Pharmacological treatment for patients with obesity and heart failure: Focus on glucagon-like peptide-1 receptor agonists. European Journal of Heart Failure expert consensus document

There is growing clinical interest in strategies for improving clinical outcomes in patients with heart failure (HF) and obesity. The development of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and of the dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA has expanded therapeutic options for this population. This expert consensus provides a comprehensive and pragmatic framework for the use of GLP-1 RAs and GIP/GLP-1 RA in patients with HF, focusing on clinical integration, patient selection, safety, and tolerability. We review the evidence supporting their use in patients with HF with preserved ejection fraction (HFpEF), where clinical trials have demonstrated meaningful reductions in body weight alongside improvements in health status and exercise capacity. Whether these effects translate into fewer HF events or lower cardiovascular mortality remains uncertain, as current evidence is limited to two small trials with few observed events. In contrast, data regarding the efficacy and safety of these drugs in HF with reduced ejection fraction are scarce, with dedicated outcome trials yet to be launched. Finally, this document highlights knowledge gaps and outlines future research directions in this field.
