Air Pollution and ST-Segment Depression in Elderly Subjects
(National Institue of Environmental Health Sciences, 2005)
Increased levels of daily ambient particle pollution have been associated with increased risk of cardiovascular morbidity. Black carbon (BC) is a measure of the traffic-related component of particles. We investigated ...
The Relationship Between Ambient Air Pollution and Heart Rate Variability Differs for Individuals with Heart and Pulmonary Disease
(National Institute of Environmental Health Sciences, 2005)
Associations between concentrations of ambient fine particles [particulate matter < 2.5 μm aerodynamic diameter (PM\(_{2.5}\))] and heart rate variability (HRV) have differed by study population. We examined the effects ...
The Concentration-Response Relation Between PM\(_{2.5}\) and Daily Deaths.
(National Institute of Environmental Health Sciences, 2002)
Particulate air pollution at commonly occurring concentrations is associated with daily deaths. Recent attention has focused on the shape of the concentration-response curve, particularly at low doses. Several recent ...
Air conditioning and source-specific particles as modifiers of the effect of PM(10) on hospital admissions for heart and lung disease.
(National Institute of Environmental Health Sciences, 2002)
Studies on acute effects of particulate matter (PM) air pollution show significant variability in exposure-effect relations among cities. Recent studies have shown an influence of ventilation on personal/indoor-outdoor ...
Air Pollution, Smoking, and Plasma Homocysteine
(National Institute of Environmental Health Sciences, 2006)
Background: Mild hyperhomocysteinemia is independently associated with an increased risk of cardiovascular disease. Air pollution exposure induces short-term inflammatory changes that may determine hyperhomocysteinemia, ...
The effect of weather on respiratory and cardiovascular deaths in 12 U.S. cities.
(National Institute of Environmental Health Sciences, 2002)
We carried out time-series analyses in 12 U.S. cities to estimate both the acute effects and the lagged influence of weather on respiratory and cardiovascular disease (CVD) deaths. We fit generalized additive Poisson ...
Baseline Repeated Measures from Controlled Human Exposure Studies: Associations between Ambient Air Pollution Exposure and the Systemic Inflammatory Biomarkers IL-6 and Fibrinogen
(National Institute of Environmental Health Sciences, 2009)
Introduction: Systemic inflammation may be one of the mechanisms mediating the association between ambient air pollution and cardiovascular morbidity and mortality. Interleukin-6 (IL-6) and fibrinogen are biomarkers of ...
The Effect of Particulate Air Pollution on Emergency Admissions for Myocardial Infarction: A Multicity Case-Crossover Analysis
(National Institute of Environmental Health Sciences, 2005)
Recently, attention has focused on whether particulate air pollution is a specific trigger of myocardial infarction (MI). The results of several studies of single locations assessing the effects of ambient particular matter ...
Reduction in Heart Rate Variability with Traffic and Air Pollution in Patients with Coronary Artery Disease
(National Institute of Environmental Health Sciences, 2009)
Introduction: Ambient particulate pollution and traffic have been linked to myocardial infarction and cardiac death risk. Possible mechanisms include autonomic cardiac dysfunction. Methods: In a repeated-measures study of ...
Is There Adaptation in the Ozone Mortality Relationship: A Multi-City Case-Crossover Analysis
(BioMed Central, 2008)
Background: Ozone has been associated with daily mortality, mainly in the summer period. Despite the ample literature on adaptation of inflammatory and pulmonary responses to ozone, and the link, in cohort studies, between ...
