Laboratory assessment of thrombolytic therapy in acute myocardial infarction.

Abstract

Hemostatic profiles and cardiac enzymes were studied in 55 acute myocardial infarct (AMI) patients to assess SK and rt-PA therapy. Hypofibrinogenemia occurred 85% in SK group and 55% in rt-PA group with high FDP and D-Dimer, indicating systemic fibrinogenolysis and local crosslinked fibrin clot lysis. The incidence of bleeding in SK and rt-PA groups combined with anticoagulants were the same but lower in rt-PA with antiplatelet. The mean FDP was significantly higher in the bleeding group (p < 0.01). Cardiac enzymes: CK, CK-MB peak values indicated reperfusion were 26.6%, 60% and 90% in conventional, SK and rt-PA therapy, respectively. Early and late occlusion did not occur either in SK or rt-PA followed by anticoagulants. Late occlusion was found in patients treated with rt-PA and antiplatelet. Mortality rate was 20% in conventional therapy.
