Prediabetes and diabetes mellitus type II after ischemic stroke

Abstract

Introduction: The progression of diabetes status in post-stroke patients remains under-investigated, particularly regarding new treatments for type II diabetes mellitus (DM II), like glucagon-like peptide 1 receptor agonists (GLP-1-RA) and sodium-glucose co-transporter-2 (SGLT-2) inhibitors, which have not been studied in the post-stroke setting. Patients and methods: Eight hundred eighty-four consecutive ischemic stroke patients recruited to our prospective STROKE-CARD Registry were assessed concerning their glycemic status at baseline (normoglycemia, prediabetes, DM II) and change over time within 1 year follow-up. Multivariate logistic regression was performed to identify factors associated with transitioning from normoglycemia to prediabetes or DM II. Additionally, we reviewed ongoing clinical trials for GLP-1-RA and SGLT-2 inhibitors in the context of acute ischemic stroke. Results: At baseline, 44.6% (n = 394) of individuals had normoglycemia, 33.9% (n = 300) were prediabetic, and 21.5% had DM II (n = 190). After 1 year, normoglycemia decreased by 12.1 percentage points (n = 107), whereas prediabetes and DM II increased by 10.2 percentage (n = 90) points and 1.9 percentage points (n = 17), respectively. Statin therapy was the only significant risk factor for progression. 23.4% (n = 207) of our cohort would have met eligibility criteria for a recent trial on semaglutide in obese non-diabetics with prior cardiovascular disease. However, only one ongoing trial aims at evaluating short-term cardiovascular risk reduction in stroke patients. Discussion: GPrediabetes and DM II are frequent in ischemic stroke patients. Even within an intensified post-stroke disease management setting, a considerable amount of stroke survivors convert to prediabetes or DM II within the first year. Our results demonstrate a notable proportion of patients qualifying inclusion in studies examining the efficacy of GLP-1-RA agonists and SGLT-2 inhibitors in secondary prevention. Conclusion: Given the high prevalence and progression of prediabetes and DM II in stroke survivors, there is a need for clinical trials evaluating the use of GLP-1-RA and SGLT-2 inhibitors in this population.
