Changes in left ventricular function after intracoronary streptokinase infusion in clinically evolving myocardial infarction

Abstract Left ventricular (LV) contrast cineventriculograms were obtained in 174 patients with evolving acute myocardial infarction (AMI) treated by intracoronary streptokinase (SK) infusion. Ejection fraction (EF) increased slightly, from 52% ± 13% before admission SK intervention to 58% ± 13% immediately after early recanalization of the completely obstructed coronary vessel ( p p p p p
