Определить дополнительные факторы, ассоциированные с промежуточной вероятностью сердечной недостаточности (ПВСН) с сохраненной фракцией выброса у бессимптомных пациентов в условиях арктической вахты, в т.ч. в гендерном аспекте.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В заполярном п. Ямбург (68° 21' 40" с.ш.) на базе МСЧ одномоментно обследовано 99 мужчин (М) и 81 женщина (Ж) с артериальной гипертонией (АГ) 1, 2 степени и нормотензивных лиц, сопоставимых по возрасту (р=0,450), северному стажу (р=0,956), уровню офисного систолического артериального давления (АД) (р=0,251), диастолического АД (р=0,579). Проведена эхокардиография, рассчитана вероятность наличия сердечной недостаточности с сохраненной фракцией выброса по шкале H2FPEF (Heavy; Hypertensive; Atrial Fibrillation; Pulmonary Hypertension; Elder; Filling Pressure) с подсчетом в баллах. Проведен тредмил-тест, расчет индекса Баевского с оценкой адаптационного потенциала к нагрузке, суточное мониторирование АД, биохимическое исследование крови.</p></sec><sec><title>Результаты</title><p>Результаты. В зависимости от числа баллов по шкале H2FPEF М и Ж разделены на группы: от 0 до 1 балла (группа 1 — норма), от 2 до 5 баллов (группа 2 — ПВСН). В группе М с ПВСН был выше индекс Баевского (р=0,0048), чаще регистрировался срыв адаптационных резервов организма (р=0,0394) в состоянии покоя, отмечен быстрый прирост АД в период дозированной физической нагрузки (ДФН) (р=0,0058) и снижение хронотропного резерва (р&lt;0,0001). Наличие АГ у М увеличивало шанс ПВСН в 3,6 раза, одышка на высоте ДФН в 10 раз, напряжение адаптации к нагрузке в 5 раз, наличие концентрического ремоделирования левого желудочка в 8-10 раз. В группе Ж с ПВСН чаще определялось состояние напряжения адаптации к нагрузке в покое (р=0,0120), отмечен меньший уровень потребления кислорода при ДФН (р=0,0485). Шанс выявления ПВСН у Ж увеличивался при дисфункции вегетативной нервной системы, увеличении среднесуточной вариабельности систолического АД, появлении одышки в период ДФН (в 10 раз), наличии концентрического ремоделирования левого желудочка и повышении маркеров неспецифического воспаления (высокочувствительный С-реактивный белок, IL-1β, IL-6).</p></sec><sec><title>Заключение</title><p>Заключение. Раннее выявление у бессимптомных пациентов с АГ дополнительных факторов риска ПВСН потенциально может снизить риск последующей клинической стадии сердечной недостаточности, что позволяет сосредоточить внимание на стратегиях профилактики и вмешательства в этой группе пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To determine additional factors and sex differences associated with the intermediate probability of heart failure (HF) with preserved ejection fraction (HFpEF) in asymptomatic patients working in the Arctic on a rotating basis.</p></sec><sec><title>Material and methods</title><p>Material and methods. In the polar village of Yamburg (68° 21' 40 "N), 99 men and 81 women with grade 1 and 2 hypertension (HTN) and normal blood pressure, comparable by age (p=0,450), length of service in the north (p=0,956), office systolic blood pressure (BP) (p=0,251), diastolic BP (p=0,579) were simultaneously examined. We performed echocardiography and assessed the risk of HFpEF by H2FPEF score (Heavy; Hypertensive; Atrial Fibrillation; Pulmonary Hypertension; Elder; Filling Pressure). A treadmill test, Baevsky index, 24-hour BP monitoring, and biochemical blood tests were performed.</p></sec><sec><title>Results</title><p>Results. Depending on H2FPEF score, participants were divided into groups: from 0 to 1 (group 1 — normal), from 2 to 5 (group 2 — intermediate probability of HFpEF). In men with intermediate probability of HFpEF, the Baevsky index (p=0,0048) and the incidence of resting body reserve dysaptation (p=0,0394) were higher, as well as a rapid BP increase during dosed exercise (p=0,0058) and a decrease in chronotropic reserve (p&lt;0,0001) were noted. The presence of HTN in men increased the intermediate probability of HFpEF by 3,6 times, dyspnea at dosed exercise by 10 times, dysaptation to exercise by 5 times, the presence of left ventricular concentric remodeling by 8-10 times. In females with intermediate probability of HFpEF, dysaptation to exercise at rest (p=0,0120) and lower level of oxygen consumption during dosed exercise was more often determined (p=0,0485). The intermediate probability of HFpEF in women increased with autonomic nervous system dysfunction, an increase in the mean 24-hour systolic BP variability, the presence of dyspnea during dosed exercise (10 times), concentric left ventricular remodeling, and an increase in nonspecific inflammation markers (high-sensitivity C-reactive protein, IL-1β, IL-6).</p></sec><sec><title>Conclusion</title><p>Conclusion. Early identification of additional risk factors for intermediate probability of HFpEF in asymptomatic hypertensive patients has the potential to reduce the risk of subsequent clinical heart failure, allowing focus on prevention and intervention strategies in this group of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>шкала  H2FPEF (Heavy</kwd><kwd>Hypertensive</kwd><kwd>Atrial  Fibrillation</kwd><kwd>Pulmonary Hypertension</kwd><kwd>Elder</kwd><kwd>Filling Preassure)</kwd><kwd>промежуточная  вероятность сердечной недостаточности  с сохраненной фракцией выброса</kwd><kwd>гендерные различия</kwd><kwd>арктическая вахта.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>H2FPEF score</kwd><kwd>intermediate probability of heart failure with preserved ejection fraction</kwd><kwd>sex differences</kwd><kwd>working in the Arctic</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">Brandt MM, Nguyen ITN, Krebber MM, et al.
