值。方法 选择50 例甲状腺功能亢进患者与45 例健康志愿者，获取心尖四腔心切面动态图像，存储左心室三维全容积动态图像后，运用3D-STI 软件进行脱机分析，得到两组收缩期左心室整体纵向峰值应变（GLS）、圆周峰值应变（GCS）、左心室扭转度角度峰值(LV-tw)、左心室扭力（LV-tor）、左心室心底水平旋转角度峰值（Prot-B）、左心室心尖水平旋转角度峰值（Prot-A）及左心室射血分数（LVEF）等，比较两组三维应变（3DS）指标之间的差异。结果 与正常对照组比较，甲亢组的左心室收缩功能增强，GLS、GCS 分别为（-20.47±3.08）% vs.（-18.52±4.77）%、（-28.98±3.00）% vs.（-25.88±2.12）%，两组差异均有统计学意义（均P＜0.05）；甲亢组LV-tw、LV-tor、LVProt-A、LVProt-B 均较正常对照组略有增加，但差异均无统计学意义（均P＞0.05）。结论 3D-STI 可无
创、敏感检测甲亢患者左心室三维应变，为临床客观评估甲亢左心室收缩功能提供一种新方法。 |

| Abstract: |
| Objective To assess left ventricular global systolic function in patients with hyperthyroidism by three-dimensional speckle tracking imaging(3D-STI) echocardiography. Methods Fifty patients with hyperthyroidismand 45 healthy volunteers(control) were studied. The dynamic image of the four-chamber view, three-dimensional imagines of left ventricular were obtained for all individuals, and TomTec 4D LV analysis software was used to calculate the three- dimensional strain (3DS). The 3DS were measured in all subjects and compared between two groups. Results The LVGLS and LVGCS values in hyperthyroidism group were significantly higher than those in control group[(-20.47±3.08)% vs. (-18.52±4.77)% and (-28.98±3.00)%vs. (-25.88±2.12)%, both P＜0.05]; while there were no significant differences in LV-tw, LV-tor, LVProt-A and LVProt-B between two groups. Conclusion Three-dimensional speckle tracking echocardiography can assess alteration of myocardial global systolic function by measuring 3D-strain in patients with hyperthyroidism. |
