In anesthetized open chest dogs, hydrocortisone (50 mg/kg body weight administered 30 minutes after occlusion and 25 mg/kg 12 hours later) substantially reduced the size of myocardial infarcts, as reflected by both myocardial creatine phosphokinase activity and histologic appearance 24 hours later. Similarly, hyaluronidase, which increases diffusion through the extracellular space and presumably facilitates delivery of substrate to ischemic cells, also reduced the extent of myocardial necrosis after coronary occlusion in the dog. In view of the salutary effects of hyaluronidase and the absence of serious side effects, this agent was administered clinically to two groups of patients, who were compared with two groups of untreated control subjects. Hyaluronidase (500 National Formulary units/kg X 8) was shown to result in a significantly more rapid reduction in the magnitude and the extent of precordial S-T segment elevations, and in patients treated within 4 hours a tendency to a lower incidence rate of Q waves and a smaller reduction of R waves.
