[Change in the index of neutrophil damage in infectious allergic myocarditis and its sequelae]

The reaction of damage to the blood neutrophils (the IND test) by a soluble cardiac antigen was studied in 10 healthy individuals, in 15 persons with infectious-allergic myocarditis and in 13 persons with myocarditic cardiosclerosis. Autoallergic shifts in relation to the cardiac antigen were revealed in half of the patients with infectious-allergic myocarditis and in one third of persons with myocarditic cardiosclerosis. The shifts were more marked in patients with infectious-allergic myocarditis.
