Note
Data are no. (%) of patients unless otherwise indicated. E/A: early to late mitral inflow ventricular filling velocities; IQR: interquartile range; LV: left ventricle; PAP: pulmonary artery pressure; PH: pulmonary hypertension; RV: right ventricle; SD: standard deviation; TAPSE: tricuspid annular plane systolic excursion.
a
Defined as mean PAP ≥25 and pulmonary capillary wedge pressure <15.
