[Allergic pollen-induced myocarditis]. / Allergicheskii pyl'tsevoi miokardit.

The paper concerns two cases of allergic pollen myocarditis. The diagnosis was confirmed by an evident relationship of myocardial lesion to the period of pollen production by allergenic plants or parenteral injection of an allergen and with the respiratory manifestations of pollenosis. In addition to the clinical picture of myocarditis (heart pain, dyspnea, abnormal rhythm), there were also alterations in blood serum enzymes (AsG, ASL-O). Roentgenologically, there was an enlargement of the boundaries mainly on the part of the left ventricle. Flaccid pulsation, ECG abnormalities of the rhythm, conduction and repolarization common to myocarditis were established. Both patients received therapy in an allergen-free ward and completely recovered. It is believed that specific immunotherapy is contraindicated in such patients. The treatment should be carried out in an allergological or cardiological hospital and should consist in the exclusion of allergenic food, administration of glucocorticosteroids, antihistaminic drugs, cardiac glycosides and potassium drugs until full disappearance of the clinical manifestations, normalization of the ECG and laboratory characteristics.
