组织多普勒与脉冲多普勒测定系统性红斑狼疮患者右室Tei指数的对比研究

目的 利用组织多普勒成像(TDI)和脉冲多普勒成像(PD)测定系统性红斑狼疮(SLE)患者右室Tei指数,对比观察两种方法所测Tei指数的可行性和一致性.方法 对30例狼疮患者和30例健康志愿者分别进行组织多普勒和脉冲多普勒法测定右室Tei指数,并对两种方法所测Tei指数进行分析.结果 组织多普勒所测Tei指数与脉冲多普勒所测Tei指数具有良好相关性;病例组Tei指数与对照组Tei指数均存在显著差异(P<0.05);Tei-1与Tei-2之间无显著性差异(P>0.05).结论 两种方法所测Tei指数具有良好相关性,且组织多普勒敏感性略高; Tei指数能有效评价系统性红斑狼疮患者早期右室功能.

The comparison of using Tei index of PW-TDI and PW-PD to evaluate the function of right ventricular in patients with systemic lupus erythematosus

Objective To discuss the value of Tei index derived from wave-tissue Doppler(PW-TDI)and wave-pulsed Doppler(PW-PD)in evaluating right ventricular function in patients with systemic lupus erythematosus(SLE).Contrast to observe the feasibility and consistency of the two methods.Methods A total of 30 patients and 30 healthy volunteers were involved in this study.TDI-derived Tei index and PD-derived Tei index were measured and compared.Results The Tei index measured with TDI and PD had high relationships.Both the normal group and the SLE group had significant difference(P<0.05).And the Tei-1 and Tei-2 values had no signicant difference(P>0.05).Conclusion There was close correlation between the two methods and the PW-TDI have the better sensitivity.Tei index is valuable in evaluating the right ventricular function of the patient with SLE in the early time.
