Firefighters Have Narrower-Than-Normal Arteries, Study Finds
Date:3/13/2009

Experts cite smoke, eating habits and sleep patterns as potential causes,,

FRIDAY, March 13 (HealthDay News) -- Burning buildings might not be the only risks that firefighters face. They also appear to be more likely than their peers in other professions to have prematurely narrowed arteries, increasing their risk for strokes and heart attacks, according to a new study.

In fact, 22 percent of a group of 77 firefighters studied by researchers at the University of Kansas averaged 39 years old but had the blood vessels of 52-year-olds because of significant plaque buildup in their carotid arteries.

"These men, as young as they are, for some reason have a high rate of early development of vascular disease, asymptomatic as it is," said Dr. Patrick Moriarty, director of the Atherosclerosis and LDL Apheresis Center at the University of Kansas Medical Center and the study's lead researcher. "What it means is that we have to find a way to make their job have less risk potential in terms of less cardiovascular risk."

The findings were presented March 12 at the American Heart Association's conference on cardiovascular disease in Palm Harbor, Fla.

The demands of firefighters' jobs and their health needs often conflict, Moriarty explained. The stress of being on call for 48 hours, for instance, takes a toll on the body, he said. And, in addition, firefighters need high-calorie meals because, if they have to quickly leave to fight a fire, they might not have another meal for 24 hours, Moriarty said.

Dr. Gregg C. Fonarow, a professor of medicine and associate chief of the cardiology division at the University of California, Los Angeles, said that exposure to small particulate matter in smoke that occurs at fires also is harmful. Smoke, he said, provokes inflammation, which is associated with heart disease and stroke.

Also, many firefighters sleep during the day and work at night, which might be a p
