Official title
Feasibility and Safety of Prolonged Nasogastric Administration of Ketones in Decompensated Heart Failure
Overview
This study will evaluate the feasibility and safety of achieving therapeutic concentrations of beta-hydroxybutyrate using continuous infusion of D-beta-hydroxybutyrate monoester administered via a nasogastric tube in patients with acutely decompensated heart failure with reduced left ventricular ejection fraction.
Detailed description
Adult patients with left ventricular ejection fraction (LVEF) \<35% admitted to the intensive care unit for acutely decompensated heart failure with low cardiac output syndrome or cardiogenic shock will receive a continuous infusion of D-3-hydroxybutyrate (3-OHB) monoester via a nasogastric tube for 36 hours. The infusion rate will be iteratively adjusted to achieve an arterial blood concentration of 3-OHB of 2-3.5 mmol/L. Arterial blood concentrations of 3-OHB will be measured every 1-3 hours using point-of-care testing. The primary endpoint will be the proportion of time within the target concentration range. Secondary safety endpoints will include worsening of liver function not attributable to hemodynamic deterioration, occurrence of cardiac arrhythmias, and gastrointestinal tolerance of the infusion.
Interventions
- Dietary supplement Ketone Monoester (KE)
Continous infusion of a commercially available ketone monoester via nasogastric tube.
Primary outcome measures
- Proportion of time within the target concentration range [Time frame: 36 hours]
Secondary outcome measures (2)
- Worsening of liver function [Time frame: During 72 hours within from start of the study intervention]
- GIT tolerance [Time frame: During 36 hours of the study]
