目的 应用二维斑点追踪显像技术(2D-STI)评价扩张型心肌病(DCM)患者左室扭转运动变化对左室重构与功能的影响.方法 DCM患者39例,对照组35例,均接受常规超声心动图、组织多普勒成像检查,获取各受试者左室心底及心尖水平短轴切面观二维图像存盘供Q-lab软件脱机分析.测量参数包括:左室舒张末内径(LVEDd)、左室射血分数(LVEF);左室球化指数(LVSI)、左室重量指数(LVMI);二尖瓣口舒张早期血流速度E、二尖瓣环收缩期运动速度S、舒张早期运动速度E',计算E/ E'; 心底水平和心尖水平左室整体旋转峰值(R心底、R心尖)、左室整体扭转峰值(T)、左室相对扭转(T').结果 与对照组比较,DCM组患者LVEDd、LVMI均显著增大;LVEF及LVSI显著降低; S及E'均显著降低,E/ E'显著增大.根据左室心尖水平旋转方向将DCM患者分为DCM-1组(心尖顺时针旋转)与DCM-2组(心尖逆时针旋转),与对照组比较,两组DCM组患者R心尖、R心底、T、T'均显著减低;与DCM-1组比较,DCM-2组R心底、R心尖、T、T'显著减低,LVEDd、LVMI均显著增大,LVEF及LVSI显著降低,E'显著降低,E/ E'显著增大.结论 DCM患者左室扭转运动减低;心尖水平扭转减低更为显著甚至反向扭转的DCM患者左室重构与功能减低更严重.

Objective To evaluate the effect of torsion on remodeling and function of left ventricle by two-dimensional speckle tracking imaging(2D-STI) in patients with dilated cardiomyopathy(DCM).MethodsThirty-nine patients with DCM and thirty-five controls accepted conventional echocardiography,pulsed-wave Doppler tissue imaging examination.Basal and apical short-axis view of left ventricle were accorded for Q-lab analysis.Indices included:left ventricular diameter in end diastole (LVEDd),left ventricular ejection fraction (LVEF),left ventricular sphericity index (LVSI),left ventricular mass index (LVMI),e-wave of mitral valvular flow (E),velocity of mitral annulus in systole (S),velocity of mitral annulus in early distole ( E'), E/ E',rotation of left ventricle at basal and apical level(Rbasal,Rapical),twist (T),torsion (T').Results Compared with controls,LVEDd,LVMI of patients with DCM increased significantly,LVEF and LVSI decreased significantly,S and E' decreased significantly,E/ E' increased significantly.Patients with DCM were divided into two groups:group DCM-1 (clockwise rotation at apical level) and group DCM-2 (countclockwise rotation at apical level).Compared with controls,Rasal,Rapical,T,T' of two DCM groups decreased significantly.Compared with group DCM-1,Rbasal,Rapical,T,T' of group DCM-2 decreased significantly,LVEDd,LVMI increased significantly,LVEF and LVSI decreased significantly,E' decreased significantly,E/ E' increased significantly.Conclusions The torsion of left ventricle decrease in patients with DCM,DCM patients with decreased or reversed torsion of left ventricular apex have more severe LV remodeling or damage of LV function.
