[Possibilities of early diagnosis of thromboembolic complications in myocardial infarct by means of biochemical methods].

A total of 41 patients with ischaemic heart disease and 30 normal donors were subjected to examinations of the biochemical indices of the blood coagulation system in its coagulation and anticoagulation links, as well as to tests reflecting the fibrinolytic and inhibitory activity of the urine. In the presence of thromboembolic complications in myocardial infarction patients a sharp elevation of "residual fibrinogen" and antiplasmins is noted along with a reduction of the urokinase activity of the urine.
