  1. R2 adjusted coefficient of determination.
  2. Model 1 included age, NYHA II, TRPG at low workload, ejection fraction at rest, and e′ at rest.
  3. Model 2 included all variables in Model 1 with stepwise multiple regression analysis.
  4. NYHA New York heart association, TRPG tricuspid regurgitation pressure gradient.
