Maybe you've got a serious case of air pollution going on at your house. Because you see, The World Health Organization Monitoring Survey of Trends and Determinants in Cardiovascular Disease (the "MONICA" survey) took place in Augsburg, in Southern Germany during the winter of 1984-1985.
Over 4,000 randomly selected adults participated, and received electrocardiograms to measure their resting heart rate, and donated blood samples to measure plasma viscosity. Electrocardiograms were administered again in 1987-1988.
In January 1985, an air pollution episode occurred throughout central Europe, with elevated concentrations of sulfur dioxide, total suspended particulates, and carbon monoxide.
During the air pollution episode, higher heart rates were observed for men and women, after adjusting for cardiovascular risk factors and weather.
An elevated resting heart rate is a risk factor for death and fatal heart disease, and may signal changes in the autonomic control of the heart, that might partially account for the adverse health effects observed in association with air pollution.
One hypothesis is that increased plasma viscosity might lead to constricted blood flow in the heart (ischemia), which can be fatal in people with severe coronary heart disease.
During the air pollution episode, increases in plasma viscosity were observed, and persisted after adjusting for other cardiovascular risk factors and weather.
German researcher Annette Peters, et al. conclude that "the increased plasma viscosity observed in these analyses of a cross-sectional survey might therefore represent a part of the pathophysiological chain linking high ambient air pollution to increased mortality and hospital admissions for cardiovascular diseases."
An alternate hypothesis is proposed by Professsor Anthony Seaton of the University of Aberdeen Medical School. He collected blood samples from 112 elderly people in two cities in the U.K. over an 18-month period, and examined various blood values in comparison to PM10 concentrations.
Based on the analysis, Seaton suggests that inhalation of some component of PM10 may cause sequestration of red blood cells, which may explain the cardiovascular effects reported in other studies.
So, my recommendation is that you move into a bubble. Barring that, you should head on down to Cheers and have yourself a beer. Though maybe not. The air pollution can be pretty high down here on any given night also.
Cheers!
