Эхокардиографию проводили на приборе Vevo 1100 с линейным датчиком 13–24 МГц. Инвазивное исследование сократительной функции сердца выполняли при помощи стандартного PV-катетера FTH-1912B-8018, усилителя ADV500, а также АЦП PowerLab 4 / 35 с программой LabChart 8.1. Крыс наркотизировали препаратом золетил 100 (5 мг/ кг). </p></sec><sec><title>Результаты</title><p>Результаты. При эхокардиографии у крыс через 8 нед от начала применения доксорубицина выявлена систолическая дисфункция со снижением фракции выброса левого желудочка (ЛЖ) на 32 %. В сердцах крыс, которым одновременно с доксорубицином вводили пластомитин (0,32 мг/ кг ежедневно), получено достоверное повышение фракции выброса и фракции укорочения по сравнению с таковыми в группе доксорубицина, и эти показатели были сопоставимы с контрольными. В опытах с одновременной регистрацией давления и объема ЛЖ было установлено, что сердца всех крыс, получавших доксорубицин, характеризовались снижением сократимости миокарда на 33 %, лежавшим в основе сниженной ударной работы на 40 %, при сохранении нормального минутного объема. Такая компенсация в опытах с изолированным введением доксорубицина достигалась посредством значительного снижения периферического сопротивления, замедления расслабления миокарда и увеличения периода наполнения ЛЖ при длительной диастолической паузе (частота сокращений была замедлена на 23 %). В опытах с одновременным применением доксорубицина и пластомитина компенсация осуществлялась при сохранении параметров сократимости и расслабимости миокарда, частоты сокращений и периферического сопротивления. Данный способ компенсации более выгоден для организма, поскольку при этом не нарушается снабжение органов и тканей кислородом, а при равной частоте сокращений группа пластомитина имела фракции укорочения и выброса, не отличавшиеся от контроля и значительно превосходившие соответствующие величины в группе изолированного введения доксорубицина. </p></sec><sec><title>Выводы</title><p>Выводы. Результаты позволяют прийти к заключению, что применение пластомитина в сочетании с доксорубицином предупреждает развитие систолической дисфункции, вызываемой доксорубицином.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to ascertain whether the use of plastomitin, the mitochondrial antioxidant, can affect the development of systolic dysfunction that occurs in rats after 4 weeks of doxorubicin treatment (2 mg/kg weekly). </p><sec><title>Materials and methods</title><p>Materials and methods. Male Wistar rats weighing 320–380 g were used in this work. Echocardiographic study was carried out using Vevo 1100 with linear probe 13–24 MHz frequency. </p></sec><sec><title>Results</title><p>Results. Echocardiographic study of rats through 8 weeks from the beginning of doxorubicin treatment showed the presence of systolic dysfunction with decrease of ejection fraction of the left ventricle (LV) by 32%. Hearts of rats, to which plastomitin (0.32 mg/kg daily) was administered simultaneously with doxorubicin, showed significantly increased ejection fraction and shortening fraction as compared with doxorubicin group, and these values were close to the control. In experiments with simultaneous registration of LV pressure and volume, it was found that the hearts of all rats treated with doxorubicin showed reduced contractility index and stroke work, while maintaining normal cardiac output. Such compensation in experiments with treatment with doxorubicin alone was achieved through significant reduction in the peripheral resistance, slowing of myocardial relaxation, and facilitation of LV diastolic filling during prolonged diastolic pause (the heart rate was slowed by 23%). In experiments with simultaneous application of doxorubicin and plastomitin, the compensation was achieved through preservation of myocardial contractility and relaxability, the heart rate and peripheral resistance. This method of compensation is more beneficial for the body, because it does not restrict the supply of organs and tissues with oxygen, and has significant advantage over doxorubicin group at equal heart rate. </p></sec><sec><title>Conclusion</title><p>Conclusion. The results allow to conclude that the use of plastomitin together with doxorubicin prevents the development of doxorubicin-induced systolic dysfunction.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>систолическая дисфункция</kwd><kwd>сократимость миокарда</kwd><kwd>диастолический объем</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта РФФИ № 18 015 00271.</funding-statement><funding-statement xml:lang="en">chronic heart failure; systolic dysfunction; myocardial contractility; diastolic volume</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">Mitry MA, Edwards JG.
