NPPB and diabetes mellitus: Using multivariable models, we identified several factors associated with greater increases in galectin‐3 levels over ≈15 years: age, male sex, black race, current smoking, blood pressure (systolic blood pressure, pulse pressure, antihypertensive medications), metabolic risk factors (fasting glucose, diabetes mellitus, body mass index), and cardiac biomarkers (baseline galectin‐3, NT‐proBNP, hs‐TnI).
