Background: Current practice guidelines for patients with Pulmonary Arterial Hypertension (PAH) recommend a multidimensional risk assessment, but World Health Organization (WHO) Functional Class (FC) remains a main criterion for treatment decisions.
Objectives: A post hoc analysis was conducted to determine if different risk assessment tools evaluated in PAH registry populations can identify patients in WHO FC II at higher risk of death.
Methods: Patients in the randomized, controlled EARLY trial (NCT00091715; N=185), which exclusively enrolled patients in FC II, were stratified into three categories—low-, intermediate-, and high-risk—using the original REVEAL risk calculator, revised REVEAL risk calculator 2.0, COMPERA categorical score, and two FPHN methods (invasive and non-invasive) counting low-ris..
