Iron Metabolism Genes, Low-Level Lead Exposure, and QT Interval
(National Institute of Environmental Health Sciences, 2008)
Background: Cumulative exposure to lead has been shown to be associated with depression of electrocardiographic conduction, such as QT interval (time from start of the Q wave to end of the T wave). Because iron can enhance ...
Low-Level Lead Exposure, Metabolic Syndrome, and Heart Rate Variability: The VA Normative Aging Study
(National Institute of Environmental Health Sciences, 2006)
Background: Altered heart rate variability (HRV), a marker of poor cardiac autonomic function, has been associated with sudden cardiac death and heart failure. Objective: We examined the association of low-level lead ...
Lead Concentrations in Relation to Multiple Biomarkers of Cardiovascular Disease: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2012)
Background: Lead exposure has been associated with cardiovascular disease (CVD) in animal and human studies. However, the mechanisms of action have not been fully elucidated. We therefore examined the relationship between ...
Association of Cumulative Lead Exposure with Parkinson’s Disease
(National Institute of Environmental Health Sciences, 2010)
Background: Research using reconstructed exposure histories has suggested an association between heavy metal exposures, including lead, and Parkinson’s disease (PD), but the only study that used bone lead, a biomarker of ...
