[Quantitative shifts in acid phosphatase isoenzymes in the blood in myocardial infarct].

The spectrum of acid phosphatase isoenzymes was studied by means of disk electrophoresis in polyacrylamide gel. Seven isofractions were detected of this enzyme in blood plasma. In patients with the acute stage of myocardial infarction the amount of isofraction 3 was increased, its electrophoretic mobility was 0.479 +/- 0.059. It is suggested to use the test for acid phosphatase fraction 3 in blood plasma as an auxiliary method in the diagnosis of pathological conditions of the myocardium.
