  1. NYHA, New York Heart Association; BMI, body mass index; 6MWD, 6-minute walk distance; RAP, resting arterial pressure; mPAP, mean pulmonary arterial pressure; PASP, pulmonary artery systolic pressure; PCWP, pulmonary capillary wedge pressure; SaO2,oxygen saturation of arterial blood; SvO2, oxygen saturation of central venous blood; LVEF, left ventricular ejection fraction; PAR, pulmonary arteriolar resistance; CO, cardiac output.
  2. *Mean (SD), median (25th–75th/5th–95th percentile).
  3. Mann–Whitney U test for continuous parameters; maximal likelihood chi-square test or Fisher’s exact test for categorical parameters. P-value represents significance of NYHA FC between incident and prevalent cases.
