Abstract：Objective To evaluate the diagnostic value of left ventricular ejection fraction (LVEF)in heart failure.Methods N termi-nal pro brain natriuretic peptide (NT proBNP)was measured by 411 type electrochemistry luminescence instrument for gold standard and LVEF was measured by B ULTRASONIC with m type for diagnostic test indexs with blind method in 134 cases of pa-tients with heart failure.Then the value of their sensibility,specificity,predicted and likelihood ratio were counted respectively.Results The value of sensibility and specificity were 74.04% and 73.33%,respectively.The positive predicted value and nagtive predicted value were 90.59% and 44.90%,respectively.The value of positive likelihood ratio and nagtive likelihood ratio were 2.78 and 0.35 re-spectively in the diagnostic test.Conclusion LVEF had certain assist diagnostic value in clinical practice,but there were some misdi-agnosis (27%)and missing diagnosis(26%).LVEF could not diagnosed heart failure by alone.That clinical symptoms combined with NYNA cardiac function grading were necesary on diagnosis of heart failure.
