摘要
目的本文旨在探讨Tei指数在评价肺动脉高压患者右室功能中的作用,同时运用本指标探讨右室压力负荷增加对左室功能的影响。方法肺动脉高压患者21例,正常对照组24例,计算左、右室Tei指数。结果(1)与正常对照组相比,肺动脉高压患者右室IRT、ICT明显延长,ET明显缩短,导致右室Tei指数明显升高(P<0.00001);(2)与正常对照组相比,肺动脉高压患者左室IRT明显延长,ICT无显著差别,ET明显缩短,导致左室Tei指数明显升高(P<0.001)。结论(1)Tei指数是评价肺动脉高压患者右室功能简便而准确的多普勒超声新指标;(2)右室压力负荷增加对左室功能有明显影响。
Objective To determine the clinical value of Tei index in the assessment of right ventricular function in patients with pulmonary hypertension （PH） and the effect of right ventricular （RV） pressure overload on left ventricular （LV） function. Methods A total of 21 patients with PH and 24 normal subjects underwent Doppler echocardiographic examination including measurement of the Tel-indices. Results ① The RV IRT and ICT were significantly prolonged and ET significantly was shorted in the patients with PH compared with these in normal subjects, resulting in a marked increase of RV Tei indices （P〈0. 00001） different from normal values; ② The LV IRT was prolonged, the ICT showed no significant difference and ET was shortened in the patients with PH compared with these in normal subjects, resulting in a marked increase of LV Tei indices （P〈0. 001） from normal values. Conclusions The ① Tei index is a new simple and accurate Doppler index in assessing right ventricular function with PH;② right ventricular pressure overload due to PH has significant effects on LV function.
