Air Pollution and Hearts

How traffic pollution damages the heart

Living close to a busy road can damage your heart - and now we're closer to understanding why.

Previous studies had suggested that people living in polluted areas are more at risk of heart disease. For example, a study published in The New England Journal of Medicine last year showed that women in 36 American cities were more likely to develop heart disease if the air they breathed was rich in particles measuring 2.5 micrometres or less in diameter - known as PM2.5s - which are present in car exhaust fumes.

It now seems that a greater hazard may be posed by so-called "ultrafine" particles, about a dozen times smaller at 0.18 micrometres wide. The latest study in mice has shown that they clog up arteries with fatty atherosclerotic deposits, and chemically alter "good" cholesterol, or high-density lipoprotein (HDL) cholesterol, reducing its beneficial effects.
