[Nonspecific immunity factors and elimination of circulating immune complexes in patients with myocardial infarct in the 1st phase of rehabilitation]. / Nespetsificheskie faktory immuniteta i éliminatsiia tsirkuliruiushchikh immunnykh kompleksov u bol'nykh infarktom miokarda v pervoi faze reabilitatsii.

A considerable increment of humoral immunity parameters was demonstrated during the 3d-5th week after the onset of myocardial infarction (MI). The levels of IgG and IgE were increased, and those of circulating immune complexes (CIC), decreased significantly in patients with their first diagnosed infarction, as compared to those with repeated MI. Patients with repeated MI showed significantly reduced blood C3c, C4 and the phagocyte index in the presence of high blood levels of CIC and C-reactive protein, as compared to patients with primary infarction. The results are indicative of a considerable activation of the complement and the phagocytic system and CIC elimination in patients with their first MI diagnosis, and the absence of such a stimulation in repeated MI cases.
