Acute Coronary Syndromes 2 Flashcards
How can ischaemia develop to infarction?
Atheroma in vessels causes aggregation (combining) of platelets causing a thrombosis (clott) which blocks the vessel
Clott can also travel down bloodstream and block the vessel further down
Blockage of the femoral and popliteal arteries causes…
Infarction of Limbs
Blockage of the carotid arteries causes…
Infarction of brain
Blockage of the coronary arteries causes…
Infarction of heart
What are the signs of myocardial infarction occuring?
- Pain, nausea, pale, sweaty (Autonomic NS activated)
- ‘going to die’
- Sometimes no symptoms or signs, SILENT MI’s
Myocardial Infarction diagnosis investigations include:
- History
- ECG (either NSTEMI or STEMI)
- ELEVATED Troponin levels
What happens to a patient if MI occurs?
- Get patient to hospital alive
- Acute angioplasty or stenting
- Thrombolysis if suitable
- Drug treatment to reduce tissue damage
- Prevent recurrence/complications (secondary prevention)
What is thrombolysis?
A procedure to dissolve blood clots (a thrombus)
When would thrombolysis be done?
If angioplasty & stent isnt possible or if patient has been delayed admission
What are complications of myocardial infarction?
- Death
- Post MI arrhythmias
- Heart failure
- Ventricular HYPOfunction
- DVT
What are long term medical management options for MI?
Prevent next MI:
- aspirin and risk modification
- B blocker
- ACE inhibitor
Treat complications:
- Heart failure
- Arrhythmias
