摘　　要：目的:探讨影响CT肺动脉栓塞指数评价急性肺动脉栓塞右心功能不全的因素。方法:分析148例急性肺动脉栓塞患者CT肺动脉栓塞指数、基于栓子分布的肺血流量分布和更精确记分矫正的肺动脉栓塞指数、患者基本临床信息、超声右心功能不全的测量结果等数据,应用多因素Logistics回归分析和受试者特征曲线方法评价CT肺动脉栓塞指数在评价急性肺动脉栓塞右心功能不全的影响因素。结果:肺动脉栓塞指数、矫正后的栓塞指数、患者基础疾病是急性肺栓塞右心功能不全的影响因素(OR=2.83,3.13,4.07,P<0.05),联合矫正后的肺动脉栓塞指数、患者基础疾病对急性肺动脉栓塞所致右心功能不全具有更好的评价能力(AUC 0.9 VS 0.8,P<0.05)。结论:肺动脉栓子分布的血流量分布和更精确记分以及患者基础疾病会不同程度影响肺动脉栓塞指数对右心功能不全的评价。Objective:To indicate the influencing factors of CT pulmonary embolism index in evaluating right ventricular dysfunction in patients with acute pulmonary embolism.Methods:To analyze the CT pulmonary embolism index,pulmonary embolism index corrected by pulmonary blood flow of lobe functional contribution and accurate score,clinical information and cardiac ultrasound measurements of 148 patients,and to evaluate the influencing factors of CT pulmonary embolism index predicting right heart dysfunction using multivariate Logistics regression and receiver operating characteristic curve.Results:Pulmonary embolism index,pulmonary blood flow of lobe functional contribution and accurate score,and patients’underlying diseases are the influencing factors of right ventricular dysfunction in acute pulmonary embolism(OR=2.83,3.13,4.07,P<0.05).CT pulmonary embolism index combined with pulmonary blood flow of lobe functional contribution and patients’underlying diseases has better prediction ability for right ventricular dysfunction in acute pulmonary embolism(AUC 0.9 VS 0.8,P<0.05).Conclusion:Pulmonary blood flow of lobe functional contribution and accurate score,and patients’underlying diseases will affect the evaluation of pulmonary embolism index on right ventricular dysfunction.
