Study on correlation between Tei index and left ventricular systolic function in patients with heart failure disease

Objective To explore the correlation of Tei index with left ventricular systolic function(LVSF)in patients with heart failure.Methods We measured left ventricular Tei index in 102 patients with left heart failure using Pulsed Doppler Echocardiography,measured left ventricular end diastolic volume(LVEDV),end systolic volume(LVESV)and ejection fraction(LVEF)in 102 patients with left heart failure using real-time three-dimensional echocardiography,and analyzed the correlation of Tei index with LVEDV,LVESV and LVEF in patients with heart failure.Results Linear correlative analysis showed that the increase of Tei index was positively correlated with the increase of LVEDV and LVESV in patients with left heart failure(r=0.634,P =0.000;r=0.788,P =0.000).Tei index was negative correlation with LVEF(r=-0.758,P =0.000).Conclusion Tei index is closely related to LVSF in patients with left heart failure,and can accurately reflect the left ventricular integral function combined with LVSF.
