Most amyloid-forming proteins are relatively small, but otherwise there is currently no evidence of structural or functional similarities among proteins known to form disease-associated amyloids. One third of amyloid disease is hereditary, in which case there is normally an early age of onset. Half of amyloid-related diseases are sporadic and have a late age of onset – in these cases, the protein aggregation may be associated with aging-related decline in protein regulation. Some medical treatments are associated with amyloid disease, but this is rare. 1854:
of adverse events versus placebo. There is no evidence of an effect on mortality rate. A review of early data from use of patisiran in people with variant cardiac ATTR suggests that it may reduce mortality and hospitalization, however this is still being investigated and requires further investigation. In 2018, patisiran was not recommended by NICE in the UK for hereditary transthyretin-related amyloidosis. As of July 2019 further review however is occurring. It was approved for this use in the United States, however.

Immunofixation electrophoresis is more sensitive than regular electrophoresis but may not be available in all centers. Alternatively immunohistochemical staining of a bone marrow biopsy looking for dominant plasma cells can be sought in people with a high clinical suspicion for AL amyloidosis but negative electrophoresis. 371:, the heart shows a restrictive filling pattern, with normal to mildly reduced systolic function. AA amyloidosis usually spares the heart. Cardiac amyloidosis can present with symptoms of heart failure including shortness of breath, fatigue, and edema. As cardiac amyloidosis progresses, the amyloid deposition can affect the heart's ability to pump and fill blood as well as its ability to maintain normal rhythm, which leads to worsening heart function and decline in people's quality of life. 34: 1935:. AA amyloidosis is caused by an increase in extracellular deposition of serum amyloid A (SAA) protein. SAA protein levels can rise in both direct and indirect manners, through infection, inflammation, and malignancies. The most common causes of AA amyloidosis in the West are rheumatoid arthritis, inflammatory bowel disease, psoriasis, and 660:, which means a negative result does not exclude the diagnosis of amyloidosis. However, direct biopsy of the affected organ may still be unnecessary as other less invasive methods of biopsy can also be used, including rectal mucosa, salivary gland, lip, or bone marrow biopsy which can achieve a diagnosis in up to 85% of people. 3805: 1853:
