Exam 2 - high yield Flashcards
Tx for stable CAD?
A=ASA, ACEI/ARB B=Beta blocker (Metoprolol) C=Cholesterol and Cigarettes D= Diet E=Exercise
PAD treatments? (Hint: Three)
- ASA
- Clopidogrel if ASA allergy
- Cilastazol w/IC
VTE prophylaxis in gen med PT and if trauma patient? Dose? Renal?
Gen med:
- UHF 5000U SC (good for renal)
- Enox 40mg SC or 30mg SC if Cr below 30
- Fonda 2.5mg SC or not if Cr less than 30.
Trauma: Enox
Fondapirinux dose for DVT prophylaxis and VTE tx? Renal concerns?
DVT Proph: 2.5mg SC daily. If CrCl less than 30 don’t give.
VTE: 5-10mg daily SC between 50kg and 100kg.
Enoxaparin dose for DVT prophylaxis and VTE Tx? Renal concerns?
DVT Proph: 40mg SC. CrCl less than 30 then 30mg.
VTE Tx: 1mg/1kg q12h SC -or- 1.5mg/kg q24h
Tx of Acute VTE? If bad kidney? Goal?
- Enoxaparin 1mg/kg. (Best, CrCl 20 no)
- Fondapirinux 5mg to 10mg. (CrCl 20 no)
- UFH.
Bad kidney=UFH.
Goal=transition to PO Warfarin with INR of 2-3.
Tx for VTE if kidney good? If kidney bad? Duration? INR goal?
Good kidney=LMWH daily or q12h (Enox 1mg/kg or Fonda 5-10mg)
Bad kidney= IV UFH x5 days
1st occurrence= Warfarin x3 months
2nd occurrence= Warfarin lifelong
INR=2-3 (2.5 ideal)
In Acute VTE which medication to use if renal impairment is an issue?
If CrCl less than 20 do not use LWMH (Enox or Fonda)! Use UFH to reduce bleeding
Tx of choice for Pulmonary Embolism? Shock with low bleed risk? Small PE?
Acute PE=5-10mg Fondaparinux or 1mg/kg Enodaparin
or IV UFH
Shock with low bleed risk= Thrombolytic
Small PE= Alteplase
Tx for high-risk PE? Renal impairment? High risk bleeding?
IV UFH is agent of choice.
High -risk bleeding=Apixaban (less bleeding)
Renal impairment= Warfarin is gold standard and then Apixiban
AFib/AFlutter stroke prevention? (Hint: three)
- Warfarin 5mg if healthy, 2.5 older than 75 or hepatic dysfunc
- Dabigitran
- Oral Xa
Tx for Secondary Stroke Prevention if from cardioembolic stroke (Afib/Aflut)? INR?
Warfarin aka Coumadin. INR 2-3.
Tx for NSTEMI? What if going for PCI?
Morphine Oxygen Nitrates ASA Heparin Beta-Blocker PCI=Prasugruel (P2Y12-inhib)
What is reversal agent for Indirect Thrombin Inhibitors (LMWH and UFH/Enox)?
Protamine Sulfate IV.
UFH= 1mg:100U
Enox=1mg:1mg 60-70% effective
None for Fonda.
Tx for Acute Ischemic Stroke? When to use what? What are two major exclusion criteria?
- IV t-PA within 4.5hr
- ASA 325mg PO 12-24h after t-PA
Exclusion: SBP 185 or DBP 100, 80+
Secondary stroke prevention if not from cardioembolic? (Hint: 3)
- ASA
- ASA + Dipyridamole ER
- Clopidogrel if cannot tolerate ASA
What are the 4 main anti-platelets? MOAs?
- ASA (COX-inhib)
- Clopidogrel (ADP P2Y12-inhib)
- Cilostazol (PDE-inhib)
- Dipyridamole (Adenosine + PDE-inhibitor)
(ACCD)
What are the indications for the 4 main anti-platelets?
- ASA=PAD, CVA/TIA prevention and treatment
- Clopidogrel=PAD
- Cilostazol=PAD with intermittent claudication
- Dipyridamole=Secondary CVA/TIA prevention
What is intermittent claudication? What is it a sign of?
Cramping in legs. Sign of PAD.
What is the class and mechanism of ASA? Side-effects? Contraindications?
Class: Antiplatelet
MOA: Irreversibly inhibits prostaglandin cyclooxygenase (COX-1) in platelets. Prevents formation of Thromboxane A2 (TXA2).
SE: GI upset and/or bleeding
Contras: Active bleeding, hemophilia, thrombocytopenia
What is the class and mechanism of Dipyridamole? Side-effects? Contraindications?
Class: Antiplatelet
MOA: Inhibits platelet aggregation via adenosine and PDE inhibition.
SE: Angina, HA, dizziness, hypotension, dyspnea
Contras: Active bleeding, CAD (“coronary steal syndrome”)
What is the class and mechanism of Cilostazol? Side-effects? Contraindications?
Class: Anti-platelet
MOA: Phosphodiesterase inhibitor; suppresses platelet aggregation; direct artery vasodilator
SE: Fever, infection, tachycardia
Contras: All CHF patients. They’ll die quicker.
