Men at higher risk of heart attack, stroke, when exposed to diesel exhaust
Pollution through improved road diesel fuel in vehicles is produced by a cascade of conditions that can lead to heart attack or stroke, which suggested the researchers report in a small study in the American Heart Association Scientific Sessions presented in 2007. UK and Swedish researchers found that diesel exhaust increased clot formation and activity of blood platelets in healthy volunteers - which can lead to a heart attack or stroke. The results of the study are closely related to previous observational studies and epidemiological studies showing that shortly after exposure to the pollution of air traffic, the people are connected rather suffer a heart attack, said Andrew Lucking, Mr.D., author of the study and researcher in cardiology at the University of Edinburgh in the
UK. This study shows that when a person is exposed to relatively high levels of diesel exhaust for a short period, the blood is more likely to clot. This could lead to a blocked vessel resulting in heart attack or stroke.The double-blind, randomized cross-over study included 20 healthy men, 21 to 44. Were separately filtered air (serving as control) and diluted diesel exhaust at 300 micrograms per cubic meter (mcg/m3), a level comparable to exposure from door to door on a busy road show. The researchers carried out the shooting in a room specially built diesel exposure. In two hours and six hours after exposure, the researchers were able to slip a small amount of blood by an infusion of participants.They measured clot formation, coagulation, platelet activation and
inflammatory markers after each exposure.To measure clot formation, the researchers both low and high shear rates, the flow conditions within the body of new blood vessels used. Compared to filtered air, breathing air with diluted diesel exhaust increased clot formation in the low shear chamber by 24.2 percent and the high shear chamber by 19.1 percent. This was seen at two and six hours after diesel exposure. The researchers Canada online pharmacy buy ciprofloxacin purchase uk
