摘要
目的探讨组织多普勒Tei指数评价慢性肺源性心脏病患者左心功能的临床价值。方法受试者分肺心病组(40例)和正常对照组(20例),常规超声心动图检查,测量左室射血分数(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及二尖瓣前环、后环组织多普勒Tei指数。结果肺心病组EF较正常组降低,差异显著,P<0.05;肺心病组A/E较正常组增高,差异显著,P<0.01;肺心病组二尖瓣环组织多普勒Tei指数较正常组显著增加,P<0.01。结论左室Tei指数是反映左心整体功能的敏感指标,组织多普勒Tei指数可综合评价肺心病患者的左心功能。
Objective To investigate the value of the Doppler tissue imaging Tei-index for estimating left ventricular function in patients with chronic pulmonary heart disease.Methods The subjects were divided into normal group（n= 20） and cor pulmonole group（n= 40）.EF,A/E and Doppler tissue imaging Tei-index of mitral annulus of cuspis anterior and cuspis posterior were measured in all subjects.Results EF of the cor pulmonole group was lower than that of the normal group,P0.05;A/E of the cor pulmonole group was higher than that of the normal group,P0.01;DTI Tei index of mitral annulus was significantly higher in the cor pulmonole group,P0.01.Conclusions Tei-index of the left ventricular could be a clinic sensitive value to evaluate the overall function of the left ventricular of patients.DTI Tei index could be used to assess left ventricular function in patients with chronic pulmonary heart disease.
