Acute heart failure is a potentially life-threatening condition, reaching mortality rates of up to 50% in advanced cases. The investigators have shown that infusion of ketone bodies increase cardiac output by 40% in stabile patients with chronic heart failure. However, there are no data showing the effects of ketone on patients with acute heart failure


To investigate the effect of ketone supplementation in patients with acute heart failure and cardiogenic shock, using two different types of oral ketone supplements.


The investigators will conduct four randomized placebo-controlled studies, to investigate the hemodynamic effect of exogenous ketones in acute heart failure and cardiogenic shock.


The present study will determine the potential beneficial effects of ketone supplements in patients with acute heart failure.
