CARDIAC Flashcards
Coronary Arteries
deliver oxygenated blood to the heart; encapule around the heart; arteries that provide the heart blood
- give the heart its blood supply
Risk Factors of CAD
High Cholesterol
Smoking
Alcohol
Diabetes
Diet
No exercise
-start by educating patients about the risk factors
Atherosclerotic Plaque
artery is narrowed d/t plaque —> ISCHEMIA
when sites of the heart die off and aren’t getting any 02 or blood supply from the infarcted vessel it will die off
MI occurs 24-48 hours after
potassium starts to leak out and cause
V-FIB
now working 24-48 hours to make sure no complications of v-fib or rupture
Cardiomyocites have potassium in them–>die off the heart–> leads to ischemia
how do we treat hyperlipidemia?
statins
( Simvastatin, atorvastatin, suvastatin)
what will statins do? and ranges?
Will decrease our total cholesterol 200
Decrease Triglycerides 150
Decrease LDL 100
Increase HDL 50
if a patients cholesterol went from 380-340 but normally its 200, is medication working?
YES; it dropped.
when do we give statins?
AT BEDTIME
- thats when we go into a fasting state
when we’re in a fasting state we release cholesterol; its the perfect time to attack them.
prior to administering the drug what are we going to check?
LIVER FUNCTION TESTS
ALT
AST
ALK
side effect of ‘STATINs
MYOPATHY
muscle pathology; specific myopathy we’re concerned about it
RHABDOMYOLYSIS (rhabdomeres of muscle is breaking down)
— muscle is made of protein: protein is going to get dispersed, excreted and cloggs glomeruli– will develop ACUTE KIDNYE INJURY
- if we don’t aggresively hydrate with IV fluids: will lead to ACUTE RENAL FAILURE
they’re going to come in with muscle pain, muscle weakness, tenderness
red flag for ‘STATIN
- check kidney function (BUN/CREATININE)
- LIVER TESTS
A clogged artery will cause
Chest Pain, developing ANGINA
2 types of angina
- STABLE ANGINA
- UNSTABLE ANGINA
