[The body oxygen allowance in myocardial infarct patients with progressive forms of acute circulatory failure]

Oxygen supply of the body was studied in 172 patients with macrofocal myocardial infarction with a varying course of acute circulatory insufficiency. It was found that most patients with acute circulatory insufficiency developing during onset of the disease showed latent cardiac insufficiency that can be detected determination of the coefficient of oxygen transport function of the left ventricle. These patients also showed a pronounced shift of oxyhemoglobin dissociation curve to the right and an increase of the peripheral blood flow.
