Objective. To evaluate the efficiency of radiofrequency denervation of the renal arteries in patients with resi-stant arterial hypertension during a three-year follow-up. Materials and methods. The study involved 40 patients with resistant arterial hypertension aged 27 to 70 years (mean age 54.91±9.77 years) while receiving three or more antihypertensive drugs (including diuretic) in optimal doses. The conditions for inclusion in the study were considered resistant arterial hypertension with blood pressure (BP)>160/100 mm Hg, intact kidney function - glomerular filtration rate (MDRD)>45 ml/min - and the absence of secondary hypertension. All patients had sympatic radiofrequency denervation of renal arteries; its efficiency later was estimated according to the clinical measurement and ambulatory blood pressure monitoring (ABPM). Results. The level of office BP reliably differed initially and after 3 years: DSBP -34.48±6.44 mm Hg (p=0.001), DDBP - 22.29 mm Hg (p=0.001). According to ABPM results, reliable dynamics of systolic blood pressure was not observed. The data of DBP at night were significantly lower after 36 months; DDBP was -5.37±9.77 mm Hg. Conclusions. A marked decrease in the data of office SBP and DBP was observed, which proves the long-term efficiency of radiofrequency denervation of the renal arteries in patients with resistant hypertension. Accor-ding to ABPM results after 36 months, a significant decrease was registered among the DBP indicators at night and daytime.
Coronavirus disease 2019 (COVID-19) affects the function of all organs and systems. Today, studying the effect of COVID-19 on cardiovascular system, including on echocardiographic characteristics, is relevant.Aim. To study the prevalence of symptoms, cardiovascular disease and changes in echocardiographic data in persons after documented COVID-19 pneumonia 3 months after discharge from the hospital.Material and methods. The study included 106 patients after documented COVID-19 pneumonia. The patients underwent a comprehensive examination during hospitalization and 3 months±2 weeks after discharge from the hospital. The mean age of participants was 47±16 years (19-84 years); 49% of subjects were women.Results. Three months after hospital discharge, the symptoms persisted in 86% of examined patients. There were significant echocardiographic changes as follows: a decrease in LV end-diastolic, end-systolic and stroke volume (113,8±26,8 ml vs 93,5±29,4 ml; 37,7±13,0 ml vs 31,3±14,2 ml; 77,2±17,8 ml vs 62,2±18,7 ml, respectively, p<0,001 for all). The right ventricular anteroposterior dimension and the pulmonary trunk diameter decreased over time (26,0 [24,0-29,3] mm vs 25,0 [23,0-27,0] mm, p=0,004; 21,7±3,6 mm vs 18,7±2,5 mm, p<0,001), the same as the pulmonary artery systolic pressure, estimated by tricuspid regurgitation gradient (28,0 [25,0-32,25] mm Hg vs 21,5 [17,0-25,0] mm Hg). The right atrial volume (42,0 [37,0-50,0] m><0,001), the same as the pulmonary artery systolic pressure, estimated by tricuspid regurgitation gradient (28,0 [25,0-32,25] mm Hg vs 21,5 [17,0-25,0] mm Hg). The right atrial volume (42,0 [37,0-50,0] ml vs 31,0 [22,0-36,5] ml, p<0,001) a><0,001) and maximum width (36,1±4,6 mm vs 34,5±6,5 mm, p=0,023) decreased, while the right atrial maximum length increased (46,7±6,8 mm vs 48,6±7,1 mm, p=0,021).Conclusion. In survivors of COVID-19 pneumonia three months after hospital discharge, complaints persisted in 86% of cases. Cardiovascular diseases were detected in 52% of participants, including hypertension in 48,1% and coronary artery disease in 15,1%. Compared with in-hospital data, the echocardiographic characteristics improved, which was expressed mainly in a decrease in right heart load.
Тюменский кардиологический научный центр, Томский национальный исследовательский медицинский центр Российской академии наук, Томск, Россия Цель. Изучить клинические и эхокардиографические показатели, ассоциирующиеся с тромбообразованием ушка левого предсердия (УЛП), и выявить независимые предикторы тромбоза УЛП у пациентов с неклапанной фибрилляцией предсердий (ФП) перед планируемой катетерной аблацией (КА) или кардиоверсией. Материал и методы. Выполнен ретроспективный анализ данных 638 пациентов с неклапанной ФП, направленных на госпитализацию с 2014 по 2017 гг для проведения КА или кардиоверсии. Всем больным проводилось клинико-инструментальное обследование, в том числе трансторакальная и чреспищеводная эхокардиографии (ЧпЭхоКГ). Результаты. По данным ЧпЭхоКГ пациенты были разделены на 2 группы: группа 1-44 больных (7%) с наличием тромбоза УЛП и группа 2-594 (93%) без признаков тромбоза УЛП. Пациенты группы 1 имели более высокий риск по шкале CHA 2 DS 2-VASc, у них чаще встречались: ишемическая болезнь сердца, артериальная гипертония, хроническая сердечная недостаточность стадии IIA, ожирение ≥II степени, персистирующая форма ФП. Пациенты обеих групп не различались по приему антикоагулянтной терапии. У пациентов с тромбозом УЛП отмечались больший диаметр левого предсердия и правого желудочка, больший объем правого предсердия, конечно-систолический и конечно-диастолический диаметры левого желудочка (ЛЖ), у них наблюдались более высокий индекс массы миокарда ЛЖ, более низкие значения фракции выброса ЛЖ и скорости кровотока в УЛП. С помощью логистической регрессии были выявлены такие независимые предикторы тромбоза УЛП, как наличие выраженного ожирения ≥II степени (ОШ 2,75; 95% ДИ 1,33-5,68; p=0,006), персистирующая форма ФП (ОШ 2,31; 95% ДИ 1,07-4,99; p=0,033), увеличение диаметра левого предсердия (ОШ 1,13; 95% ДИ 1,03-1,24; p=0,009), наличие эксцентрической гипертрофии ЛЖ (ОШ 3,13; 95% ДИ 1,04-9,40; p=0,042). Заключение. Таким образом, в нашем исследовании были определены независимые предикторы развития тромбоза УЛП у пациентов с неклапанной ФП, включающие клинические факторы (ожирение и персистирующая форма ФП) и эхокардиографические параметры (диаметр левого предсердия и эксцентрическая гипертрофия). Ключевые слова: тромбоз ушка левого предсердия; фибрилляция предсердий; чреспищеводная эхокардиография Конфликт интересов: все авторы заявляют об отсутствии конфликта интересов.
stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?
