Facts about Stroke
1 Every 45 seconds,someone in America has a stroke.Every 3.1 minutes,someone dies of one.Stroke killed an estimated 167,661 people in 2000 and is the nation’s third leading cause of death,ranking behind diseases of the heart and all forms of cancer.Stroke is a leading cause of serious,long-term disability in the United States.
