目的:探究超声速度向量成像(VVI)评估甲状腺功能亢进(简称甲亢)性心脏病心肌节段运动异常的价值.方法:选取2019年8月至2021年8月在秦皇岛市第一医院就诊的76例甲亢性心脏病患者,根据患者升主动脉受损程度将其中30例升主动脉内径＞30 mm的患者纳入内径＞30 mm组,将46例升主动脉内径＜30 mm的患者纳入内径＜30 mm组,另选同期进行健康体检的40名体检者纳入健康对照组.所有受检者均行常规超声心动图检查,将图像导入VVI工作站,选择清晰、标准的二维灰度动态图像进行分析.对左心室进行跟踪分析,存储并记录3个心动周期的左心室长轴、心尖四腔、两腔心18个节段心肌纵向运动的达峰值速度、50%峰值速度和75%峰值速度的时间,以及短轴二尖瓣水平、乳头肌水平切面12个节段心肌径向运动的达峰值速度、50%峰值速度和75%峰值速度的时间.结果:三组受检者左心室侧壁基底段、中间段,前壁基底段,下壁基底段、中间段和心尖段,后壁基底段、中间段和心尖段纵向收缩达峰值时间比较,差异有统计学意义(F=45.02、23.19、8.70、19.82、16.17、18.07、36.85、48.65、36.64,P＜0.05).三组左心室下壁短轴二尖瓣、乳头肌水平径向收缩达峰值速度时间比较,差异有统计学意义(F=15.44、40.35,P＜0.001).结论:VVI技术能够准确地检测出甲亢性心脏病患者左心室短轴和长轴心肌收缩运动同步性的细微变化,在评估甲亢性心脏病心肌节段运动异常中具有较高的应用价值.
Objective:To explore the value of ultrasonic velocity vector imaging(VVI)in assessing motion abnormality of myocardial segment of hyperthyroid heart disease.Methods:A total of 76 patients with hyperthyroid heart disease who admitted to hospital from August 2019 to August 2021 were selected.According to the damage degree of ascending aorta of patients,30 patients whose inner diameter of ascending aorta was greater than 30 mm were included in the"inner diameter>30mm"group,and 46 patients whose inner diameter of ascending aorta was less than 30 mm were included in the"inner diameter<30mm"group.Additionally,40 healthy individuals who underwent physical examinations during the same period were selected as the healthy control group.All subjects underwent routine echocardiography examination,and the images were imported into the velocity vector imaging(VVI)workstation.And then,the clear and standard two-dimensional grayscale dynamic images were selected to conduct analysis.The left ventricle was tracked and analyzed,and the left ventricular long axis,the apical four chamber,and the velocity of reaching peak value,the time of 50%velocity and the time of 75%velocity of longitudinal myocardial movement of 18 segments of two chambers,as well as the mitral valve level of short axis,the velocity of reaching peak value of reaching peak value,the time of 50%velocity and the time of 75%velocity of radial myocardial movement of 12 segments of horizontal section of papillary muscle,of three cardiac cycles were stored and recorded.Results:There were significant differences in the time to peak of longitudinal contraction at the basal segment and middle segment of left ventricular lateral wall,and the basal segment of front wall,the basal segment,middle segment and apical segment of inferior wall,as well as the basal segment,middle segment and apical segment of posterior wall among three groups(F=45.02,23.19,8.70,19.82,16.17,18.07,36.85,48.65,36.64,P<0.05),respectively.There were significant differences in the velocity and time of reaching peak value of the radial contraction of the levels of papillary muscle and mitral valve of short axis of left ventricular inferior wall among the three groups(F=15.44,40.35,P<0.001),respectively.Conclusion:VVI technique can accurately detect the subtle changes of the synchronization of myocardial systolic motion of left ventricular short axis and long axis of patients with hyperthyroid heart disease,which has higher application value in assessing the abnormalities of myocardial segmental motion of patients with hyperthyroid heart disease.
