What does the diastolic blood pressure number mean? The diastolic blood pressure number or the bottom number indicates the pressure in the arteries when the heart rests between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal. A diastolic blood pressure number of 90 or higher, on repeated measurements, is considered to be hypertension or high blood pressure.
How to Lower Diastolic Pressure. Your blood pressure reading has an upper and a lower number, called systolic and diastolic pressures, respectively. The diastolic pressure indicates the heart's pressure when it is relaxing between beats. A diastolic pressure above 90 is considered high because it can lead to a heart attack or a stroke.
