What are the stages of amyloidosis?

Stage I (TnI <0.1 ng/mL and NT-proBNP <332 pg/mL), stage II (TnI >0.1 ng/mL and NT-proBNP >332 pg/mL), and stage III (TnI >0.1 ng/mL and NT-proBNP >332 pg/mL). Stage I (TnI <0.1 ng/mL and BNP <81 pg/mL), stage II (TnI >0.1 ng/mL or NT-proBNP >81 pg/mL), and stage III (TnI >0.1 ng/mL and NT-proBNP >81 pg/mL).

Is amyloidosis a terminal?

Amyloidosis is sometimes fatal. Amyloid protein deposits, or amyloidosis, may be localized to organs, such as the lung, skin, bladder, or bowel, or they can be systemic. “Systemic” means that the deposits may be found throughout the body. Systemic amyloidosis is the most common.
