Больные были распределены на две группы. В I группе (n = 55) периоперационно использовали инфузию левосимендана. Введение препарата (нагрузочная доза 12 мкг/кг/мин. в течение 10 мин.) начинали после вводной анестезии и продолжали инфузию на всех этапах операции и в ближайшем послеоперационном периоде. Общее время введения препарата составило 24 часа. Во II группе (n = 43) использовали стандартные препараты для коррекции системы кровообращения. Установлено, что включение левосимендана в комплексную программу кардиопротекции вызывало более быстрое восстановление гибернированного миокарда. Такое предположение основано на том, что у больных I группы использование левосимендана приводило к уменьшению объема гибернации после операции, в сравнении с дооперационным уровнем, на 42%. При этом, во II группе больных, оперированных без использования препарата, процент сокращения объема жизнеспособного миокарда составил 13%. Кроме того, обнаружена отчетливая зависимость состояния насосной функции сердца от гемодинамических влияний левосимендана. Так, у больных I группы выявлено увеличение сердечного индекса с 2,23±0,49 до 2,96±0,52 л./мин./м2 (p&lt;0,05), рост минутного объема крови с 4,51±0,99 до 6,04±1,1 л./мин. (p&lt;0,05), снижение давления заклинивания легочного клапана с 13,3±4,6 до 9,8±3,07 мм рт.ст. (p&lt;0,05). Кроме того, левосимендан оказывал отчетливый противоишемический эффект. Это нашло выражение в более низкой концентрации тропонина I у больных I группы, в сравнении с больными II гр., на этапе исследования после операции (I гр. – 2,78±2,31 нг./мл., II гр. – 3,45±4,9 нг./мл., p&lt;0,05). Следует отметить, что одновременно с уменьшением объема гибернированного миокарда, у больных I группы отмечено увеличение фракции выброса левого желудочка с 40% до 49% (p&lt;0,05). Приведенные данные свидетельствуют об улучшении функционального состояния миокарда на фоне профилактики ишемических и реперфузионных нарушений левосименданом. Было замечено, что дополнительное влияние на реализацию протекторных воздействий левосимендана могли оказывать дооперационный объем гибернированного миокарда и полноценность реперфузии. Таким образом, есть определенные основания считать, что кондиционирование миокарда левосименданом улучшало сократимость в зонах реперфузии гибернированного миокарда при операциях коронарного шунтирования у больных с ишемической дисфункцией левого желудочка</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study: to study the effect of perioperative use of levosimendan on the restoration of viable myocardium in patients with coronary artery disease with a significantly reduced left ventricular ejection fraction during myocardial revascularization. An open, prospective, randomized study was conducted, including 98 patients.The patients were divided into two groups. In group I (n = 55), levosimendan infusion was used perioperatively. Administration of the drug (loading dose of 12 mcg/kg/min for 10 minutes) began after induction of anesthesia and continued infusion at all stages of the operation and in the immediate postoperative period. The total time of drug administration was 24 hours. In group II (n = 43), standard drugs were used to correct the circulatory system. It was found that the inclusion of levosimendan in a comprehensive program of cardioprotection caused a more rapid recovery of hibernated myocardium. This assumption is based on the fact that in patients of group I, the use of levosimendan led to a decrease in the volume of hibernation after surgery, in comparison with the preoperative level, by 42%. At the same time, in group II of patients operated on without the use of the drug, the percentage reduction in the volume of viable myocardium was 13%. In addition, a clear dependence of the state of the pumping function of the heart on the hemodynamic effects of levosimendan was discovered. Thus, in patients of group I, an increase in cardiac index was detected from 2.23±0.49 to 2.96±0.52 l./min./m2 (p&lt;0.05), an increase in minute blood volume from 4.51± 0.99 to 6.04±1.1 l./min. (p&lt;0.05), decrease in pulmonary valve wedge pressure from 13.3±4.6 to 9.8±3.07 mmHg. (p&lt;0.05). In addition, levosimendan had a clear anti-ischemic effect. This was expressed in a lower concentration of troponin I in patients of group I, in comparison with patients of group II, at the stage of the study after surgery (I group – 2.78 ± 2.31 ng./ml., II group – 3.45 ±4.9 ng./ml., p&lt;0.05). It should be noted that, simultaneously with a decrease in the volume of hibernated myocardium, in patients of group I there was an increase in the ejection fraction of the left ventricle from 40% to 49% (p&lt;0.05). The data presented indicate an improvement in the functional state of the myocardium against the background of the prevention of ischemic and reperfusion disorders with levosimendan. It was noted that the preoperative volume of hibernated myocardium and the usefulness of reperfusion could have an additional influence on the implementation of the protective effects of levosimendan. Thus, there is some reason to believe that myocardial conditioning with levosimendan improved contractility in the reperfusion zones of hibernated myocardium during coronary artery bypass surgery in patients with ischemic left ventricular dysfunction</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ИБС</kwd><kwd>левосимендан</kwd><kwd>гибернированный миокард</kwd><kwd>реперфузия</kwd><kwd>кардиопротекция</kwd><kwd>реваскуляризация миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ischemic heart disease</kwd><kwd>levosimendan</kwd><kwd>hibernated myocardium</kwd><kwd>reperfusion</kwd><kwd>cardioprotection</kwd><kwd>myocardial revascularization</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">Kunst G, Klein AA.
