【摘要】：目的:应用超声三维斑点追踪技术评价腹型肥胖患者左室整体心肌应变及形态结构的改变,探讨其临床应用价值。方法:选择40例健康对照者、42例腹型肥胖患者(AO组)、41例代谢综合征患者(MS组),测量各组的腰围(WC)、腰臀比(WHR),采用超声三维斑点追踪技术测量左室球形指数(LV SpI)、左室质量(LV Mass)、左室整体收缩期峰值纵向应变(GLS)、圆周应变(GCS)、径向应变(GRS)及面积应变(GAS),比较3组间上述各参数的差异。结果:与对照组比较,AO组的LV SpI减低、LV Mass增大、GLS减低(P0.01),而GCS、GRS及GAS差异均无统计学意义(P0.05)。与MS组比较,AO组GLS、GCS及GAS的差异均有统计学意义(P0.01)。AO组的GLS与WC、WHR及LV Mass呈显著正相关(r=0.558、0.572、0.443,P0.05)。结论:三维斑点追踪技术可早期检测腹型肥胖患者左室整体收缩功能和形态结构的改变,纵向应变的降低与腹型肥胖的程度及左室重构有关。
[Abstract]:Objective: to evaluate the changes of left ventricular global myocardial strain and morphologic structure in patients with abdominal obesity by using three dimensional ultrasonic speckle tracing technique. Methods: 42 patients with abdominal obesity were selected from 40 healthy controls and 42 patients with abdominal obesity were selected. 41 patients with metabolic syndrome were treated with MS group. The waist circumference (WCN) and waist-hip ratio (WHR) of each group were measured. Three-dimensional ultrasonic speckle tracing technique was used to measure them. The spherical index of left ventricle (LV SpIn), left ventricular mass mass (LVMS), left ventricular global systolic peak longitudinal strain (GLSN), circumferential strain (GCS), radial strain (GRS) and area strain (GASA) were compared between the three groups. Results: compared with the control group, these parameters were compared with those of the control group. There was no significant difference in GRS and GAS between LV SpI and LV Mass. Compared with MS group, there was a significant difference in GLS and GAS between AO group and MS group. There was a significant positive correlation between GLS and WCU WHR and LV Mass in AO group. Conclusion: there is a significant positive correlation between GLS and WCU WHR and LV Mass. Conclusion: there is a significant positive correlation between GLS and WCU WHR and LV Mass in AO group. Conclusion: there is a significant positive correlation between GLS and WCU WHR and LV Mass in AO group compared with MS group. Conclusion: there is a significant positive correlation between GLS and WCU WHR and LV Mass in AO group. Tracer technique can be used to detect the changes of left ventricular global systolic function and morphologic structure in patients with abdominal obesity. The decrease of longitudinal strain is related to the degree of abdominal obesity and left ventricular remodeling.
