Hemodynamic characteristics at the time of diagnosis of pulmonary hypertension.

Hemodynamic parameters

mean ± SD (range)


RAP, mmHg

8 ± 4 (2–16)

mPAP, mmHg

46 ± 11 (30–68)

PAWP, mmHg

8 ± 3 (2–14)

Cardiac index, L/min/m2

2.2 ± 0.6 (1–3.4)

SvO2, %

55.8 ± 8.5 (41–72)

PVR, dyn.s.cm-5

469 ± 275 (142–1183)

PVRI, dyn.s.cm-5/m2
