Abstract

Obesity-related heart failure with preserved ejection fraction (HFpEF) has become a well-recognized HFpEF subphenotype. Targeting the unfavorable cardiometabolic profile may represent a rational treatment strategy. This study investigated semaglutide, a glucagon-like peptide-1 receptor agonist that induces significant weight loss in patients with obesity and/or type 2 diabetes mellitus and has been associated with improved cardiovascular outcomes. In a mouse model of HFpEF that was caused by advanced aging, female sex, obesity, and type 2 diabetes mellitus, semaglutide, compared with weight loss induced by pair feeding, improved the cardiometabolic profile, cardiac structure, and cardiac function. Mechanistically, transcriptomic, and proteomic analyses revealed that semaglutide improved left ventricular cytoskeleton function and endothelial function and restores protective immune responses in visceral adipose tissue. Strikingly, treatment with semaglutide induced a wide array of favorable cardiometabolic effects beyond the effect of weight loss by pair feeding. Glucagon-like peptide-1 receptor agonists may therefore represent an important novel therapeutic option for treatment of HFpEF, especially when obesity-related.

TL;DR

In aged female mice with a multifactorial HFpEF-like phenotype, semaglutide improved cardiac function and structure beyond the effects of pair-fed weight loss. The benefits were linked to endothelial GLP-1 receptor expression and anti-inflammatory/antioxidant pathways, supporting ongoing clinical trials in obesity-related HFpEF.

Key findings

  • Semaglutide and pair feeding (PF) produced similar weight loss, mainly from fat mass reduction over 4 weeks (19.4–6.2 g for semaglutide; 19.8–8.3 g for PF). Semaglutide reduced food intake by ∼60% in week 1, ∼30% in week 2, and ∼10% in weeks 3–4.
  • Semaglutide, but not PF, improved glycemic control (fasting glucose and oral glucose tolerance test AUC) and exercise capacity. It also improved global longitudinal strain and reverse peak longitudinal strain rate, while LVEF was preserved in all groups with no significant differences.
  • Semaglutide reduced LV hypertrophy (LV weight/tibia, cardiomyocyte size, LV wall thickness), atrial and lung weights, fibrosis, and mRNA markers including ANP, Col1a1, Col3a1, TIMP-1, IL-6, galectin-3, and GDF-15. Intrinsic cardiomyocyte stiffness (Fpassive) was not affected by any intervention.
  • Omics analyses showed GLP-1 receptor mainly in endothelial cells; semaglutide enriched endothelial actin/ATP/metabolic and cardiomyocyte contraction/mitochondrial/anti-apoptotic pathways. Plasma proteomics identified 240 semaglutide-associated proteins versus 116 with PF, with antioxidant/oxidative-stress pathways; VAT showed up-regulated T-cell/interferon-γ and down-regulated extracellular matrix pathways.

Methods

  • Aged female C57BL6/J mice (18–22 months) were fed high-fat diet (HFD) for 12 weeks; after 8 weeks, angiotensin-II (1.25 mg/kg/d) was infused via osmotic minipump. Control mice (n = 10) received low-fat diet.
  • After pump implantation, HFD mice received semaglutide (n = 12; uptitrated over 5 days to 9 nmol/kg/d, then continued 23 days), vehicle (n = 16), or pair feeding (n = 8) for the final 4 weeks.
  • Outcomes included echocardiography, oral glucose tolerance test, body composition, voluntary wheel running, histology, qPCR, passive force measurements, plasma ketones, VAT RNA sequencing, LV single-nucleus RNA sequencing, and LV/plasma LC-MS/MS proteomics. Statistical comparisons used Kruskal-Wallis with Dunn tests; P < 0.05 was significant.

Limitations

  • The paper states the multifactorial mouse model does not represent the entire HFpEF spectrum, used only aged female mice, and cannot determine whether semaglutide prevents incident HFpEF or attenuates prevalent HFpEF because treatment began after 8 weeks of HFD and at the start of ANGII infusion. The role of endothelial GLP-1 receptor requires lengthy follow-up studies in old animals.
  • Evident from the text: omics analyses used n = 6 per group, and the study is preclinical, so it cannot establish clinical outcomes or causality in patients.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • STEP 1 results are cited to an unrelated reference

    Minor

    The discussion attributes the stated STEP 1 result to reference 7, but reference 7 is the I-PRESERVE trial of irbesartan in heart failure.

  • Echocardiography timing differs between methods and figure caption

    Minor

    The methods place echocardiography three days before sacrifice, whereas the Figure 1 caption places it one day before sacrifice.

  • STEP-HFpEF studies are cited to the SELECT reference

    Minor

    The conclusions attach reference 83 to the STEP-HFpEF studies, but reference 83 is explicitly about SELECT.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
