Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Supplementation of exogenous ketones

Control group

Arm Description

Exogeneous ketones will be administered orally using monoester 3-OHB concentrate without added salts (25g 3-OHB in 65ml H.V.M.N Ketone Ester, H.V.M.N, USA or equivalent). The drink will be administered over 10 mins every 3 hours, 3 times in a row.

The patients will receive a placebo drink (drinking water) of equivalent volume (3x 65ml)

Outcomes

Primary Outcome Measures

Maximum change of stroke volume index
Maximum change of stroke volume index (ml/m2) between baseline and hour 1 - 3
Maximum change of cardiac index
Maximum change of cardiac index (L/m2) between baseline and hour 1 - 3
Change of mean stroke volume index
Difference between baseline stroke volume index and mean stroke volume index (ml/m2) during the study protocol
Change of mean cardiac index
Difference between baseline cardiac index (L/m2) and mean cardiac index during the study protocol

Secondary Outcome Measures

Change in patient/symptoms
Change in patient-referred symptoms by visual-analog scale (1=unbearable dyspnea, 10=no symptoms)

5. Study Description

Brief Summary
This study will evaluate whether supplementation of exogenous ketones in patients with severe left ventricular dysfunction and acutely decompensated heart failure requiring inotropic therapy would improve the patient's hemodynamics and symptoms.
Detailed Description
The study will include patients with acutely decompensated chronic heart failure requiring inotropic therapy for the syndrome of low cardiac output. While being on the inotropic therapy, the patients will be randomized to oral supplementation of exogenous ketones vs. placebo, which will be repeatedly administered over 9 hours. The patients will undergo continuous invasive hemodynamic monitoring by pulmonary artery catheter, repeated laboratory assessment, and repeated assessment of the severity of symptoms for 24 hours. Exogenous ketones will be administered orally using monoester 3-OHB concentrate without added salts (25g 3-OHB in 65ml H.V.M.N Ketone Ester, H.V.M.N, USA or equivalent). The drink will be administered over 10 mins every 3 hours, 3 times in a row (hour 0, 3, 6). All patients with K<3.7 mmol/l will receive a continuous infusion of 7.5% potassium until reach target K levels of 4.0-4.9 mmol /l. Glycemia will be controlled as needed by insulin and dextrose to maintain glucose concentration of 4 - 12 mmol/l All patients will receive standard treatment of acute heart failure, including intravenous diuretics and inotropic therapy. The recommended inotropic therapy will include milrinone 0.5 ug/kg/min, levosimendan 0.1 ug/kg/min up to 25mg without initial bolus, or dobutamine 0.5 ug/kg/min in patients without chronic therapy with beta-blockers. The severity of symptoms will be self-reported by the patient using 1-10 visual analog scale. Workflow: Hemodynamic assessment, assessment of ketones concentration: 1-3h before randomization, 0-9h hourly, 16-24h (next morning) Biochemical assessment (renal function, liver enzymes, BNP, hs-TnT) 0h, 9h, 16-24h Assessment of symptoms and Scv02: 0h, 1h, 3h, 9h, 16-24h Statistical methods: Each study arm will include 12 patients. The study size was estimated to have power of (1 - beta) of 0.8 and alpha of 5% for between-group comparison of changes in cardiac index and stroke volume index by ANOVA and for comparison of the changes in cardiac index and stroke volume index by paired t-tests.
