【摘要】：目的探讨超声二维斑点追踪显像技术(STI)在2型糖尿病(T2DM)患者左心室心肌扭转运动中的运用价值。方法选择该院2014年1月至2015年1月收治的T2DM患者50例,根据组织多普勒成像技术(TDI)检查结果,二尖瓣环舒张早期峰值运动速度(Em)/舒张晚期峰值运动速度(Am)1患者为左室舒张功能正常组(TN组)19例,Em/Am≤1患者为左室舒张功能异常组(TA组)31例,另纳入同期来该院体检的健康成人24例为对照组。所有研究对象入院后接受彩色多普勒超声检查,并应用超声二维STI软件分析扭转角度峰值(PTw)、扭转角度达峰时间(TPTV)、解旋速度峰值(PUV)和解旋率(Untw R)。结果 TN组和TA组PTw、PUV均显著高于对照组(均P0.05),TN组和TA组Un Tw R均显著低于对照组(均P0.05),且TA组显著低于TN组(P0.05),三组TPTV比较无统计学意义(P0.05)。结论超声二维STI技术对于评价T2DM患者左室心肌功能具有更高的敏感性,能够较早发现患者左室扭转异常。
[Abstract]:Objective to evaluate the value of STI in left ventricular torsion in patients with type 2 diabetes mellitus (T2DM). Methods 50 patients with T2DM were selected from January 2014 to January 2015. According to the results of tissue Doppler imaging (TDI), The mitral annular early diastolic peak motion velocity and the late diastolic peak motion velocity were 31 cases in the left ventricular diastolic function normal group (n = 19), the left ventricular diastolic function group (n = 19) and the left ventricular diastolic dysfunction group (n = 31), the left ventricular diastolic dysfunction group (n = 31) and the left ventricular diastolic dysfunction group (n = 31). Another 24 healthy adults who were examined in the same period were taken as the control group. All the subjects were examined by color Doppler ultrasound after admission. The STI software was used to analyze the peak value of torsion angle, the peak time of torsion angle, the peak time of torsion angle and the peak value of unspin velocity. Results both TN group and TA group were significantly higher than those in control group (P 0.05%) and TA group (both P 0.05% and TA group) were significantly higher than those in control group (P 0.05%) and TA group (U n Tw R) was significantly higher than that in control group (P < 0.05). It was significantly lower in TA group than in TN group (P 0.05). There was no significant difference in TPTV between the three groups (P 0.05). Conclusion Ultrasound two-dimensional STI is more sensitive in evaluating left ventricular myocardial function in patients with T2DM. Abnormal left ventricular torsion can be detected earlier.
