Table 2 data are expressed as number and (percentage) or median and [interquartile range].

mPAP, mean pulmonary artery pressure; PCWP, pulmonary capillary wedge pressure; CI, cardiac index; mRAP, right atrial pressure; LV-EDV, left-ventricular end-diastolic volume; FE, ejection fraction; E/A ratio, refers to the ratio of the early (E) to late (A) ventricular filling velocities; FAC, fractional area change; TAPSE, tricuspid annular plane systolic excursion; sPAP, pulmonary artery systolic pressure.
