[Hydroxyproline in blood and urine in myocardial infarct]

The study of the dynamics of proteinbound blood plasma oxyproline concentration and oxyproline excretion with the urine in patients with myocardial infarction is reported. During the subacute period beginning from the 3rd to the 5th week of the disease an increase in the content of these metabolites in the blood and urine is observed. The time of the beginning and the end of this period depends on a number of factors: the depth and spread of necrosis focus, the presence of certain accompanying diseases and complications, peculiarities of the clinical course of the disease. The dynamics of the concentration of proteinbound blood oxyproline and oxyproline excretion with urine in myocardial infarction is regarded as a test that gives information about the rate and intensity of scar formation in myocardial infarction.
