Heart disease is the leading cause of death in the United States. Stroke is the fifth leading cause of death in the United States. Together, heart disease and stroke, along with other cardiovascular disease, are among the most widespread and costly health problems facing the Nation today, accounting approximately $320 billion in health care expenditures and related expenses annually. Knowing the signs of a stroke is the first step in stroke prevention. A stroke, sometime called brain attack, occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die. If a stroke is not caught early, permanent brain damage or death can result.

What is High Blood Pressure? Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into blood vessels, which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure. What Is "Normal" Blood Pressure? A blood pressure reading is written like this: 120/80. It's read as "120 over 80." The top number is called the systolic, and bottom number is called the diastolic. The ranges are: • Normal: Less than 120 over 80 (120/80) • Elevated: 120-129/less than 80 • Stage 1 high blood pressure: 130-139/80-89 • Stage 2 high blood pressure: 140 and above/90 and above • Hypertension crisis: higher than 180/higher than 120 -- See a doctor right away If your blood pressure is above the normal rang
