title: Enzyme changes after coronary angiography.
abstract: The enzymatic response to contrast media after coronary angiography was observed in 24 patients. The enzymes studied were glutamic oxaloacetic transaminase (SGOT), glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), gamma-glutamyl transferase (gamma-GT), creatine phosphokinase (CPK), and the myocardial-specific isoenzyme of CPK (CK-MB). Angiography produced no significant elevations in SGOT, SGPT, alpha-HBDH, LDH, or CK-MB activities; gamma-GT increased up to the twelfth hour. High levels of CPK and CK-MB observed in one patient were found to be products of a thymus carcinoma. In vitro examinations also showed that concentrations of contrast media used in coronary angiography do not inhibit gamma-GT, LDH, and CPK activities.
