【摘要】：目的采用二维斑点追踪(2D-STE)技术评价系统性红斑狼疮(SLE)患者的右心房功能变化。方法选取A组(对照组)为健康志愿者30例。根据患者肺动脉收缩压(PASP)不同的SLE患者102例分为3组(实验组),B组PASP≤30mm Hg,C组30mm HgPASP50mm Hg,D组PASP≥50mm Hg。采用常规二维超声测量心室收缩期末右心房的最大容积、最小容积及右心房的收缩前容积(RAVmax、RAVmin及RAVpre),计算右心房的被动排空分数及其主动排空分数(RAPEF及RAAEF)。2D-STE技术获取收缩期右心房整体峰值应变率、舒张早期右心房整体峰值应变率及舒张晚期右心房整体峰值应变率(SRs、SRe及SRa)。结果 B组所有测量的结果同A组相比无统计学意义(均P0.05)。C组中RAVmax、RAVmin、RAVpre、RAAEF和SRa与A、B组相应值比较均增大(均P0.05),RAPEF、SRe和SRs均减小(均P0.05)。D组中RAVmax、RAVmin、RAVpre、RAAEF和SRa与A、B、C组比较明显增大(均P0.05),RAPEF、SRe和SRs明显减小(均P0.05)。结论 2D-STE可以评价不同程度PASP的SLE患者的右心房的功能。
