Abstract P416: Higher Quality Diet is Associated With Lower Serum Levels of NT-proBNP

Introduction: N-terminal pro-brain-type natriuretic peptide (NT-proBNP) is widely used as a diagnostic biomarker for heart failure. Higher diet quality is associated with lower risk of cardiovascular disease. However, the association between diet and subclinical cardiovascular disease, as assessed by biomarker concentrations, is less well-studied. Hypothesis: We hypothesized that higher diet quality, assessed by the Healthy Eating Index-2015 (HEI-2015), would be associated with lower serum levels of NT-proBNP. Methods: We included 9,782 adults from the National Health and Nutrition Examination Survey (NHANES), 1999-2004. The HEI-2015 ranges from 0 to 100, with higher scores indicating better diet quality, and was categorized into sex-specific quintiles. Weighted multivariable linear regression models were used to estimate associations between the overall HEI-2015 score as well as its 13 components and log-transformed NT-proBNP. Results: Among 9,782 participants, mean age was 45 years, 48% were men, and 72% were non-Hispanic White adults. After adjusting for sociodemographic characteristics, lifestyle factors, and medical history, persons in the highest HEI-2015 quintile had a 10.0% lower NT-proBNP level compared to those in the lowest HEI-2015 quintile (95% CI: -17.7% to -2.6%). There was a dose-response relationship between HEI-2015 and NT-proBNP ( Figure ). For each 1-unit higher sodium and added sugars score, NT-proBNP was lower by 7.7% and 6.8% respectively (95% CI: -13.8 % to -2.2%, and 95% CI: -13.1% to -0.9% respectively). Conclusion: Higher diet quality, especially lower intakes of sodium and added sugars, was associated with lower serum levels of NT-proBNP.
