Нами показано, что концентрация свободно-циркулирующеймтДНК крови через 24 часа после наложения лигатуры проявила тенденцию к снижению, а через 48 и 72 часа увеличилась и достигла значений, близких к контролю. Полученные данные определяют необходимость дальнейших исследований динамики данного показателя на более отдаленных сроках моделирования ишемии миокарда, что будет способствовать объективной оценке его значения для диагностики и прогнозирования острых повреждений миокарда.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the present study is to analyze the dynamics of free circulating mtDNA level in blood after occlusion of the upper one-third left descending branch of the coronary artery. We showed that the concentration of free circulating mtDNA of blood tends to decrease 24 hours after ligation; it increased and reached values close to control samples 48 and 72 hours after ligation. These data define the need in further investigation of the dynamics of this parameter during later periods of myocardial infarction modeling that will contribute to objective evaluation of its significance for acute myocardial damage diagnostics and prognosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>перевязка левой коронарной артерии</kwd><kwd>ишемия миокарда</kwd><kwd>уровень мтДНК</kwd><kwd>биомаркеры цитолиза кардиомиоцитов</kwd><kwd>ПЦР в реальном времени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>occlusion of the left coronary artery</kwd><kwd>myocardial ischemia</kwd><kwd>mtDNA level</kwd><kwd>biomarkers of cardiomyocite cytolysis</kwd><kwd>real time PCR</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">Судаков Н.П., Никифоров С.Б., Константинов Ю.М. и др.
