More and more evidence shows a link between cardiovascular disease and air pollution. There is a specific air pollution particle called PM2·5 that is produced from car engines, fireplaces and power plants. These particles are small enough to be breathed deep into the lungs where they can cause chronic inflammation. Researchers recently studied adults from 21 low-income, middle-income, and high-income countries to compare long-term outdoor exposure to this particle, PM2·5 , with the risk of having a heart attack and stroke. They found that the more exposure to air pollution, the greater risk for cardiovascular disease. In conclusion, PM2·5 is an important global risk factor for cardiovascular disease, especially for stroke. There is a need to reduce air pollution especially where air pollution levels are highest.
