The clinical case of cardiac pseudoamyloidosis associated with multiple myeloma

Abstract

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.
