| 目的 评价系统性红斑狼疮(SLE)患者左、右心室纵向收缩功能。方法 对49例SLE患者(SLE组)与33名健康对照者(对照组)均行超声心动图检查,并应用二维斑点追踪及组织多普勒技术获取三尖瓣瓣环位移(TAPSE)、三尖瓣瓣环等容收缩期速度(IVCv)和三尖瓣瓣环收缩期速度(PSv)。应用QLab 9.0软件分析获得左心室整体纵向应变值(GLS)。结果 SLE组GLS值、TAPSE、IVCv及PSv均低于对照组,差异均有统计学意义(P均<0.01)。SLE组中抗心肌抗体(AMA)阴性者TAPSE和PSv低于对照组(P均<0.05)。GLS与左心室射血分数(LVEF)、TAPSE、IVCv及PSv有一定的相关性(r=-0.57、-0.76、-0.81、-0.78,P均<0.01)。结论 SLE患者左、右心室纵向收缩功能有不同程度的受损。 |

| Objective To explore the cardiac longitudinal systolic function in patients with systemic lupus erythematosus (SLE). Methods Forty-nine patients with SLE (SLE group) and thirty-three healthy controls (control group) were collected and underwent transthoracic echocardiography, as well as two-dimensional speckle tracking imaging and tissue Doppler imaging, and then the tricuspid annular plane systolic excursion (TAPSE), isovolumic contraction peak velocity at the tricuspid annulus (IVCv), peak systolic velocity (PSv) were measured. Global longitudinal strain (GLS) was calculated via QLab 9.0 analysis software offline. Results Compared with control group, the GLS, TAPSE, IVCv and PSv reduced in SLE group (all P<0.01). The TAPSE and PSv in patients with negative antimyocardial antibody (AMA) were lower than those in control group (all P<0.05). The left ventricular ejection fraction (LVEF), TAPSE, IVCv and PSv were correlated with GLS (r=-0.57, -0.76, -0.81, -0.78, all P<0.01). Conclusion The longitudinal systolic function of left and right ventricle are impaired in patients with SLE. |
