Acute Coronary Syndrome Flashcards
what conditions are classified as ACS?
- STEMI
- NSTEMI
- unstable angina
what is unstable angina?
critical narrowing of coronary artery causing ischaemia
what are the typical features of unstable angina?
- chest pain at rest or minimal exertion lasting >15min
- ECG changes
- NO rise in troponin
what is NSTEMI?
partially occluded coronary artery
what are the typical features of NSTEMI?
- chest pain at rest or minimal exertion lasting >15mins
- ECG changes (ST-depression or T-wave inversion)
- rise in troponin
how do you clinically differ between NSTEMI and unstable angina?
rise in troponin seen in NSTEMI
what is a STEMI?
completely occluded coronary artery
what are the typical features of STEMI?
- chest pain at rest or minimal exertion, lasting >15min
- ECG changes (ST elevation or LBBB)
- rise in troponin
how do you clinically differ between NSTEMI and STEMI angina?
ECG finding of ST elevation in STEMI
what group of patients are more likely to experience painless MI?
- older patients
- diabetics
how is STEMI diagnosed?
ST-segment elevation in 2 or more continguous leads
> /= 2mm in precordial leads
>/= 1mm in limb leads
how is STEMI treated?
MMONAT
- morphine
- metoclopramide
- oxygen (if stats <94%)
- nitrates
- aspirin 300mg
- ticagrelor
how is NSTEMI treated?
MMONAT
- morphine
- metoclopramide
- oxygen (if stats <94%)
- nitrates
- aspirin 300mg
- ticagrelor
when can a patient get PCI?
<12 hours of onset + <2 hours of medical contact
when does a patient get offered thrombolysis in MI?
<12 hours of onset + >2 hours of medical contact
