В исследовании принял участие 31 пациент с ГКМП и обструкцией выходящего тракта ЛЖ, которым в дальнейшем была выполнена миосептэктомия по Морроу. С целью выявления нарушений ритма всем пациентам было выполнено суточное холтеровское мониторирование. Наличие и характер накопления контрастного вещества оценивали методом МРТ в раннюю и отсроченную фазы контрастирования.</p></sec><sec><title>Результаты</title><p>Результаты. Применение МРТ с контрастным усилением позволило выявить участки отсроченного контрастирования в гипертрофированных стенках ЛЖ – фиброзные изменения миокарда. Очаги фиброза были выявлены у 14 (45,2%) пациентов. У 5 (16,1%) больных при наличии изменений в миокарде нарушений сердечного ритма не выявлено. Мультивариантный регрессионный анализ факторов риска показал взаимосвязь между наличием очагов фиброза в миокарде ЛЖ и возникновением аритмии (р = 0,021). Наличие зон нарушения локальной сократимости (р = 0,327) и толщина гипертрофированной стенки (р = 0,146) значимого влияния на нарушение ритма сердечной деятельности не оказывают.</p></sec><sec><title>Выводы</title><p>Выводы. Наличие очагов отсроченного контрастирования (фиброза) в стенке ЛЖ, выявляемых методом МРТ, повышает шанс возникновения аритмии у больных с ГКМП в 12,9 раза. МРТ с контрастным усилением должна входить в алгоритм диагностики ГКМП, в том числе и для оценки наступивших структурных изменений миокарда.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim: to show the possibilities of the method of magnetic resonance imaging (MRI) in the detection and characterization of hypertrophic cardiomyopathy (HCM). Identify the relationship between the presence of foci of fibrosis in the myocardium of the left ventricle (LV) and the occurrence of arrhythmia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study involved 31 patients with HCM and obstruction of the LV outflow tract, who subsequently underwent Morrose's myoseptectomy. In order to detect abnormalities of rhythm, all patients underwent daily Holter monitoring. The presence and nature of the accumulation of contrast medium was assessed by the MRI method in the early and delayed phases of contrasting.</p></sec><sec><title>Results</title><p>Results. The use of MRI with contrast enhancement made it possible to identify areas of delayed contrast in the hypertrophied walls of the LV - fibrotic changes in the myocardium. The centers of fibrosis were revealed in 14 (45.2%) patients. In 5 patients (16.1%), there were no cardiac rhythm disturbances in the presence of changes in the myocardium. Multivariate regression analysis of risk factors showed the relationship between the presence of foci of fibrosis in the myocardium of the LV and the occurrence of arrhythmia (p = 0.021). The presence of violation zones of local contractility (p = 0.327) and the thickness of the hypertrophic wall (p = 0.146) have no significant effect on cardiac rhythm disturbance.</p></sec><sec><title>Conclusions</title><p>Conclusions. The presence of foci of delayed contrast (fibrosis) in the wall of the left ventricle, detected by MRI, increases the chance of arrhythmia in patients with HCM in 12.9 times. MRI with contrast enhancement should be included in the algorithm for diagnosis of HCM, including for evaluating the onset of structural changes in the myocardium.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гипертрофическая кардиомиопатия</kwd><kwd>фиброзные изменения миокарда</kwd><kwd>аритмия</kwd><kwd>магнитно -резонансная томография с контрастным усилением</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypertrophic cardiomyopathy</kwd><kwd>fibrotic changes in the myocardium</kwd><kwd>arrhythmia</kwd><kwd>magnetic resonance imaging with contrast enhancement</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">Maron B.J.
