Оценка группы пациентов со сниженным процентом стимуляции, болезненностью и влияние изменения программных настроек стимуляции на достижение положительного эффекта от модуляции сердечной сократимости (МСС).</p><p>Материал и методы исследования. В исследование включено 117 пациентов, которым было имплантировано МСС-устройство. Интраоперационно и после операции проводилась персонализация настроек. До имплантации и через 6 месяцев после операции проводилась трансторакальная эхокардиография.</p></sec><sec><title>Результаты </title><p>Результаты . Медиана возраста составила 59,5 лет, в 93,7% - пациенты мужского пола. Основной этиологией сердечной недостаточности являлась ишемическая болезнь сердца (53,8%). Части пациентов потребовалось снижение амплитуды стимуляции с 7,5 В (79%) максимально до 5 В (9%). Спустя 6 месяцев в группе с амплитудой стимуляции 7,5 В отмечался значимый прирост ФВ ЛЖ до 37 [32; 43] % (p=0,0001). При этом в группе с амплитудой стимуляции 5 В за время наблюдения увеличение ФВ ЛЖ не достигло статистически значимых величин 35 [34; 40] % (p=0,211). Пациенты без дискомфорта при проведении МСС-терапии имели более низкую ФВ ЛЖ (р=0,048), увеличенные объемы ЛЖ (р=0,024: р=0,034) и более тонкую заднюю стенку ЛЖ (р=0,028), однако, связь толщины стенок сердца и наличие болезненности при работе модулятора сердечной сократимости требует дальнейшего изучения. Также у пациентов с отсутствием дискомфорта от стимуляции электроды чаще были имплантированы в среднюю треть межжелудочковой перегородки (р=0,025). 83,7% пациентов было запрограммировано стандартное время стимуляции - 7 часов в сутки. У 5,9% время стимуляции составило от 10 до 14 часов в связи с недостижением необходимого процента стимуляции. В данной группе пациентов на фоне увеличения продолжительности терапии достигнута стимуляция свыше 70%. В 15,3% случаев у пациентов с МССустройством регистрировался процент терапии свыше 90. В 68,3% случаев процент терапии в сутки составлял 80-90 и в 12% - от 70 до 80%. Отмечалась положительная средняя значимая корреляция между процентом стимуляции и приростом ФВ ЛЖ (r=0,3; p=0,05).</p></sec><sec><title>Заключение</title><p>Заключение. МСС является эффективным методом интервенционного лечения пациентов с ХСН. При программировании МСС-устройств необходимо достижение 70% в сутки и более, так как процент стимуляции напрямую коррелирует с увеличением сократительной способности миокарда. Также амплитуда стимуляции должна достигать целевого уровня - 7,5 В. При возникновении болезненности допустимо снижение амплитуды стимуляции до минимально переносимой. Необходимо дальнейшее изучение нюансов работы прибора и обучение специалистов по программированию внутрисердечных устройств.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. Evaluation of a patient group with a reduced percentage of stimulation, pain sensation, and the impact of adjusting stimulation programming parameters on achieving a positive effect from cardiac contractility modulation (CCM) therapy.</p></sec><sec><title>Methods</title><p>Methods. The study included 117 patients implanted with a CCM device. Personalized parameter settings were programmed intraoperatively and postoperatively. Transthoracic echocardiography (TTE) was performed before implantation and 6 months after surgery.</p></sec><sec><title>Results</title><p>Results. The median age was 59.5 years, with 93.7% being male patients. The primary etiology of heart failure was ischemic heart disease (53.8%). A part of patients required a reduction in stimulation amplitude from 7.5 V (79%) to a maximum of 5 V (9%). After 6 months, the group with 7.5 V stimulation amplitude showed a significant increase in LVEF to 37 [32; 43] % (p=0.0001). However, in the group with 5 V stimulation amplitude, the increase in LVEF did not reach statistical significance during follow-up: 35 [34; 40] (p=0.211). Patients without discomfort during CCM therapy had lower LVEF (p=0.048), increased LV volumes (p=0.024; p=0.034), and a thinner LV posterior wall (p=0.028). However, the relationship between cardiac wall thickness and pain during ССМ therapy requires further research. Also, in patients without stimulation discomfort, the electrodes were more frequently implanted in the middle third of the interventricular septum (p=0.025). 83.7% of patients were programmed with standard stimulation duration - 7 hours per day (hrs/day). For 5.9%, the stimulation duration was 10 to 14 hours due to failure to achieve the required stimulation percentage. In this patient group, increasing the stimulation duration achieved a stimulation percentage exceeding 70%. In 15.3% of cases, patients with a CCM device had a therapy percentage above 90%. In 68.3% of cases, the daily therapy percentage was 80- 90%, and in 12% - 70 to 80%. A positive, moderate, significant correlation was noted between the stimulation percentage and the increase in LVEF (r=0.3; p=0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. CCM is an effective method of interventional treatment for patients with CHF. When programming CCM devices, it is necessary to achieve a stimulation percentage exceeding 70% per day, as the stimulation percentage directly correlates with an increase in myocardial contractility. Additionally, the stimulation amplitude should reach the target level of 7.5 V. If pain occurs, a reduction in stimulation amplitude to the minimum tolerable level is permissible. Further study of the nuances of device operation and training of specialists in programming intracardiac devices are necessary.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>модуляция сердечной сократимости</kwd><kwd>снижение процента стимуляции</kwd><kwd>болезненность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardiac contractility modulation</kwd><kwd>reduced stimulation percentage</kwd><kwd>pain sensation</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">Галявич АС, Терещенко СН, Ускач ТМ, и др.
