| 摘 要： | 目的运用定量组织速度成像技术(QTVI)测定肺动脉高压患者的右心Tei指数,与传统血流多普勒方法作对比性研究,探讨QTVI法测量Tei指数在临床评价右心功能的应用价值。方法入选病例:肺动脉高压患者91例,分为轻、中、重三组;正常对照组52例。分别利用脉冲血流多普勒成像(PW)和QTVI技术,测算研究对象的Tei指数。结果①QTVI和PW法所测肺动脉高压患者Tei指数均较正常对照组高,且差异有统计学意义。(PW法测得正常人与不同程度肺动脉高压患者Tei指数分别为0.28±0.07,0.29±0.12,0.48±0.14,0.70±0.30;QTVI法分别为0.32±0.10,0.41±0.15,0.56±0.13,0.84±0.21,P<0.05)。②QTVI与PW法所测研究对象的右室Tei指数相比,QTVI所测值均高于相对应的PW方法,(正常组0.32±0.10与0.28±0.07,肺高压组分别为0.41±0.15与0.29±0.12,0.48±0.14与0.56±0.13,0.70±0.30与0.84±0.2,P<0.05)差异均有统计学意义。③QTVI法测得Tei指数与肺动脉压力相关系数较PW高,评价右心功能的特异度及敏感度均较PW高(相关系数分别为r=0.71与r=0.61,评价心功能的敏感度分别为86.7%、75.9%;特异度为80.0%、65.5%)。结论利用QTVI测算Tei指数可准确评价心脏整体和局部功能,为评价肺动脉高压患者的右心功能提供了一种可靠的、无创性的、新的检测手段。
