Abstract: Objective To investigate the application of combined detection of the N-terminal pro-B-type natriuretic peptide(NT-proBNP)and cardiac troponin I(cTnI)in the diagnosis and treatment of acute heart failure(HF)patients in emergency department.   Methods Enzyme-linked immunosorbent fluorescence assay was used to determine plasma NT-proBNP and cTnI levels in 708 patients with cardiovascular diseases(195 patients with HF and 513 patients with non-HF). Acoording to the New York Heart Assoeiation(NYHA)cardiac function grades,the HF patients were chassified into Grade Ⅰ-Ⅳ. The results were expressed by medians(quartiles). The results were analyzed statistically. Results The levels of NT-proBNP and cTnI in HF group were 3 718(1 035-12 258)ng/L and 7.18(2.05-14.16)μg/L,respectively,which were significantly higher than those in [145(30-585)ng/L for NT-proBNP and 0.66(0.06-1.99)μg/L for cTnI,P<0.01]. Statistical significance was also observed when comparing NT-proBNP and cTnI levels of the patients with HF at NYHA Grade Ⅱ,Ⅲ and Ⅳ (P<0.05). Furthermore,the sensitivity(99%)and specificity(90%)for the diagnosis of HF with the combined detection of NT-proBNP and cTnI were much higher than those with either the detection of NT-proBNP or cTnI alone(P<0.05). Conclusions The combined detection of NT-proBNP and cTnI has valuable significance in the diagnosis and treatment of HF in emergency department.
