[Myocardial infarct repair in the light of clinico-biochemical and morphological studies]

To develop intravital criteria of the reperative processes following myocardial infarction, clinical, biochemical and morphological parallels were traced in 62 patients dying of myocardial infarction after different periods following the onset of the disease. It was demonstrated that a set of laboratory techniques (examinations of haptoglobin, chloridesoluble mucoprotein, of heterogeneity of mucoprotein, v2-macroglobulin) helps in the evaluation of the severity of the inflammatory and macrophagel reactions in the paranecrotic zone. A useful intravital sign of the formation of a postinfarction scar is provided by the examination of collagen metabolites--oxyproline bound with collagen-like plasma protein and free serum oxyproline and urine excretion of total oxyproline. The obtained data can be used for the development of a rehabilitation programme, differentiated therapy in various groups of patients.
