In populations, blood pressures fit a normal distribution, but the attendant risks of heart disease and stroke increase curvilinearly with increasing levels of blood pressure, without any obvious breakpoint ( Fig. 63-1 ). Thus, the separation of normal from high blood pressure is arbitrary, and the definition of hypertension has been a moving target.

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity- and just as too much air pressure can cause damage to a balloon, too much blood pressure can harm healthy arteries.

Hypertension is the term doctors use for high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as 2 numbers. For example, 140 over 90 (written as 140/90. The top number is your systolic pressure, the pressure created when your heart beats. It is considered high if it is consistently over 140; The bottom number is your diastolic pressure, the pressure inside blood vessels when the heart is at rest. It is considered high if it is consistently over 90. Either or both of these numbers may be too high. Pre-hypertension is when your systolic blood pressure is between 120 and 139 or your diastolic blood pressure is between 80 and 89 on multiple readings. If you have pre-hypertension, you are more likely to develop high blood pressure at some point. See also: Blood pressure
