В настоящее время он приобрел характер эпидемии XXI века. В клиническом наблюдении описана история пациентки пожилого возраста, страдающей ишемической болезнью сердца (ИБС), дислипидемией, стенозирующим атеросклерозом брахиоцефальных артерий на фоне артериальной гипертензии (АГ), ожирения, сахарного диабета (СД) 2 типа, осложненного диабетической ретинопатией, полинейропатией, нефропатией с развитием хронической болезни почек (ХБП) и ХСНсФВ. Состояние отягощалось наличием хронического пиелонефрита единственной почки после нефрэктомии справа по поводу абсцесса почки, бронхиальной астмы. Продемонстрированы ограничения в использовании современных шкал для определения предтестовой вероятности ХСНсФВ, низкий показатель натрийуретических пептидов (НУП). Коморбидность, плохо контролируемые АГ, СД, низкая приверженность к терапии привели к развитию острой сосудистой катастрофы, повторное нарушение мозгового кровообращения — к летальному исходу. Гистологически обнаружен выраженный периваскулярный и интерстициальный склероз в миокарде и эпикарде, который является основой диастолической дисфункции при ХСНсФВ.Клинический пример отражает трудности диагностики ХСНсФВ, а также взаимное патогенетическое влияние сопутствующей патологии, что привело к неблагоприятному исходу при несоблюдении рекомендаций.</p></abstract><trans-abstract xml:lang="en"><p>Chronic heart failure with preserved ejection fraction (HFpEF) is a complex, heterogeneous, multi-organ systemic syndrome characterized by significant morbidity and mortality. Currently, it has acquired the character of an epidemic of the 21st century. The clinical observation describes a typical story of an elderly patient suffering from coronary artery disease (CAD), dyslipidemia, atherosclerosis of the brachiocephalic arteries against the background of arterial hypertension (AH), obesity, type 2 diabetes mellitus (DM), complicated by diabetic retinopathy, polyneuropathy, nephropathy with development of chronic kidney disease (CKD) and HFpEF. The condition was aggravated by the presence of chronic pyelonephritis of a single kidney (right nephrectomy for renal abscess in 2013), bronchial asthma. The limitations of modern scales for determining the pre-test probability of HFpEF and low natriuretic peptide levels are demonstrated. Comorbidity, poorly controlled hypertension, diabetes, low adherence to therapy led to the development of acute vascular accident, then, repeated cerebrovascular accident — to a fatal outcome. Histologically, perivascular and interstitial sclerosis in the myocardium and epicardium was detected, which is the basis of diastolic dysfunction in HFpEF.A clinical example reflects the difficulties of verification of HFpEF-diagnosis, as well as the mutual pathogenetic influence of concomitant pathology, which can lead to an unfavorable outcome if recommendations are not followed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая сердечная недостаточность</kwd><kwd>сохраненная фрак ция выброса</kwd><kwd>фиброз миокарда</kwd><kwd>коморбидность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic heart failure</kwd><kwd>preserved ejection fraction</kwd><kwd>myocardial fibrosis</kwd><kwd>comorbidity</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">Hamo CE, DeJong C, Hartshorne-Evans N. et al.
