GLP-1 Receptor Agonists Among Patients With Overweight or Obesity, Diabetes, and HFpEF on SGLT2 Inhibitors
Background: Although the use of glucagon-like peptide-1 receptor agonist (GLP-1 RA) in patients with obesity and heart failure with preserved ejection fraction (HFpEF) has demonstrated improvement in cardiovascular outcomes, the incremental benefits of GLP-1 RA for patients already on sodium-glucose cotransporter 2 inhibitors (SGLT2is) remain underexplored.
Objectives: This study aimed to assess the incremental benefits of GLP-1 RA in patients with type 2 diabetes mellitus, overweight/obesity, and HFpEF receiving SGLT2i therapy.
Methods: The authors conducted a retrospective cohort study using the TriNetX research database including patients ≥18 years with type 2 diabetes mellitus, body mass index ≥27 kg/m2, and HFpEF on SGLT2i. Two cohorts were created based on GLP-1 RA prescription. The outcomes were heart failure exacerbation, all-cause emergency department visits/hospitalizations among others over a 12-month period.
Results: A total of 7,044 patients remained in each cohort after propensity score matching. There was a significantly lower risk of heart failure exacerbations, all-cause emergency department visits/hospitalizations, new-onset atrial arrhythmias, new-onset acute kidney injury, and pulmonary hypertension in the GLP-1 RA plus SGLT2i cohort compared with the SGLT2i-only cohort. The associated benefits persisted across different body mass indexes and ejection fractions as well as in patients with elevated natriuretic peptide. The risk of diabetic retinopathy was higher in the combination therapy group than with SGLT2i-only use.
Conclusions: GLP-1 RA, in addition to SGLT2i, was associated with a significantly lower risk of heart failure hospitalizations in this patient population, suggesting a potential incremental benefit. This highlights the need for prospective studies to confirm the clinical benefits.
