Efficacy of GLP-1 Receptor Agonists in Patients With Heart Failure and Mildly Reduced or Preserved Ejection Fraction: A Systematic Review and Meta-Analysis

Heart failure (HF) with mildly reduced or preserved ejection fraction (HFpEF) accounts for over half of cases of HF, with obesity playing a key role. Residual risk remains high despite available therapies. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown potential cardiometabolic benefits, but their role in HFpEF remains unclear.

A systematic review and meta-analysis of randomized controlled trials evaluating GLP-1RAs in HFpEF were conducted. Studies evaluating GLP-1RA in combination with glucose-dependent insulinotropic polypeptide (GIP) were also included. The analyzed outcomes included cardiovascular (CV) death, worsening HF events and their composite. Hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled by using a random-effects model.
