There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A＜2 group and E/A＞2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.

扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy，DCM)组患者19例(男性17例，女性2例，年龄18～82岁，平均50.52±17.52岁)，健康体检者21例(男性16例，女性5例，年龄18～80岁，平均49.05±16.94岁)作为对照组，扩心病患者按照E/A分为E/A＜2、E/A＞2两个亚组，结果显示：常规超声显示DCM组LVDd值增大，EF值减小；DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱；与正常组比较，DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s，较正常人显著减低P＜0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P＜0.01，左室舒张末及收缩末时间在DCM-E/A＞2组较正常人及DCM-E/A＜2组显著缩短P＜0.01DCM患者左室解旋速度较正常人亦显著减低(P＜0.01，左室功能轻中度减低(DCM-E/A＜2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低，但当左室功能重度减低(DCM-E/A＞2)时左室解旋率[(0.63±0.35)%]较正常人反而增加；左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。
