AO = aorta, APE = acute pulmonary embolism, LPA = left pulmonary artery, LVD = left ventricular maximal short diameter, MPA = main pulmonary artery, PAh = pulmonary artery height, PAOI = pulmonary artery occlusion index, PAV = pulmonary artery volume, RPA = right pulmonary artery, RVD = right ventricular maximal short diameter, RVD/LVD = maximal short diameter of the right and left ventricles, VSD = ventricular septal displacement, VCR = Vena cava reflux. P, comparison among 3 groups;
P < .05 compared with the control group;
P < .05 compared with patients with a good prognosis. Data were presented as mean ± standard deviation when they are in the normal distribution and as a median (interquartile range) when they are not in the normal distribution.
