What is atherosclerosis? - ANSWER a disease in which plaque builds up
inside your arteries. Over time, plaque hardens and narrows your arteries.
This limits the flow of oxygen-rich blood to your organs and other parts of
your body.
What is the pathophysiology of atherosclerosis? - ANSWER 1.Injured
endothelial cells become inflamed and cannot make normal amounts of
antithrombotic and vasodilating cytokines.
2. Inflammatory cytokines are released.
3. Macrophages adhere to injured endothelium through the use of
adhesion molecules.
4. Macrophages then release enzymes and toxic oxygen radicals that create
oxidative stress, oxidize LDL, and further injure the vessel wall.
5. Growth factors are also release, which stimulate smooth muscle cell
proliferation in the affected vessel.
What is an MI? - ANSWER A blockage of blood flow to the heart muscle (heart
attack).
What is the pathophysiology of an MI? - ANSWER -Develops if supply of
coronary blood cannot meet the demand of myocardium for oxygen and
nutrients
-Most common cause of decreased coronary blood flow is
formation of atherosclerotic plaques
-Myocardial cells become ischemic within 10 seconds of coronary occlusion
-Cardiac cells remain viable for approximately 20 minutes under ischemic
conditions. What are clinical manifestations of an MI? - ANSWER • Stable
angina
