WebJan 23, 2024 · Blacks/Hispanics with heart failure due to transthyretin cardiac amyloidosis will be identified by 99mTc-PYP (or 99mTc-HDP) scintigraphy. Those with transthyretin cardiac amyloidosis will be further subtyped into those with a genetic cause (ATTRm) and those with a non-genetic cause (ATTRwt - wild type transthyretin cardiac amyloidosis). WebAmyloidosis is caused by an abnormal folding of proteins. These proteins can clump together and form amyloid deposits. The deposits collect in organs and tissues and may lead to organ damage and health problems, including kidney disease.
