Кардиомиопатия (КМП) является ведущей причиной смертности при дистрофинопатиях. Стандартные методы скрининга часто не выявляют ранние доклинические изменения. Целью исследования была сравнительная оценка диагностической ценности современных методов (глобальный продольный стрейн — GLS, суточное мониторирование ЭКГ — ХМ-ЭКГ, биомаркёры повреждения миокарда) в выявлении ранней кардиальной дисфункции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В проспективное кросс-секционное исследование был включён 31 пациент с мышечной дистрофией Дюшенна/Беккера (МДД/МДБ). Всем пациентам выполнена комплексная оценка: эхокардиография (ЭхоКГ) с анализом GLS, ХМ-ЭКГ, определение уровней предсердного натрийуретического пептида (NT-proBNP) и тропонина I.</p></sec><sec><title>Результаты</title><p>Результаты. Снижение фракции выброса левого желудочка (ФВ ЛЖ) &lt; 50% выявлено у 5 (16,1%) пациентов. При сохранной ФВ ЛЖ у 68,8% пациентов отмечалось субклиническое снижение GLS. ХМ-ЭКГ статистически значимо чаще выявляла тахикардию, чем разовая ЭКГ (p &lt; 0,050), а также сочетание тахикардии со сниженной вариабельностью ритма и высокой желудочковой эктопической активностью.Уровень NT-proBNP был достоверно выше в группе с ФВ ЛЖ &lt; 50% (279,8 [73,28; 844,8] против 60,83 [34,24; 104,5] пг/мл; p = 0,020).</p></sec><sec><title>Заключение</title><p>Заключение. Методы speckle-tracking ЭхоКГ и ХМ-ЭКГ обладают существенно более высокой чувствительностью в выявлении доклинической КМП при МДД/МДБ по сравнению со стандартным скринингом. Их комбинированное применение с определением NT-proBNP и тропонина I позволяет стратифицировать риск и обосновать раннее начало кардиопротективной терапии.</p></sec><sec><title>Вклад авторов</title><p>Вклад авторов:Попович С.Г. — концепция и дизайн статьи, написание текста, редактирование;Каверина В.Г. — написание текста;Сдвигова Н.А. — написание, редактирование текста;Сильнова И.В. — написание, редактирование текста;Увакина Е.В. — написание, редактирование текста;Басаргина Е.Н. — концепция и дизайн статьи, написание текста, редактирование;Кузенкова Л.М. — концепция и дизайн статьи, написание текста, редактирование.Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Финансирование</title><p>Финансирование.

Cardiomyopathy is the leading cause of mortality in dystrophinopathies. Standard screening methods often fail to detect early preclinical changes. The aim of the study was a comparative assessment of the diagnostic value of modern methods (global longitudinal strain — GLS, 24-hour ECG monitoring — Holter monitoring, myocardial damage biomarkers) in detecting early cardiac dysfunction.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A prospective cross-sectional study included thirty one patient with Duchenne/Becker muscular dystrophy (DMD/BMD). All patients underwent comprehensive assessment including echocardiography with GLS analysis, 24-hour Holter monitoring, determination of NT-proBNP and troponin I levels.</p></sec><sec><title>Results</title><p>Results. Reduced left ventricular ejection fraction (LVEF &lt; 50%) was detected in 5 patients (16.1%). In patients with preserved LVEF, subclinical reduction in GLS was noted in 68.8%. Holter monitoring detected tachycardia significantly more often than a single ECG recording (p &lt; 0.050), as well as a combination of tachycardia with reduced heart rate variability and high ventricular ectopic activity. The NT-proBNP level was significantly higher in the group with LVEF &lt; 50% (279.8 [73.28; 844.8] vs. 60.83 [34.24; 104.5] pg/mL, p = 0.020).</p></sec><sec><title>Conclusion</title><p>Conclusion. Speckle-tracking echocardiography and 24-hour Holter monitoring have significantly higher sensitivity in detecting preclinical cardiomyopathy in DMD/BMD compared to standard screening. Their combined use with the determination of NT-proBNP and troponin I allows the risk stratificating and justifying early initiation of cardioprotective therapy.</p></sec><sec><title>Contributions</title><p>Contributions:Kaverina V.G. — writing the text;Sdvigova N.A. — writing, editing the text;Silnova I.V. — writing, editing the text;Popovich S.G. — writing, editing the text;Uvakina E.V. — writing, editing the text;Basargina E.N. — conception and design of the article, writing the text, editing;Kuzenkova L.M. — conception and design of the article, writing the text, editing.All co-authors are responsible for the integrity of all parts of the manuscript and approval of its final version.</p></sec><sec><title>Funding</title><p>Funding.
