摘　　要：目的探讨二维斑点追踪成像技术(Two-dimensional speckle tracking imaging,2D-STI)检测心肌肥厚患者左心室短轴收缩功能变化的效果。方法选择2016年1月—2018年6月我院接诊的心肌肥厚100例为观察组,选取同期在我院行健康体检的健康者100例,均接受2D-STI检查,比较两组左心室短轴收缩期圆周应变与最大径向应变参数。结果观察组前侧壁、前壁、下壁、后侧壁、前间隔、后间隔左心室短轴收缩期最大圆周应变均低于对照组,差异有统计学意义(P<0.05);观察组前侧壁、前壁、下壁、后侧壁、前间隔、后间隔左心室短轴收缩期最大径向应变均低于对照组,差异有统计学意义(P<0.05)。结论 2D-STI可测量心机肥厚患者左心室短轴收缩功能,准确评价其心室局部运动,值得临床推广。Objective To investigate the effect of two-dimensional speckle tracking imaging(2D-STI)on the changes of left ventricular short-axis systolic function in patients with cardiac hypertrophy.Methods 100 cases of cardiac hypertrophy received from our hospital from January 2016 to June 2018 were selected as observation group.100 healthy subjects who underwent physical examination in our hospital during the same period were examined by 2D-STI.The left ventricle was compared between the two groups.Short-axis systolic circumferential strain and maximum radial strain parameters were compared.Results The maximum circumferential strain of the anterior wall of the anterior wall,anterior wall,inferior wall,posterior wall,anterior septum and posterior septum of the left ventricle was lower than that of the control group,and the difference was statistically significant(P<0.05).The maximum radial strain of the anterior wall,anterior wall,inferior wall,posterior wall,anterior septum and posterior septal left ventricle was lower than the control group,and the difference was statistically significant(P<0.05).Conclusion 2D-STI can measure the left ventricular short-axis systolic function in patients with cardiac hypertrophy and accurately evaluate the local ventricular motion,which is worthy of clinical promotion.
