| 摘 要： | 目的 应用超声二维斑点追踪显像(STI)技术评价孤立性心肌致密化不全(IVNC)患者左心室局部心肌收缩功能。 方法 对34例IVNC患者(IVNC组)及28名健康志愿者(对照组)进行超声检查,分析左心室二尖瓣、乳头肌、心尖水平短轴切面及心尖左心室长轴、四腔、两腔切面连续3个心动周期的二维灰阶图像。按照18节段划分法,记录左心室各节段心肌径向(Sr)、圆周(Sc)、纵向(εS)收缩期峰值应变,并将受累节段与未受累节段及对照组同水平相应节段进行比较。 结果 ①与对照组比较,IVNC组左心室所有节段心肌Sr、Sc、εS均减低(P<0.05)。②IVNC组非致密心肌(乳头肌及心尖水平)Sr、Sc、εS测值较同一水平致密心肌减低(P<0.05)。③与对照组比较,IVNC组心率、LADs、LVEDD、LVM、LVMI、EDV、ESV值均增加,IVSd、LVPWDd、LVEF值均减小(P<0.01)。 结论 IVNC患者左心室局部心肌收缩功能减低,以受累节段收缩功能减低尤为明显。STI技术可准确定量分析IVNC患者左心室局部心肌收缩功能。

| Abstract: | Objective To evaluate the systolic function of noncompacted and compacted left ventricular segments in patients with isolated ventricular non-compaction(IVNC) using speckle tracking imaging(STI).Methods Thirty four patients with IVNC(IVNC group) and 28 healthy subjects(control group) were enrolled in the study.High frame rate two-dimensional images of three consecutive cardiac cycles at the levels of mitral annulus,papillary muscle and the apex as well as apical long axis view of left ventricle,apical 4 cha... |
