目的:应用Tei指数与斑点追踪超声心动图(STE)评价心力衰竭(HF)患者左心室和左心房的功能。方法收集射血分数正常的 HF(HFNEF)和射血分数减低的 HF(HFREF)患者各30例,正常志愿者30名作为对照组。采用实时三维超声心动图(RT-3DE)测量左心室舒张末期容积(EDV),左心室收缩末期容积(ESV),左心室射血分数(LVEF);并测量左心房最大容积(LAVmax)、左心房最小容积(LAVmin)、左心房收缩前容积(LAVpre),计算左心房整体射血分数(LAEF)、左心房被动射血分数(LAPEF)、左心房主动射血分数(LAAEF);使用组织多普勒(TDI)测量等容收缩时间(ICT)、等容舒张时间(IRT)、射血时间(ET),计算Tei指数;应用STI技术测量收缩期、舒张早期、舒张晚期左心室和左心房纵向峰值应变及应变率。结果对照组、HFNEF组和HFREF组间EDV、ESV依次递增, LVEF依次递减;心衰组较对照组LAVmax、LAVmin、LAVpre增大,LAEF、LAPEF、LAAEF减低(P<0.05),但HFNEF组与HFREF组间差异无统计学意义。三组间IRT递增,ET递减,Tei指数递增(P<0.05)。三组间左心室及左心房的S及SR依次递减(P<0.05)。与左心室相比,左心房所测S及SR与Tei指数的相关性更好(r值分别为-0.668、-0.626、-0.632、0.520,P均<0.01)。结论 Tei指数及STE可以准确检测及量化心肌功能。

Objective To evaluate left ventricular and left atrial function in patients with heart failure using Tei index and two-dimentional speckle tracking echocardiography(STE). Methods 30 heart failure patients with normal ejection fraction(HFNEF group), 30 heart failure patients with reduced ejection fraction(HFREF group), and 30 healthy controls(control group) were enrolled in this study. The left ventricular ejection fraction (LVEF) and left atrial ejection fraction (LAEF) were measured by real-time three-dimentional echocardiography (RT-3DE);Tei index was calculated based on isovolumic contraction time(ICT), isovolumic relaxation time (IRT) and ejection time (ET);The longitudinal peak strain and strain rate of the left ventricular and atrium in systolic, early diastolic, late diastolic phase were recorded. Results EDV, ESV showed a tendency to increase and LVEF to decrease among the control group, HFNER group and HFREF group. Compared with control group, LAVmax, LAVmin, LAVpre increased and LAEF, LAPEF, LAAEF decreased (P<0.05) in HFNEF and HFREF group, but no significant difference was found between HFNEF and HFREF group. IRT extend, ET shorten, Tei index increase progressively among such three groups (P<0.05). Both S and SR in left ventricular and atrium showed a tendency to decrease in HFNEF and HFREF group(P<0.05);S and SR of left atrium correlated better with Tei index than that of left ventricular(r=-0.668,-0.626,-0.632,0.520, P<0.01). Conclusion Tei index and STE allowed accurate detection and quantification of myocardial function.
