NPPB and cardiac amyloidosis: Patients with cardiac amyloidosis had significantly higher NT-proBNP (p = 0.002) and higher hs-cTnT (p < 0.001), while the patients without cardiac amyloidosis had higher percentage of bone marrow plasma cells (p = 0.027), higher incidence of hemoglobin <80 g/L (p = 0.021) and bone destruction (p < 0.001).
