) disease with glucose-lowering agents with proven CV benefit, such as GLP-1 RAs and sodium-glucose cotransporter-2 (SGLT2) inhibitors. Based on meta-analyses of CV outcomes trials, GLP-1 RAs have a substantial and statistically significant benefit on ischemic stroke risk reduction, whereas SGLT2 inhibitors have a nonsignificant effect. The use of GLP-1 RAs, in addition to non-pharmacologic and pharmacologic management of traditional stroke risk factors, is a key component of complex therapy for ischemic stroke risk reduction.
