High blood pressure - (hypertension)
High blood pressure (hypertension) is often called the silent killer because you can have it for years without knowing it.
Blood pressure is determined by the amount of blood your heart pumps and the amount of resistance to blood flow in your arteries. Your blood pressure normally varies during the day. It can even vary slightly with each beat of the heart. It increases during activity and decreases with rest.
Under new, stricter national blood pressure guidelines issued in May 2003, a resting blood pressure reading below 120/80 millimeters of mercury (mm Hg) is normal. If your resting blood pressure is consistently 140/90 mm Hg or higher, you have high blood pressure. A reading in between these levels places you in the prehypertensive category. Under the new guidelines, a reading of 115/75 is the level above which your risk of cardiovascular complications starts to increase.
Many people may not view a blood pressure above 115/75 as life-threatening because there are few, if any, symptoms. But uncontrolled high blood pressure can increase your risk of stroke, heart attack, heart failure and kidney failure. Fortunately, high blood pressure can be detected with a simple test — and once you know you have high blood pressure, you can work with your doctor to control it.
