Combined prediction efficiency of arterial partial pressure of carbon dioxide combined with modified Geneva score on acute pulmonary embolism
Objective:To investigate the combined prediction efficiency of Partial pressure of carbon dioxide(PaCO2)and modified Geneva score on acute pulmonary embolism(APE).Methods:Clinical data of 265 suspected APE patients treated in our hospital from January 2019 to December 2022 were retrospectively analyzed.According to the results of computed tomography pulmonary angiography(CTPA)examination,265 patients were divided into APE group(CPTA positive)and Non-APE group(CPTA negative),among which 138 patients were in APE group and 127 patients were in Non-APE group.Clinical data of the two groups were collected and compared;and the combined prediction efficiency of PaCO2 and modified Geneva score was analyzed.Results:There were no significant differences in the distribution of dyspnea,hemoptysis,syncope and chest pain between APE group and Non-APE group.The distribution of modified Geneva scores in APE group was significantly higher than that in Non-APE group(P<0.05);patients with PaCO2<35mmHg in APE group were significantly more than those in Non-APE group(P<0.05).The predicted Area Under Curve(AUC)and 95%CI of PaCO2 combined with modified Geneva score for APE were higher than those of the single index.Conclusion:The AUC of PaCO2 combined with modified Geneva score is significantly higher than that of single index,its sensitivity is significantly better than that of modified Geneva score system alone,and its specificity is significantly better than that of PaCO2 alone.
