Данный клинический случай демонстрирует неверифицированное амилоидозоподобное поражение сердца при наличии необъяснимого утолщения стенки недилатированного левого желудочка и проявлений сердечной недостаточности по рестриктивному типу у пациента с миеломной болезнью. Сложность установления точного диагноза заключается в существовании большого количества типов амилоидогенных белков, многообразии клинической картины, отсутствии патогномоничных симптомов и единого неинвазивного диагностического инструмента для верификации.</p></abstract><trans-abstract xml:lang="en"><p>The clinical case of cardiac pseudoamyloidosis associated with multiple myeloma Cardiac amyloidosis is an infiltrative cardiomyopathy resulting from extracellular deposition of amyloid- a specific protein-polysaccharide complex. This clinical case demonstrates an unverified amyloid-like heart lesion in the presence of unexplained thickening of the wall of an undilated left ventricle and manifestations of restrictive heart failure in a patient with myeloma. The difficulty of establishing an accurate diagnosis lies in the existence of a large number of types of amyloidogenic proteins, the diversity of the clinical picture, the absence of pathognomonic symptoms and of a single non-invasive diagnostic tool for verification.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>амилоидоз</kwd><kwd>амилоидоз сердца</kwd><kwd>ATTR</kwd><kwd>множественная миелома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amyloidosis</kwd><kwd>cardiac amyloidosis</kwd><kwd>ATTR</kwd><kwd>multiple myeloma</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">Garcia-Pavia P., Rapezzi C., Adler Y., Arad M., Basso C., Brucato A., Burazor I., Caforio A.L.P., Damy T., Eriksson U., Fontana M., Gillmore J.D., Gonzalez-Lopez E., Grogan M., Heymans S., Imazio M., Kindermann I., Kristen A.V., Maurer M.S., Merlini G., Pantazis A., Pankuweit S., Rigopoulos A.G., Linhart A.
