CPK Isoenzymes in Evaluation of Myocardial Ischemic Injury

Abstract
Enzymatic criteria for diagnosis of myocardial infarction have suffered from a lack of specificity, since enzyme elevations also occur in noncardiac disorders. The MB Coenzyme of creatine phosphokinase has provided a way out of this difficulty. Not only is specific to injured myocardium but a recently developed plasma assay makes possible both diagnosis and, in many cases, measurement of the extent of damage.
