【摘要】：目的分析相对室壁厚度(RWT)与三维斑点追踪技术(3D-STE)对力量型运动员左室收缩功能的相关性及定量关系。方法收集45例青年男性力量型运动员和30例对照组的常规超声心动图及左室全容积图像,使用3D-STE得到两组参与者的RWT、左室整体纵向应变(GLS)、整体圆周应变(GCS)、整体面积应变(GAS)及整体径向应变(GRS)等数据。分析RWT分别与GLS、GCS、GAS及GRS的相关性,并计算出相应的简单回归方程。结果 RWT与GLS、GCS、GAS及GRS的相关系数r分别为0.400、0.244、0.362、-0.373,得到的RWT(X)与GLS(Y1/%)、GCS(Y2/%)、GAS(Y3/%)及GRS(Y4/%)的简单回归方程分别为Y1=-23.831+22.573X、Y2=-20.346+13.810X、Y3=-38.479+30.469X、Y4=64.345-61.412X,均有统计学意义(P0.05)。结论 RWT与GLS、GCS、GAS及GRS的相关性良好。RWT每增加0.1,GLS、GCS、GAS的绝对值分别降低2.257%、1.381%、3.047%,GRS降低6.141%。RWT可初步评价青年男性力量型运动员左室收缩功能的变化。
[Abstract]:Objective to analyze the correlation and quantitative relationship between relative wall thickness (RWT) and three dimensional speckle tracing (3D-STE) on left ventricular systolic function. Methods conventional echocardiography and left ventricular full volume images of 45 young male athletes and 30 controls were collected. The RWT, global longitudinal strain (GLS), global circumferential strain (GCS), of the two groups of participants were obtained by using 3D-STE. The whole area strain (GAS) and the whole radial strain (GRS) and so on. The correlation between RWT and GLS,GCS,GAS and GRS is analyzed, and the corresponding simple regression equation is calculated. Results the correlation coefficients between RWT and GLS,GCS,GAS and GRS were 0.400, 0.244, 0.362 and 0.373, respectively. The RWT (X) and GLS (Y1 /%), GCS (Y2 /%) were obtained. The simple regression equations of GAS (Y3 /%) and GRS (Y4 /%) were Y _ (1) -23.831 22.573X ~ (2 +) -20.346 13.810X ~ (3) X ~ (38.479) ~ (38.479) ~ (30) 469X ~ (34.345-61.412X), respectively (P0.05). Conclusion there is a good correlation between RWT and GLS,GCS,GAS and GRS. The absolute value of GCS gas decreases by 2.257% and 1.381% and 3.047% for each increase of RWT, respectively. The decrease of 6.141%.RWT by GRS can be used to evaluate the changes of left ventricular systolic function in young male power type athletes.
