Acute Coronary Syndromes Flashcards
TIMI Risk Calculation
- predicts risk of death or MI in the next 14 days
- risk varies from 5-41%
What are the 3 goals of therapy for unstable angina/NSTEMI?
- diminish coagulability
- relieve pain
- decrease workload of the heart
What meds are used to diminish coagulability in UA/NSTEMI pts?
- anti platelets: ASA, P2Y12, IIbIIIa inhibitors
- anti coagulants: heparinoids, bivalrudin
What meds are used to relieve pain in UA/NSTEMI pts?
- SL and IV nitro
- morphine
- BB
What meds are used to decrease the workload of the heart in UA/NSTEMI pts?
BB
UA/NSTEMI Aspirin Therapy
-162-325 mg unless CI or already taken
What are the P2Y12 Inhibitors and what are they used for?
- clopidogrel (Plavix)
- ticagrelor (Brilinta)
- prasugrel (Effient)
- used to diminish coagulability (anti platelet agents)
Who should receive a high dose clopidogrel regimen? What is considered a “high dose?”
- 300 mg vs 600 mg load
- hx MI, stent placement, ACS, DM
In what patients should prasugrel be avoided?
- hx of TIA or stroke
- 75 y.o
- undergoing surgical procedure (CABG)
- CrCl < 60 mL/min
- warfarin pts
Prasugrel should be used in what types of pts?
-in high risk MI patients (DM or hx of MI) getting PCI
When should IIaIIIb inhibitors be used before PCI?
- DM or STEMI or elevated troponins and low bleed risk
- recurrent pain on ASA, P2Y12, and heparin
What is the dosing of sublingual nitro?
-0.4 mg SL q5 minutes for 3 doses
When is IV nitro contraindicated?
- hypotension (SBP < 100)
- tachycardia > 100 bpm
- phosphodiesterase inhibitor within 24-48 hrs
When is IV morphine sulfate indicated?
-uncontrolled chest pain despite IV NTG
When is IV morphine sulfate contraindicated?
- hypotension SBP < 100
- tachycardia > 100 bpm
What is the indication for oral beta blockers?
First 24 hours for all patients who do not have:
- signs of active HF
- evidence of low output state/cardiogenic shock
- PR interval greater than 0.24 seconds
- 2nd or 3rd degree heart block
- active asthma
Signs and Sxs of Uncompensated Heart Failure
- orthopnea
- PND
- DOE
- ascites
- 2-3+ pitting edema
What patients should receive oral ACE-I/ARBs?
in first 24 hrs to pts w/ pulmonary congestion or LVEF < 40% unless contraindicated
What are the CIs for ACE-I/ARBs?
- hypotension (SBP < 100)
- BL renal artery stenosis
- hx angioedema
- 2 or 3 trimester pregnancy
What are the goals of therapy for treating STEMI?
- relieve pain
- re-perfuse
- diminish coagulability
When are lytics used?
- given if the 90 minute PCI window is not met
- most effective within 12 hours of symptom onset
Absolute CI of Lytics
- active bleeding or hx of intracranial hemorrhage
- ischemic (thrombotic) stroke within 3 months
Relative CI of Lytics
- uncontrolled HTN
- current anticoagulant use (warfarin)
- pregnancy
- surgery <3 weeks
At discharge, how long should pts be kept on BBs?
- at least 6 months, ideally 3 years
- in pts with low EF, indefinitely
