🫀ARTERIAL HYPERTENSION:
VASCULAR REMODELING AND LOSS OF ELASTICITY

High blood pressure does not first “clog” the artery — it remodels the vessel.

CONCEPT

Chronic arterial hypertension = sustained increase in the force of blood against the vessel wall

Arteries (elastic structures) adapt to hemodynamic overload

PATHOPHYSIOLOGICAL MECHANISM

Continuous mechanical stress → endothelial injury (inner layer of the vessel)

Endothelial dysfunction → reduced vasodilator nitric oxide

Vascular smooth muscle proliferation + collagen deposition

Result:
• Thickening of the arterial wall
• Reduced compliance (elasticity)
• Increased vascular stiffness

KEY PROCESS

Vascular remodeling
Progressive structural adaptation of the artery to elevated pressure

HEMODYNAMIC IMPACT

Rigid artery → reduced ability to expand

→ Increased peripheral resistance
→ Cardiac overload (especially left ventricle)

SILENT PROGRESSION

Slow and asymptomatic process

By the time symptoms appear, damage may already be significant

ASSOCIATED COMPLICATIONS
• Coronary artery disease
• Stroke (CVA)
• Heart failure
• Chronic kidney disease

CLINICAL INSIGHT

Hypertension does not begin as “blockage” — it begins as loss of vascular function

Regular blood pressure monitoring is essential

✅Early intervention = prevention of irreversible structural damage
