• Patients with myocardial infarction exhibited a rise of serum aminopherase far above the levels found in normal subjects. The rise began after a lapse of 6 to 12 hours, reached its peak in 24 to 36 hours, and was followed by a decline, reaching normal levels by the fifth or sixth day. Patients with other forms of heart disease had normal values. Patients with liver disease had elevations of the serum aminopherase level, but the time relations differed.
