Values are given as mean±SD or numbers (percentage) as required. BMI indicates body mass index; BSA, body surface area; CI, cardiac index; CO, cardiac output; DBP, diastolic blood; dPAP, diastolic pulmonary artery pressure; LOA, limits of agreement; mPAP, mean pulmonary artery pressure; mRAP, mean right atrial pressure; PAH, pulmonary arterial hypertension; PCWP, pulmonary capillary wedge pressure; PVR, pulmonary vascular resistance; RAP, right atrial pressure; SBP, systolic blood pressure; sPAP, systolic pulmonary artery pressure.
