Air pollution in deep vein thrombosis link
Long-term exposure to air pollution alters coagulation function and raises the risk of deep vein thrombosis, a US study finds.
The researchers examined the association between exposure to particulate matter of less than 10[micro]m in aerodynamic diameter and DVT in 870 patients and 1,210 controls.
The higher the level of particulate matter, the shorter was the prothrombin time in cases of DVT. Each increase of 10[micr]g/m[cubed] increase in particulate matter raised the risk of DVT by 70%.
