What is the problem in atrial fibrillation?
the top portion of the atria is not squeezing/contracting, which leads to stasis of the blood in the atria
This is the only anti-coagulation drug used in A fib patients with mechanical or artificial valves
**cannot use any of the novel anti-coags
3 novel alternatives to coumadin
Pradaxa is a (blank) inhibitor
Eliquis and xarelto are (blank) inhibitors
What is the CHADSS score used for? What does each component stand for?
used to determine if A fib patients need to be put on a blood thinner;
Congestive heart failure
Stroke (TIA) 2pts

the patient needs to be put on a blood thinner, but not aspirin

What is the difference between clearance of Pradaxa and Eliquis?
Pradaxa is only cleared renally, so it cannot be used in patients with renal failure;
Eliquis is cleared via stool, kidney and liver, so can be used in cases of renal failure
How does a pulmonary embolism present?
mild chest pain
For sudden onset of pulmonary embolism, what drug should be used? Which drugs should not be used? Why?
use IV heparin (not subcutaneous heparin);
do NOT use novel anticoags like pradaxa, eliquis, and xarelto because these meds are active for longer periods of time (12-24 hours) so that once you administer ad dose, you cannot take the patient off the meds to insert a central line or a catheter, etc
