Abstract: OBJECTIVE: To explore the diagnostic value of brain natriuretic peptide (BNP) level in patients with sepsis of blood-stasis syndrome. METHODS: The prospective method of clinical diagnostic test and evaluation principles of diagnostic test were applied. One hundred and seventy-four patients with sepsis were divided into two groups: blood-stasis syndrome group and non blood-stasis syndrome group. The levels of serum BNP in two groups were detected. RESULTS: The level of BNP in sepsis patients was related to blood-stasis syndrome (P<0.01). BNP cut-off level was 150 ng/L, sensitivity was 85.3%, specificity was 81%, the maximum value of Youden index was 0.663, and the area under the receiver operating characteristic curve (ROC) value was (0.886+/-0.025). CONCLUSION: BNP can be used as an objective index of blood-stasis syndrome diagnosis for sepsis, and BNP with boundary value of 150 ng/L is an optimal biological index.
