Оценка долгосрочного прогноза пациентов хронической сердечной недостаточностью и сниженной фракцией выброса левого желудочка (СНнФВ), получающих модуляцию сердечной сократимости (МСС), в фокусе влияния бремени коморбидности на исходы.Материал и методы исследования. Включено 59 пациентов с СНнФВ II/III функционального класса (ФК), синусовым ритмом, которым были имплантированы устройства МСС с сентября 2015 года по декабрь 2018 года. Наблюдение осуществлялось мультидисплинарной командой. Средний период наблюдения составил 1916±102 дней. В качестве первичной комбинированной конечной точки (ККТ) рассматривали смерть от всех причин и трансплантацию сердца (ТС). Вторичная ККТ включала смерть от всех причин, ТС, срабатывания имплантированного кардиовертера-дефибриллятора по причине желудочковых тахиаритмий и госпитализации в связи с декомпенсацией сердечной недостаточности (СН). Вероятную выживаемость (ВВ) вычисляли по шкалам MAGGIC (ВВMAGGIC) и SHFM (ВВSHFM). Исходно для всех пациентов рассчитывали индекс коморбидности Чарлсона (ИКЧ).Результаты. Трехи пятилетняя выживаемость составили 79,7% и 66,1%, соответственно, и была выше, чем ВВ MAGGIC(p=0,02) и ВВSHFM (p=0,01). Среднее время до наступления первичной ККТ составило 1494 дня при годовой смертности 7%. Пациенты с СН III ФК, хронической болезнью почек и ИКЧ≥7 баллов имели худший прогноз (р1=0,002, р2=0,003, р3=0,04 (log-rank test). Регистрировалось значимое снижение количества госпитализированных пациентов по причине декомпенсации СН на фоне МСС терапии (р˂0,001) по сравнению с шестимесячным периодом до постановки кардиомодулирующего устройства. Пациенты со значением ИКЧ≥7 баллов быстрее достигали вторичной ККТ (р=0,002 и р=0,004 для трехлетнего и пятилетнего периодов наблюдения соответственно (log-rank test).Заключение. Показатели долгосрочной выживаемости пациентов СНнФВ II/III ФК на фоне применения МСС, курируемых мультидисциплинарной командой, были достоверно большими, чем расчетные. Полученные данные подтверждают негативный вклад выраженной коморбидности в клиническое течение и исходы СН на фоне МСС. Применение ИКЧ при комплексной оценке прогноза и идентификации таргетной популяции для использования дорогостоящих имплантируемых устройств, включая МСС, может быть полезным инструментом в стратификации рисков и алгоритмах принятия решения.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To investigate the association between comorbidity burden and long-term clinical outcomes of patients with reduced left ventricular ejection fraction (HFrEF) undergoing cardiac contractility modulation (CCM).</p></sec><sec><title>Methods</title><p>Methods. Our study included 59 patients with HFrEF, functional class II/III (NYHA), sinus rhythm, who underwent implantation of CCM system between September 2015 and December 2018 and were further followed by a multidisciplinary team. A mean follow-up period was 1916±102 days. All-cause mortality and heart transplantation were considered as primary composite endpoint. The secondary composite endpoint included all-cause mortality, heart transplantation, im- plantable cardioverter defibrillator shocks due to ventricular tachyarrhythmia and hospitalizations due to decompensated HF. Predicted survival rate were calculated using MAGGIC Risk Calculator and Seattle Heart Failure Model (SHFM). Initially, the Charlson comorbidity index (CCI) was calculated for all patients.</p></sec><sec><title>Results</title><p>Results. Three- and five-year survival rates were 79,7% and 66,1%, respectively, which were significantly higher than predicted by MAGGIC (p=0.02) and SHFM (p=0.01). The median time to the primary endpoint was 1494 days and the annual mortality was 7%. Patients with HF NYHA class III, chronic kidney disease and CCI ≥7 points had worse prognosis (p1=0.002, p2=0.003, p3=0.04 (log-rank test). There was a significant decrease in number of hospitalized pa- tients due to HF decompensated during CCM (p˂0.001) compared with the six-month period before the system implantation. Patients with CCI value ≥ 7 points reached secondary composite endpoint faster (p=0.002 and p=0.004 for three-year and five-year follow-up periods, respectively (log-rank test)).</p></sec><sec><title>Conclusion</title><p>Conclusion. Long-term survival rates of patients with HFrEF II/III (NYHA) receiving CCM and managed on multidisciplinary team were significantly higher than predicted. The heavy comorbidity burden negatively impacts on the clinical course and outcomes of HF patients following CСM implantation. Applying the Charlson index can be useful in a comprehensive assessment of the prognosis and determining the target population for the expensive implantable devices, including CCM, in risk stratification and decision-making algorithms.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>модуляция сердечной сократимости</kwd><kwd>прогноз</kwd><kwd>коморбидность</kwd><kwd>индекс коморбидности Чарлсона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic heart failure</kwd><kwd>cardiac contractility modulation</kwd><kwd>prognosis</kwd><kwd>comorbidity</kwd><kwd>Charlson comorbidity  index</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">Heidenreich PA, Bozkurt B, Aguilar D, et al. 2022 AHA/ ACC/HFSA Guideline for the Management of Heart Failure: A Report of the American College of Cardiology/American Heart Association Joint Committee on Clinical Practice Guidelines.
