Demographic and hemodynamic characteristics of PAH patients (case) and normal subjects (control).
| Variables | Case (n = 460) | Control (n = 530) | p |
|---|---|---|---|
| age (years) | 44.6 ± 13.9 | 45.4 ± 13.6 | 0.861 |
| sex | 0.853 | ||
| male | 135 (29.3%) | 163 (30.8%) | |
| female | 325 (70.7%) | 367 (69.2%) | |
| BMI (kg/m2) | 25.6 ± 4.5 | 25.1 ± 5.3 | 0.399 |
| 6MWD (m) | 247.9 (146.2–363.3) | ||
| NT-proBNP (pg/mL) | 1139.9 (360.9–2471.8) | ||
| mPAP (mmHg) | 51 (40–59) | ||
| PVRI (dyn*sec*m2/cm5) | 1485.2 (1137.3–2742.7) | ||

Data are presented as mean ± SD or median (interquartile range). BMI: body mass index; 6MWD: 6-min walk distance; NT-proBNP: N-terminal pro brain natriuretic peptide; mPAP: mean pulmonary arterial pressure; PVRI: pulmonary vascular resistance index; CO: cardiac output; CI: cardiac index.
