Particulate Air Pollution and DVT Risk

In this case-control study, risk for deep venous thrombosis rose by 70% for each 10-μg/m³ increase in exposure to particulate-matter air pollutants.

Particulate air pollution is associated with excess risks for heart disease and stroke. In a case-control study, conducted in northern Italy, researchers assessed whether such pollution also might be linked to venous thrombosis. A total of 871 patients who were diagnosed between 1995 and 2005 with lower-limb deep venous thrombosis (DVT) and 1210 healthy controls were enrolled in the investigation. The researchers estimated participants’ exposure to particulate-matter air pollutants <10 µm in diameter (PM₁₀) during the year before DVT diagnosis (cases) or examination (controls), based on monitored levels of PM₁₀ in nine geographic regions.

Mean PM₁₀ exposure during the year before diagnosis or examination varied by region, ranging from 12 to …
