目的:探究超声斑点追踪显像技术(STI)在评价左心室心肌致密化不全(LVNC)患者心肌功能中的临床应用价值。方法:选取于2014年6月至2015年6月到该院参与治疗的LVNC患者20例,其中包括LVEF 50%的患者10例与LVEF<50%的患者10例,基于此,将LVEF≥50%的10例患者设置为LVNC-1组,将LVEF<50%的10例设置为LVNC-2组,将年龄、性别与此相对应的20例健康志愿者设置为对照组。对比分析对照组与LVNC-1组、LVNC-2组的常规超声心动图测量值、不同水平下的收缩期峰值LS。结果:针对常规超声心动图测量值,LVNC-1组、LVNC-2组与对照组在年龄、室间隔厚度上差异并不显著(P>0.05)。LVNC-1组、LVNC-2组与对照组在LVEDD、LVESD以及LVEF差异显著(P<0.05)。针对不同水平下的收缩期峰值LS,LVNC-1组、LVNC-2组LS较于对照组明显减低(P<0.05)。结论:通过超声斑点追踪显像技术,定量评价左心室心肌致密化不全患者心肌功能,效果十分显著,为诊治左心室心肌致密化不全患者提供保障,值得广泛推广。
Objective: To investigate the clinical value of STI in evaluating myocardial function in patients with left ventricular hypertrophy (LVNC). METHODS: Twenty patients with LVNC who were enrolled in this hospital from June 2014 to June 2015 were selected. Among them, 10 patients with LVEF of 50% and 10 patients with LVEF of <50%, based on which LVEF≥50 10% of the patients were set as LVNC-1 group, 10 cases of LVEF <50% were set as LVNC-2 group, and 20 healthy volunteers with corresponding age and sex were set as control group. Contrast analysis of routine echocardiographic measurements between the control group and the LVNC-1 group, LVNC-2 group, systolic peak LS under different levels. Results: There was no significant difference in age and ventricular septal thickness between LVNC-1 group and LVNC-2 group and control group (P> 0.05). LVNC-1 group, LVNC-2 group and control group had significant differences in LVEDD, LVESD and LVEF (P <0.05). The LS of LVNC-1 group and LVNC-2 group were significantly lower than that of the control group (P <0.05) at different levels of systolic peak. CONCLUSION: Quantitative evaluation of myocardial function in patients with left ventricular hypertrophy through ultrasound speckle tracking imaging is very effective. It is worth to be widely used in the diagnosis and treatment of patients with left ventricular hypertrophy.
