How do atherosclerotic plaques affect blood flow at rest and exercise?
Not much at rest, as there’s reserve capacity. But significantly during exercise as vessels cannot dilate
If there’s pain in buttock or hip, where is the peripheral artery disease?
Aorta-iliac
If there’s pain in the thigh, where is the peripheral artery disease?
Aorta-iliac or common femoral artery
If there’s pain in the upper 2/3 of the calf, where is the peripheral artery disease?

How do you manage intermittent claudication?
Exercise programme
Angioplasty or bypass
What technique is used to inject fluid to perform invasive CA?
Seldinger
What is the downside of angiograms?
You cannot see the heart wall
- Pathology can occur in the wall
- Imaging doesn’t show the default arterial state: the artery may seem narrowed but this might be physiological
What is class I angina?
Angina only present with strenuous exertion
What is class II angina?
Angina with moderate exertion
What is class III angina?
