High blood pressure stalks many Americans

"It's one of medicine's mantras: If you have high blood pressure, taking steps to lower it will have a dramatic impact on your risk of stroke, heart disease and more. But 70% of people with high blood pressure still aren't doing a good enough job controlling it, according to a U.S. Centers for Disease Control and Prevention study. 'High blood pressure is clearly associated with stroke, and it's a very preventable and treatable condition, but a lot of people still aren't doing what they should,' said Dr. Keith Siller, medical director of the Comprehensive Stroke Care Center at New York University Langone Medical Center in New York City" - HealthDay
