Abstract 4134637: Impact of Glucagon-Like Peptide-1 Agonists on Cardiovascular Outcomes in Chronic Kidney Disease Stage 5: A Propensity Score-Matched Analysis

Background: Patients with chronic kidney disease stage 5 (CKD-5) face heightened risks of cardiovascular (CV) complications and mortality. Glucagon-like peptide-1 agonists (GLP-1a), primarily used in type 2 diabetes, are being investigated for potential CV benefits in this population. This study aims to evaluate the impact of GLP-1a treatment on CV outcomes and survival among CKD-5 patients. Methods: This retrospective cohort study utilized data of adult patients diagnosed with CKD-5 between January 2014 and August 2023 from the TriNetX global research network. A propensity score matching analysis of those treated with GLP-1a for at least six months versus those never exposed to GLP-1a therapy was conducted. Results: Our analysis showed significantly reduced odds for the composite primary outcome of acute myocardial infarction (AMI), stroke, and mortality (OR = 0.66, 95% CI: 0.57-0.78, p<0.001), and other CV outcomes such as cardiac arrest, hypertensive crisis, and hypertensive urgency, among the GLP-1a cohort compared with the non-GLP-1a cohort. Kaplan-Meier survival analysis revealed a significantly higher five-year incidence-free probability for the composite primary outcome (63.5% vs. 50.5%, p<0.001) and for other CV outcomes such as hypertensive events, AMI, cardiac arrest, and hemorrhagic stroke for the GLP-1a cohort. Conclusion: The study suggests that GLP-1a therapy in CKD 5 patients may confer certain CV benefits. Further investigations are warranted to elucidate the underlying mechanisms and confirm the therapeutic efficacy of GLP-1a in this patient population.
