Cards

Term
Acute coronary syndromes umbrella term for
Definition
unstable angina
non-Q wave MI
Q wave MI
ST elevations MI
Non ST elevation MI
Term
how much of vessel must be occluded in order for us to experience symptoms
Definition
75%
Term
What happens when plaque in arteries ruptures
Definition
plaque (calcium build up) ruptures then the body sees this as injury and sends in platelets that stick tother and make clots that cause occlusion.
Term
What is angina pectorals? what causes it
Definition
chest pain caused by myocardial ischemia caused by lack of oxygen to the myocardium. More oxygen demand than supply causing lactic acid build up.
Term
Clinical descriptors of Chest Pain? 7
Definition
substernal epigastric heavy constricting crushing pressure tightness

often associated with nausea or heart burn
Term
Three places chest pain commonly radiates
Definition
jaw
arm
neck
Term
Chest pain is usually associated with
Definition
SOB
Palpitations
Diaphoresis
N/V
Term
what determines where chest pain radiates?
Definition
where the infection is in the heart
Term
Stable Angina
Definition
pt knows they have calcium in coronary vessels, come to ED first time but are sent home with nitroglycerin and advised to stop smoking and drinking and start exercising. means if things don't change there will be problems in future.
Term
Three times when people experience stable angina?
Definition
3 E's exertion, eating, emotional excitement.
Term
what relieves stable angina symptoms?
Definition
rest
nitroglycerin
Term
What is unstable Angina?
Definition
change in previous pattern of angina or new onset of severe angina, usually more intense.
Term
When is severe angina considered a medical emergency
Definition
when it lasts longer than 20 minutes and is not relieved by nitroglycerin
Term
ischemia and injury cause changes is what part of the ECG?
Definition
ST segment.
Term
What does ischemia look like on ECG?
Definition
ST depression (once ischemia goes away then the ST will return to normal on ECG)
Term
what does injury look like on ECG
Definition
elevated ST segment (following injury the st wave will go back to normal and no longer look elevated on ECG)
Term
What does necrosis of myocardium look like on ECG
Definition
Q depression, necrosis causes permanent damamge, once it dies then it will never come back to life, so ECG following heart attack will always show this Q depression.
Term
Non ST Elevation MI (NSTEMI)
Definition
abnormal levels of serum enzymes released but no q wave. this MI has lower in-hospital mortality and complication rates.
Term
NSTEMI pt have increased incidence of what later on ?
Definition
subsequent cardiac events.
Term
what does NSTEMI ECG look like
Definition
no Q wave
ST deviation or T wave changes occur
Term
ST elevation MI (STEMI)
Definition
abnormal levels of cardiac biomarkers
tend to be larger
higher pre-hospital and in hospital mortality
Term
What is STEMI associated with
Definition
more prolonged and complete coronary thrombosis
Term
three ways to diagnosis ACS
Definition
History
ECG
Enzyme Markers
Term
Cardiac Enzyme Markers
Definition
CK-MB
Troponin T/I
Term
Cardiac Enzyme marker: CK-MB (Creatinine kinase, myocardial band).
Where does it occur?
onset?
Peak?
Duration?
Definition
occurs predominately in cardiac muscle
4-8 hours
10-24 hours
48-72 hours
Term
Cardiac Enzyme Marker: Troponin (T/I)
where does it occur
% sensitivity
onset, peak, duration
Definition
occurs in unique structure in cardiac muscle ([art of actin-myocin unit)
100% sensitivity
2-4 hours
24-36 hours
7-14 days
Term
in what order is MONA given
Definition
ONMA
oxygen before morphine because when you come in with chest pain, it is supply and demand, readily available, nitrates next you want to see what happens following nitrate admin. morphine may change action of heart so given next, vasodilation reduces preload, helps with anxiety aspirin is given last because it helps to prevent problems in the future.
Term
Why is Oxygen given with ACS?
Definition
monitor for adequate arterial oxygenation
Term
why is aspirin given with ACS
Definition
anti-platelet effect (NOT ENTERIC COATED)
Term
Why are nitrates given with ACS
Definition
dilates coronary arteries, vasodilator
Term
why is morphine given with ACS
Definition
pain relief, vasodilatior
Term
how much morphine do you admin with ACS
Definition
2-4 mg Q5 Min
Term
Why do you give morphine to some ACS patients
Definition
antithromboitc -prevents further clot formation
Term
what drug do you commonly give to those with NSTEMI
Definition
low molecular weight heparin with NSTEMi
Term
WHy do you give Plavix to ACS patients (ticlid)
Definition
inhibits platelet aggregation
Term
You administer plavix with aspirin in what three situations
Definition
unstable angina
NSTEMI
PTCA
Term
Why do you administer integrilin/Reopro/Aggrastat with ACS
Definition
antiplatelet
Term
When do you give calcium channel blockers with ACS
Definition
if vasospams
Term
What patients is it important to give ACE inhibitors with ACS
Definition
Those at risk for heart failure
Term
when do you give ACE inhibitors with ACS
Definition
1st 12-14 hours
Term
Three effects of beta blocks with ACS
Definition
decreases O2 demand
decreases heart rate
decreases BP

(will decreases intact size)
Term
when do you give beta blockers following ACS
Definition
intravenously within first few hours.
Term
How long is forgiveness of heart muscle
Definition
12 hours
Term
two indications for fibrinolytic therapy (therapy to break up big clots)
Definition
chest pain for less than 12 hours
st segment elevation of at least 0.1mv in at least 2 continuous leads
Term
Three repercussion therapies
Definition
fibrinolytic therapy
percutaneous coronary intervention (PCI)

Term
balloon angioplasty
Definition
catheter with balloon at distal end placed into after with plaque buildup, balloon inflated to open up plaque, stent added at this site.
Term
Atherectomy
Definition
excision and removal of atherosclerotic plaque by cutting shaving or grinding.
Term

Definition
expandable stent placed in coronary artery to prevent restenosis, requires antiplatelet therapy post procedure because you are putting metal into the vessel,
Term
