Introduction: It has been shown that B type natriuretic peptide (BNP) level can indicate cardiovascular disease. However, the association between BNP and metabolic risk factors is unknown. The aim of this study was to investigate the correlation between N-terminal pro-B type natriuretic peptide (NT-proBNP) and metabolic risk factors.
Material and methods: A total of 11,508 subjects were selected from those who underwent health examinations in our hospital. NT-proBNP, waist circumference, blood pressure, fasting plasma glucose and lipid profile were measured. The level of NT-proBNP was measured and classified into four stratifications (BNP ≥ 20 pg/ml, ≥ 40 pg/ml, ≥ 60 pg/ml, and ≥ 80 pg/ml) to analyze the relationship between BNP and metabolic risk factors.
Results: B type natriuretic peptide increased gradually with increasing age (p < 0.001). The BNP levels were significantly higher in women than in men (p < 0.001). Multivariate regression analysis showed a positive association between NT-proBNP levels and systolic blood pressure (p < 0.001), fasting plasma glucose (p < 0.05), and total cholesterol (p < 0.001 in women). The NT-proBNP levels were inversely associated with diastolic blood pressure, waist circumference, triglyceride, high-density lipoprotein, and LDL cholesterol. Logistic regression analysis demonstrated a close relationship between NT-proBNP and systolic blood pressure, fasting plasma glucose, and total cholesterol. In the BNP ≥ 60 pg/ml group, odds ratio (OR) values were 1.80, 1.56 and 1.54 (female) and 3.74, 1.59 and 1.51 (male), respectively. In the BNP ≥ 80 pg/ml group, OR values were 2.45, 1.65 and 1.84 (female) and 4.61, 1.66 and 1.75 (male), respectively.
Conclusions: NT-proBNP was independently associated with the main metabolic risk factors (systolic blood pressure, fasting plasma glucose, and total cholesterol). These findings suggest that the combined determination of NT-proBNP and the main metabolic risk factors could be important in assessing cardiovascular morbidity.
