NSTEMI Flashcards
Biomarker of choice to detect NSTEMI.
Troponin I
Biomarker that can be measured to detect risk of developing NSTEMI.
Brain Natriuretic Peptide (BNP)
3 characteristics indicative of NSTEMI of chest XR.
- Mediastinal Widening
- Congestive Heart Failure
- Cardiomegaly
Test of choice to determine if a patient had an MI but present with normal EKG and (-) cardiac markers.
TEE
Transesophageal Echocardiogram
Gold Standard for diagnosing NSTEMI.
Catheter based coronary angiography
Medication treatment strategy for NSTEMI vs. STEMI.
NSTEMI: similar to unstable angina. Use drugs that decrease oxygen demand by the heart or increase oxygen supply to the heart. (antiplatelets, anticoagulants, antithrombins, factor X I’s, bed rest, nitrates, beta blockers)
STEMI: due to complete occlusion of coronary vessels by a thrombus, so use thrombolytics
Drug class contraindicated in NSTEMI and UA.
Thrombolytics
When should ACE-Is be used for NSTEMI?
Within the first 24hrs. of onset if the patient has an ejection fraction t use if they have hypotension
How does an Intra-aortic Balloon Pump (IABP) treat NSTEMI?
Inserted near the arch of the aorta. Inflates during diastole to push blood retrograde toward the aortic valve and into the coronary arteries.
Deflates during systole to allow blood to pass and acts as a vacuum to remove blood from the heart.
What is the major pleiotropic benefit to administering statins to treat NSTEMI?
Anti-inflammatory effect
What is the TIMI risk score?
Assesses the risk of recurrent ischemia after an NSTEMI. The higher the risk the more beneficial invasive cardiac catheterization would be for the patient.
What is the long term treatment for patients recovering from NSTEMI?
Life-time medications. Anti-platelet (ASA is best), anticoagulant, beta blockers, nitrates, statins
Drug class to avoid post-NSTEMI for pain control.
NSAIDs
