title: Biological study of intravenous anisoylated plasminogen streptokinase activator complex in acute myocardial infarction.
abstract: An anisoylated plasminogen streptokinase activator complex (APSAC) has been administered as a bolus intravenous injection of 30U to 14 patients with acute myocardial infarction. Systemic effects on coagulation and fibrinolysis were studied. In 1 patient, the treatment produced no biological modification, which could be explained by an increased streptokinase resistance in this patient, apparent from the sample collected before treatment. In the other patients, as expected, fibrinogen, plasminogen, alpha 2-antiplasmin and factors V and VIIIc fell dramatically, while there was an increase in serum fibrinogen degradation product concentrations. In addition, plasma fibrin derivatives increased during APSAC therapy, both in patients who had occluded or patent coronary arteries. Discrepancies were found between methods used to measure fibrinogen: with the Ellis and Stransky method, concentrations were higher than with the Clauss method; and for plasminogen, automated methods using different analysers may give higher results in some patients.
