Blood pressure is the pressure of blood in your arteries. Blood pressure is measured in millimeters of mercury (mm Hg).
High blood pressure is a chronic medical condition where the blood pressure in the arteries is elevated. It is a risk factor that can increase your chance of developing heart disease, a stroke, aneurysms and other serious conditions, as a rule, the higher the blood pressure, the greater the risk.
Blood pressure readings are usually given as two numbers -- for example, 120 over 80 (written as 120/80 mmHg). One or both of these numbers can be too high.
The top number is called the systolic blood pressure, and the bottom number is called the diastolic blood pressure.
