The lower number of a blood pressure reading signifying the myocardial and arterial relaxation between pump strokes. Too close to the higher number (systolic) usually signifies inadequate relaxation of the heart and arteries between heartbeats.
The pressure exerted by the blood against the arterial wall during DIASTOLE. This is the lowest blood pressure in the cardiac cycle. A normal reading of diastolic pressure in a healthy adult at rest is 70 mm Hg. (See HEART.)... diastolic pressure
impairment of heart function due to increased stiffness of the left *ventricle, which results in reduced capacity of the heart to fill with blood during diastole. The clinical effects of this are described as heart failure with normal ejection fraction (HEFNEF). Compare systolic dysfunction.... diastolic dysfunction
