Arteriosclerosis

Question 1

Arteriosclerosis

Answer 1

hardening of the arterioles

- less compliant, less elastic, higher blood pressure

Question 2

Hyaline arterioslcerosis

Answer 2

1. high bp causes proteins in blood to enter blood vessel wall
2. walls become lined with proteins
3. walls are stiffer and thicker
4. Narrow lumen
5. Blood flow is reduced to organ

Question 3

Hyperplastic arteriosclerosis

Answer 3

1. Hardening of blood vessels due to high bp
2. blood vessels compensate by adding more layers of smooth muscle
3. Reduces diameter of lumen

Question 4

Monckberg medial sclerosis

Answer 4

1. Calcium deposits are found in muscular layer
2. Hardening of blood vessel
3. Diameter is not affected
4. Blood outflow is not affected - mainly asymptomatic

Question 5

Clinical presentation of ateriosclerosis

Answer 5

1. Kidneys
   • Arterionephrosclerosis -> Chronic renal failure
   • lack of blood supply to glomerulus causes it to scar
2. Chest pain and angina
3. Leg pain
4. Stroke like symptoms

Question 6

Diagnosis of arteriosclerosis

Answer 6

• Weakened pulse
