A Case–Control Analysis of Exposure to Traffic and Acute Myocardial Infarction
(National Institute of Environmental Health Sciences, 2006)
Background: Long-term exposure to particulate air pollution has been associated with an increased risk of dying from cardiopulmonary and ischemic heart disease, yet few studies have evaluated cardiovascular end points other ...
Opposing Effects of Particle Pollution, Ozone, and Ambient Temperature on Arterial Blood Pressure
(National Institute of Environmental Health Sciences, 2012)
Background: Diabetes increases the risk of hypertension and orthostatic hypotension and raises the risk of cardiovascular death during heat waves and high pollution episodes. Objective: We examined whether short-term ...
Mortality Risk Associated with Short-Term Exposure to Traffic Particles and Sulfates
(National Institute of Environmental Health Sciences, 2007)
Background: Many studies have shown that airborne particles are associated with increased risk of death, but attention has more recently focused on the differential toxicity of particles from different sources. Geographic ...
Short-term Effects of Carbon Monoxide on Mortality: An Analysis within the APHEA Project
(National Institute of Environmental Health Sciences, 2007)
Objectives: We investigated the short-term effects of carbon monoxide on total and cardiovascular mortality in 19 European cities participating in the APHEA-2 (Air Pollution and Health: A European Approach) project. Methods: ...
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, ...
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 ...
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 ...
Effects of air pollution on heart rate variability: the VA Normative Aging Study
(National Institue of Environmental Health Sciences, 2004)
Reduced heart rate variability (HRV), a marker of poor cardiac autonomic function, has been associated with air pollution, especially fine particulate matter [< 2.5 μm in aerodynamic diameter (PM\(_{2.5}\))]. We examined ...
