Deep Vein Thrombosis And Complications Increased By Dirty Air
Italy- In a cooperative study done between researchers in Italy and scientists from Harvard University evidence has been uncovered which gives support to a link between blood clots and air pollution.
The level of air pollution, even at levels deemed “acceptable,” by the EPA can increase the risk to patients of deep vein thrombosis, or clotting in the veins.
Researchers from Italy and Harvard University studied 870 people who had Deep Vein Thrombosis from 1995 to the year 2000. The researchers looked at the air pollution levels in the year just before these patients were diagnosed, and compared these results with 1,210 people that matched up who did not have the DVT condition.
For every 10 microgram per cubic meter rise above 12 micrograms per cubic meter of air, the risk of developing deep vein thrombosis goes up 70 percent.
The particulate air pollution standard in the United States is 150 micrograms per cubic Meter of air. It is believed that very fine and fine particles of pollution are causing most of the health risks that are linked to specific air pollution.
The EPA decides on the standards and the standard for very tiny particles may need to be increased to a higher safety margin.

Washington: It's not just your lungs that are at risk from air pollution - a new study has linked this modern menace to the formation of blood clots as well.
The study, by Harvard researchers, found that every 10 microgram per square metre increase in particulate matter upped the risk of clot development by a whopping 70 per cent.
Exposure to fine particles of solid and liquid chemicals, released by burning fossil fuels, has already been linked to increased risk of heart disease and stroke.
Andrea Baccarelli of Harvard analysed exposure to particulate matter among 870 patients diagnosed with such clots (deep vein thrombosis) between 1995 and 2005.
These patients, along with 1,210 controls who were free of the condition, were assigned to one of nine geographic regions based on where they lived at the time of the study.
The researchers then used the average concentration of particulate matter for each area to estimate the level of exposure over the year before diagnosis (for cases) or examination (for controls).
Individuals with deep vein thrombosis tended to have a higher exposure to particulate air pollution than controls - and for every increase in particulate matter of 10 micrograms per square metre the previous year, the risk of deep vein thrombosis increased 70 percent.
The association between particle exposure and blood clots was stronger in men than in women, and disappeared among women taking oral contraceptives or hormone therapy.
Such hormone therapies are independent risk factors for deep vein thrombosis, which is also confirmed in this study by the higher prevalence of oral contraceptive and hormone use in the cases compared with the controls, Baccarelli said.
According to experts, particulate matter ranks as the 13th leading cause of global mortality, causing an estimated 800,000 deaths annually.
Findings of the study have appeared in the latest issue of the Archives of Internal Medicine.

Air pollution increases the risk of deep vein thrombosis (DVT) -- dangerous blood clots in the veins -- even at pollution levels the EPA deems "acceptable."

Harvard researcher Andrea Baccarelli, MD, PhD, and colleagues in Italy studied 870 people diagnosed with DVT from 1995 to 2005. They compared their particulate air pollution exposure in the year before their diagnosis to that of 1,210 matched people without DVT.

They found that DVT risk goes up 70% for every 10 microgram-per-cubic-meterrise in particulate air pollution above 12 micrograms per cubic meter of air (the lowest pollution level measured in the study).....

Air pollution affects the heart and blood vessels even more than the lungs, notes Robert D. Brook, MD, a University of Michigan expert on the cardiovascular effects of air pollution. An editorial by Brook accompanies the Baccarelli report in the May 12 issue of Archives of Internal Medicine.
