Data are presented as mean±sd, unless otherwise stated. #: these data include only those patients for whom the respective variables were available at baseline and at week 24; ¶: data missing at baseline for two patients; +: data missing at baseline for one patient. PVR: pulmonary vascular resistance; mPAP: mean pulmonary arterial pressure; RAP: right atrial pressure; SvO2 : mixed venous oxygen saturation; SVR: systemic vascular resistance; PAWP: pulmonary artery wedge pressure; SBP: systolic blood pressure; DBP: diastolic blood pressure.
