Flow Chart of Patient Selection
All patients with diagnosed amyloidosis from 1998 to 2017 were identified in Danish nationwide registries. Cardiac amyloidosis (CA) was defined using a combination of International Classification of Diseases-10th Revision diagnosis and procedural codes. A total of 1,572 amyloidosis patients were identified, ∼40% of which met criteria for CA. CA, as defined in this study, is increasingly being diagnosed in Denmark.
