Does the AAFP recommend dual therapy with anticoagulants and antiplatelet therapy in patients with afib?

A

no

21
Q

what situations may call for dual therapy with anticoagulants and antiplatelet?

immediately after a stent

22

0-9

23
Q

HAS-BLED examines bleeding risk for which problems?

A

24
Q

HAS-BLED is validated only for which medication?

A

warfarin

25
Q

INR >3 but < 4.5 interventions

A

decrease or hold dose then lower dose once INR is within normal limits

26
Q

INR 4.5 to 10 interventions

A

hold next one or two doses then lower dose once INR is within normal limits-NO VITAMIN K

27
Q

INR >10 interventions

A

administer vit K (2.5 to 5 mg po per dose)

28
Q

Stroke risk factors

A

HTN, Diabetes, hyperlipidemia, Obesity, Sleep apnea, Smoking, Alcohol, lack of regular activity

29
Q

virchows triad

A

3 categories of factors that are thought to contribute to thrombosis (Endothelial damage, Blood flow stasis, hypercoagulation)

30
Q

what does the wells prediction rule help to diagnose?

A

predictor for diagnosing DVT or PE

31
Q

wells prediction rule takes what into consideration for DVT?

A

active cancer, paralysis, recently bedridden, localized tenderness, leg swollen, calf swelling, pitting edema, collateral superficial veins (nonvaricose)

32
Q

what kinds of DVTs are more dangerous than distal DVTS that are formed below the popliteal trifurcation in the veins of the calf?

A

Proximal DVTS that develop above the popliteal trifurcation in the popliteal and femoral veins of the thigh

33
Q

AMUSE score

A

can help the provider decide if an ultrasound is needed

34
Q

AMUSE score of <3

A

probs not a DVT, no ultrasound needed

35
Q

AMUSE score of >4

A

probably a DVT, do ultrasound

36
Q

AMUSE score takes what into consideration?

male sex, malignancy in last 6 months, had surgery within 1 month, absence of leg trauma, hormonal contraceptives, collateral leg vein distention, discrepancy of >3 cm in calf circum, elevated D-dimer

37
Q

what is the treatment recommendation for PE or proximal DVT, what if they also have cancer?

A

anticoagulant therapy for 3 months, if they have cancer, heparin is needed

38
