As Years Spent Obese Rise, So Do Heart Risks

There's more bad news for overweight Americans: A 30-year study finds the risk for heart disease rises the longer someone is obese. "Each year of obesity was associated with about a 2 to 4 percent higher risk of subclinical coronary heart disease," said study lead author Jared Reis, an epidemiologist with the U.S. National Heart, Lung, and Blood Institute. "Subclinical" heart disease means damage to arteries that shows up in markers such as calcium buildup on arterial walls, but has not yet developed into symptomatic illness. http://www.nlm.nih.gov/medlineplus/news/fullstory_138761.html
