Abstract

Abstract : Air pollution poses a substantial but potentially modifiable threat to global health. It preferentially affects the respiratory and cardiovascular systems, and therefore there is a growing interest in the effects of this environmental exposure in stroke. 1 Air pollution is a global issue, but it particularly affects low and middle-income countries with fast growing economies. 1 An estimated 16.9% of the roughly 15 million strokes per year worldwide can be attributed to air pollution. 1, 2 Both short- 3 and long-term exposure to air pollution increase the risk for developing an ischemic stroke. 1 This association seems to primarily affect risk of strokes due to atherosclerosis, including large artery 4 and small vessel. 5 Air pollution might also acutely precipitate stroke, as suggested by daily incidence data. 6 Data suggest an association between short-term pollution and intracerebral hemorrhage 7 as well as a close temporal association between pollution and mortality after stroke. 3
