ABSTRACT
Objective:
To explore the value of quantitative parameters of CT pulmonary angiography in evaluating right heart function and prognosis of patients with central pulmonary embolism.Methods:
Clinical data of 200 patients with central pulmonary embolism were retrospectively analyzed, including 35 cases died (death group) and 165 cases survived (survival group) during hospitalization. The quantitative parameters of CT pulmonary angiography and right heart function were compared between 2 groups.Results:
Compared with the survival group, the pulmonary artery occlusion index, right ventricular short axis maximum diameter (RVSAMD), RVSAMD/left ventricular short axis maximum diameter (LVSAMD), pulmonary artery diameter in the death group all increased (all P< 0.001). There was no significant difference of LVSAMD between 2 groups (P=0.131). Multivariate Logistic regression analysis showed that CT pulmonary artery occlusion index, RVSAMD, RVSAMD/LVSAMD and increase of pulmonary artery diameter were the risk factors of death in patients with central pulmonary embolism (all P< 0.05). Pearson linear regression analysis showed that CT pulmonary artery occlusion index, RVSAMD/LVSAMD and pulmonary artery diameter were all positively correlated with RVSAMD (all P< 0.05).Conclusion:
The quantitative parameters of CT pulmonary angiography have certain value in predicting right heart function and prognosis of patients with central pulmonary embolism.
