The top number is the maximum pressure your heart exerts while beating (systolic pressure), and the bottom number is the amount of pressure in your arteries between beats (diastolic pressure). The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure. For example, if your resting blood pressure is 120/80 millimeters of mercury (mm Hg), your pulse pressure is 40. For adults older than age 60, a pulse pressure greater than 60 can be a useful predictor of heart attacks or other cardiovascular disease; this is especially true for men. In some cases a low pulse pressure (less than 40) may indicate poor heart function.
