Q

Your pt has suspected CAD pt has a history of prior GI bleed. Can you prescribe both Atorvastatin 10mg QD before bedtime and Aspirin 81 mg QD?

A

You can give Atorvastatin but not Aspirin

-prior GI bleed is a contraindication.

Q

What is occlusive atherosclerotic lesions that develop in the legs, and sometimes, in the arms causing decreased perfusion of the extremities

A

Atherosclerotic Peripheral Vascular Disease (PAD)

18
Q

PAD are symptoms of what process?

A

systemic atherosclerosis process

19
Q

PAD can be diffuse but usually occurs segmentally. What are some examples of where it can developAorto-Iliac segments

A

Aorto-Iliac segments
Femoral- Popliteal segments
Tibial segment

20
Q

PAD is a high correlation in smokers and patients with ______

A

Diabetes

21
Q

A patient with some of these symptoms might suggest what type of Atherosclerotic Disease?

(a) Claudication: Cramping pain or tiredness in the thigh, calf, or foot with walking or exercise and relieved by rest.
(b) Diminished femoral, popliteal, or pedal pulses.
(c) Tissue ulceration and gangrene.
(d) Erectile dysfunction
(e) Loss of hair
(f) Thinning and cool skin
(g) Atrophy of muscles

A

Atherosclerotic Peripheral Vascular Disease (PAD)

22
Q

Your PAD pt has cramping pain and tiredness in the leg that is not relieved by rest. What may they be at risk for?

A

amputation

23
Q

What could be some differential diagnoses for PAD?

A

(a) DVT
(b) Muscle strain or cramp
(c) Neuropathy

24
Q

What are the labs/ imaging you would consider for your PAD pt?

A

(a) Doppler examination with ABI
(b) CT Angiography and Magnetic Resonance Angiography if intervention is required.
(c) Lipid panel
(d) Chemistry - to evaluate for renal dysfunction

25
Q

What are some NON-pharmacological tx for PAD

A

26
Q

What is a pharmacological tx for PAD that you may see your patients taking?

A

Phosphodiesterase inhibitor
Cilostazol
.

27
Q

what medication has this MOA; what is it used to treat?

Inhibits phosphodiesterase type 3, reducing platelet aggregation, produces vasodilation

A

Phosphodiesterase inhibitor

Treatment of PAD

28
Q

_______are thrombus or plaque that breaks off and travels until the lumen becomes too small for the emboli to continue to move

A

Emboli

29
Q

is a blood clot that forms as a plaque ruptures and platelets start to adhere and aggregate on the rupture site.

A

Thrombus
