SIHD TEST QUESTIONS AND
ANSWERS 2024-2025
Cause of SIHD
caused by an obstructive atherosclerotic plaque in one or more
epicardial coronary arteries
Increases in myocardial oxygen demand in the setting of a fixed
decrease in myocardial oxygen supply result in myocardial ischemia
cardinal symptoms of myocardial ischemia in patients with SIHD
Chest pain (angina)
What meds play an important role in preventing CVD events in
patients with SIHD?
1. aspirin
2. ACE-I
3. Statins
First line therapy in controlling number of episodes of angina?
Beta-blocker
First line therapies in vaspospactice disease?
CCB and nitrates
often used additional therapies in SIHD?
1. CCB
2. Long-acting nitrates
3. ranolazine
all patients with SIHD should receive what?
SL NTG
option in severe atherosclerotic disease?
revascularizatoin followed by antithrombotic therapy
ACS includes
unstable angina, NSTEMI, STEMI
, ACS plaques?
unstable
rupture and lead to clot formation
Prinzmetal's angina (variant)
Caused by vasospasm of a coronary artery
plaques in SIHD?
1. stable
2. reduce lipid core
3. firm calcified covering
MVO2 determinants? leading one?
1. HR
2. heart contractility
3. intramyocardial wall tension
3 is leading factor
what supplies the heart with oxygen?
coronary arteries
non-obstructive plaques?
take up 50-50% of the vessel luminal diameter
When is a plaque obstructive?
covers 70% or more of luminal diameter
How does SL NTG help?
increasing myocardial oxygen supply through vasodilation of
epicardial vessels and a reduction in preload.
duration of chest pain in SIHD?
less than 20 minutes
major differences between ACS and SIHD?
duration
precipitating factors
CCS class 1
