A BNP of 1,000 is worth paying close attention to. To put it in context, here's how the cardiac staging system works for amyloidosis:
- Stage 1 — Both BNP and cTnI are in the normal range
- Stage 2 — One biomarker is elevated
- Stage 3 — Both BNP and cTnI are elevated
- Stage 3B — BNP is 700 or higher *and* cTnI is also Show Full Answer
A BNP of 1,000 is worth paying close attention to. To put it in context, here's how the cardiac staging system works for amyloidosis:
- Stage 1 — Both BNP and cTnI are in the normal range
- Stage 2 — One biomarker is elevated
- Stage 3 — Both BNP and cTnI are elevated
- Stage 3B — BNP is 700 or higher *and* cTnI is also elevated
A BNP of 1,000 would place you in at least Stage 3 territory if your cTnI is also elevated, or Stage 2 if cTnI is normal. Stage 3B is associated with a more serious outlook, so knowing your cTnI level alongside your BNP is really important. The good news is that wild-type amyloidosis tends to progress more slowly than other types, and newer treatments are helping people live longer, healthier lives. At 71, age is one factor doctors consider, but it's just one piece of the picture.
It's really important to discuss these numbers with your specialist so they can look at the full picture — your BNP, cTnI, and how you're feeling day to day — and adjust your treatment plan if needed. Don't hesitate to ask your doctor directly what your staging means for you.
