CT肺动脉栓塞指数评价急性肺栓塞患者右心功能

Evaluation of Right Ventricular Function in Patients with Acute Pulmonary Embolism by CT Pulmonary Embolism Index

目的:研讨急性肺栓塞患者CT肺动脉栓塞指数与右心功能间的关联及价值。方法:采用螺旋CT对患者进行RVTD、RVAWTd、RVLD、RATD、RVEDV、RVESV等右心结构指标检测,同时采集患者血液检测BNP、NT-proBNP、cTnI、PaO2等心功能生物学指标。对比不同CT肺动脉栓塞程度的患者各指标间的差异。结果:RVTD、RVAWTd、RVLD、RATD、RVEDV、RVESV、BNP、NT-proBNP、cTnI、PaO2等指标B组与A、C两组均存在明显差异(P<0.05)。结论:急性肺栓塞患者CT肺动脉栓塞指数越高右心结构数值差异越大,右心功能异常越严重,可为判断患者右心功能提供诊断依据。

Objective:To investigate the correlation between CT pulmonary embolism index and right ventricular function in patients with acute pulmonary embolism.Methods:Spiral CT was used to detect rvtd,rvawtd,rvld,ratd,rvedv,rvesv and other indexes of right heart structure,and blood samples were collected to detect BNP,NT proBNP,cTnI and PaO2.Objective to compare the differences of different CT pulmonary embolism patients.Results:there were significant differences in rvtd,rvawtd,rvld,ratd,rvedv,rvesv,BNP,NT proBNP,cTnI and PaO2 between group B and group A and C(P<0.05).Conclusion:the higher the pulmonary embolism index,the greater the difference of right heart structure value and the more serious right heart function abnormality in patients with acute pulmonary embolism.
