Questionnaire contained questions reflecting physicians’ awareness about treatment for improving the prognosis of patients with CHFrEF.</p></sec><sec><title>   Results</title><p>   Results. The quadruple therapy: sacubitril- valsartan (ARNI)/angiotensin- converting enzyme inhibitor /angiotensin II receptor blocker + beta-blocker (BB) + mineralocorticoid receptor antagonist (MRA) + sodium- glucose cotransporter type 2 inhibitor (SGLT2i) was named as an optimal treatment for CHFrEF by 63.3 % of doctors (71.6 % of cardiologists and 36.4 % of internists). 80 % of respondents (89 % of cardiologists and 50 % of internists) correctly pointed out the indications for ARNI, 75.4 % (83.9 % of cardiologists and 45.4 % of internists) — for therapy with BB, 71.0 % (80 % of cardiologists and 36.3 % of internists) — for prescribing AMR, and 76.8 % (86.4 % of cardiologists and 43.1 % of internists) — for using SGLT2i. 81.7 % of respondents (89.7 % of cardiologists and 52.3 % of internists) correctly named the target dose of BB, 45.9 % (51 % of cardiologists and 31.8 % of internists) indicated the neuromodulatory dose of AMR, and 74.3 % (83.9 % of cardiologists and 52.3 % of internists) correctly noted the recommended dapagliflozin dose (p &lt; 0,01 for all comparisons between groups of cardiologists and internists). Among the drugs that are most often used in everyday practice to improve the prognosis of symptomatic patients with CHFrEF, respondents named BB (66.2 %), MRA (58.5 %), angiotensin- converting enzyme inhibitor/angiotensin II receptor blocker (57 %), ARNI (37.7 %), and SGLT2i (45.4 %). Cardiologists use ARNI (p &lt; 0,01), SGLT2i (p &lt; 0,01), and MRA (p &lt; 0,05) more often than internists.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. Insufficient knowledge of physicians, especially internists, of the key provisions of clinical guidelines for CHFrEF pharmacotherapy can be considered as one of the reasons for suboptimal treatment.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>   Цель</title><p>   Цель. Выяснить знания врачей и их представления о терапии, влияющей на прогноз пациентов с хронической сердечной недостаточностью со сниженной фракцией выброса левого желудочка (ХСНнФВ).</p></sec><sec><title>   Материал и методы</title><p>   Материал и методы. Проведено анонимное анкетирование 207 врачей (155 кардиологов, 44 терапевтов, 8 врачей других специальностей), обучавшихся по программам повышения квалификации весной 2023 г. Анкета включала вопросы, отражающие представления врачей о терапии, направленной на снижение риска госпитализации из-за сердечной недостаточности и смерти пациентов с ХСНнФВ.</p></sec><sec><title>   Результаты</title><p>   Результаты. Оптимальным вариантом лечения ХСНнФВ 63,3 % опрошенных врачей (71,6 % кардиологов и 36,4 % терапевтов) назвали квадротерапию: сакубитрил-валсартан (ангиотензиновых рецепторов и неприлизина ингибитор, АРНИ) или ингибитор ангиотензинпревращающего фермента/блокатор рецепторов ангиотензина II + бета-адреноблокатор (БАБ) + антагонист минералкортикоидных рецепторов (АМКР) + ингибитор натрий- глюкозного котранспортера 2 типа (ИНГТ2). Верно указали показания к назначению АРНИ 80 % респондентов (89 % кардиологов и 50 % терапевтов), показания к терапии БАБ — 75,4 % (83,9 % кардиологов и 45,4 % терапевтов), показания к назначению АМКР — 71,0 % (80 % кардиологов и 36,3 % терапевтов), показания к применению ИНГТ2 — 76,8 % (86,4 % кардиологов и 43,1 % терапевтов). Правильно назвали критерии достижения целевой дозы БАБ 81,7 % респондентов (89,7 % кардиологов и 52,3 % терапевтов), нейромодулирующую дозу АМКР — 45,9 % врачей (51 % кардиологов и 31,8 % терапевтов), рекомендованную дозу дапаглифлозина — 74,3 % респондентов (83,9 % кардиологов и 52,3 % терапевтов). Для всех сравнений между группами кардиологов и терапевтов p &lt; 0,01. Среди препаратов, которые наиболее часто применяют для улучшения прогноза пациентов с ХСНнФВ II-IV функционального класса в собственной практике, респонденты указали БАБ (66,2 %), АМКР (58,5 %), ингибитор ангиотензинпревращающего фермента /блокатор рецепторов ангиотензина II (57 %), АРНИ (37,7 %), ИНГТ2 (45,4 %). Кардиологи чаще, чем терапевты, применяют АРНИ (р &lt; 0,01), ИНГКТ2 (р &lt; 0,01), АМКР (р &lt; 0,05).</p></sec><sec><title>   Заключение</title><p>   Заключение. Результаты исследования показали недостаточное знание врачами, особенно терапевтами, ключевых положений клинических рекомендаций по фармакотерапии ХСНнФВ, что может быть одной из причин субоптимального лечения пациентов с этой патологией.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>знания врачей</kwd><kwd>клинические рекомендации</kwd><kwd>приверженность</kwd><kwd>терапия</kwd><kwd>влияние на прогноз</kwd><kwd>анкетирование</kwd><kwd>обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic heart failure</kwd><kwd>physicians’ knowledge</kwd><kwd>clinical guidelines</kwd><kwd>adherence</kwd><kwd>treatment</kwd><kwd>prognosis</kwd><kwd>survey</kwd><kwd>training</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Санкт-Петербургского государственного университета</funding-statement><funding-statement xml:lang="en">The study was performed with the support of Saint-Petersburg State University</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">Tromp J, Ouwerkerk W, van Veldhuisen DJ, et al.
