Overview
Natural History, Complications, and Prognosis
Natural History
- In amyloidosis, insoluble fibrils of amyloid are deposited in the organs, causing organ dysfunction and eventually death.[1]
- Wild-type (senile) amyloidosis, as the name suggests, is a disease of the elderly.
- The clinical picture of the disease corresponds to the type of organ or organ system involved.
- It most commonly affects the heart and hence, clinical features pertaining to cardiac pathologies, dominate the clinical course of the disease.
- The deposition of transthyretin (TTR) in the heart causes it to start functionally failing.
- The constellation of signs and symptoms of a TTR affected heart can mimic heart failure due to old age, and can thus mask the systemic involvement of wild-type (senile) amyloidosis.
- If left untreated, wild-type (senile) amyloidosis can lead to heart failure with reduced ejection fraction (HFrEF) and eventually death.
