G. A1 van der Laarse, Arnoud A1 van der Wall, Ernst E. YR 1990 UL http://www.ccjm.org/content/57/6/547.abstract AB Determination of infarction size is essential to evaluate interventions designed to salvage myocardium. Properly executed enzyme methods probably have the highest accuracy but can only be used in the early stage of infarction. Measurement of slowly catabolized enzymes such as LDH, LDH-1, and alpha-HBDH is recommended for routine purposes.
