GLP-1 receptor agonists beyond glycemic control: integrated cardio-renal-metabolic protection across the cardiovascular kidney metabolic continuum
Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have undergone a fundamental repositioning, once defined by their glycemic effects, they are now established as multi-organ protective agents operating across the cardiovascular-kidney-metabolic (CKM) continuum with benefits that extend substantially beyond glucose lowering, though the precise contribution of glycemic versus non-glycemic mechanisms varies by outcome and population. Major cardiovascular and renal outcome trials; LEADER, REWIND, AMPLITUDE-O, SELECT, FLOW, and SOUL, collectively demonstrate 13-20% reductions in major adverse cardiovascular events (MACE) and meaningful attenuation of chronic kidney disease (CKD) progression in both diabetic and non-diabetic populations. Exploratory mediation analyses from SELECT suggest that a substantial fraction of cardiovascular benefit is not explained by measured cardiometabolic risk factor changes, a finding that is hypothesis-generating and informs ongoing mechanistic investigation. This narrative review synthesizes mechanistic and clinical evidence for integrated GLP-1RA CKM protection, evaluates combination strategies with Sodium-Glucose Cotransporter 2 (SGLT2) inhibitors, and confronts the implementation gap that separates extraordinary trial efficacy from modest real-world uptake, with rigorous distinction between RCT-level evidence, observational findings, and mechanistic hypotheses. We propose a CKM Disease-Modification Framework as a conceptual scaffold for…
