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 ...
Diabetes, Obesity, and Hypertension May Enhance Associations between Air Pollution and Markers of Systemic Inflammation
(National Institute of Environmental Health Sciences, 2006)
Airborne particulate matter (PM) may lead to increased cardiac risk through
an inflammatory pathway. Therefore, we investigated associations
between ambient PM and markers of systemic inflammation among repeated
measures ...
Increased Risk of Paroxysmal Atrial Fibrillation Episodes Associated with Acute Increases in Ambient Air Pollution
(National Institute of Environmental Health Sciences, 2006)
Objectives: We reported previously that 24-hr moving average ambient air pollution concentrations were positively associated with ventricular arrhythmias detected by implantable cardioverter defibrillators (ICDs). ICDs ...
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 ...
Factors Affecting the Association between Ambient Concentrations and Personal Exposures to Particles and Gases
(National Institute of Environmental Health Sciences, 2005)
Results from air pollution exposure assessment studies suggest that ambient fine particles [particulate matter with aerodynamic diameter ≤ 2.5 μg (PM2.5)], but not ambient gases, are strong proxies of corresponding personal ...
Particulate air pollution, oxidative stress genes, and heart rate variability in an elderly cohort
(National Institute of Environmental Health Sciences, 2007)
Background and Objectives: We have previously shown that reduced defenses against oxidative stress due to glutathione S-transferase M1 (GSTM1) deletion modify the effects of PM[2.5] (fine-particulate air pollution of < 2.5 ...
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 ...
Differences in Heart Rate Variability Associated with Long-Term Exposure to NO2
(National Institute of Environmental Health Sciences, 2008)
Background: Heart rate variability (HRV), a measure of cardiac autonomic tone, has been associated with cardiovascular morbidity and mortality. Short-term studies have shown that subjects exposed to higher traffic-associated ...
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 ...
Ambient and Microenvironmental Particles and Exhaled Nitric Oxide Before and After a Group Bus Trip
(National Institute of Environmental Health Sciences, 2007)
Objectives: Airborne particles have been linked to pulmonary oxidative stress and inflammation. Because these effects may be particularly great for traffic-related particles, we examined associations between particle ...
