HYPERTROPHIC CARDIOMYOPATHY IN A PRESCHOOL CHILD. CLINICAL CASE
Hypertrophic cardiomyopathy is the most common form of cardiomyopathy in children. The disease is caused by mutations in the sarcomeric and non-sarcomeric complexes of the protein genes. It is the main cause of sudden cardiac death in young people. Hypertrophic cardiomyopathy can be associated with other diseases with many extracardiac symptoms, be the only manifestation of the disease, and also be asymptomatic for a long time. The basis of diagnosis is confirmation of an increase in the left ventricular myocardium by any imaging method, most often by echocardiography. Treatment of patients depends on the form of the disease, heart failure, cardiac arrhythmias and conduction disorders, angina, left ventricular outflow tract obstruction, etc. The prognosis and management tactics of the patient depend on risk factors for sudden cardiac death. The article presents a clinical case of hypertrophic cardiomyopathy in a child. A characteristic of the disease in a patient is the presence of risk factors for sudden cardiac death: debut of hypertrophic cardiomyopathy in preschool age, burdened family history, severe left ventricular hypertrophy, myocardial ischemia.
