Instrumental Methods of Diagnostics of Early Stages of Cardiomyopathies in Young People

Cardiomyopathies (CMP) are a heterogeneous group of myocardial diseases characterized by structural and functional changes in the heart muscle, often with a high risk of developing heart failure, arrhythmias and sudden cardiac death [1, 3, 4]. Due to the frequent subclinical course in the early stages, timely diagnosis of CMP remains one of the most important tasks of modern cardiology and laboratory medicine.
According to international and domestic epidemiological studies, the prevalence of CMP varies from 1:500 to 1:250 among the adult population, while a significant number of cases remain undiagnosed. Diagnostic errors at the preclinical stage lead to the loss of opportunities for timely prevention of disease progression [5]. Among young patients, cardiomyopathy is one of the leading causes of sudden cardiac death, especially in hypertrophic and arrhythmogenic forms.
