Цель обзора: всесторонне представить особенности клинической диагностики миокардитов у детей.</p><p>Наличие миокардита следует предполагать в ситуациях, когда у детей, независимо от возраста, впервые появились симптомы сердечной недостаточности, а также при наличии клиники вирусных инфекций, сопровождающейся респираторными или абдоминальными симптомами, в совокупности с развитием тахикардии, гипотонии или нарушений сердечного ритма, даже при отсутствии кардиомегалии. Следует клинически заподозрить миокардит на этапе, когда должны быть приняты необходимые решения о маршрутизации больного, формировании комплекса диагностических обследований и старте терапии. Магнитно-резонансная томография сердца является сегодня неинвазивным золотым стандартом диагностики миокардита и позволяет выявить миокардит в течение 2–3 нед после появления первых симптомов. Для точной морфологической диагностики миокардита у детей может быть использована эндомиокардиальная биопсия. Значимыми для диагностики миокардитов у детей являются молекулярно-биологические и генетические исследования, определяющие тяжесть течения и исход заболевания.</p><sec><title>Заключение</title><p>Заключение.

A review of the current literature on the features of the diagnosis of myocarditis in children is presented. Myocarditis is an acute or chronic inflammatory myocardial disease characterized by a variety of clinical manifestations, nonspecific symptoms and physical data. With insufficient number of informative diagnostic tests, there is a challenge for practitioners at all stages of medical care. Aim of the review is to comprehensively present the features of the clinical diagnosis of myocarditis in children. The presence of myocarditis should be assumed in situations where children, regardless of the age, first developed symptoms of heart failure (HF), as well as in the presence of a clinic of viral infections accompanied by respiratory or abdominal symptoms, combined with the development of tachycardia, hypotension or cardiac arrhythmias, even in the absence of cardiomegaly. Myocarditis should be clinically suspected at the stage when the necessary decisions should be made about the patient’s routing, the formation of a complex of diagnostic examinations and the start of therapy. Magnetic resonance imaging (MRI) of the heart is today the non-invasive gold standard for the diagnosis of myocarditis that allows detecting myocarditis within 2–3 weeks after the first symptoms appear. Endomyocardial biopsy can be used for accurate morphological diagnosis of myocarditis in children. Molecular biological and genetic studies that determine the severity and outcome of the disease are important for the diagnosis of myocarditis in children.</p></sec><sec><title>Conclusion</title><p>Conclusion. Based on the literature data and own experience in diagnosing myocarditis, the authors have developed an original diagnostic algorithm to make the right medical decision in case of suspected acute myocarditis in children.</p></sec><sec><title>Contribution</title><p>Contribution: Vasichkina E.S. — concept and design of the study; Vasichkina E.S., Balykova L.A., Basargina E.N., Bregel L.V., Degtyareva E.A., Kovalev I.A., Kotlukova N.P., Leontyeva I.V., Yakovleva L.V., Groznova O.S. — collection and processing of material; Vasichkina E.S., Kovalev I.A., Kotlukova N.P., Leontyeva I.V. — writing the text; Balykova L.A., Basargina E.N., Bregel L.V., Degtyareva E.A., Yakovleva L.V., Groznova O.S. — editing the text.
