Aims
Cardiac transthyretin (ATTR) amyloidosis is an increasingly recognized, progressive, and fatal cardiomyopathy, the natural history of which remains unclear. We sought to establish and validate a new prognostic staging system applicable to patients with both wild-type ATTR (ATTRwt) and hereditary variant ATTR (ATTRv) amyloid cardiomyopathy.
Methods and results
Eight hundred and sixty-nine patients with cardiac ATTR amyloidosis (553 with ATTRwt and 316 with ATTRv) attending the UK National Amyloidosis Centre were stratified into three disease stages at baseline on the basis of cut points in two universally measured biomarkers, N-terminal pro-B-type natriuretic peptide (NT-proBNP) and estimated glomerular filtration rate (eGFR). Stage I was defined as NT-proBNP ≤3000 ng/L and eGFR ≥45 ml/min, Stage III was defined as NT-proBNP >3000 ng/L and eGFR |
