title: [Dynamics of changes in the levels of myoglobin and anti-myoglobin autoantibodies in the blood serum of patients with myocardial infarction].
abstract: The mean level of myoglobin and autoantibodies to myoglobin in the blood of healthy donors was 77.57 +/- 8.17 ng/ml and 18.01 +/- 1.85 micrograms/ml respectively. The level of myoglobin in the blood of patients with primary transmural myocardial infarction was rapidly increased, reaching its maximum in 9-12 h and returning to normal in 9 days. The mean level of autoantibodies was decreased in the first 66 h and got back to normal by the 6th day of disease. In primary large focal nontransmural myocardial infarction the concentration of myoglobin in the blood of patients was also increased, reaching its maximum in 3-9 h and returning to normal by the end of the 2nd day after onset of an angina attack. A decrease in the level of autoantibodies to myoglobin was observed up to the 18th day of disease. The peculiarity of repeated large focal nontransmural myocardial infarction was a two-peak curve of changes in a MG level with maximum levels in 9-12 and 21-24 h after onset of a pain attack. Final normalization of the level of myoglobin in the blood of patients of this group occurred in 69 h. The concentration of autoantibodies to myoglobin was more than once decreased up to the 6th day of disease. The results obtained showed that groups of examinees differed in the time course of changes in the level of myoglobin and autoantibodies to myoglobin. Such differences can be used for diagnostic purposes.
