摘　　要：目的采用超声二维斑点追踪成像(STI)及组织多普勒(TDI)评价早期硬皮病(SSc)患者右心室功能。方法采用STI及TDI评价35例SSc患者(SSc组)及40名正常人(NOR组)的右心室游离壁基底段、中间段及心尖段应变。结果 STI与TDI均显示SSc组右心室游离壁基底段、中间段及心尖段应变均低于NOR组,差异具有统计学意义(P<0.05);STI与TDI所测应变显著相关(P<0.01)。结论 SSc患者右心室功能减低。STI及TDI均可评价SSc患者右心室功能。Objective To evaluate the right ventricular function with speckle tracking imaging（STI） and tissue Doppler imaging（TDI） in patients with systemic sclerosis（SSc）.Methods Thirty-five patients with SSc（SSc group）,and 40 healthy subjects（NOR group） were enrolled.Strain was performed using STI and TDI,the peak strain was calculated in the basal,middle and apical segments of right free wall.Results Compared with NOR group,peak strain parameters decreased in SSc group（P〈0.05）.Strong correlation was found between strain calculated with STI and TDI（P〈0.01）.Conclusion Right ventricular function decreases in patients with systemic scleroderma.STI and TDI may accurately evaluate right ventricular function.
