Patient flow chart. A total of 86 patients with a diagnosis of cardiac amyloidosis were screened for the NPU program; 73 patients were not eligible to participate. Exclusion criteria were a diagnosis of AL CA (n = 50), lack of baseline RHC (n = 11), NYHA FC I (n = 5), unwillingness to undergo follow-up RHC (n = 3), SBP < 100 mmHg (n = 2), immobility (n = 1), and one patient died before baseline evaluation. Thirteen patients were enrolled initially and two patients prematurely discontinued the NPU. Thus, 11 patients completed all study procedures. NPU, named patient use; RHC, right heart catheterization; NYHA, New York Heart Association; SBP, systolic blood pressure.
