[Changes of endotoxin concentration in blood serum in patients with uncomplicated acute myocardial Q-infarction]

The effectiveness of acute myocardial infarction (AMI) treatment does not correspond to high material costs for the study of its pathogenesis and development of new drugs. This circumstance gives the grounds to assume existence of nowadays unknown mechanisms of emergence and development of this disease. High probability of participation of endotoxin (ET) in the pathogenesis of AMI was theoretically proved by us for more than a quarter of the century ago, but it's clinical evidence to date is not found yet. As a result of the study a significant increase of endotoxin (ET) concentration in the blood serum of patients with AMI increasing from 1 to 14 day of the disease has been found. In women the concentration of ET was higher than in men. It allows to qualify the EA as a factor probably influencing the known difference in AMI tolerance in men and women. The source of ET were Bacteroides (most often--67.8% of patients), Klebsiella, Pseudomonas, Proteus, Escherichia coli. One or two bacteria more often took part in the development of EA. In 9.1% of patients the etiology of EA could not be verified, what indicates the presence of other sources of EA, not evaluated in this study. In 25% of patients with AMI serologic evidence of systemic candidiasis, caused by candida Albicans, has been found, what is able to enhance the biological effects of ET.
