Brief summary
Does oral intake of exogenous ketone salt improve heart function measured by cardiac MRI in heart failure compared to oral intake of a carbohydrate placebo?
Detailed description
This study will help to quantify heart and kidney ketone uptake with or without an exogenous ketone salt in heart failure condition. Participants will have 2 different cardiac MRI to perform: 1. Fasting with exogenous ketone salt supplement 2. Fasting with exogenous carbohydrate supplement
Interventions
Dietary Supplement: Fasting water and with exogenous ketone salt supplement. Participants will have to take 1 doses of supplement 30 minutes before the scan.
Dietary Supplement: Fasting water and with exogenous carbohydrate supplement. Participants will have to take 1 doses of supplement 30 minutes before the scan.
