The Need for Speed: Two New Studies on Stroke

Date:11/2/2007

ANN ARBOR, Mich., Nov. 2 /PRNewswire-USNewswire/ -- Every 45 seconds, an American suffers a stroke. Every minute one of those individuals goes without treatment, more brain cells die. And every hour that passes before victims get to the hospital, the less likely they are to be eligible for the most effective treatment.

But despite all this, 69 percent of stroke victims don't reach the hospital in the first three hours after their stroke symptoms begin, according to a new study led by the University of Michigan Stroke Program and published in the journal Stroke.

That delay keeps many patients from receiving tPA, the only approved treatment for stroke caused by blood clots in the brain. If it's given intravenously within the first three hours of the start of a stroke, or injected directly into the brain within six hours, tPA can break up clots and stop or slow the damage caused by strokes.

But in the new study, only 44 percent of patients experiencing full-blown clot-based strokes got to the hospital even within six hours of the start of their symptoms - and 36 percent didn't get there until more than 12 hours had passed. The study was conducted between 2000 and 2005 in Corpus Christi, Texas - an area with no major university hospitals, making it a "real world" snapshot of stroke care in America.

The researchers say their findings confirm previous studies and underscore the importance of public education efforts to help everyone understand that when a stroke strikes, they should call 911 right away.

In fact, in a second paper published in Stroke, a U-M-led team describes the positive effects of an education effort aimed at middle-schoolers in the same area of Texas. After three years in which some children received four hours a year of stroke-related instruction and some didn't, a test showed the first group of children was much more likely to know how to recognize a stroke and to indicate they would call 911 if they witnessed
