To evaluate the dynamics of the parameters of autonomic balance and electrical instability of the myocardium depending on the effectiveness of the restoration of coronary blood flow in pharmacoinvasive revascularization in patients with acute ST segment elevation myocardial infarction.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 91 patients who underwent effective thrombolytic therapy (TLT) according to the ECG criteria, followed by (3-24 hour later) coronary angiography with percutaneous coronary intervention (PCI). Before and after PCI the telemetric ECG recording was conducted. The dynamics of the temporal and spectral characteristics of heart rate variability (HRV), presence of ventricular late potentials (VLP) and abnormal heart rate turbulence (HRT) were evaluated.</p></sec><sec><title>Results</title><p>Results. The episodes of ST-segment re-elevation by1 mm or more, lasting at least 1 min, and the dynamics of some HRV indices indicated the development of rethrombosis after TLT. The increase in the mean square deviation of normal intervals to 82.5 (64.5; 94) ms, the average value of the standard deviations of normal intervals calculated over 5-minute intervals throughout the entire recording to 37.5 (31.5; 47.5) ms, the total power of the spectrum and the power of high frequency waves, as well as the decrease in the power of ultra-low frequency waves were found after PCI in the group with a rethrombosis of the infarct-related coronary artery. The analysis of VLP in this group showed an increase in duration of the filtered QRS complex after TLT (to 128.7±34.5 ms), and the root mean square value of the last 40 ms of the QRS complex after PCI (to 49±50.3 μV).</p><p>Pathological deviations of the HRT parameters (especially the onset of turbulence) independently on the absolute values were registered more often in patients with rethrombosis, and abnormal values of both HRT parameters were found only in patients with episodes of unstable coronary blood flow.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results are the indirect evidences of disruption of autonomic regulation of cardiac activity and increased arrhythmic readiness of myocardium in developing rethrombosis of coronary artery. The pronounced reperfusion injury of the myocardium evidently plays an important role in this process and is associated with embolization of the vessels of the microcirculatory bed, release of free radicals and alteration of cardiomyocytes, especially due to prolonged ischemia.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить динамику показателей вегетативного баланса и электрической нестабильности миокарда в зависимости от эффективности восстановления коронарного кровотока при фармакоинвазивной реваскуляризации у больных острым инфарктом миокарда с подъемом сегмента ST.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование включен 91 пациент, которым проведена эффективная по ЭКГ-критериям тромболитическая терапия (ТЛТ), через 3-24 ч после которой выполнена коронароангиография с чрескожным коронарным вмешательством (ЧКВ). До и после ЧКВ проводили телеметрическую регистрацию ЭКГ. Оценивали динамику временных и спектральных характеристик вариабельности сердечного ритма, наличие поздних потенциалов желудочков и патологической турбулентности сердечного ритма.</p></sec><sec><title>Результаты</title><p>Результаты. На развивающийся после ТЛТ ретромбоз указывали эпизоды реэлевации сегмента ST на1 мм и более, продолжительностью не менее 1 мин, и динамика ряда показателей вариабельности сердечного ритма. После ЧКВ в группе с ретромбозом инфаркт-связанной коронарной артерии возросли среднее квадратичное отклонение нормальных интервалов до 82,5 (64,5; 94) мс, среднее значение стандартных отклонений нормальных интервалов, вычисленных по 5-минутным промежуткам в течение всей записи, до 37,5 (31,5; 47,5) мс, общая мощность спектра и мощность волн высокой частоты, а также снизилась мощность волн ультранизкой частоты. При анализе поздних потенциалов желудочков установлено, что в этой группе увеличивалась продолжительность фильтрованного комплекса QRS после ТЛТ (до 128,7±34,5 мс) и среднеквадратичное значение последних 40 мс комплекса QRS после ЧКВ (до 49±50,3 мкВ).</p><p>Патологические отклонения показателей турбулентности сердечного ритма, особенно начала турбулентности, независимо от абсолютных значений чаще встречались у пациентов группы с ретромбозом, а аномальные значения обоих показателей турбулентности сердечного ритма отмечались только у больных с эпизодами нестабильности коронарного кровотока.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты косвенно свидетельствуют о срыве вегетативной регуляции сердечной деятельности и повышении аритмической готовности миокарда при развивающемся ретромбозе коронарной артерии. Немаловажную роль в этом процессе, очевидно, играет выраженное реперфузионное повреждение миокарда, которое связано с эмболизацией сосудов микроциркуляторного русла, высвобождением свободных радикалов и альтерацией кардиомиоцитов, особенно вследствие пролонгированной ишемии.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>острый инфаркт миокарда с подъемом сегмента ST</kwd><kwd>тромболитическая терапия</kwd><kwd>чрескожное коронарное вмешательство</kwd><kwd>ретромбоз</kwd><kwd>вариабельность сердечного ритма</kwd><kwd>турбулентность сердечного ритма</kwd><kwd>поздние потенциалы желудочков</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ST segment elevation myocardial infarction</kwd><kwd>thrombolytic therapy</kwd><kwd>percutaneous coronary intervention</kwd><kwd>rethrombosis</kwd><kwd>heart rate variability</kwd><kwd>heart rate turbulence</kwd><kwd>ventricular late potentials.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Министерство образования и науки Российской Федерации (задание № 18.1983.2014/K, № 18.1369.2017/ПЧ)</funding-statement><funding-statement xml:lang="en">the Ministry of Education and Science of the Russian Federation (№ 18.1983.2014/K, № 18.1369.2017)</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">Florea V.G., Cohn J.N.
