Predictive value of dual-source CT pulmonary angiography in risk stratification and prognosis of patients with acute pulmonary embolism
摘要
Abstract
Objective:To explore the predictive value of dual-source CT pulmonary angiography(CTPA)in risk stratification and prognosis of patients with acute pulmonary embolism(APE).Methods:A total of 152 patients with suspected APE were retrospectively analyzed and divided into the APE group(84 cases)and non-APE group(68 cases)according to clinical diagnosis results.And then the APE patients were divided into the low-risk group(45 cases)and high-risk group(39 cases)according to risk stratification.According to prognosis,the APE patients were divided into the good-prognosis group(59 cases)and poor-prognosis group(25 cases).All patients underwent dual-source CTPA examination.Univariate analysis and multivariate logistic regression analyses were performed to identify the risk factors associated with risk stratification and prognosis in APE patients.The ROC curve was used to evaluate the predictive performance of dual-source CTPA parameters for risk stratification and prognosis.Results:The ratio of right ventricular diameter to left ventricular diameter(RVD/LVD),main pulmonary artery diameter(MPAD),ratio of MPAD to aorta diameter(MPAD/AD),pulmonary artery obstruction index(PAOI)and ventricular septal displacement ratio in the APE group were higher than those in the non-APE group(all P<0.05).The age,RVD/LVD,MPAD,MPAD/AD and PAOI in the high-risk group were higher than those in the low-risk group(all P<0.05),and age,RVD/LVD,MPAD and PAOI in the poor-prognosis group were higher than those in the good-prognosis group(all P<0.05).The logistic regression analysis showed that age,RVD/LVD,MPAD and PAOI were the independent risk factors associated with risk stratification and prognosis of APE(all P<0.05).The ROC curves showed that the AUC values of risk stratification in APE predicted by RVD/LVD,MPAD,PAOI alone and combined were 0.801,0.790,0.738 and 0.888,respectively,and the AUC values of the prognosis were 0.797,0.811,0.808 and 0.870,respectively.Conclusions:The significant increase in dual-source CTPA-related parameters(RVD/LVD,MPAD and PAOI)in APE patients can be served as useful indicators for risk stratification and prognostic evaluation.The combination of the three parameters provides high predictive value for both risk stratification and prognosis in APE patients.关键词
