;Aspartate Aminotransferase (AST) 60 IU/L.
:AST is a NON-SPECIFIC marker of myocardial infarction (i.e., it is also elevated in other conditions, such as liver disease and skeletal muscle injury). AST levels peak at 48--72 hours following the infarction. A normal AST level would be less than 37 IU/L.
 
;Total Creatine Phosphokinase (CPK) 165 IU/L.
:An elevated total CPK (a collective measure of all CPK isoenzymes) is a NONSPECIFIC marker for myocardial infarction. However, an elevation in the level of CPK-MB isoenzyme is a more specific marker for myocardial infarction. CPK levels begin to rise 4-8 hours following an infarction, usually peak within the first 24-48 hours, and then return to baseline within 3-4 days. A normal CPK level is 35 to 250 IU/L.
