Abstract

Efficacy of streptokinase (SK) administered beyond the period of coronary occlusion with regard to ultimate infarct size and the extent of hemorrhagic infarction was assessed in primates. Eleven macaques underwent coronary occlusion for two hours and were then reperfused. Five of them were given a 2,000 U IV bolus of SK followed by a 10,000 U IV infusion over ninety minutes. The remaining 6 served as controls. Macaques were sacrificed seven days postocclusion. The left ventricle was sectioned parallel to the minor axis, and these were examined histologically for infarct size and hemorrhage. Multiplying the planimetric values by the thickness of the sections yielded the total volumes of left ventricle, infarction, and hemorrhage. The mean percentage of left ventricle involved in infarction in the treated group was not significantly different from the controls (14.06 +/- 6.35 versus 16.50 +/- 4.67, P > 0.10). SK-treated animals had a significantly greater volume of infarct involved with hemorrhage as compared with controls (27.1 +/- 10.8 versus 4.0 +/- 1.4, P < 0.05). SK infusions done concurrently with reperfusion following a two-hour occlusion did not result in a significant reduction or increase in the size of infarct. However...Continue Reading
