Prognosis is determined by the organ involved and by the involvement of the heart; cardiac amyloidosis (CA) leads to the worst evolution. CA may be due to myocardial deposition of the protein transthyretin, which is derived from liver tissue; this condition is known as ATTR. The other form of myocardial deposition is secondary to immunoglobulin light chain proteins, […]
