ACS Flashcards
What is the difference between plaque, stable and unstable angina?
Plaque - test results are normal
Stable - atherosclerotic plaque
Unstable - thrombosis (rupture red cap)
What is ACS?
Quick process due to sudden clotting and can occur randomly
Pain goes for longer than 10 mins and GTN doesn’t work
Includes unstable angina, MI (STEMI or NSTEMI)
What is the difference in lab test between STEMI and NSTEMI
STEMI - high troponin and High CK
NSTEMI - high troponin but normal CK
In unstable angina - high risk stage - small troponin is detected because of small leak
What are the normal levels of troponin and CK?
Troponin -
When pt comes into the ED, what are the early managements they must go through?
Aspirin Clopidogrel Statin Beta blocker (depends) ACEI Nicotine patch GTN
What happens to the patient if they were diagnosed with STEMI at the ED?
Give them heparin or LMWH before stent Give second antiplatelet Give reperfusion-thrombolysis (tPA rPA TNK-tPA) or PCI (stent) Statin ACEI
What are the contraindications of fibrinolytics?
Risk of bleeding (active bleeding / closed head or facial trauma within 3 months,peptic ulcer)
Risk of intracranial haemorrhage (any prior intracranial bleeding, ischaemic stroke within 3 months, cerebral vascular lesion)
Pregnancy
What do we need to be aware about tPA?
It only breaks down the fibrin so it has no effect on platelet aggregation (need to use antiplatelet)
It does not prevent new fibrin generation (need to use heparin)
What happens if the patient was diagnosed with NSTEMI in the ED?
Give second antiplatelet If high risk, give heparin or LWMH IF HIGH RISK, give G2B/3A INHIBITOR If high risk, PCI Statin Maybe ACEI
Risk scores for NSTEMI is called what
And how can we use this
TIMI
3 or more traditional CAD risk factors (>65yo, 2 or more angina eps in last 24hrs, used aspirin in last 7 days, high enzyme…) –> PCI in 48 hours
Less than 3 –> drugs and exercise, maybe PCI
What is the secondary prevention for ACS
Aspirin (good for secondary prevention but not primary)
- aspirin + licagrelor (NOT FOR STROKE ONLY PT)
Statin in high dose (fibrates are not rly good)
BB (Stable, STEMI, NSTEMI)
- metoprolol (NOT propranolol)
ACEI (in MI + HF or HF alone, not really MI alone)
What meds should be avoided??
SNRI (venlafaxine) can put work on heart –> choose SSRI
TCA (amitriptyline) can risk MI –> choose SSRI
NSAIDs and cox2 inhibitors –> use naproxen
Oestrogen
Chemotherapy
Calcium
The baseline risk of death and MI decreases with which combination?
Aspirin + ticagrelor + Statin + BB + ACEI
