ABSTRACT: Objective
Under physiological conditions brain natriuretic peptide (BNP) is inversely associated with metabolic risk factors, but under pathological conditions these associations may tend to plateau.Material and methods
5597 individuals in the Multi-Ethnic Study of Atherosclerosis (MESA), 45-84years of age, free of overt cardiovascular disease in 2000-02 and then again in 2003-05 participated in this study. Associations between NT-proBNP and BMI, blood lipids, homeostasis model of insulin resistance (HOMA-IR) using linear regression models were adjusted for age, race, sex, BMI, % of energy from saturated fats, intentional exercise, statin use, antihypertensive medication use, diabetes and glomerular filtration rate. The inflection points (IP) at which these associations became nonlinear were determined using linear splines with knots at different levels of NT-proBNP.Results
Participants with NT-proBNP ≥100pg/mL (29%) tended to be older, on statins and anti-hypertensive medications vs. those with NT-proBNP <100pg/mL. The IP point varies among variables and ranged from 50-120pg/mL. NT-proBNP
