Glucagon-Like Peptide-1 Receptor Agonists in Obese Heart Failure With Preserved Ejection Fraction.

TL;DR

Among patients with obesity, type 2 diabetes, and heart failure with preserved ejection fraction in the Veterans Affairs system, GLP-1RA initiation was associated with a lower incidence of death or heart failure hospitalization compared with DPP4 inhibitors/sulfonylureas.

Key Findings

GLP-1 receptor agonist initiation was associated with a lower risk of all-cause mortality or heart failure hospitalization compared with DPP4 inhibitors/sulfonylureas.

  • Adjusted hazard ratio, 0.78 (95% CI, 0.64-0.95), P=0.01.
  • Median follow-up was 1.5 years.
  • Inverse probability of treatment weighting based on the propensity score was used to balance baseline characteristics.

Only a small fraction of the screened HFpEF population with type 2 diabetes and obesity met the inclusion criteria for the new-user, active-comparator analysis.

  • Among 179,288 patients with type 2 diabetes, obesity, and HFpEF, 1024 GLP-1RA users and 796 DPP4 inhibitor/sulfonylurea users met inclusion criteria.
  • Patients were identified in the national VA Health System (170 US hospitals) with a validated diagnostic algorithm for HFpEF and BMI ≥30 kg/m2.
  • Exposure was initiation between January 1, 2015 and December 31, 2021.

Weight loss was modestly greater with GLP-1RAs than with DPP4 inhibitors/sulfonylureas.

  • Weight change was -12.9% with GLP-1RAs versus -10.1% with DPP4 inhibitors/sulfonylureas.

The study used a nationwide multicenter new-user, active-comparator cohort design in the Veterans Affairs Health System.

  • Adults with type 2 diabetes between January 1, 2000 and December 31, 2021 were identified from centralized electronic health records.
  • The primary outcome was time to all-cause mortality or heart failure hospitalization.
  • The comparator was DPP4 inhibitors or sulfonylureas rather than no treatment.

What This Means

This study looked at U.S. veterans who had type 2 diabetes, obesity, and a form of heart failure called heart failure with preserved ejection fraction (HFpEF). It compared those who started a GLP-1 receptor agonist (a class of diabetes and weight-loss drugs) with those who started other oral diabetes drugs (DPP4 inhibitors or sulfonylureas). Of more than 179,000 patients with these conditions, 1,820 met the criteria for comparison: 1,024 started a GLP-1 drug and 796 started another drug. Over a median follow-up of about 1.5 years, people who started a GLP-1 drug had about a 22% lower risk of dying or being hospitalized for heart failure (adjusted hazard ratio 0.78). Weight loss was somewhat greater with GLP-1 drugs (about 12.9% versus 10.1%), but the difference was modest. This research suggests GLP-1 drugs may be linked to better outcomes in this group of patients. However, this was an observational study, not a randomized trial, so it cannot prove that the drugs caused the benefit. The patients were veterans, and the follow-up was relatively short, so the results may not apply to everyone.
