TUESDAY, Dec. 20 (HealthDay News) -- Fumes belched from diesel-engines may be especially tough on the human cardiovascular system, new research reveals.
In a carefully controlled study, the arteries of healthy volunteers exposed to diesel exhaust lost part of their ability to expand, while their blood became more likely to clot.
Response to the vasodilators was reduced significantly after the diesel exposure, and levels of an enzyme that helps keep clots from forming were reduced, the researchers reported.

A number of real-world studies have linked diesel fume exposure to heart attacks and other cardiovascular problems.

It's not clear whether the findings apply to gasoline-powered engines, because their emissions are very different from those of diesel-powered engines. In particular, diesel exhaust generates 100 times more pollutant particles.
