Title Associations between particulate sulfate and organic carbon exposures and heart rate variability in patients with or at risk of cardiovascular diseases
Bibliographic information June 2007, Vol.49, No.6, p.610-617. Illus. 42 ref.
Abstract To determine whether specific components in fine particles are associated with heart rate variability (HRV), 46 patients with or at risk of cardiovascular diseases were recruited to measure 24-hour HRV by ambulatory electrocardiographic monitoring. Fixed-site air-monitoring stations were used to represent participants' exposures to particles with aerodynamic diameters less than 10Ám (PM10) and 2.5Ám (PM2.5), and particulate components of sulfate, nitrate, organic carbon and elemental carbon, and gaseous pollutants. It was found that HRV reduction was associated with sulfate, organic carbon and PM2.5, but not with the other pollutants in single-pollutant models. Sulfate was found to remain in significant association with HRV reduction adjusting for organic carbon and PM2.5 in three-pollutant models.
