Serum Enzymes and Electrocardiograms after Coronary Arteriography

Abstract

CONFLICTING results regarding the effect of cardiac catheterization and angiocardiography on serum enzyme values have previously been reported.1 2 3 4 Although myocardial infarction is a complication of coronary arteriography,5 some patients may experience chest pain during coronary arteriography without development of criteria for acute infarction. It is essential to establish an early diagnosis of infarction, if it occurs, by changes in serum enzymes and electrocardiograms. Since other noncardiac factors, such as intramuscular injections,6 , 7 may contribute to changes in serum creatine phosphokinase values, their effects must also be recognized. Thus, when patients receive intramuscular premedication for angiographic procedures, it is necessary to know . . .
