Acute Coronary Syndrome (ACS) Flashcards
Acute Coronary Syndrome is due to what type of thrombosis?
Platelet-mediated thrombosis
What are the 3 different types of Acute Coronary Syndrome (ACS)?
Unstable Angina, NON-ST Elevated MI (NSTEMI), ST-Elevated MI (STEMI)
What are some defining features of Unstable Angina?
Unpredictable chest pain (can be relieved with nitro), NEGATIVE TROPONINS, ST depression, or T-wave inversion on ECG
What are some defining features of NSTEMI?
Troponin POSITIVE
ST-depression, T-wave inversion, unrelenting chest pain
What are some defining features of STEMI?
Troponin POSITIVE
ST ELEVATION in 2 or more contiguous leads, unrelenting chest pain
Whatis Prinzmental’s Angina?
A type of unstable angina associated with transient ST segment elevations
CORONARY ARTERY SPASM, occurs at rest, trop negative, can be precipitated by drugs or alcohol
NTG for pain
When assessing an ECG for ACS, what are the 3 possible outcomes?
ST Elevation…STEMI
ST depression, T-wave inversion….NSTEMI, UA
No acute change
What 4 medications are given for suspected ACS
Aspirin (given asap bc it improves morbidity/mortality)
Anticoagulant (heparin or enoxaparin)
Antiplatelet
Beta blocker that is cardioselective like metoprolol
What medications are typically used to treat pain associated with ACS
NTG
Morphine
