摘　　要：目的 三维斑点追踪技术（3D-STE）评价缺铁性贫血（IDA）患者的左心室（LV）心肌收缩功能。方法 65例IDA患者按照血红蛋白（Hb）的浓度分为两组：B组Hb〉90g/L,C组Hb 60-90g/L。同时收集30例健康人作为对照组A组。对3组进行常规超声心动图检查,三维超声测量舒张末期左室容积（LVEDV）、收缩末期左室容积（LVESV）、左室射血分数（LVEF）,并计算左室质量指数（LVMI）,3D-STE分析左心室整体纵向应变（GLS）、整体面积应变（GAS）、整体径向应变（GRS）和整体周向应变（GCS）。结果 C组与B、A组间比较,LVEDV、LVESV和LVMI均升高,差异具有统计学意义（P均〈0.05）;GRS、GCS、GLS和GAS均减低,差异有统计学意义（P均〈0.05）。结论 3D-STE能够有效地评估缺铁性贫血患者左心室心肌收缩功能的改变。Objective The aim of this study was to assess the impact of left ventricular （LV） systolic function in patients with iron deficiency anemia （IDA） by 3D speckle tracking echocardiography （3D-STE）. Methods Sixty-five patients who were diagnosed as IDA were divided into 2 groups with hemoglobin levels. Group B： （Hb〉90 g/L）, Group C： （Hb 60--90 g/L）. We also enrolled 30 healthy control subjects as Group A. The parameters of the conven- tional echocardiography and 3D-STE were obtained respectively. Left ventricular end-diastolic volume（LVEDV）, left ventricular end-systolic volume（LVESV）, left ventricular ejection fraction （LVEF）, left ventricular mass index（LV- MI）were measured and calculated by 3D technology. We used 3D-STE to analyze left ventricle global longitudinal strain （GLS）, global area strain （GAS）, global radial strain （GRS） and global circumferential strain （GCS）. Results The LVMI, LVEDV and LVESV of group C were increased significantly compared with those of groups A and B（all P〈0.05）. Compared with groups A and B, GCS, GRS, GLS and GAS of group C were significantly decreased （all P 〈0.05）. Conclusions 3D-STE can effectively assess LV systolic function in patients with IDA.
