RESUMO
Efficiency and safety of an accelerated regimen of streptokinase (1.5 M.U. over 20 min., 109 patients) has been compared with the standard regimen (1.5 M.U. over 60 min, 119 patients) in 218 patients admitted within the first 6 hours after the onset of the symptoms of acute myocardial infarction. Using the noninvasive criteria we found a coronary reperfusion rate of 77.04% in patients belonging to the accelerated regimen group and this value was significantly higher than the one of 57.14% registered in the standard group. No major hemorrhagic events were registered in both groups. Although the hypotension appeared to be more frequent in patients in whom the accelerated regimen was used, however this side effect proved to be transient and well controlled using the rapid infusion of natrium chloride solution. In conclusion, the accelerated regimen of streptokinase is safe and followed by a higher rate of coronary reperfusion as compared to the standard one.
