Why Does Hypertension Cause Vasoconstriction?

Vasoconstriction and blood pressure
Vasoconstriction reduces the volume or space inside affected blood vessels. When blood vessel volume is lowered, blood flow is also reduced. At the same time, the resistance or force of blood flow is raised. This causes higher blood pressure.

How does hypertension affect blood vessels?

Hypertension gradually increases the pressure of blood flowing through your arteries. As a result, you might have: Damaged and narrowed arteries. High blood pressure can damage the cells of your arteries' inner lining.

Is hypertension a vasoconstriction?

In hypertension, systemic vasoconstriction (increase of systemic vascular resistance) is typically the primary event in the genesis of hypertension, so that mean arterial pressure is increased, whereas cardiac index is generally normal or slightly decreased.
