Diastolic Blood Pressure

During the circulation of blood, the blood pressure drops as it moves away from the heart through arteries, and toward the heart through veins.

Diastolic blood pressure (DBP) is a more potent cardiovascular risk factor than SBP until age 50; after that, Systolic blood pressure (SBP) is more important.

Diastolic blood pressure varies depending on the activity, surrounding temperature, diet-taken, state-of-mind (emotional), physical posture and medicine in use.

What is diastolic blood pressure?

For every heartbeat, blood pressure varies between systolic and diastolic blood pressures. Diastolic is the pressure drop in the arteries, which generates near the beginning of the cardiac cycle when the ventricles are filling with blood.

Blood pressure readings are measured in millimeters of mercury (mmHg), and it is noted as two numbers, example 110 over 70 (i.e. 110/70). The bottom number (70 mmHg) is the diastolic blood pressure reading. It represents the minimum pressure generated when the heart relaxes. Diastolic blood pressure is the blood pressure number between heartbeats (when the heart rests).

Importance of Diastolic Blood Pressure

Heart pump’s blood into your blood vessels, enough diastolic pressure requires maintaining blood flow to all parts of your body. Diastolic pressure maintains blood flow back to heart after collecting waste products after consumption of nutrient and oxygen.

Diastolic blood pressure readings are specifically important in the monitoring of the blood pressure in younger individuals.

High and low diastolic blood pressure

If the diastolic number is low, your body cells unable to collect waste products. It may lead to toxin accumulation. If a number less than 60 mmHg are, considering as a low diastolic number called hypotension.

Every 10 mm rise in diastolic pressure may double the risk of heart attack, stroke, kidney failure and heart failure.

At age less than 50 the diastolic is the important predictor of adverse outcome.
