It develops when arteries in the legs become clogged with plaque, fatty deposits that limit blood flow. Clogged arteries in the legs can cause symptoms such as claudication (pain due to too little blood flow) and increased risk for heart attack and stroke.

'These findings demonstrate that smoking is associated with PAD in a dose-dependent manner," says lead researcher Donald Clark, III, assistant professor of medicine at the University of Mississippi Medical Center, Jackson. 'This is particularly important in the African-American community and supports the evaluation of smoking-cessation efforts to reduce the impact of PAD in this population."

Even though PAD is...
