Abstract

Therapy with glucagon-like peptide 1 (GLP1) receptor agonists has raised great interest for its beneficial cardiovascular effects in preventing atherosclerosis and heart failure-related outcomes. However, while evidence about atherosclerosis consistently suggests a cardioprotective potential with class effect, controversies remain on its impact on heart failure. GLP1 receptor agonists appear to prevent hospitalization for new-onset heart failure and reduce symptoms in heart failure with preserved ejection fraction (as demonstrated by the recent STEP-HFpEF Trial). Still, GLP1 agonism has resulted in neutral or even harmful effects in patients with established heart failure with reduced ejection fraction (the LIVE trial). GLP1 receptor agonists benefit the cardiovascular system indirectly through their marked metabolic effects (improved weight management, glycemic control, blood pressure, systemic and tissue inflammation), while direct effects on the heart have been questioned. Nonetheless, weight loss alone achieved through GLP1 receptor agonists has failed in improving left ventricular functions. Tirzepatide is a dual agonist of GLP1 and glucose-dependent insulinotropic polypeptide, representing an innovative treatment option in diabetes with a major impact on weight loss and promising cardiovascular benefits. Whether this class of therapies is going to change the history of heart failure is an ongoing debate.

Core Tip: A growing body of evidence supports the potential cardioprotective properties of glucagon-like peptide 1 receptor agonists (GLP1-RAs) beyond glycemic control, especially in the context of cardiovascular disease. Although the effects of these drugs are consistent in reducing atherosclerosis-related diseases, there is an ongoing debate about the validity of the claim that GLP1-RAs have cardioprotective benefits in heart failure (HF)–a topic that sparks both enthusiasm and skepticism in the scientific and medical communities. Herein we provide a narrative review of the available evidence on the cardioprotective actions of GLP1-RAs in patients with HF, summarizing clinical findings and proposed mechanisms.
