Values are mean (standard deviation) followed by median (interquartile range). P-values are from Kruskal-Wallis test. PAPi is defined as pulmonary arterial pulse pressure divided by right atrial pressure.
mPAP, mean pulmonary arterial pressure; mRAP, mean right atrial pressure; PA, pulmonary artery; PAPi, pulmonary artery pulsatility index; PAWP, pulmonary arterial wedge pressure; PVR, pulmonary vascular resistance; RV, right ventricular; sPAP, systolic pulmonary arterial pressure; SVO2, venous oxygen saturation.
