摘　　要：目的　探讨 Tei指数评价肺心病患者左心功能的临床价值。方法　受试者分肺心病组 (2 0例 )和正常对照组 (2 0例 ) ,常规超声心动图检查 ,测量左室 EF、二尖瓣口血流舒张晚期 (A峰 )和舒张早期 (E峰 )峰值比 A/E及左室 Tei指数。结果　肺心病组 EF较正常组降低 ,差异显著 ,P<0 .0 1;肺心病组 A/E较正常组增高 ,差异显著 ,P<0 .0 1;肺心病组 Tei指数较正常组显著延长 ,P<0 .0 1。结论　 Tei指数可综合评价肺心病患者左心功能。Objective To investigate the value of the Tei index for estimating left ventricular function in patients with cor pulmonale.Methods The subjects were divided into normal (n) group(n=20) and cor pulmonale(c) group(n=20).EF,A/E and Tei index of the left ventricle were measured in all subjects.Results EF of the c group was lower than that of the n group,р<0.01;A/E of the c group was higher than that of the c group,р<0.01;Tei index was significantly higher in cor pulmonale,р<0.01Conclusions Tei index could be used to assess left ventricular function in patients with cor pulmonale.
