The layer of coronary artery most involved by the process of atherosclerosis is:
A. Endothelium
B. intima
C. Internal elastic lamina
D. Media
E. Adventitia
The layer of coronary artery most involved by the process of atherosclerosis is:
A. Endothelium
B. intima
C. Internal elastic lamina
D. Media
E. Adventitia
- Endothelium = top part of intima; want answer for the whole layer! Mid layer of intima is involved by later parts of the atherosclerotic process
The key pathologic process in atherosclerosis is:
A. Monkeburg’s medial calcific sclerosis
B. Cholesterol emobli in the bloodstream
C. Intimal thickening and lipid accumulation
D. Granulomatous inflammation
E. Fibrinoid necrosis of vessel wall

Atherosclerotic plaques consist of the following basic components:
A. Peripheral blood elements and fibrin
B. Granulomata and lipid deposition
C. Amyloid deposits, muscle cells, and fibrinoid necrosis
D. Dysplastic endothelial cells and lipid deposits
E. Smooth muscle cells, inflammatory cells, ECM, and lipid

D. Dysplastic endothelial cells and lipid deposits
E. Smooth muscle cells, inflammatory cells, ECM, and lipid
Typical series of events in atherosclerosis?
- Injury to endothelium
- Smooth muscle migration into intima
- Proliferation of smooth muscle in intima
- Elaboration of ECM in intima
- Lipid accumulartion in intima
- Necrosis
- Calcification
Which is the typical sequence of events in an acute myocardial infarction?
NOT just worsening atherosclerosis with progressive stenosis…that would not be acute MI
- Plaque rupture
- Exposure of subendothelium
- Platelet adhesion and aggregation
- Vasospasm
- Thrombosis
- Occlusion of artery
- Loss of oxygen delivery to myocardium
- Coagulative necrosis of myocytes
Typical microscopic changes seen 24-72 hrs after an MI are:
A. Edema and hemorrhage
B. Coagulative necrosis; loss of nuclei and striations; heavy neutrophilic infiltrate
C. Dark eosinophilic myofibers with stretching and waviness
D. Fibrovascular granulation tissue
E. Extensive phagocytosis of dead cells with collagen deposition

On exam of a heart at autopsy, you find large, irregular masses of the mitral valve leaflets that extend onto the valve cords. You tell the clinician that the most likely etiology of these vegetations is:
A. Infective endocarditis
B. Nonbacterial thrombotic (marantic) endocarditis
C. Acute rheumatic heart disease
D. Endocarditis of SLE (Libman-Sacks Disease)
E. Carcinoid heart disease
