Пандемия COVID-19 выявила необходимость разработки надежных диагностических критериев для оценки состояния миокарда у лиц, перенесших инфекцию и вакцинацию. Отсутствие стандартизированных референсных значений параметров магнитно-резонансной томографии (МРТ) сердца для молодой популяции ограничивает возможности точной интерпретации выявляемых изменений.</p></sec><sec><title>Цель</title><p>Цель: установить референсные значения морфофункциональных параметров миокарда методом мультипараметрической МРТ у молодых лиц, перенесших COVID-19 в легкой форме и / или вакцинированных против SARS-CoV-2.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В одномоментное поперечное исследование включены 28 добровольцев в возрасте 18–29 лет без сердечно-сосудистой патологии. Всем участникам выполнена мультипараметрическая МРТ сердца на томографе 1,5 Тл с последующей количественной оценкой морфофункциональных параметров и показателей деформации миокарда с помощью программного обеспечения Medis 3.0.18.10. Предварительно проведена оценка согласованности врачебных измерений с использованием коэффициента вариации и коэффициента внутриклассовой корреляции (ICC).</p></sec><sec><title>Результаты</title><p>Результаты. Наибольшая согласованность врачебных измерений характерна для глобальной продольной деформации (GLS) (ICC = 0,91) и конечно-диастолического объема (КДО) (ICC = 0,89), тогда как глобальная радиальная деформация (GRS) демонстрирует наибольшую вариабельность врачебных оценок (ICC = 0,72). При оценке фракции выброса (ФВ) левого желудочка (ЛЖ) выявлен наименьший коэффициент вариации (8,9%), что подтверждает его надежность как основного функционального параметра работы ЛЖ. Референсные значения показателей функции сердца приведены с интервалом 2,5–97,5 перцентили.</p></sec><sec><title>Заключение</title><p>Заключение. Согласованность оценки функциональных параметров экспертами с разным опытом работы создает основу для стандартизированного подхода к интерпретации данных МРТ сердца у молодых пациентов. Полученные референсные значения показателей функции сердца могут служить ориентиром при выявлении отклонений, ассоциированных с воспалительными изменениями в сердце не только в результате перенесенного COVID-19 и вакцинации, но и других этиологических факторов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The COVID-19 pandemic has revealed the need for reliable diagnostic criteria to assess myocardial status in individuals who have recovered from the infection or undergone vaccination. The lack of standardized reference values for cardiac magnetic resonance imaging (MRI) parameters in the young population limits the accurate interpretation of detected changes.</p></sec><sec><title>Aim</title><p>Aim: To establish reference values for myocardial morpho-functional parameters using multiparametric cardiac magnetic resonance imaging (MRI) in young individuals who have had COVID-19 and/or were vaccinated against SARS-CoV-2.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. A single-center cross-sectional study included 28 volunteers (18-29 years old) without cardiac pathology. All participants underwent multiparametric cardiac MRI on a 1.5 T scanner, followed by quantitative assessment of morpho-functional parameters and myocardial deformation indices using Medis Suite software version 3.0.18.10. Preliminary, the assessment of interobserver agreement using variation coefficient and intraclass correlation coefficient (ICC) were carried out.</p></sec><sec><title>Results</title><p>Results. The highest agreement was observed for global longitudinal strain (ICC = 0.91) and end-diastolic volume (ICC = 0.89), while global radial strain demonstrated the greatest variability (ICC = 0.72). Ejection fraction showed the lowest coefficient of variation (8.9%), confirming its reliability as a primary functional parameter. Reference values for cardiac MRI parameters were established for the young population with percentile interval.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained assessment of methodological consistency provides a basis for a standardized approach to interpreting cardiac MRI data in young patients. The developed set of reference values can serve as a benchmark for identifying deviations associated with inflammatory changes, not only resulting from past COVID-19 and vaccination, but other etiological factors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>магнитно-резонансная томография сердца</kwd><kwd>референсные значения</kwd><kwd>COVID-19</kwd><kwd>вакцинация</kwd><kwd>деформация миокарда</kwd><kwd>согласованность измерений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac MRI</kwd><kwd>reference values</kwd><kwd>COVID-19</kwd><kwd>vaccination</kwd><kwd>myocardial deformation</kwd><kwd>measurement agreement</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено без финансовой поддержки грантов, общественных, некоммерческих, коммерческих организаций и структур.
