Phenotype and prognostic factors in geriatric and non‐geriatric patients with transthyretin cardiomyopathy

Abstract Aims Transthyretin cardiac amyloidosis (ATTR‐CM) may be an underestimated cause of heart failure among geriatric patients and represent a unique phenotype and prognostic profile. Methods and results This retrospective, observational, cohort study characterizes cardiac and extracardiac disorders at diagnosis and assesses prognosis among ATTR‐CM patients based on age (geriatric vs. non‐geriatric) and amyloidosis subtype (wild type, ATTRwt and hereditary, ATTRv). In total, 943 patients with ATTR‐CM were included, of which 306 had ATTRv and 637 had ATTRwt. Among these, 331 (35.1%) were non‐geriatric (
