In patients with myocardial infarction, thrombolytic therapy induces a paradoxical activation of the hemostatic mechanism. In patients with unstable angina, the effect of thrombolysis on the coagulation cascade is unknown. We prospectively measured the plasma concentrations of prothrombin fragment 1 + 2 and fibrinopeptide A in consecutive patients with unstable angina randomized to receive plac...

The multicenter randomized study of the Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto Miocardico has provided the opportunity to analyze the impact of thrombolytic treatment on secondary ventricular fibrillation incidence in a large population of patients (11,712) with acute myocardial infarction. A reduction of about 20% in the frequency of secondary ventricular fibrillation ...

.. Several strains of beta-hemolytic Streptococci produce streptokinase enzyme that can bind and activate human plasminogen to plasmin. Streptokinase degrades the fibrin lump by its explicit lysine joining site and so it is applied as a remedy in thrombolytic therapy. The purpose of the study was to subject wild strain of Streptococcus equisimilis to strain development technique, using random m...

A computer model was developed to analyze the costs to Medicare and the potential procedure volume associated with alternative strategies for treatment of acute myocardial infarction. The expected cost per case to Medicare for initial hospitalization was approximately $7,200 for conventional treatment, $7,900 for treatment with intravenous streptokinase and $8,400 for treatment with recombinant...

Objective: The present study was undertaken to investigate the thrombolytic activity of Punica granatum fruit and peel extract. Methods: Phytoconstituents and free radical scavenging activity of P. granatum extract were performed. Ethanolic and aqueous extract of fruit and peel of the plant was used for in vitro clot lysis activity using streptokinase (SK) as standard. In a series of pre-weighe...

Thrombolytics recanalize thrombotic occlusion associated with STsegment elevation myocardial infarction (STEMI) and restoration of coronary flow reduces infarct size and improves myocardial function and survival over the short-term and long-term. Thrombolytic therapy for acute myocardial infarction (AMI) was incorporated into the armamentarium of clinicians over 2 decades ago, and has evolved f...

A data base of 1,511 patients admitted to a single Coronary Care Unit was analysed to examine the potential impact of thrombolytic therapy in elderly patients with myocardial infarction. Age was confirmed as a highly significant prognostic factor, and cost utility analysis showed that the cost of thrombolytic therapy with streptokinase in the elderly was lower per quality adjusted life year tha...
