| 目的 了解二维和三维斑点追踪技术用于川崎病患儿左室收缩功能检测和评价的差异,为该技术的临床使用提供理论经验。 方法 2014年1月-2016年12月期间,对我院收治的50例川崎病患儿进行研究,分析使用2D-STE和3D-STE分别检测患儿心脏不同部位(基底部、中间段、心尖部)具体参数(左心室舒张末期容积、收缩末期容积、左心室射血分数、纵向应变、环向应变、径向应变)、冠状动脉扩张与不均匀情况的统计学差异。 结果 患儿分别使用2D-STE和3D-STE进行检测,EDV、ESV、LVEF结果的差异均显示出统计学意义(均有P<0.05)；LVEF结果的差异无统计学意义(P>0.05)；分别使用2D-STE和3D-STE检测患儿心肌各部位的应变,检测基底部时,LS、CS、RS的差异均有统计学意义(均有P<0.05)；检测中间段,LS的差异均有统计学意义(均有P<0.05)；检测心尖部,LS、CS、RS的差异均有统计学意义(均有P<0.05)；使用2D-STE检测患儿,不同部位LS、CS、RS检测结果的差异有统计学意义(均有P<0.05)；使用3D-STE检测患儿,不同部位LS、CS、RS检测结果的差异有统计学意义(均有P<0.05)； 患儿分别使用2D-STE和3D-STE进行心脏探察,两种方法检测左冠脉、右冠脉(扩张和不均匀)时,其检测结果的差异均无统计学意义(均有P>0.05)。 结论 3D-STE相比2D-STE检测方法,其检测应变的结果更为全面和精确,也能更早的反映川崎病患儿左室的收缩功能。 |

| Abstract: |
| To understand the difference between 2d and 3d speckle tracking technology for left ventricular systolic function detection and evaluation in children with kawasaki disease, and to provide theoretical experience for the clinical use of this technique. Methods During January 2014 - December 2016， in 50 cases of children with kawasaki disease in our hospital research， analysis of the use of 2 d - STE and 3 d - STE children heart was detected in different position （base）， middle section， apex of specific parameters （left ventricular end-diastolic volume and left ventricular ejection fraction， end systolic volume， longitudinal strain， ring to strain， radial strain）， coronary artery expansion with the condition of non-uniform statistical differences. Results The children were tested using 2D-STE and 3D-STE respectively， and the differences in EDV， ESV and results showed statistical significance （P< 0.05）. The difference between LVEF results was not statistically significant （P> 0.05）. The differences of LS， CS and RS were statistically significant （P < 0.05）， respectively， when 2D-STE and 3D-STE were used to detect the strain of each part of the heart muscle. In the middle segment， the difference of LS was statistically significant （P < 0.05）. The differences in the detection of the apex of the heart， LS， CS and RS were statistically significant （P < 0.05）. The difference between the test results of LS， CS and RS in different parts was statistically significant （P < 0.05）. The difference between different sites of LS， CS and RS was statistically significant （ P< 0.05）. The children were using 2D-STE and 3D-STE for cardiac exploration， and the two methods were used to detect the left coronary artery， right coronary artery （dilation and inhomogeneity）， and the differences in the test results were not statistically significant （P > 0.05）. Conclusions 3D-STE is more comprehensive and accurate than 2D-STE detection method, and it can reflect the contractile function of left ventricle in children with kawasaki disease earlier. |
