SIHD Exam Questions with 100% Correct
Answers 2024/2025
What characterizes ischemic heart disease? - ANSWERSreduced blood supply to the heart muscle,
usually due to coronary artery disease (CAD)
What are two disease states that are under ischemic heart disease umbrella? - ANSWERS1) chronic
stable Angina (CSA)
2) Acute Coronary syndrome (ACS)
What happens in chronic stable angina? - ANSWERSVasospastic; where small blood vessels near the
surface of the skin have spasms that limit blood flow.
What happens in Acute Coronary Syndrome (ACS) - ANSWERSMI and unstable angina
What are coronary arteries in the heart? - ANSWERSRight coronary artery
posterior descending branch
left main
Left circumflex artery
left anterior descending artery
Which artery bring oxygen and blood to the heart? - ANSWERSRight coronary artery
Atherosclerosis is when plaque builds up and obstruct blood flow in the epicardial vessel, which
consequently does what to the vessels? - ANSWERS- decreases the lumen size
- increses resistance in the epicardial vessels
During Myocardial Oxygen Consumption (MVO2) (like excerise) your HR increases and so does BP. this
causes greater degrees of obstruction and when a patient has atherosclerosis they can't meet that
, oxygen demand, why? - ANSWERSThe arterioles can't dilate anymore, therefore they lose that
autoregulation that the body does to meet oxygen demands.
Why do anginal attacks occur? - ANSWERSoxygen demand increases and the body can't meet those
oxygen demand because they have a fixed O2 supply
what is the normal physiology of myocardial oxygen supply? - ANSWERS- arterial O2 content
- o2 becomes saturated
- O2 exctraction occurs
- Then the O2 flows to the coronary arteries
- lumen area is affected in diameter
- Vasomotor tone
- Diastole happens
- Vasospasm (systolic)
What factors are contributed in the myocardial oxygen demand? - ANSWERS- Heart rate
- Contractlity
- Myocardial wall tension (DIRECTLY related to the size of the ventricular cavity and BP, and INDIRECTLY
related to muscle mass)
Now we talking about one of the topics under Ischemic heart disease and that is chronic stable angina -
ANSWERS
What is angina pectoris? AKA as just angina - ANSWERSchest pain most often caused by myocardial
anoxia as a result of occlusion of the coronary arteries from either atherosclerosis or spasm
What is chronic stable angina? - ANSWERSPREDICTABLE AND REPRODUCIBLE left anterior chest
discomfort after physical activity, emotional stress or both
what are the clinical features of chronic stable angina? - ANSWERS- reversibility of symptoms
- repetitiveness of anginal attacks
