[目的]探讨右室Tei指数评价慢性阻塞性肺病临床怀疑肺心病患者右室功能的价值。[方法]超声观察测量65例临床怀疑慢性肺源性心脏病患者及46例正常人常规超声指标,测量并计算右室Tei指数。超声测量指标包括右房横径、右室内径、右室前壁厚度、肺动脉主干内径、根据三尖瓣返流估测肺动脉收缩压。[结果]65例患者中25例具有较明确的肺心病超声征象,32例无明显二维超声改变但有不同程度肺动脉高压,8例患者无肺心病二维超声征象,又无三尖瓣或肺动脉瓣少量返流,多谱勒超声无法估测肺动脉压,超声诊断为正常超声心动图。上述3类患者右室Tei指数与对照组相比差异均有统计学意义。[结论]Tei指数的测量可为临床提供一定的诊断信息,对治疗、预后有一定的帮助。
[Objective] To evaluate the value of right ventricular Tei index in assessing right ventricular function in patients with chronic obstructive pulmonary disease (COPD). [Method] Ultrasonography was used to measure the routine ultrasound indexes of 65 patients with suspected chronic cor pulmonale and 46 normal controls. The Tei index of the right ventricle was measured and calculated. Ultrasound measurements include the right atrium diameter, right ventricular diameter, anterior wall thickness of the right ventricle, and the diameter of the pulmonary artery, and pulmonary artery systolic pressure was estimated from the tricuspid regurgitation. [Results] Twenty-five of the 65 patients had more definite signs of pulmonary heart disease, 32 patients had no obvious two-dimensional ultrasound changes but different degrees of pulmonary hypertension, 8 patients had no pulmonary heart disease two-dimensional ultrasound signs, and no tricuspid valve or A small amount of pulmonary valve regurgitation, Doppler ultrasound can not estimate pulmonary artery pressure, ultrasound diagnosis of normal echocardiography. There were significant differences in Tei index of right ventricle between the three groups above and the control group. [Conclusion] The measurement of Tei index can provide some diagnostic information for clinic, which will help to cure and prognosis.
