Mitochondrial bioenergetics links inflammation and cardiac contractility in endotoxemia.

There is current awareness about the central role of mitochondrial dysfunction in the development of cardiac dysfunction in systemic inflammatory syndromes, especially in sepsis and endotoxemia. The aim of this work was to elucidate the mechanism that governs the link between the severity of the systemic inflammatory insult and mitochondrial function, analysing the consequences on heart function, particularly in cardiac contractile state. Female Sprague-Dawley rats were subjected to low-grade endotoxemia (i.
