Associations Between Lead and Cadmium Exposure and Subclinical Cardiovascular Disease in U.S. Adults.

ABSTRACT: The impact of lead and cadmium exposure on subclinical cardiovascular disease (CVD), indicated by elevated high-sensitivity cardiac troponin (hs-cTnT) and N-terminal pro b-type natriuretic peptide (NT-proBNP) remains uncertain. We analyzed data from participants aged 20 and older, without overt CVD, in the National Health and Nutrition Examination Survey (NHANES; 1999-2004). Elevated lead and cadmium levels were defined as 3.5 μg/dL and 1.0 μg/L (inductively coupled plasma mass spectrometry) and 3.8 μg/dL and 0.9 μg/L (atomic absorption spectrometry), respectively. Elevated hs-cTnT was ≥ 19 ng/L, and elevated NT-proBNP was ≥ 125 pg/mL. Multivariate logistic regression estimated the odds ratios (OR) and 95% confidence intervals (CI) for elevated biomarkers. Among 10,197 participants (mean a
