[Esterase activity of neutrophils and monocytes in patients with stenocardia and myocardial infarction].

Neutrophils and monocytes of coronary patients and healthy subjects were investigated for activity of alpha-naphthylacetate esterase, naphthol--AS--D+chloroacetate esterase, alpha-naphthylbutyrate esterase. This activity varied from healthy to coronary subjects, among anginal and MI sufferers, etc. The fact made the authors to suggest comprehensive evaluation of monocyte and neutrophil esterase activity as a diagnostic and prognostic indicator.
