目的:探讨组织多普勒技术对2型糖尿病(type 2 Diabetes mellitus ,T2DM)患者心脏右心室功能的诊断价值,分析T2DM患者右室功能变化。方法 选取单纯2型糖尿病患者30例(糖尿病组),常规超声心动图检查后;M型测量右心室侧壁三尖瓣环收缩期位移(tricuspid annulus systolic offset,TAPSE);脉冲多普勒成像(Pulse Doppler imaging,PDI)检测三尖瓣口舒张期血流速度(VE、VA),并计算E/A;Simpson法测量右室收缩功能EF值(RVEF);应用组织多普勒技术分析糖尿病患者右心室侧壁三尖瓣环处等容收缩期速度(isovolumic contraction velocity,IVCv),收缩期速度(systolic velocity,Vs) 以及IVCv/Vs;舒张期速度Ve、Va,并计算Ve/Va。另各取30名同龄健康志愿者作为正常对照组(normal control group,NC)。同样检查超声心动图,测量以上各数值。对以上结果进行比较分析。结果: T2DM组与NC组的RVEF、三尖瓣环位移(TAPSE)均在正常范围,两组差异无统计学意义(P>0.05)。糖尿病组右心室收缩速度Vs较对照组减低,等容收缩期速度(IVCv)较对照组偏高。IVCv / Vs 与对照组相比明显偏高。T2DM组舒张期Ve/Va低于对照组(P<0.05)。结论:T2DM患者存在右室舒张、收缩功能异常,TDI技术可为评价右室功能提供更为敏感的定量指标,同时IVCv / Vs可作为一个衡量右室代偿功能的指标为临床预防和治疗提供依据。 |

Abstract: |
[ ] Objective To evaluate right ventricular function in patients with Type2 diabetes mellitus(T2DM) by Tissue-Doppler Imaging(TDI) , and to determine its clinical value. Methods 30 patients with type 2 DM and 30 health people (control group) were enrolled respectively. After conventional examination by two dimensional echocardiography (2DE), right ventricular function imaging was acquired by TDI. Right ventricular diastolic and systolic pulse frequency were recorded And measured. Results TDI isovolumic contraction velocity in type 2DM and IVCv / Vs were significantly higher than those in control group. systolic velocity VS Ve/Va in type 2DM were significantly lower than those in control group. there was significant difference between two group (P<0.05). Conclusion Tissue-Doppler Imaging could be used accurately, noninvasively to determine right ventricular function of T2DM patients. RV function in patients with 2DM decreases compared NC. |
