Abstract

Objective To study the clinical significance of the change of plasma BNP levels in patients with grades sepsis and its correlation with the left ventricular ejection fraction.Methods One hundred patients of sepsis who were admitted in intensive care unit of Taizhou hospital were selected.It was divided into four groups:30 patients with septic shock,40 patients with severe sepsis,30 patients with sepsis and 20 persons without disease as control group.The concentration of plasma BNP was determined using sandwich immunoflurescence,and ultrasonic cardiogram was used to evaluate heart function and clinical features in all groups.To compare with the differences of the concentration of plasma BNP and the correlation between the concentration of Plasma BNP and LVEF in all groups,the data of clinical features,28-day mortality,prognostic values of BNP and the length of stay (ROG) in ICU were collected and compared.Result Plasma BNP levels in patients with septic shock[ (976.3 ± 160.7) pg/ml] were obvious higher than severe sepsis[ (648.4 ± 267.3) pg/ml ],sepsis [ (217.2 ± 89.7) pg/ml ] and control group [ (50.3 ± 25.4)pg/ml] (P ＜0.01).LVEF in patients with septic shock [ (48.2 ±9.6)% ] was obvious lower than severe sepsis[ (52.8 ±9.4)% ],sepsis[ (61.3 ± 8.9)% ] and control group[ (66.4 ±9.3)% ] (P ＜0.05 or P ＜0.01).It appeared to be inverse relationship between LVEF and the plasma BNP levels (r =-0.876,-0.724,P ＜0.01).BNP levels were significantly higher in non-survivors compared with survivors[ (1367.6±506.4)pg/ml vs (420.3 ±82.6)pg/ml,P ＜0.01 ].The receiver operating characteristic (ROG) curves indicated that values of areas under the curve of plasma BNP levels for 28-days mortality were 0.918(P ＜0.01).Conclusion The concentration of plasma BNP in patients was different in different grades of sepsis.It appeared to be negative correlation between the concentration of plasma BNP and LVEF.Plasma BNP levels had predictive value to the patients with sepsis.
