[Effect of infection foci and preexisting pathology on immunological shifts and the course of the disease in myocardial infarct patients].

The course of the disease and the dunamics of immunologic shifts were compared in 277 patients suffering from myocardial infarction, 87 of whom had foci of infection and chronic infectious-allergic diseases while 190 had no complications. In patients of the first group the disease was usually of a lingering character and anticardiac antibodies were found in circulation for lengthy periods of time. The incidence of chronic tonsillitis and odontogenous infectious foci was higher among patients with myocardial infarction complicated by the postinfarction syndrome than among those with a noncomplicated course of the disease (in 12 out of 20 and in 3 out of 20 patients, respectively).
