Parameters of pulmonary artery and right ventricle after indexing to the body surface area.
| Variables | Control (n = 61) | APE (n = 227) | P | |
|---|---|---|---|---|
| Good prognosis (n = 195) | Poor prognosis (n = 32) | |||
| MPA/AO | 0.43 (0.09) | 0.47 (0.11)* | 0.49 (0.11)* | .001 |

| MPA (cm/m²) | 1.45 (0.32) | 1.66 (0.43)* | 1.68 (0.34)* | ＜.001 |
| RPA (cm/m²) | 1.18 ± 0.18 | 1.31 ± 0.25* | 1.35 ± 0.19* | ＜.001 |
| LPA (cm/m²) | 1.14 (0.19) | 1.17 (0.24) | 1.28 (0.25)*# | .003 |

| RVD/LVD | 0.61 (0.21) | 0.63 (0.27) | 0.80 (0.42)*# | ＜.001 |
AO = aorta, APE = acute pulmonary embolism, LPA = left pulmonary artery, LVD = left ventricular maximal short diameter, MPA = main pulmonary artery, PAh = pulmonary artery height, 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.
