Изучение на разработанной нами модели синдрома «Праздничное сердце» у крыс особенностей микроциркуляции, функционального состояния и анатомии сердца.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Эксперименты проводили на белых беспородных крысах самцах. Синдром «Праздничное cердце» моделировали следующим образом: животные в течение первых 10 дней получали в качестве единственного источника жидкости 10 % водный раствор этанола, затем 10 дней — водопроводную воду и последующие 10 дней снова 10 % водный раствор этанола. Через сутки после окончания повторного приёма алкоголя животных брали в эксперимент. Контролем служили животные, получавшие свободный доступ к водопроводной воде. У части крыс опытной группы (n = 10) регистрировали эхокардиограмму до начала эксперимента и на 31-е сутки эксперимента, после чего у них методом лазерной допплеровской флоуметрии измеряли уровень микроциркуляции крови и лимфы в мозге и сердце. У оставшихся животных (n = 10) микроциркуляцию крови и лимфы в мозге и сердце оценивали на 3-и сутки алкогольной депривации.</p></sec><sec><title>Результаты</title><p>Результаты. Анализ полученных данных показал, что в условиях модели синдрома «Праздничное сердце» происходят существенные изменения в анатомии, функциональной активности и геометрии сердца: отмечается значимое истончение передней стенки левого желудочка сердца (ЛЖ), увеличение систолических и диастолических объёмов и размеров ЛЖ и существенное (р = 0,0018) снижение его инотропной функции. Эти изменения происходят на фоне значительного (р = 0,0081) снижения уровня микроциркуляции крови в миокарде, однако на 3-и сутки алкогольной депривации кровоток в микрососудах сердца статистически значимо (р = 0,0285) возрастает.</p></sec><sec><title>Заключение</title><p>Заключение. В модельных экспериментах, воспроизводящих синдром «Праздничное сердце», впервые показано, что этанол вызывает существенные изменения в микроциркуляции, анатомии, функциональной активности и геометрии ЛЖ сердца, что, по всей видимости, может играть одну из ключевых ролей в формировании патогномоничной для этого синдрома электрической нестабильности миокарда.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Studying the features of microcirculation, functional state and anatomy of the heart using the “Holiday Heart” syndrome model in rats we developed.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Experiments were carried out on white outbred male rats. The “Holiday Heart” syndrome was modeled as follows: animals received a 10 % aqueous ethanol solution as the only source of fluid for the first 10 days, then tap water for 10 days, and again a 10 % aqueous ethanol solution for the next 10 days. One day after the end of the repeated intake of alcohol, the animals were taken into the experiment. Animals that received free access to tap water served as control. Some rats in the experimental group (n = 10) had an echocardiogram recorded before the start of the experiment, and on the 31st day of the experiment, after which the level of microcirculation of blood and lymph in the brain and heart was measured using laser Doppler flowmetry. In the remaining animals (n = 10), microcirculation of blood and lymph in the brain and heart was assessed on the 3rd day of alcohol deprivation.</p></sec><sec><title>Results</title><p>Results. Analysis of the obtained data showed that in the conditions of the “Holiday Heart” syndrome model, significant changes occur in the anatomy, functional activity and geometry of the heart: there is a significant thinning of the anterior wall of the left ventricle heart (LV), an increase in systolic and diastolic volumes and sizes of the LV and a significant (p = 0.0018) decrease in its inotropic function. These changes occur against the background of a significant (p = 0.0081) decrease in the level of blood microcirculation in the myocardium, however, on the 3rd day of deprivation, blood flow in the microvessels of the heart increases statistically significantly (p = 0.0285).</p></sec><sec><title>Conclusion</title><p>Conclusion. In model experiments reproducing the “Holiday Heart” syndrome, it was shown for the first time that ethanol causes significant changes in the microcirculation, anatomy, functional activity and geometry of the left ventricle of the heart, which, apparently, can play a key role in the formation of myocardial electrical instability pathognomonic for this syndrome.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром «Праздничное сердце»</kwd><kwd>крысы</kwd><kwd>сердце</kwd><kwd>эхокардиография</kwd><kwd>микроциркуляция крови и лимфы</kwd><kwd>инотропная функция ЛЖ</kwd><kwd>ремоделирование ЛЖ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>“Holiday heart” syndrome</kwd><kwd>rats</kwd><kwd>heart</kwd><kwd>echocardiography</kwd><kwd>blood and lymph microcirculation</kwd><kwd>LV inotropic function</kwd><kwd>LV remodeling</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">Jain A., Yelamanchili V.S., Brown K.N., Goel A.
