    Abstract
  •   Objective  To investigate the diagnostic value of multi-slice spiral CT (MSCT) multiparameter in the risk stratification of acute pulmonary embolism (APE).  Methods  Seventy-four patients diagnosed with APE by MSCT in the First Affiliated Hospital of Bengbu Medical College between January 2019 and October 2020 were included, and the patients were divided into high-risk group (18 patients), medium-high risk group (26 patients) and medium-low risk group (30 patients) according to hemodynamic status, right ventricular function and whether the myocardium was damaged, and the differences in PAOI and other imaging parameters. Clinical and laboratory indices between the groups were compared, and the subject workup characteristic curves were used to evaluate the predictive value of PAOI and cardiovascular. The predictive value of PAOI and cardiovascular parameters for patients in the high-risk and medium-high risk group was evaluated using subject work characteristic curves, and independent risk factors for APE patients in the high-risk or medium-high risk group were analyzed using multivariate ordered logistic regression.  Results  Statistically significant differences were found in LDH, PAOI, PTD, PTD/AAD, RVD/LVD and involvement of pulmonary segmental arteries in different groups of patients (all P < 0.001). The sensitivity and specificity of PAOI (> 38.8%) for assessing patients at high-risk and medium-high risk of APE were 65.9% and 80.0%, and higher PAOI values are an independent risk factor for patients at high-risk or medium-high risk of APE (P < 0.001). The sensitivity and specificity of RVD/LVD (> 1.2) and PTD/AAD (>0.9) for assessing patients at high-risk and medium-high risk of APE were 59.1% and 93.3%, 65.9% and 86.7%, respectively.  Conclusion  MSCT multiparameter may be used to assess the severity and predict the progression of APE patients and guide clinical treatment.
