  1. The Full model includes total emboli volume, RV/LV ratio, MPA, MPA/AAO, chronic heart lung disease, age, gender, BNP, Troponin I, systolic blood pressure and respiratory rate as the factors. After backward stepwise selection, the remaining factors were total emboli volume, age, respiratory rate, and MPA.
  2. BNP B-type natriuretic peptide, RV right ventricle, LV left ventricle, MPA diameter of main pulmonary artery, AAO ascending aorta. * The threshold for statistical significance was p < 0.05.
