[Metabolism of fatty acids in the myocardium at various stages of development of acute cardiovascular insufficiency].

An experimental study in dogs, concerned with patterns of myocardial metabolism during the first and second phases of acute cardiovascular failure demonstrated a disjunction of mitochondrial oxidative phosphorylation where the supplied oxygen is consumed by processes unrelated to phosphorylation during the first phase of acute cardiovascular failure. In its second phase, the transport of oxygen and oxidation substrates to the heart is disrupted.
