Обсуждаются варианты амилоидоза, при которых поражение сердца является частым: AL амилоидоз, ATTRwt и ATTRv амилоидоз. Описаны клинические признаки амилоидной кардиомиопатии, экстракардиальные проявления, позволяющие подозревать амилоидоз. Представлены методы диагностики амилоидной кардиомиопатии.</p><p>Эхокардиографические диагностические признаки включают увеличение толщины стенки левого желудочка, атриовентрикулярного клапана, стенки правого желудочка, утолщение межпредсердной перегородки, диастолическую дисфункцию и снижение общей продольной деформации при относительном сохранении продольной деформации верхушки.</p><p>Магнитно-резонансная томография позволяет выявить характерные для амилоидоза признаки: увеличение внеклеточного объема и диффузное субэндокардиальное или трансмуральное отсроченное контрастирование после введения гадолиния.</p><p>Сцинтиграфия с использованием препаратов, меченных технецием-99m, может подтвердить диагноз ATTR-кардиомиопатии. Диагноз ATTR-кардиомиопатии возможен только в сочетании с анализами крови и мочи для исключения наличия моноклонального белка. Скрининг на моноклональный белок включает 3 лабораторных теста: определение свободных легких цепей в сыворотке крови, электрофорез сывороточного белка и белка мочи с иммунофиксацией.</p><p>Обсуждаются показания для биопсии миокарда и роль биопсии экстракардиальных тканей. Эндомиокардиальная биопсия должна быть выполнена: а) если имеется высокое клиническое подозрение на амилоидоз сердца у пациента с моноклональным белком; б) если имеется высокое клиническое подозрение на сердечный амилоидоз, несмотря на отрицательный или двусмысленный результат сцинтиграфии; в) если сцинтиграфия сердца недоступна.</p><p>Обсуждаются возможности патогенетической терапии при ATTR и AL амилоидозе, направленной на прекращение или замедление отложения амилоида в сердце, симптоматическое лечение.</p></abstract><trans-abstract xml:lang="en"><p>The review presents current data on heart disease in systemic amyloidosis. The article discusses variants of amyloi-dosis with common heart disease: AL-, ATTRwt- and ATTRv amyloidoses. Clinical signs of amyloid cardiomyopathy and extracardiac manifestations that allow one to suggest amyloidosis are described. Methods for diagnosing amyloid cardiomyopathy are presented.Echocardiographic diagnostic characters include increased thickness of the left ventricular wall, atrioventricular valve, right ventricular wall, thickening of the interatrial septum, and also diastolic dysfunction, and decreased global longi-tudinal strain with relative preservation of apical longitudinal strain.Magnetic resonance imaging reveals signs specific for amyloidosis: increased extracellular volume and diffuse suben-docardial or transmural delayed enhancement after gadolinium administration.Scintigraphy using technetium-99m labeled compounds can confirm the diagnosis of ATTR cardiomyopathy. The diag-nosis of ATTR cardiomyopathy is only possible in combination with blood and urine tests to exclude the presence of a monoclonal protein. Screening for monoclonal protein includes three laboratory tests: determination of free light chains in blood serum, electrophoresis of serum protein and urine protein with immunofixation.Indications for myocardial biopsy and the role of extracardiac tissue biopsy are discussed. Endomyocardial biopsy should be performed: a) in case of strong clinical suggestion of cardiac amyloidosis in a patient with monoclonal pro-tein; b) in case of strong clinical suggestion of cardiac amyloidosis, despite negative or equivocal scintigraphy result; c) if cardiac scintigraphy is not available.The possibilities of pathogenetic therapy for ATTR- and AL amyloidosis, aimed at stopping or slowing amyloid deposi-tion in the heart, and symptomatic treatment are discussed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>амилоидоз</kwd><kwd>кардиомиопатия</kwd><kwd>транстиретин</kwd><kwd>легкие цепи иммуноглобулинов</kwd><kwd>рестриктивная кардиомиопатия</kwd><kwd>сердечная недостаточность.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amyloidosis</kwd><kwd>cardiomyopathy</kwd><kwd>transthyretin</kwd><kwd>light chains of immunoglobulins</kwd><kwd>restrictive cardiomyopathy</kwd><kwd>heart failure</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">Spanggaard M.B., Hansen C.T., Maiborg M. et al.
