Coronary Artery Disease (CAD)

Question 1

coronary artery disease (CAD)

Answer 1

• NOT restricted to coronary artery (means coronary circuit)
• one or more branches of coronary circuit has advanced atherosclerosis –> can’t provide blood to heart cells (ischemia) –> l/o heart Fx

Question 2

types

Answer 2

• chronic ischemic heart disease

- acute coronary syndromes (ACS)

Question 3

chronic ischemic heart disease

Answer 3

• chronic

- ischemic = blood still coming in, but not enough for O2 demand

Question 4

results of chronic ischemic heart disease

Answer 4

• stable angina
• variant angina
• silent myocardial ischemia (asymptomatic; ischemia in coronary circuit)
• microvascular angina (exercise-induced; angiogram looks normal –> hard to Dx)

Question 5

acute coronary syndromes (ACS)

Answer 5

• unstable angina

- myocardial infarction

Question 6

progression of ACS

Answer 6

• unstable angina (plaque disruption & platelet aggregation)
• non-ST-segment elevation MI
• ST-segment elevation MI
