What is this paper about
This paper shows that GLP-1 receptor agonists are no longer just diabetes or weight-loss drugs: across a broad evidence base, they emerge as major cardiometabolic therapies linked to lower cardiovascular risk through both metabolic and direct vascular effects. The full paper is worth reading because it shows where this benefit is strongest, where the evidence is still mixed, and why the biggest gap may now lie not in efficacy, but in getting these drugs to the patients who need them most.

Abstract: This review aims to systematically synthesize the evidence from the provided literature summary regarding the effects of glucagon-like peptide-1 (GLP-1) receptor agonists on cardiovascular outcomes, mechanisms of action, and their role in the management of cardiometabolic disease. The review utilises 952 original studies with 24318087 total participants (naïve ΣN). This systematic review confirms that glucagon-like peptide-1 receptor agonists have transformed the management of cardiometabolic disease, offering robust and consistent cardiovascular protection. The evidence demonstrates a significant reduction in major adverse cardiovascular events, with a median risk reduction of approximately 14%, driven by a confluence of mechanisms including improved metabolic parameters, anti-inflammatory effects, and direct vascular benefits. Key themes emerging from the literature include the profound synergistic effects of combination therapy with SGLT2 inhibitors, the expanding efficacy in non-diabetic populations, and the critical issue of clinical inertia and underutilization in high-risk groups. A primary limitation is the heterogeneity of the evidence base, which includes numerous observational studies alongside randomized trials. A crucial research implication is the need for implementation science studies to bridge the gap between strong evidence and suboptimal clinical uptake, ensuring that these life-saving therapies reach the millions of eligible patients who stand to benefit.
