w/in 12 hrs
When should you NEVER use tPA?
head injury
bleeding (internal)
stroke
surgery

lef sided CHF
What is left sided CHF?
fluid backs up into the lungs
What is the biggest cx of CHF?
HTN
What is the pathophys behind CHF?
CO is too low –> renin-angiotensin-aldosterone is activated –> increase in preload
What are 2 types of CHF?
systolic - problem squeezing
diastolic - problem filling
What is happening in systolic CHF?
cardiomyopathy - too big and won’t squeeze effectively
Pt has orthopnea and paroxysmal nocturnal dyspnea and diaphoresis -what to expect on PE?
dullness on percussion rales S3 gallop displaced PMI rales
What is happening in diastolic CHF?
myocardial hypertrophy - too much muscle and will not fill all the way but squeezing is fine
What are the NYAH classifications?
I - only w/ aggressive activity
II - climbing stairs; little limitation
III - daily activities are affected; mod limitation
IV - sx at rest; BAD
Pt has pitting edema, JVD, ascities?
right sided CHF
What test/labs to order for CHF?
CXR EKG cardiac enzymes - r/o MI CBC - r/o anemia (can cx CHF) echocardiogram - first line and gold standard bnp
What to see on CXR - CHF?
cardiomegaly
Kerle B lines
Tx for CHF-systolic?
mild/I-II -first line: ACE-I \+/-diuretic mod/II-III -ACE-I + diuretic + Beta blocker severe/III-IV -ACE-I + diuretic + Beta blocker + digoxin
Discharge drugs for CHF systolic?
ACE-I
beta-blockers
What to use if pt cannot use ACE-I?
ARB
What drugs are CONTRAINDICATED in CHF pts?
metformin
NSAIDs
Tx for diastolic CHF?
lifestyle changes beta-blockers diuretics digoxin \+/-ACE-I
Pt comes in with S3 + S4, dyspnea, pitting edema?
dilated cardiomyopathy
Cx of cardiomyoptahy?
idiopathic

echocardiogram - gold standard - dilated chamber
How to tx dilated cardiomyopathy?
admit + nitrate + O2 + B blockers + diuretics + ACE-I/ARB

Pt suddenly drops dead - literally?
dilated cardiomyopathy
most likely hypertrophic cardiomyopathy
Is hypertrophic cardiomyopathy genetic?
yes - autosomal dominant
YOUNG pt has chest pain on exertion, syncope, and palpitations?
hypertrophic cardiomyopathy
What is the pathophys of hypertrophic cardiomyopathy?
diastolic problem - overworks during exercise causing increase in HR + contractility
