Развитие сердечной недостаточности тесно связано с появлением жизнеугрожающих аритмий, которые нередко являются терминальным событием для данных пациентов. Анализ рандомизированных клинических исследований ингибиторов натрий-глюкозного котранспортера 2 типа свидетельствует о клинически значимом потенциале данных препаратов как средств с антиаритмическими свойствами. Однако полный механизм, за счет которого может реализоваться данный эффект, в настоящий момент все еще остается до конца не изученным.</p></sec><sec><title>Цель</title><p>Цель.

В эксперименте проводили выделение желудочковых кардиомиоцитов от 12 аутбредных мышей самцов. Были сформированы 2 группы: группа № 1 – контрольные желудочковые кардиомиоциты; группа № 2 – желудочковые кардиомиоциты после двух часовой инкубации с 5 µмоль/л раствором эмпаглифлозина. Выполнялись запись трансмембранных токов кальция и оценка внутриклеточных кальциевых переходных процессов.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Инкубация желудочковых кардиомиоцитов в присутствии эмпаглифлозина значительно увеличила плотность тока ICa и ускорила временную динамику Ca2+.

Результат эксперимента указывает на то, что эмпаглифлозин способен модулировать Са2+-зависимый механизм электромеханического сопряжения, усиливая и ускоряя выход Са2+ в цитоплазму и обратный его захват. Это предположительно оптимизирует, а именно сокращает время систолы и усиливает ее, что может являться одним из важных элементов проявления антиаритмических свойств эмпаглифлозина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The development of heart failure is closely associated with the appearance of life threatening arrhythmias, which are often a terminal event for these patients. An analysis of randomized clinical trials of inhibitors of sodium-glucose cotransporter type 2 indicates the clinically significant potential of these drugs as agents with antiarrhythmic properties. However, at the moment the full mechanism by which this effect can be realized is still not fully understood.</p></sec><sec><title>Aim</title><p>Aim. To evaluate the effect of empagliflozin on the transmembrane calcium currents and the intracellular calcium transients on isolated ventricular cardiomyocytes of mice under conditions of normoglycemia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. In the experiment, ventricular cardiomyocytes were isolated from 12 outbred male mice. 2 groups were formed: group № 1 – control ventricular cardiomyocytes; group № 2 – ventricular cardiomyocytes after two hours incubation with 5 µmol/L empagliflozin solution. Transmembrane calcium currents were recorded and intracellular calcium transients were assessed.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Incubation of ventricular cardiomyocytes with empagliflozin significantly increased ICa current density and accelerated Ca2+ temporal dynamics. The amplitude of the Ca2+ wave and the rate of rise and decay were increased and the duration of the Ca2+ wave was shortened.</p></sec><sec><title>Conclusion</title><p>Conclusion. The result of the experiment indicates that empagliflozin is able to modulate Ca2+-dependent mechanism of the excitation-contraction-coupling, enhancing and accelerating Ca2+ release into cytoplasm and reuptake. This presumably can optimize, namely reduce the time of systole and enhance it, which may be one of the important elements in the manifestation of empagliflozin antiarrhythmic properties.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ингибиторы натрий-глюкозного котранспортера 2 типа</kwd><kwd>изолированные желудочковые кардиомиоциты</kwd><kwd>трансмембранный ток кальция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sodium-glucose co-transporter 2 Inhibitors</kwd><kwd>isolated ventricular cardiomyocytes</kwd><kwd>transmembrane calcium currents</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Результаты работы получены при поддержке Российского фонда фундаментальных исследований (проект № 22-15-00186).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>This work was supported by the Russian Foundation for Basic Research (project no. 22-15-00186).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Santos-Gallego C.
