Acute effects of fine particulate air pollution on ST segment height: A longitudinal study
He, Fan; Shaffer, Michele L.; Rodriguez-Colon, Sol; Bixler, Edward O.; Vgontzas, Alexandros N.; Williams, Ronald W.; Wu, Rongling; Cascio, Wayne E.; Liao, Duanping (2010)Background The mechanisms for the relationship between particulate air pollution and cardiac disease are not fully understood. Air pollution-induced myocardial ischemia is one of the potentially important mechanisms. ... -
Cardiovascular effects in patrol officers are associated with fine particulate matter from brake wear and engine emissions
Riediker, Michael; Devlin, Robert B.; Griggs, Thomas R.; Herbst, Margaret C.; Bromberg, Philip A.; Williams, Ronald W.; Cascio, Wayne E. (East Carolina University, 2004-12-09)Background: Exposure to fine particulate matter air pollutants (PM2.5) affects heart rate variability parameters, and levels of serum proteins associated with inflammation, hemostasis and thrombosis. This study investigated ... -
Coarse Particulate Matter (PM2.5 - 10) Affects Heart Rate Variability, Blood Lipids, and Circulating Eosinophils in Adults with Asthma
Yeatts, Karin; Svendsen, Erik; Creason, John; Alexis, Neil E.; Herbst, Margaret C.; Scott, James; Kupper, Lawrence; Williams, Ronald W.; Neas, Lucas M.; Cascio, Wayne E.; Devlin, Robert B.; Peden, David B. (East Carolina University, 2007-05)INTRODUCTION: We investigated whether markers of airway and systemic inflammation, as well as heart rate variability (HRV) in asthmatics, change in response to fluctuations in ambient particulate matter (PM) in the coarse ...
