摘　　要：目的探讨实时三维超声心动图(RT-3DE)联合Tei指数评价心力衰竭患者左室心功能的效果。方法应用RT-3DE和脉冲多普勒超声分别测量104例心力衰竭患者和74例正常人(对照组)的左室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、射血分数(LVEF)、左室心肌质量(LVM)、射血时间(ET)和Tei指数。结果心力衰竭患者的LVEDV、LVESV、LVM、左室心肌质量指数(LVMI)和Tei指数均明显大于对照组(P<0.05),LVEF和ET明显小于对照组(P<0.05)。心力衰竭患者LVEF与LVM呈负相关关系(P<0.05),Tei指数与LVM呈正相关关系(P<0.05);Tei指数与LVEF呈负相关关系(P<0.05)。结论 RT-3DE联合Tei指数能更好地准确评价心力衰竭患者的左室功能,有效判断心力衰竭的严重程度,并提供分型依据。Objective To evaluate left ventricular function （LVF） in patients with heart failure （HF） evaluated by using real-time three-dimensional echocardiography （ RT-3DE） in combination with Tei index .Methods RT-3DE and pulsed doppler ultrasound were used to measure left ventricular end diastolic volume （ LVEDV） ,left ventricular end systolic volume（LVESV）,left ventricular ejection fraction （LVEF）,left ventricular mass（LVM）,ejection time（ET） and Tei index in 104 patients with HF and 74 healthy volunteers （ control group）.Results LVEDV,LVESV,LVM,left ventricular mass index （ LVMI） and Tei index were significantly higher but LVEF and ET were significantly lower in patients with HF in contrast with those in the control group （ P〈0 .05 ） .LVEF negatively correlated with LVM while Tei index positively correlated with LVM in patients with HF （ P〈0 .05 ） , and Tei index negatively correlated with LVEF（P〈0.05）.Conclusion RT-3DE combined with Tei index can accurately evaluate LVF in patients with HF better , judge the severity of HF effectively , and provide the evidences for HF typing .
