What are the three types of angina? - Correct answer-1. Stable
2. Unstable
3. Prinzmetal's/Variant
What is stable angina? - Correct answer-Excerise induced chest pain relieved by
rest or nitroglycerin (non-emergent)
What is unstable angina? - Correct answer-Chest pain that occurs at rest.
Symptoms more significant (emergent, call 911 right away)
What is Prinzmetal's angina? What is the patient at risk for? - Correct answer-
Spasms of coronary arteries that occur at rest.
High risk for ventricular arrhythmias that can lead to sudden cardiac death
Where is the myocardial oxygen supplied from? What are 2 things that can affect
oxygen supply? - Correct answer-Coronary vessels
1. Blockage (atherosclerosis) & 2. Vasospasm's
,What are 4 things that can affect oxygen demand of the coronary vessels? - Correct
answer-1. HR
2. Preload
3. After-load
4. Contractility
What is the 4 step process for treating classic angina? - Correct answer-1. Nitrates
2. Nitrates & beta blockers
3. Nitrates, beta blockers, & calcium channel blockers
4. Coronary artery bypass graft
What is the 3 step process for treating prinzmetal's angina? - Correct answer-1.
Nitrates OR calcium channel blockers
2. Nitrates & calcium channel blockers
3. Coronary artery bypass graft
Why are beta blockers not given to treat prinzmetals angina? - Correct answer-Can
drop BP which can worsen spasms
,A myocardial infarction is ____ of the myocardial cells, _____ is the most
common cause, and ___ of the heart effects the outcome - Correct answer-1.
Necrosis (irreversible)
2. Atherosclerosis
3. Location
What vessel is responsible for infarctions on the anterior and antero-septal sides of
the heart? - Correct answer-Left anterior descending (LAD)
Highest mortality (widow maker)
Which 2 vessels are responsible for the infarctions on the inferior & posterior sides
of the heart? - Correct answer-Right coronary artery (RCA) or Left circumflex
What vessel is responsible for the infarctions on the lateral side of the heart? -
Correct answer-Left circumflex
What is an transmural infarction? - Correct answer-STEMI
Infraction involving all 3 layers of the heart
What is an subendocardial and subepicardial infarct? - Correct answer-NSTEMI
1. Affecting the endocardium (outer) and partial wall of myocardium
2. Affecting the epicardium (inner) and partial wall of myocardium
, What is the number one atypical symptom of an acute MI? - Correct answer-
Unexplained dyspnea
What is the PQRST assessment stand for? - Correct answer-Precipitation, Quality,
Radiation, Severity, & Time
What is the main purpose of a 12 lead EKG? - Correct answer-Looking at the heart
from different views. The different leads are telling about the different surfaces of
the heart
When would a 18 lead EKG be used? - Correct answer-If a right sided MI is
suspected
Which lead indicates the location of the infarction? - Correct answer-V lead
If there is ST elevation where should the leads be placed? - Correct answer-Over
the area of infraction
If there is no ST elevation or suspected ischemia which 2 leads are used? - Correct
answer-V3 and III ( Double 3's)
If there is ST elevation, what kind of MI is suspected? - Correct answer-STEMI
If there is ST depression, what kind of MI is suspected? - Correct answer-Non-
STEMI
What 3 EKG changes are seen in a STEMI's? - Correct answer-1. ST elevation
