  • VMI: ventricular mass index; PPV: positive predictive value; NPV: negative predictive value; LR: likelihood ratio; ROC AUC: receiver-operator characteristics area under the curve; TAPSE: transverse annular systolic excursion; SFD: septal-free wall distance; RVRAC: right ventricle area change; PA/Ao: pulmonary artery/aorta ratio.
