we studied the possibility of enzymatic estimation of myocardial infarct size in patients late ( between days 2 and 6 ) after the onset of acute myocardial infarction ( ami ) , in whom estimation of infarct size was difficult by analysis of time-activity curves of serum creatine kinase ( ck ) because of the lack of the enzymatic information during the initial 48 hours .
