Early diagnosis of myocardial infarction by arginase activity determination.
In blood serum of healthy persons the activity of arginase (EC 3.5.3.1) is very low, whereas in patients with myocardial infarction it increases within a few hours after the first attack of coronary pain, and returns to normal values after 3-5 days. No increase of arginase activity was observed in sera of patients with angina pectoris, coronary insufficiency or cardiac failure. Determination of arginase activity in blood serum may serve as a useful test in early differential diagnosis of myocardial infarction.
