A
local - aneurism
system - ischemic heart disease, cerebral vascular disease, peripheral vascular
2
Q
what is pre-athero sign
A
fatty streaks
3
Q
what is seen next
A
lesions that begin to coalesce
4
Q
what can happen next
A
thrombus, erosion
5
Q
what is cholest. crystal
A
embolism that breaks off and can travel in vessel
6
Q
what happens in unstable athero
A
- thinned epithelium
- fibrous cap rupture
- blood gets in and makes thrombus
7
Q
what happens in adaptation stage
A
- small break in endothelium
- macrophages enter
- macros eat lipis and become lipid laden (foam cells)
- SMC enter and proliferate in the intima
8
Q
7 steps in clinical stage
A
- mural thrombus
- embolization
- plaque hemorrage
- plaque rupture
- aneurysm
- stenosis
- thrombisis
9
Q
3 active areas of athero research
A
- inflammation in the plaque
- cause of plaque rupture
- inducing plaque regression
