摘要
目的探讨应用组织多普勒成像技术(TDI)检测二尖瓣环6个节段运动速度,评估皮肌炎患者左室舒张功能的应用价值。方法应用TDI技术,对27例皮肌炎患者和21例正常对照者二尖瓣环6个节段舒张期运动速度进行测定,并与常规超声心动图检查结果进行对照分析。结果常规超声心动图测量参数中,皮肌炎患者舒张早期峰值血流速度(E)升高、舒张晚期峰值血流速度(A)降低、舒张早期与舒张晚期峰值血流速度之比(E/A)增大(P<0.05)。TDI二尖瓣环6个节段测量的舒张早期峰值速度(Ea)、舒张早期与舒张晚期峰值速度之比(Ea/Aa),不论E/A呈何种改变均明显降低。结论TDI技术测定二尖瓣环舒张期运动速度可以无创性的评估皮肌炎患者左室舒张功能。
[ Objective ] To evaluate the application value of tissue Doppler imaging （TDI） being used to evaluate left ventricle （LV） diastolic function in patients with dermatomyositis（DM） by detecting the 6 segments velocity of mitrails annulus motion. [Methods] 27 patients with DM and 21 normal controls were studied with TDI, the 6 segments velocity in relaxing period of mitralis annulus motion were detected, and detected with the pulse wave dopple （PW）, the related datas were compared with those of the control group. [ Results ] Compared with the normal control, for patients with DM, in PW datas, tile early-diastolic peak velocity（E） was increased, late-diastolic peak velocity（A） was decreased and ratio of E and A （E/A） was increased （P 〈0.05）. but in TDI darns, early-diastolic peak velocity （Ea） and ratio of Ea and Aa （Ea/Aa） of the 6 segments velocity in relaxing period of mitralis annulus motion was decreased obviously in patients with DM. Even if E/A was increased or not. [ Conclusions ] TDI can be used to evaluate the LV diastolic function in patients with DM by detecting the segments velocity in relaxing period of mitralis annulus motion without wound.
