Robbins Vessels Flashcards
- Thinning of the media not necessarily associated with
acute coronary syndrome
- Something like AAA can be closely associated with
poorly controlled diabetes mellitus (strongest risk factor listed here)
- Thrombophlebitis a common problem resulting from
venous stasis (compared to varicose veins that are superficial and can thrombose, BUT NOT RELATED TO BED REST)
- Key components of essential HTN
Renal retention of excess Na:
- increased intravascular fluid volume
- increase in CO
- peripheral vasoconstriction
- Venous stasis results in
hemosiderin deposition and dermal fibrosis, with brownish discoloration and skin roughening (can see some focal ulceration and only the superficial set of veins involved in this case)
- Deletion of what can help with atherosclerosis?
T-cell receptor genes: lose these, prevent T cell development and T cells cannot adhere to VCAM-1 on activated endothelial cells to migrate into vessel wall. They can then secrete various proinflamm molecules to recruit and activate monocytes and smooth muscle cells and perpetuate chronic inflamm of the vessel wall
- If a premenopausal woman or a young man has severe coronary atherosclerosis,
diabetes must be suspected as a predisposing factor (softer risk factors are obesity, stress, lack of physical activity/exercise)
- Skin lesions in upper chest with central pulsatile cores are
spider telangiectasias, a consequence of micronodular cirrhosis, typically as a consequence of chronic alcoholism; think of hyperestrogenism that results from hepatic damage
- Angiosarcoma can appear as
an irregular, infiltrative, soft reddish mass, with pleomorphic spindle cells positive for CD31;
look for POLYVINYL CHLORIDE association!!!
- CRP is an acute phase reactant that
increases in response to inflamm; causes endothelial cell activation, promotes thrombosis, and increases leukocyte adhesiveness in developing atheromas;
it is an independent predictor of cardiovascular risk
