title: [Particles in the outside air increase the risk of cardiovascular diseases].
abstract: Evidence accumulated during the mid-1990 s that ambient particulate air pollution aerosol particles may not only exacerbate respiratory diseases but also be a risk factor for cardiovascular disease exacerbation. The aim of the studies described here was to assess the impact of the 1985 smog episode on the risk factor profile in the randomly selected population-based sample of the MONICA survey 1984/85 (S1). During a 13-day period in January 1985 sulphur dioxide concentrations increased four times and concentrations of total suspended atmospheric particles doubled. The impact of this time period on plasma viscosity, plasma C-reactive protein concentrations, heart rate and blood pressure was investigated. Regression models were used to assess these associations adjusting for individual risk factors such as gender, age, body mass index, serum total cholesterol and HDL-cholesterol, smoking, physical activity and medication for cardiovascular diseases and for weather conditions during the survey period. An increase in plasma viscosity, C-reactive protein and heart rate was estimated during the air pollution episode. There was also an increase in blood pressure, but this appeared to be attributable to the weather conditions during the air pollution episode. All the four outcomes were associated with the sulphur dioxide concentrations and the total suspended particle concentrations during the survey. These results indicate that ambient air pollution, particularly ambient particulate air pollution may induce systemic inflammation and modulate the autonomic function of the heart. These pathomechanisms may contribute to the observed associations between ambient air pollution concentrations and cardiovascular disease exacerbation such as hospitalisation and mortality due to cardiovascular diseases.
