Brief Summary
Starvation and metabolic stress increase circulating ketone bodies, potentially providing the heart with an alternative oxidative fuel. Hyperketonemia reduces myocardial fatty acid consumption. It is unclear whether this is due to inhibited peripheral lipolysis or diminished uptake per se. Aim: To test whether infusion of 3-hydroxybutyrate (BHB) inhibits myocardial glucose and fatty acid uptake. Methods: Randomized, single blinded, cross-over interventional study in 8 healthy volunteers. Myocardial glucose and fatty acid metabolism studied by 11C-palmitate and 18F-FDG PET/CT. Experimental elevation of circulating ketone bodies by infusion of β-hydroxy-β-methylbutyrate.
