Modulation of Circulating Levels of the Ketone Body 3-hydroxybutyrate in Patients With Type 2 Diabetes and Heart Failure With Preserved Ejection Fraction: Metabolic Effects. (KETO-HFpEF-Metabolic)

Heart failure (HF) is among the most common causes of death in patients with type 2 diabetes (T2D). Ketones, 3-hydroxybutyrate (3-OHB), have shown to have beneficial effects in patients with hearth failure with reduced ejection fraction. However, this have never been investigated in patients with heart failure with preserved ejection fraction (HFpEF).

In this study we would like to investigate the effect of 14 days modulation of circulating ketone body levels on whole body and skeletal metabolism in patients with HFpEF and T2D.
