| 目的 应用超声二维应变成像检测系统性红斑狼疮(SLE)患者颈动脉整体圆周应变(CS)、应变率(CSr)和硬度参数(β),探讨其评价颈动脉弹性的临床应用价值。 方法 选择30例患者(SLE组)和32名正常人(对照组),在颈总动脉二维短轴图像测量收缩期峰值CS和CSr,分别根据M型超声和二维应变成像计算动脉硬度参数(β1和β2),并对两者进行相关性分析。 结果 SLE组颈动脉CS和CSr均小于对照组, β1和β2则明显增大 (P<0.05),且β2和β1显著相关(r=0.61,P<0. 01)。 结论 超声二维应变成像是早期评价SLE患者颈动脉弹性减低的新技术。 |

| Objective To assess clinical value of measuring the carotid artery elasticity using the circumferential strain (CS) and circumferential strain rate (CSr) and stiffness parameter (β) with two-dimensional (2D) strain imaging in patients with systemic lupus erythematosus (SLE). Methods Thirty patients with SLE and 32 control subjects underwent the examination of 2D strain imaging, the systolic global peak CS and CSr of the carotid artery were obtained at artery 2D short-axis imaging, and the stiffness parameters (β1 and β2) were measured with M-mode ultrasonography and 2D strain imaging, respectively. All the parameters were compared between the two groups. Results The CS and CSr decreased, and β1 and β2 increased in patients with SLE (P<0.05). The β2 correlated significantly with β1 (r=0.61, P<0.01). Conclusion Two-dimensional strain imaging is a new technique for early assessing the carotid artery elasticity in patients with SLE. |
