Coronary Artery Disease Flashcards
“pain in the anterior chest”
angina
what are s/s of CAD
angina
dyspnea
nausea
weakness
what are causes of angina
⬇️ blood flow = ⬇️ O2 supply at times of high demand
type of angina:
predictable & consistent pain that occurs on exertion
stable
type of angina:
is relieved by rest or nitroglycerin
stable
type of angina:
symptoms ⬆️ in frequency in severity; may not be relieved by rest or nitro
unstable
type of angina:
severe incapacitating chest pain
intractable/refractory
type of angina:
pain at rest w/ reversible ST segment elevation
variant
type of angina:
caused by coronary artery vasospasm
variant
type of angina:
pt has no pain but there is evidence of ischemia via stress test
silent ischemia
an area of myocardium is permanantly destroyed
MI
what are causes of an MI
vasospasm of coronary artery
imbalance in O2 supply & demand
artery occlusion
EKG:
s/s of coronary ischemia but ekg & biomarkers show no evidence of MI
unstable angina
EKG:
evidence of acute MI w/ characteristic changes in 2 ekg leads; significant myocardial damage
STEMI
EKG:
⬆️ biomarkers but no ekg evidence of acute MI
NSTEMI
