17. pathogenesis
4 main stages :

2. Accumulation of lipoproteins
3. Resultant Inflammation & Factor release
4. Smooth muscle cell recruitment, proliferation and ECM production.

19. Chronic endothelial injury
increased endothelial
permeability
enhanced leukocyte
(monocyte and T lymphocyte )
and platelet adhesion
Monocyte migration
