Aspects of the Pediatric Non-Rheumatic Myocardial Disease Clinical and Functional Course

According to the World Health Organization, "myocarditis is an inflammatory disease of the myocardium, accompanied by dysfunction of the heart, and is diagnosed on the basis of established histological, immunological and immunohistochemical criteria." They can occur in children of all ages. Among children who died before the age of 10 months, they were found in 9% of cases. Clinically, non-rheumatic myocarditis in children is characterized by polymorphism, which can vary from asymptomatic forms to pronounced symptoms of severe refractory heart failure. All this indicates the relevance of studying this pathology in pediatric practice.
