GLP-1 Receptor Agonists in Heart Failure: A Systematic Review and Meta-analysis with Phenotype-Specific Effects and Dual Analytical Frameworks

Background

Although glucagon-like peptide-1 receptor agonists (GLP-1 RAs) reduce cardiovascular risk in patients with type 2 diabetes mellitus (T2D), evidence in heart failure (HF) has expanded across diverse trial populations and HF phenotypes but remains fragmented. We therefore performed an integrated systematic review and meta-analysis to evaluate the effects of GLP-1 RAs across the spectrum of HF using complementary trial-level and phenotype-based analyses.
