Tei指数对慢性阻塞性肺病的右室心功能评价

Evaluation of right ventricular function in chronic obstructive pulmonary disease with Tei index

目的Tei指数在慢性阻塞性肺病患者右心功能评价中的应用价值。方法将52例临床确诊为COPD患者设为实验组,设立正常对照组30例,超声测量并计算右室Tei指数,观察测量两组研究对象常规超声指标,包括右房横径、右室横径、右室前壁厚度、主肺动脉内径、肺动脉收缩压。结果52例患者中有16例具有典型肺心病心脏形态改变(A组),24例无典型右心形态改变,但合并有肺动脉高压(B组),12例无右心形态改变和肺动脉压增高(C组)。各组右室Tei指数与对照组相比差异有统计学意义,A组右室Tei指数与C组相比差异有统计学意义。结论右室Tei指数的测量可作为COPD患者右心功能评价的参考指标。

Objective To investigate the value of right ventrieular Tei index in chronic obstructive pulmonary disease. Methods 52 patients with chronic obstructive pulmonary disease and 30 volunteers were involved in this study. The traditional ultrasonic parameters included the right atrium horizontal path, the right ventricle horizontal path, the right ventricle anterior wall thickness, pulmonary main artery diameter, arterial systolic pressure and Tei index were measured. Results In 52 cases, there were 16 cases with obvious cardiopulmonary disease by ultrasound signs（A group）, 24 cases with pulmonary artery high blood pressure and without obvious ultrasound changes （B group）, and 12 cases without obvious ultrasound changes and pulmonary artery high blood pressure（C group）. The Tel index of right ventricle in the three groups was significantly different from the control. Conclusions Tel index is accurate and simple in estimating right ventricular function in chronic obstructive pulmonary disease.
