目的应用超声斑点追踪技术(speckle-tracking imaging,STI)研究川崎病急性期患者左室收缩功能.方法记录27例川崎病急性期患者(8例冠状动脉扩张)与19例正常儿童的左室心尖位长轴观、二腔观及四腔观,左室二尖瓣环水平、乳头肌水平、心尖水平短轴观的二维灰阶图像,分别测量左室收缩期峰值纵向应变(longitudinal strain,SI)、径向应变(radial strain,SR)与圆周应变(circumferentialstrain,SC).结果 ①川崎病急性期患儿左室大部分节段收缩期峰值SL与SR均低于正常组(P<0.05),且以SI,减低为主;②川崎病急性期患儿左室收缩期峰值SC与正常儿童的差异无统计学意义(P>0.05).③川崎病急性期患儿中8例冠状动脉扩张者(含7支冠状动脉瘤样扩张)左室收缩期峰值SL、SR均低于19例冠状动脉未扩张者,但大部分节段差异无统计学意义(P>0.05).结论急性期川崎病患儿无论有无冠状动脉扩张左室长轴和短轴收缩功能均降低.

Objective To access the left ventricular sysytolic function in children at acute stage of Kawasaki disease using speckle-tracing imaging. Methods Two-dimensional echocardiograghic images of 27 patients and 19 normals were collected in apical long-axis view, two-champer view, four-champer view, short-axis views at the levels of mitral annulus, papillary muscle and apex. The systolic peak values of longitudinal strain, radial strain and circumferential strain were measured by speckle-tracking imaging. Results Compared with controls the values of longitudinal strain and radial strain are lower in most segments in patients(P < 0.05). There were no significant differences between the patients and controls in circumferential strain(P>0.05). Longitudinal strain and radial strain measured were lower in 8 patients with coronary ectasia(including 7 cass with coronary artery aneurysms in vessels) than other 19 patients,but the two groups have no significant differences(P>0.05). Conclusions Long-axis and short-axis function of the heart decreased regardless of coronary artery ectasia.
