[Glucagon-like peptide-1 agonists and heart failure]

Developed to treat type 2 diabetes, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been associated with a reduced risk of cardiovascular events in high-risk patients with diabetes, and later in obese patients with cardiovascular disease without diabetes. More recently, semaglutide and tirzepatide have demonstrated benefits in obese patients with heart failure (HF) with preserved or mildly reduced ejection fraction, including fewer HF hospitalisations and improvements in symptoms and functional capacity. Data remain limited in heart failure with reduced ejection fraction. This article summarises current evidence on these therapies, particularly in HF, and provides practical guidance for their prescription and follow-up.
