ABSTRACT
Objective To investigate the correlation of the S100B level with cardiac function and chronic heart failure.Methods A total of 80 elderly chronic heart failure (CHF) patients who accepted treatments in our hospital from March 2012 to December 2013 were recruited,and 80 subjects undergoing health examinations served as the control group.The New York Heart Association (NYHA) functional classification in the experimental group was determined.Serum levels of S100B and NT-proBNP,left ventricular end diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were compared between the groups,and the correlation of the S100B level with NT proBNP,LVEF and the NYHA functional classification were analyzed.Results The serum S100B level was increased in the experimental group as compared with the control group [(91.4 ±31.9) pg/L vs.(74.9±26.0) pg/L,t=1.980,P=0.000].The serum NT-proBNP level was higher,LVEDD was longer,and LVEF was lower in the experimental group than in the control group (all P＜0.01).The serum S100B level was positively correlated with NT-proBNP (r=0.309,P=0.003) and the NYHA functional classification (r=0.508,P=0.001),and negatively correlated with the LVEF (r=-0.192,P=0.004).Conclusions The serum S100B level is increased in patients with CHF and negatively correlated with cardiac function,suggesting that the S100B protein may serve as a valuable tool for the diagnosis and assessment of CHF.However,more studies are needed to provide more evidence.
