【摘要】：目的运用右室侧壁三尖瓣环组织多普勒TDI-Tei指数评价肺动脉高压患者右心室功能。方法 30例健康者作为对照组,90例肺动脉高压患者依肺动脉压程度分为轻、中、重度3个亚组,各30例,超声常规测量右心室横径、右心房横径、肺动脉主干内径,下腔静脉呼吸动度,并测量三尖瓣前叶瓣环的组织多普勒频谱,测量其右室Tei指数,进行比较分析。结果肺动脉高压轻、中、重组患者右心结构及肺动脉出现渐进性重构,右心室Tei指数敏感地反映肺动脉压力及右心功能变化。结论肺动脉高压患者右心室Tei指数升高,右心室整体功能降低,且与肺动脉收缩压相关。TDI-Tei指数可以灵敏地反映肺动脉高压患者右心室功能的变化,是评价其右心室整体功能的较好指标。
[Abstract]:Objective to evaluate the right ventricular function in patients with pulmonary hypertension by using right ventricular lateral wall tricuspid annular tissue TDI-Tei index. Methods 90 patients with pulmonary hypertension as control group were divided into three subgroups according to the degree of pulmonary artery pressure: mild, moderate and severe. The transverse diameter of the right ventricle, the transverse diameter of the right atrium, the diameter of the main pulmonary artery, the respiratory motility of the inferior vena cava, and the tissue Doppler spectrum of the anterior lobe annulus of the tricuspid valve were measured, and the Tei index of the right ventricle was measured. Results there were progressive remodeling of right heart structure and pulmonary artery in patients with mild and moderate pulmonary hypertension. The Tei index of right ventricle is sensitive to the changes of pulmonary artery pressure and right heart function. Conclusion the Tei index of right ventricle increases and the whole function of right ventricle decreases in patients with pulmonary hypertension. TDI-Tei index associated with pulmonary artery systolic pressure can reflect the changes of right ventricular function in patients with pulmonary hypertension and is a good index to evaluate the global function of right ventricle.
