[Characteristics of the energy of electrostatic interaction of the formed elements of blood in experimental myocardial ischemia].

The diffusion and z-potentials of red cells of the blood outflowing from the zone of myocardial ischemia through the branch of the large cardiac vein were studied during acute period of experimental myocardial infarction. This enabled one to calculate the energy of electrostatic repulsion (EER) between blood constituents and to identify the factors exerting a significant effect on this value in acute experimental myocardial infarction induced in 20 dogs by ligation of the anterior interventricular branch of the left coronary artery. It was shown that the energetic state of the double electric lesion is the leading factor in the changed EER and in manifestation of the aggregation activity by the blood constituents. It was noted that the energetic potentials of red cells of the blood collected from the zone of myocardial ischemia show a statistically significant reduction.
