Determinants Of Arterial Pressure And Contour

Question 1

The pressure wave is dependent on

Answer 1

Compiance of aorta
Velocity of ejection
LV Pump

Question 2

Pulse wave velocity is

Question 3

What is vascular cushioning

Answer 3

Every heart generates a pulse wave which disperses in the human body. Young and healthy vessels are absorbing the energy of the wave-this is called vascular cushioning

Question 4

Arterial ageing

Answer 4

Loss of vascular cushioning by ageing

Question 5

When the pulse velocity is high the risk of cardiovascular event increases to

Answer 5

3-4 times

Question 6

Arterial stiffness reflects

Answer 6

True arterial wall damage
An independent predictive valve ofof CV events
A marker of earlier target organ damage

Question 7

Pulse wave velocity is directly proportional to

Answer 7

Arterial stiffness

Question 8

Gold standard to measure arterial stiffness is

Answer 8

Pluse wave velocity

Question 9

Central systolic bp

Question 10

In a compliant vessel pulse wave is

Answer 10

Slow
Reflected wave returns in diastole (central aorta)
Augmented diastolic pressure
Increases cornary perfusion

Question 11

In a stiff vessel

Answer 11

Pulse wave velocity is high
Reflected wave arrives earlier
Reflected wave will augment the systolic bp
Diastolic bp falls
Cornary perfusion falls

Question 12

As you move from centre to periphery the dicrotic notch becomes

Answer 12

Smooth (becoz fall in peripheral resistance)
Upstroke becomes steeper
No anacrotic notch

Question 13

Radio femoral delay is very crucial in

Answer 13

Coarctation of aorta

Question 14

Time delay to of pulse wave

Answer 14

Radial-80ms
Femoral-75ms
Brachial-60ms
Carotid-30ms
