Abstract: Objective To explor the value of Tei index for evaluation the cardiac function of patients with chronic heart failure(CHF).Methods Tei index in 60 patients with CHF(CHF group) and 30 normal controls(control group) were evaluated and compared with the levels of NT-ProBNP and the NYHA class,and the sensitivity and specificity of Tei index for CHF diagnosis were appraised.Results (1) Tei index in CHF group was significantly higher than that in control group.When Tei index was more than and equal to 0.45,the sensitivity,specificity,positive predictive value,and negative predictive value of Tei index for diagnosing CHF were 85.6％,90.4％,89.8％ and 78.0％.(2)There was a remarkable positive correlation between Tei and Log NT-ProBNP(r =0.84,P ＜ 0.01).(3)There were significant differences in Tei index among NYHA Ⅱ,Ⅲ,Ⅳ class [(0.47 ± 0.06),(0.56 ± 0.08),(0.64 ±0.13)].Conclusion Tei index can be used to diagnose CHF and evaluate the degree of it.
