摘　　要：目的探讨应用超声二维斑点追踪成像技术(STI)及组织多普勒技术(TDI)早期评价系统性红斑狼疮(SLE)患者右心室收缩功能的临床应用价值。方法选择30例SLE患者(SLE组)和32例正常人(对照组)分别进行超声心动图检查,分别应用STI和TDI技术测量右心室游离壁基底段、中间段和心尖段三节段的收缩期峰值应变(S)和应变率(Sr)。结果 STI显示SLE组右室游离壁基底段、中间段和心尖段S均小于对照组(P<0.05);TDI显示SLE组右心室游离壁基底段和中间段S均小于对照组(P<0.05),但心尖段S在两组中无显著差异。结论 SLE患者的右心室收缩功能减低,STI和TDI可评价SLE患者右心室收缩功能。Objective To early assess the right ventricular longitudinal systolic function using the systolic longitudinal peak strain （S） with speckle -tracking imaging （STI） and tissue doppler imaging（TDI）, and evaluate its clinical value in patients with systemic lu- pus erythematosus （SLE）. Methods Thirty SLE patients and 32 control subjects underwent the ultrasonic examination. The systolic lon- gitudinal peak strain （S） were obtained on segments of the right ventricular free wall at apical four - chamber view using STI and TDI. All the parameters were compared between the two groups. Results STI displayed The S of the right ventricular free wall on basal,medial and apical segments were decreased in SLE patients（ P 〈 0.05 ）. TDI showed right ventricular free wall of basal and medical strain of SLE group was less than that of the control group （P 〈 0.05） ,but the apical S in the two groups had no significant difference. Conclusion The right ventricular systolic function is weakened in SLE patients. STI and TDI are an early way for assessing the right ventricular systolic function.
