Macro-lactate dehydrogenase in serum after acute myocardial infarction.

17 ± 2.7 1.9 ± 0.4 5.9 ± 0.7 89 ± 28 Van Acker et al. (1) reported the presence of macro-LDH in serum 10 days after administration of streptokinase in the very acute phase of an acute myocardial infarction (AM!). They claimed a causal relationship between the finding of macro-LDH and administered streptokinase. However, a relationship with AM! itself, or its underlying cause, is not to be excluded. 14 ± 3.9 1.7 ± 0.5 4.9 ± 1.0 100 ± 24 Surveying our own series, we found
