[Thyroid hormones, cholesterol, erythrocyte aggregation and fibrinogen degradation products in acute myocardial infarct].

One hundred and sixty-two patients with acute myocardial infarction, whose ages ranged from 36 to 65, were studied. The content of thyroid hormones was found to be reduced in the acute period of myocardial infarction. The triiodothyronine level was lower on the 2nd day of the disease, the thyroxine content decreased on the 10th day of the disease but became normal on the 20-25th day. An interrelation between the clinical course of the disease and the dynamics of changes in the cholesterol content, rate of erythrocyte aggregation, the content of fibrinogen degradation products, and the level of thyroid hormones was determined. Normalization of the values was determined. Normalization of the values studied occurred earlier in the group of patients with a more favourable course of the acute period of myocardial infarction than in those with severe myocardial infarction. The data obtained show a close interrelation between thyroid activity and values studied and the clinical course of the disease.
