Air Pollution and Stroke

Air pollution has been linked to permanent decreased lung function in children as well as cancer and general poor health.

Now a new analysis shows that there is a direct link with strokes. This is a linear relationship, with increasing pollution closely related to increased risk of stroke.

Air pollution has been previously linked with an increased risk for heart attacks. Potential mechanisms include effects on the arteries, lower levels of oxygen in the blood, and increased risk for blood clots.

Given the substantial burden of stroke, especially in low- and middle-income countries, public health officials should maximize efforts to improve air quality to potentially reduce the global burden of stroke.
