[Modern conceptions of cardiac amyloidosis].

Cardiac amyloidosis is accumulation in the heart of a pathologic fibrillar protein amyloid. It represents a heterogeneous group of states from clinically insignificant amyloid accumulation in isolated atrial amyloidosis to severe involvement of the heart in primary amyloidosis when mean duration of life equals to 6 months. Insufficient awareness of physicians of this pathology leads to erroneous and belated diagnosis of cardiac amyloidosis. This paper contains contemporary data of pathophysiology, clinical manifestation, diagnosis, treatment, and prognosis of various variants of cardiac amyloidosis.
