摘　　要：目的采用组织多普勒成像技术(TDI)测量三尖瓣环运动速度,用来评价尘肺患者的右室舒张功能,以此探讨组织多普勒成像技术对尘肺患者右室舒张功能的评价的临床价值。方法对30例尘肺患者进行超声心动图检查。选取超声心动图心尖四腔切面,应用组织多普勒成像技术测定右心室游离壁三尖瓣环处的运动速度峰值,测量包括舒张早期三尖瓣瓣环运动峰值速度Ve及舒张晚期三尖瓣瓣环运动速度峰值Va,计算Ve/Va。结果Ⅰ、Ⅱ期尘肺患者右室游离壁三尖瓣环处舒张早期三尖瓣瓣环运动峰值速度Ve与舒张晚期三尖瓣瓣环运动速度峰值Va比值Ve/Va同对照组无明显差异,而Ⅲ期尘肺患者室游离壁三尖瓣环处Ve/Va较对照组明显降低,有显著差异(P<0.05)。结论TDI技术定量三尖瓣环运动评估尘肺患者右室舒张功能,对于其治疗、疗效观察及预后评价具有重要意义。Objective To study the values of tissue doppler imaging(TDI)to estimate the diastolic function of right ventricular walls in the patients with coal workers pneumoconiosis.Methods 30 patients with coal workers pneumoconiosis are were examined by echocardiography.Tissue Doppler imaging(TDI)technique was used to measure peak flow velocity in early diastolic phase(Ve),peak flow velocity in late diastolic phase(Va)and ratio of Ve to Va(Ve/Va)Results There was no significant difference in Ve/Va between the first and the second phase of coal workers pneumoconiosis groups and the normal groups.In the third phase of coal workers pneumoconiosis groups,the Ve/Va was less than that in normal groups(P<0.05).Conclusions The diastolic function of right ventricular in the patients with coal workers pneumoconiosis can be estimates by TDI.
