It is known that patients with NCLVM gradually develop contractile dysfunction, leading to chronic heart failure. Increased trabecularity is also noted in a number of other non-ischemic heart diseases, in particular, dilated cardiomyopathy (DCM), and sometimes differential diagnosis is a difficult task, especially in cases where the left ventricle ejection fraction (LVEF) is not reduced or reduced moderately, and LV dilation is insignificant. Recently, there has been evidence in the literature that myocardial strain, assessed using echocardiography and/or cardiac magnetic resonance imaging (CMR), can determine subclinical disorders of myocardial contractility and is more sensitive to functional changes than classical LVEF.</p> <p><bold><italic>AIM:</italic></bold><italic> </italic>To assess the myocardial strain parameters in patients with NCLVM and preserved LV EF compared with DCM and control group.</p> <p><bold><italic>METHODS:</italic></bold><italic> </italic>The study included patients with NCLVM with preserved LVEF, patients with DCM and patients without signs of cardiovascular disorders (control group). All patients underwent CMR with intravenous contrast administration.</p> <p><bold><italic>RESULTS:</italic></bold><italic> </italic>The study included 112 participants, including 16 patients with NCLVM with preserved LVEF, 51 patients from the control group without pathological changes in heart chambers according to CMR, and 45 patients with DCM. Mutations in the MYH7, MYBPC3, TTN and DES genes were previously detected in all patients with NCLVM with preserved LVEF. When studying the parameters of myocardial strain, a decrease in the parameters of global and segmental strain was revealed in patients with DCM, as well as a decrease in longitudinal and circumferential strain in patients with NCLVM compared with the normal group in the middle and apical segments, and radial strain in all segments.</p> <p><bold><italic>CONCLUSION:</italic></bold> Myocardial strain assessment can serve as a valuable diagnostic tool for detecting early contractility disorders in patients with NCLVM with preserved LVEF.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Некомпактный миокард левого желудочка (НКМЛЖ) представляет собой фенотипический вариант строения миокарда, при котором отмечается его повышенная трабекулярность с формированием двух отчетливых слоев: компактного и некомпактного. Известно, что у пациентов с НКМЛЖ может постепенно развиваться сократительная дисфункция миокарда, приводящая к сердечной недостаточности. Повышенная трабекулярность ЛЖ может встречаться как в норме, так и при ряде неишемических заболеваний сердца, в частности, при дилатационной кардиомиопатии (ДКМП). В некоторых случаях их дифференциальная диагностика представляет собой сложную задачу, особенно в случаях, когда фракция выброса (ФВ) не снижена или снижена умеренно, а дилатация ЛЖ незначительна. В последнее время в литературе появляются свидетельства того, что показатели деформации миокарда (синоним «myocardial strain»), оцененные с помощью эхокардиографии и/или магнитно-резонансной томографии (МРТ), могут выявлять ранние субклинические нарушения сократимости миокарда и могут быть более чувствительным показателем, чем ФВ ЛЖ.</p> <p><bold>Цель.</bold> Изучение показателей деформации у пациентов с НКМЛЖ с сохранной ФВ ЛЖ по сравнению пациентами с ДКМП и здоровыми лицами.</p> <p><bold>Методы</bold>. В исследование включались пациенты с НКМЛЖ с сохранной сократительной функцией ЛЖ, пациенты с ДКМП и пациенты из группы нормы. Всем пациентам выполнена МРТ сердца с внутривенным контрастированием.</p> <p><bold>Результаты</bold>. В исследование было включено 112 участников, из них 16 пациентов с НКМЛЖ с сохранной ФВ ЛЖ, 51 пациент из группы нормы без патологических изменений камер сердца по данным МРТ и 45 пациентов с ДКМП. У всех пациентов с НКМЛЖ и сохранной ФВ ЛЖ были ранее выявлены мутации в генах MYH7, MYBPC3, TTN и DES. При изучении параметров деформации миокарда было выявлено снижение параметров глобальной и сегментарной деформации у пациентов с ДКМП, а также снижение показателей продольной и циркулярной деформации у пациентов с НКМЛЖ по сравнению с нормой в средних и апикальных сегментах, а показателей радиальной деформации – во всех сегментах.</p> <p><bold>Выводы.</bold> Измерение показателей деформации миокарда может служить важным диагностическим инструментом выявления ранних нарушений сократимости у пациентов с НКМЛЖ и сохранной ФВ ЛЖ.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>myocardial strain</kwd><kwd>magnetic resonance imaging</kwd><kwd>left ventricle</kwd><kwd>non-compacted myocardium</kwd><kwd>dilated cardiomyopathy</kwd><kwd>ejection fraction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>деформация миокарда</kwd><kwd>магнитно-резонансная томография</kwd><kwd>левый желудочек</kwd><kwd>некомпактный миокард</kwd><kwd>дилатационная кардиомиопатия</kwd><kwd>фракция выброса</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Towbin JA, Lorts A, Jefferies JL.
