Factors (such as peak oxygen consumption, 6‐minute walk distance, and natriuretic peptides) are predictors of mortality in nonamyloid HF.32–33 The biomarkers NT‐proBNP, troponin T, and TnI have been used as measures of prognosis and response to therapy for AL amyloidosis.31,34 In our study BNP and female sex and possibly TIMP‐1 were predictors for all‐cause death in cardiac amyloidosis patients. The gene discussed is NPPB; the disease is cardiac amyloidosis.
