Background Oral treatment with the exogenous ketone body 3‐hydroxybutyrate improves cardiac function in patients with heart failure with reduced ejection fraction, but ketosis is limited to 3 to 4 hours. Treatment with (R)‐1,3‐butanediol (BD) provides prolonged ketosis in healthy controls, but the hemodynamic and metabolic profile is unexplored in...

Background Cardiogenic shock (CS) presents a medical challenge with limited treatment options. Positive end-expiratory pressure (PEEP) during mechanical ventilation has been linked with clinical benefits in patients with CS. We investigated if increasing PEEP levels could unload the left ventricle (LV) in CS in a large animal model of LV-CS. Metho...

Background: The naturally occurring metabolite lactate has traditionally been considered as a waste product of anaerobic metabolism whose production was confined to hypoxic states. However, more evidence supports that lactate is a preferred oxidative substrate for the myocardium when present in high plasma levels. Small-scale clinical studies have...

Background: Cardiogenic shock (CS) is a life-threatening disease with limited evidence-based treatment options. Treatment with the ketone body 3-hydroxybutyrate (3-OHB) induces favorable hemodynamic effects in patients with heart failure and CS. It increases cardiac output (CO) and left ventricular (LV) ejection fraction (LVEF) while reducing cardi...

Background Lactate is traditionally recognized as a by-product of anaerobic metabolism. However, lactate is a preferred oxidative substrate for stressed myocardium. Exogenous lactate infusion increases cardiac output (CO). The exact mechanism underlying this mechanism has yet to be elucidated. The aim of this study was to investigate the cardiovasc...

Background Lactate is traditionally acknowledged as a by-product of anaerobic glucose metabolism. Recently, however, lactate has been proven to be a preferred oxidative substrate for stressed myocardium. Studies have shown that exogenous lactate infusion provides beneficial hemodynamic effects including increased cardiac output (CO). Nevertheless,...

Extrachromosomal circular DNA (eccDNA) is a closed-circle, nuclear, nonplasmid DNA molecule found in all tested eukaryotes. eccDNA plays important roles in cancer pathogenesis, evolution of tumor heterogeneity, and therapeutic resistance. It is known under many names, including very large cancer-specific circular extrachromosomal DNA (ecDNA), which...
