右室Tei指数对肺心病患者右心功能的评价

目的了解右心室Tei指数对肺心病患者右心功能的评价效果。方法使用Vivid E9多普勒超声诊断仪对50例肺心病患者及35例健康人进行超声心动图检查,测量右房横径（RA）、右室前后径（RV）、右室前壁厚度（RVAW）、肺动脉主干内径（MPA）、右室Tei指数,根据三尖瓣返流和肺动脉返流估测肺动脉收缩压（PASP）、舒张压（PADP）及平均压（PAMP）。结果肺心病组右房横径、右室前后径、右室前壁厚度、肺动脉主干内径、肺动脉收缩压、舒张压、平均压、Tei指数均大于对照组（P〈0.01）。结论右室Tei指数评价肺心病患者右心功能简便、实用、重复性高。

Right ventricular Tei index for evaluating right ventricular function in patients with pulmonary heart disease

Objective To observe the effect of right ventricular Tei index on right ventricular function in patients with pulmonary heart disease（PHD）.Methods Vivid E9 Doppler ultrasound was used to detect the right atrial diameter（RAD）,right ventricular diameter（RVD）,right ventricular anterior wall thickness（RVAWT）,pulmonary artery diameter（MPA）,and right ventricular Tei index in 50 PHD cases and 35 healthy controls.Pulmonary artery systolic pressure（PASP）,diastolic pressure（PADP） and mean pressure（PAMP） were assessed based on tricuspid and pulmonary regurgitation.Results RAD,RVD,RVAWT,MPA,PASP,PADP,PAMP,and Tei index were higher in PHD patients than those in controls（P〈0.01）.Conclusion Right ventricular Tei index is simple,feasible and reproducible for evaluating right ventricular function in PHD patients.
