GLP-1 receptor agonists may increase the risk of adverse heart failure outcomes in patients with heart failure and reduced left ventricular ejection fraction (LVEF), despite showing cardiovascular benefits in other populations.

If you have heart failure with reduced ejection fraction, GLP-1RAs might increase your risk of heart failure complications. Always inform your doctor about your full heart history before starting these medications.

ModerateQualifiesMEDIUM confidence
There are two main trials (FIGHT and LIVE trials) demonstrating that treatment with liraglutide increased the risk of adverse heart failure-associated outcomes in patients with heart failure and reduced LVEF [43-45].
