[Dynamics of 5'-nucleotidase activity in the blood plasma in experimental myocardial infarct]

The authors studied in the bloodflow the appearance of the damaged external cellular membranes of the heart during the development of experimental myocardial infarction. The appearance of the external cellular membranes was judged by the activity of their specific marked 51-nucleotidase. It was established that myocardial infarction leads to increased activity of 51-nucleotidase in the blood plasma, which is retained for about 1 month. The maximum of activity of 51-nucleotidase reflects the most intensive resorption of the damaged cardiac tissue, and is seen from 3 to 7 days after the accident. During these time limits thrombotic complications are especially dangerous.
