Cardio 1 Flashcards
Artery most affected in MI? What is EKG Findings?
Part of heart affected?
LAD V2, 3 and 4
Anterior heart and septum (V1 V2 V3)
Circumflex artery MI has changes in what?
Lateral leads. I, aVL and V5 and V6
RCA goes to PDA (in right dominant heart 70% of people). Infarct of that shows what EKG finding?
Inferior wall. II, III and aVF
PDA can come off of what?
10% is off circumflex, 20% is codominant
A C and V wave?
Atrial kick. triCuspid closing and V is right before systoly
Fick principle?
CO=SVXHR
CO= rate O2 use/Arterial O2-Venous O2
Rate O2 use is comparing O2 inhaled to exhaled
exercise increase output how?
first is SV is up, then increased heart rate
MAP is what? KNOW BOTH EQUATIONS!
MAP=CO X TPR
= 2/3 diastole + 1/3 systole
PR interval greater than normal is what?
Type 1 block
Greater than .2 seconds
U wave is what?
Visible with hypokalemia
Do stress test when patient is symptomatic
What is a positive test?
No need to do it before symptomatic
When ST depression
Follow up for ST changes or angina in exercise stress test?
Coronary agniogram
Bipolar patient on mood stabilizer has depression. What do you add?
Atypical antipsychotic
Screening of lipids starts wheN?
Men 35, women 45
Statins for who?
Clinical cardiovascular issue means high or moderate statins
(risuvostatin or atorvostatin)
LDL >190
DM age 40-75 need low to moderate UNLESS 10 year risk is 7.5% or higher then need high intensity
Statin 2 side effects? What do you order?
hepatotoxic and muscle injury
Order ck if muscle pain. No need to routine lft checks
Ezetimibe mechanism and side effect?
Brush border inhibition, so not absorbed. Myalgia and LFTs
Lowers LDL. Used if statins not tolerated
Fibrates does what?
Lowers triglycerides
Risk of pancreatitis. They reduce VLDL
Myositis and LFT elevation
VERY CAREFUL WHEN MIXING WITHS TATIN
Bile acid resins are what and do what?
Reduce LDL and are colestipol, colesevelam, cholestyramine…
GI SIDE EFFECTS BIG TIME!!!
Cholestyramine can bind C diff toxin
Niacin does what? Side effect? How do you reduce it?
Raises HDL
Side effect of flushing!!!! Reduce with NSAID
Best affect on Triglyceride?
Fibrates (REMEMBER CAREFUL WITH STATINS)
What do you check before statins?
LFTs
