Definition of diastolic blood pressure

Diastolic blood pressure is the pressure in the arteries when the heart is at rest between beats. It is the lower number in a blood pressure reading and is an important indicator of heart health. A normal diastolic blood pressure reading is typically below 80 mmHg. High diastolic blood pressure can indicate an increased risk of heart disease, stroke, and other health problems.

Diastolic blood pressure is the pressure in the arteries when the heart is resting between beats. It is the lower of the two numbers in a blood pressure reading, such as 120/80 mmHg. Diastolic blood pressure is important because it can indicate the presence of high blood pressure, or hypertension, which is a major risk factor for heart disease and stroke.
