实时三维超声心动图与二尖瓣环运动速度评价扩张型心肌病患者左室整体收缩功能的对比研究
A Comparison Study of Left Ventricular Systolic Function by RT-3DE and Sm in Patients with Dilated Cardiomyopathy
【摘要】 目的比较实时三维超声(RT-3DE)与二尖瓣环运动速度(Sm)评价扩心病(DCM)患者的左室整体收缩功能的临床价值。方法 DCM组33例,对照组28例,行二维(2DE)、组织多普勒(TDI)及RT-3DE扫查,测量并计算各参数:(1)Sm(侧壁)、Sm(室间隔)、Sm(平均),(2)左室射血分数(LVEFSimpson与LVEFRT-3DE)。结果与对照组相比,DCM组LVEFSimpson、LVEFRT-3DE、Sm(侧壁)、Sm(室间隔)、Sm(平均)明显减低(P<0.01)。在对照组中,LVEFRT-3DE、Sm(侧壁)、Sm(室间隔)、Sm(平均)与LVEFSimpson均显著相关(r=0.895,P<0.01;r=0.629,P<0.05;r=0.508,P<0.05;r=0.562,P<0.05)。在DCM组中,LVEFSimpson与LVEFRT-3DE及Sm(侧壁)、Sm(室间隔)、Sm(平均)显著相关(r=0.818,P<0.01;r=0.487,P<0.05;r=0.301,P<0.05;r=0.368,P<0.05)。结论与Sm相比较,LVEFRT-3DE能更准确、有效地评价DCM患者左室整体收缩功能。
【Abstract】 Objective To compare the RT-3DE and Sm in patients with dilated cardiomyopathy(DCM). Methods 33 patients with DCM and 28 normal subjects were enrolled in the study.All correlative parameters,including Sm(lateral wall),Sm(septum),Sm(mean),LVEFSimpson,LVEFPT-3DE,were measured by 2DE,RT-3DE and TDI.Results Compared with controls,LVEFSimpson,LVEFRT-3DE and Sm(lateral wall),Sm(septum),Sm(mean) decreased in the DCM(P<0.01).In the normal subjects,LVEFSimpson was significantly related to LVEFRT-3DE(r=0.895, P<0.01),Sm(lateral wall)(r=0.629,P<0.05),Sm(septum)(r=0.508,P<0.05) and Sm(mean)(r=0.562,P<0.05),and in the DCM group,LVEFSimpson was significant related to LVEFRT-3DE(r=0.818,P<0.01),Sm(lateral wall)(r=0.487,P<0.05),Sm(septum)(r=0.301,P<0.05),Sm(mean)(r=0.368,P<0.05).Conclusions Compared with Sm,LVEFRT-3DE may be a better and helpful parameter for evaluation left ventricular global systolic function in DCM.
