Objective To investigate the association between malnutrition parameters and serum N-terminal pro-brain natriuretic peptide (NT-proBNP) level in male patients aged ≥ 80 years with normal ejection fraction.Methods A total of 197 elderly male patients aged 80 95 years (average 85.4±9.7) were enrolled.Each patient received echocardiograms following admission,and ejection fraction was calculated.Serum concentrations of NT-proBNP were measured by electrochemiluminescence immunoassay.Multiple Logistic regression analyses and receiver operating characteristic (ROC) curves were used to assess the association between malnutrition parameters and serum level of NT-proBNP.Results Serum NT-proBNP level was higher in patients with malnutrition than in the controls [(711.9±1063.3) ng/L vs.(1375.2-±1891.7) ng/L,P=0.006].Pearson correlation analysis showed that the malnutrition parameters such as body mass index (BMI),blood hemoglobin,albumin and pre-albumin were negatively correlated with serum NT proBNP level (all P＜0.05).Logistic regression analysis showed that BMI and serum pre albumin level were independently associated with serum NT-proBNP level elevation (P=0.028 and 0.006,respectively).ROC curve analysis showed that the malnutrition parameters could predict the serum NT-proBNP level elevation.The area under the ROC curves for BMI,levels of blood hemoglobin,albumin and prealbumin in predicting serum NT proBNP level elevation was 0.7 (P=0.002),0.7 (P=0.004),0.6 (P=0.036),0.6 P=0.002),the sensitivity was 75.5％,51.0％,38.8％,89.8％,and the specificity was 54.4％,70.2 ％,84.2％ and 31.6 ％,respectively.Conclusions The malnutrition parameters including BMI,blood hemoglobin,albumin and pre-albumin can predict serum NT-proBNP level elevation.BMI and serum pre-albumin level are independently associated with serum NT-proBNP level elevation in male patients aged ≥ 80 years with normal ejection fraction.
