Abstract

A series of 16 consecutive patients with acute myocardial infarction was investigated with respect to changes in coagulatory parameters after intravenous short-term treatment with 1,500 000 IU streptokinase (SK) over a period of 90 minutes. Samples for coagulation assays (fibrinogen, thrombin, time activated partial thromboplastin time (aPTT), normotest, thrombin-coagulase time, platelets, antithrombin III, plasminogen and antiplasmin activity, alpha 2-macroglobulin, alpha 1-antitrypsin, factor X a were collected before and immediately after iv SK, and after 4, 8, 12, 24, 36, 48 and 72 hours. Platelets, antithrombin III, factor X a, alpha 1-antitrypsin and alpha 2-macroglobulin showed no changes over the observed period. The concentrations of fibrinogen and the activities of plasminogen and antiplasmin decreased clearly during the first 24 hours, reaching a minimum immediately after SK administration. Thrombin time and aPTT were prolonged for 36 hours, with a maximum in the first hours after lysis. Invasive diagnostic and/or therapeutic procedures during the first 24 hours after SK lysis should be carried out only for a definite, strict indication and under repeated control of the coagulatory status. After 24-36 hours there is ...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
