Dapagliflozin reduces epicardial adipose tissue in patients with heart failure and type 2 diabetes.
Background: Epicardial adipose tissue (EAT) has a contributory role in the progression of heart failure. We tested whether dapagliflozin reduces EAT in adults with type 2 diabetes (T2D) and heart failure and explored links with systemic inflammation and cardiac structure.
Methods: This analysis is based on pooled data from two phase 2, single-centre, double-blind, placebo-controlled randomised trials (REFORM and DAPA-LVH) conducted in Scotland. Exactly 122 participants with T2D and stage B or C heart failure were randomised to dapagliflozin 10 mg once daily or placebo for 12 months. Cardiac magnetic resonance imaging (CMR) was used to assess EAT. At baseline and follow-up, the inflammatory markers TNF, IL-1, IL-6, IL-10, and CRP were measured.
Results: At baseline, obesity was common (75% with BMI ≥30 kg/m2) and heart-failure phenotypes were balanced (HFpEF 51%, HFrEF 49%). After 12 months, dapagliflozin significantly reduced EAT independently of changes in BMI (-1.16 ± 0.18 vs. +0.36 ± 0.19 cm2, p < 0.001), BMI (-1.17 ± 0.16 vs. -0.18 ± 0.17 kg/m2, p < 0.001), and left ventricular mass (-3.53 ± 1.77 vs. +1.57 ± 1.83 g, p = 0.048) compared with placebo.
Conclusion: Dapagliflozin shrinks EAT and LV mass independently of BMI in T2D patients with stage B/C heart failure, supporting EAT as a modifiable target of SGLT2 inhibition. The absence of parallel changes in systemic inflammation suggests primarily local mechanisms.
期刊介绍：
Diabetes, Obesity and Metabolism is primarily a journal of clinical and experimental pharmacology and therapeutics covering the interrelated areas of diabetes, obesity and metabolism. The journal prioritises high-quality original research that reports on the effects of new or existing therapies, including dietary, exercise and lifestyle (non-pharmacological) interventions, in any aspect of metabolic and endocrine disease, either in humans or animal and cellular systems. ‘Metabolism’ may relate to lipids, bone and drug metabolism, or broader aspects of endocrine dysfunction. Preclinical pharmacology, pharmacokinetic studies, meta-analyses and those addressing drug safety and tolerability are also highly suitable for publication in this journal. Original research may be published as a main paper or as a research letter.
