Анализ включал мониторинг состояния здоровья исследуемой группы детей по данным медицинской информационной системы Damumed. Выявленные изменения были разделены на периоды: возникшие в первые 6 месяцев, в течение года, 2 лет и более 2 лет после заболевания.</p></sec><sec><title>Результаты</title><p>Результаты: Заболевания, возникшие в катамнезе при амбулаторном мониторинге, включали пневмонию (9,6 %), нарушения вегетативной регуляции (11,8 %), офтальмологическую патологию (7,5 %), поражение суставов (6,6 %), метаболические нарушения (2,2 %), рецидив мультисистемного воспалительного синдрома (2,2 %). Исследование сердечно-сосудистой системы выявило отличающиеся от острого периода мультисистемного воспалительного синдрома изменения, свидетельствующие о регрессии симптомов воспалительного процесса в сердце (кардиомегалии, дисфункции левого желудочка, перикардита, легочной артериальной гипертензии, коронаритов, митральной регургитации), увеличение (64,1 %) клапанного поражения правых отделов сердца (регургитаций легочного и трикуспидального клапанов), аритмий по сравнению с острым периодом (p&lt;0,005). Все эти изменения в большинстве случаев отмечались в 1-й год наблюдения.</p></sec><sec><title>Выводы</title><p>Выводы: В отдаленном периоде после перенесенного мультисистемного воспалительного синдрома, ассоциированного с SARS-CoV-2, дети имели различные соматические расстройства. У большинства пациентов (64,1 %) в 1-й год наблюдения сохранялись субклинические признаки поражения миокарда.</p></sec></abstract><trans-abstract xml:lang="en"><p>Existing data on the follow-up of children with SARS-CoV-2-associated Multisystem Inflammatory Syndrome are limited.</p><p>The purpose of this study.

A retrospective study was conducted that included 93 children with a history of SARS-CoV-2-associated Multisystem Inflammatory Syndrome. The analysis included monitoring the health status of the study group of children using data from the Damumed medical information system. Identified changes were categorized into the following periods: occurring within the first 6 months, 1 year, 2 years, and more than 2 years post-illness.</p></sec><sec><title>Results</title><p>Results: Diseases identified during outpatient monitoring in the follow-up included pneumonia (9.6 %), vegetative-vascular dystonia (11.8 %), vision deterioration (7.5 %), joint damage (6.6 %), metabolic disorders (2.2 %), and recurrence of Multisystem Inflammatory Syndrome (2.2 %). Cardiovascular system assessment revealed changes unusual for the acute period of MIS: regression of symptoms of the inflammatory process of the heart in the form of cardiomegaly, left ventricular dysfunction, pericarditis, pulmonary arterial hypertension, coronary artery disease, mitral regurgitation, and an increase in valvular disease of the right heart chambers (regurgitation of the pulmonary and tricuspid valves), arrhythmias compared to the acute period (p&lt;0.005). These changes were predominantly observed during the first year of follow-up.</p></sec><sec><title>Conclusions</title><p>Conclusions: Children who had Multisystem Inflammatory Syndrome associated with SARSCoV-2 exhibited various somatic disorders during long-term monitoring. The majority of patients (64.1 %) continued to have subclinical signs of myocardial damage within the first year of observation.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мультисистемный воспалительный синдром</kwd><kwd>ассоциированный с SARSCoV-2</kwd><kwd>катамнестическое наблюдение</kwd><kwd>эхокардиография</kwd><kwd>электрокардиография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Multisystem Inflammatory Syndrome</kwd><kwd>SARS-CoV-2 associated</kwd><kwd>catamnestic observation</kwd><kwd>echocardiography</kwd><kwd>electrocardiography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Noval Rivas M., Porritt R.
