DPT-772: MI AND HF LECTURE EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED
What is an atheroma?
A fatty layer of an artery
Atherosclerosis is one of the
primary causes of a heart attack
Definition of atherosclerosis
The disease of the arteries characterized by the deposition of plaque of fatty matter on
the inner walls of our coronaries and our arteries
What is early atherosclerosis
Streaks of fatty tissue being deposited on the inner lining of the coronary artery
What is advanced atherosclerosis (3)?
Growth of fatty layers (atheroma) that start to block the artery channel
What is advanced atherosclerosis (4)?
Deposit of hardened fibers into plaques with increased blockage of the artery?
High blood pressure can
Increase the risk of rupture of the plaques and then clot formation which continues to
close the lumen
What is severe atherosclerosis (5)?
Ruptured plaque with formation of clot and partial blockage of channel
What is severe atherosclerosis (6)?
, Clot grows and totally block the artery, completely cutting off blood flow?
Atherosclerosis is not selective in the sense that
it can occur in specific arteries --> it affects all the arteries
CVD
Cerebrovascular disease which is atherosclerosis in the arteries going to and in the
heart (leads to TIA or CVA)
PAD
Peripheral arterial disease which is atherosclerosis in the arteries going to the
extremities (leads to IC and necrosis)
CAD
Coronary artery disease which is atherosclerosis in the arteries of the heart (leads to
angina and MI)
Heart attack definition
A temporary decrease in blood supply causes the cardiac muscle to become ischemic
and produces chest pain (angina)
What cause myocardial infarction?
A prolonged and total loss of blood supply leading to irreversible muscle damage
No damage is done if
The demands of the heart are decreased (decreasing activity, decreasing HR or BP) or
the perfusion is improved
What medication is commonly prescribed for patients following heart attack?
What is it's function?
