Data are presented as n (%) or median±sd, unless otherwise stated. sPAP: systolic pulmonary arterial pressure; mPAP: mean pulmonary arterial pressure; dPAP: diastolic pulmonary arterial pressure; PAWP: pulmonary arterial wedge pressure; RAP: right atrial pressure; CO: cardiac output; CI: cardiac index; PVR: pulmonary vascular resistance; WU: Wood Units; DPG: diastolic pressure gradient (dPAP–PAWP).
