Preinfarction or Crescendo What is unstable angina also known as?
Angina
1) if pain increases
When is angina considered
2) if pain does not respond to a single SL nitro
unstable?
3) pain persists > 5 minutes
What is variant angina also Prinzmetal's angina
known as?
Variant angina results from spasms of the coronary
What is the cause of variant
arteries associated with or without atherosclerotic
angina?
plaque
When does variant angina, also At the same time each day, often at rest
known as prinzm etal's angina ,
usually occur?
What is the treatment for Nitroglycerin or calcium channel blockers
variant angina?
When there is an imbalance between the heart's
When does an MI occur?
demand for oxygen and the supply
, 1) Vasoconstriction
2) Acute blood loss
Other than ACS, what are other 3) Decreased oxygen supply
causes of AMI? 4) Ingestion of cocaine
1) ischemia
2) cellular injury occurs around surrounding cardiac
What are the stages of MI? muscle
3) infarction with necrosis of tissue, cells are
destroyed and replaced with scar tissue
How long does it take for 15-20 minutes
irreversible cardiac damage to
occur with complete occlusion
of coronary arteries?
STEMI is identified by ST segment elevation on EKG
indicating complete blockage of a coronary artery
What is the difference between
STEMI and NSTEMI? NSTEMI does not produce ST segment elevation
and is associated with a partial blockage of a
coronary artery
Q wave MI - pathological, infarction is usually
prolonged and results in necrosis
What is the difference between
a Q and non Q wave MI? Non Q wave MI - characterized by ST segment
depression, usually reversible; reperfusion is
spontaneous
, This type of infarction occurs Anterior wall infarction
with occlusion I'm the proximal
LAD and may damage the let
ventricle
This type of infarction occurs Left lateral wall infarction
with occlusion is the LCX and
often causes damage to the
anterior wall as well
This type of infarction occurs Inferior wall infarction
with occlusion to the RCA and
causes conduction
malfunctions
This type of infarction occurs Right ventricular infarction
with occlusion of the proximal
section of the RCA and
damages the right ventricle
and inferior wall
This type of infarction occurs Posterior wall infarction
with occlusion of the RCA or
LCX and may be difficult to
diagnose
