Tei指数对HIV感染/AIDS患者右室功能的评价

目的 用组织多普勒（TDI）技术测量右心Tei指数评价HIV感染/AIDS患者右心功能并探讨Tei指数的临床价值.方法 162例HIV感染/AIDS患者作为病例组,另选择100例健康正常人作为对照组,常规做超声心动图检查得到右心构型数据：右室横径（RVD）、右房横径（RAD）,右室前壁厚度（RVAD）,并同时应用TDI技术在标准心尖四腔观获得三尖瓣环右室游离壁侧及室间隔侧TDI频谱图,计算出右心Tei指数,比较HIV感染组、AIDS组与正常对照组的Tei指数.结果 HIV感染者及AIDS患者Tei指数较对照组明显升高,并且AIDS患者Tei指数明显高于HIV感染者（P＜0.05）.结论 Tei指数是一个敏感、简便、快速评价HIV感染/AIDS患者右心整体功能的指标.

Tissue Doppler Tei Index for Estimation of the Right Ventricular Function in HIV/AIDS Patients

Objective To conduct a measurement of the right ventricular function in patients with HIV Infection/AIDS by applying pulsed wave tissue Doppler imaging （PW-TDI） for evaluation of the clinical value of pulsed Doppler Tei index.Methods 162 cases of HIV infection and AIDS patients were studied in this study,and another 100 healthy subjects were included as controls.Conventional echocardiography was performed in the total subjects to measure the configuration parameter of the right hearts,including right ventricular transverse diameter （RVD）,right atrium transverse diameter （RAD） and right ventricular anterior wall thickness （RVFW） as well as the spectral PW-TDI in the right ventricular free wall of tricuspid annulus side and septal side.the pulsed Doppler Tei indexes for the right ventricles were calculated and compared among the three groups.Results Tei indexes in the HIV infection and AIDS groups were higher than those in the control group.Tei indexes in the AIDS groups were higher than those in the HIV infection （P＜0.05）.Conclusion Pulsed Doppler Tei index may be sensitive,simple and quick marker for overall evaluation of the right ventricular function of HIV infection/AIDS.patients.
