THURSDAY, Dec. 2 (HealthDay News) -- Maintaining a healthy lifestyle can cut your risk for first-time stroke by 80 percent, according to new guidelines from the American Heart Association and the American Stroke Association.
Also, as more Americans use hospital emergency departments for primary health care, ER doctors are in a position to identify those at high risk for stroke, make referrals and begin preventive therapy, the guidelines point out.

As the U.S. population ages and obesity increases, more strokes are occurring -- 795,000 a year, 77 percent of them first-time -- but deaths from stroke have decreased, experts say.
"There has been about a 30 percent decrease in stroke-related mortality," said Dr. Larry B. Goldstein, director of the Duke Stroke Center in Durham, N.C., and lead guideline author.
"We think a good part of the reduction is due to improved prevention," he said.
A healthy lifestyle, which includes not smoking, maintaining a healthy weight, exercising and eating a diet rich in fruits and vegetables, has the biggest impact on preventing stroke, Goldstein said.
"There is nothing we are going to do in medicine to beat that," he said.
Keeping cholesterol and blood pressure low are also important for reducing stroke risk, Goldstein added.
The guideline authors address the whole stroke spectrum: ischemic stroke, which involves a blocked blood vessel in the brain; non-ischemic (hemorrhagic) stroke, in which a ruptured vessel bleeds in the brain; and transient ischemic attack (TIA), a temporary stroke that can be an indicator of risk for a more serious stroke.
Prevention of each type of stroke is basically the same, Goldstein stated. "People need to take charge of their own lives," he said. "The best w
