Stroke and air pollution. A worldwide public health problem

After myocardial infarction, stroke is now associated with air pollution. From local data and literature, we report the strength of the association between air pollution and stroke. We try to understand the biological mechanisms between exposure to air pollutants and stroke risk. The association between air pollution and stroke is strong, confirmed and real. Air pollution and small particulate matter are the most toxic. Patients with classical neuro-vascular risk factors or a history of stroke or transient ischemic attack are at risk of stroke induced by air pollution. Air pollution is a serious modifiable risk factor for stroke and a silent killer inducing stroke. This new neuro-vascular risk factor is useful for public health policies.
