Peculiarities of the Functional State of Mitochondria of Peripheral Blood Leukocytes in Patients with Acute Myocardial Infarction.

We studied the rate of oxygen consumption by mitochondria isolated from peripheral blood leukocytes of patients with acute myocardial infarction and healthy volunteers. It was found that leukocyte mitochondria in patients with acute myocardial infarction were characterized by significantly lower rate of oxygen consumption and lower level of coupling of oxidation and phosphorylation processes in comparison with mitochondria from healthy volunteers.
