Serum Iron, Glutamic Oxalacetic Transaminase and Creatine Phosphokinase in Acute Myocardial Infarction

The serum iron was subnormal on the first three days, following acute myocardial infarction in thirty patients. This is significantly less than the incidence of abnormalities demonstrated by assays of creatine phosphokinase (CPK) and glutamic oxalacetic transaminase (SGOT) in serum. Occasional patients had abnormal serum iron concentrations in association with normal CPK activities. For this reason serum iron determination may usefully supplement CPK activity measurements and possibly those of SGOT activity as an aid to the detection of acute myocardial infarction.
