Figure 1 shows the probability of having ATTRwt amyloidosis in patients who have isolated cardiac amyloidosis without macroglossia or easy bruising with a detectable plasma cell dyscrasia in patients above or below 70 years of age according to the NT pro‐BNP at baseline. Patients ≤70 years old were more likely (P>0.5) to have ATTRwt than AL if the NT pro‐BNP was <183 pmol/L, and patients >70 years old with an NT pro‐BNP of <1420 pmol/L were more likely to have ATTRwt. Here, NPPB is linked to cardiac amyloidosis.
