aortic atheroma
Pathology:
- intimal thickening
- calcification may actually confer stability to atheroma
- sometimes ulceration, destablization, development of mobile projections & embolization
Special laboratory:
- transesophageal echocardiogram
Complications:
1) aortic atheromas >= 4 mm in thickness in the ascending aorta or aortic arch increase the risk of recurrent embolic stroke
2) atheromas in the descending aorta are markers of atherosclerosis & cardiovascular risk, but do not seem to be associated with pathologic embolism
Management:
1) life style modification, risk factor reduction*
a) smoking cessation
b) heart-healthy diet
c) aerobic exercise
2) antiplatelet agent: aspirin or clopidogrel
- warfarin may be superior to aspirin for prevention of stroke
3) statin
* MKSAP dismisses diet & lifetyle modification; advocates aggressive treatment with anti-platelet agent & statin [1]
