Metabolic Effects of the SGLT2 Inhibitor Dapagliflozin in Heart Failure Across the Spectrum of Ejection Fraction

Circ Heart FailPublished Secondary analysis of the DEFINE-HF and PRESERVED-HF randomised trials

Authors' conclusion

SGLT2is demonstrate common (fatty acid) and distinct (ketogenic) metabolic signatures across the LVEF spectrum.

Primary result

As reported in the abstract

Metabolite changes · 12 weeks
Increases in several acylcarnitines consistent across LVEF
Pinteraction>0.10
Ketogenic effect diminished at higher LVEF (3-hydroxybutyrate)
Pinteraction=0.01

Further findings

Ketosis (3-hydroxybutyrate >500 μM)

P = 0.03

Metabolite changes and heart failure (HF)-related outcomes

Increases in long-chain acylcarnitines and aromatic amino acids and decreases in branched-chain amino acids associated with worse HF-related outcomes, consistent across treatment and LVEF
