Presentation similar to ACS but on exertion +/- relieved by rest or GTN within 5 mins
Stable angina is a clinical diagnosis.
True or False
True
Investigations if unsure:
- FBC (anaemia exacerbates angina)

The ECG of the gardener shows ST depression. You are now sure that she has stable angina.
How would you manage this?
Conservative - Lifestyle: diet, exercise, stop smoking, reduce alcohol, relaxation
Medication:
1. B-Blockers or CCB (if both don’t work or contra –> IMN)
- Episodic relief - GTN spray
- Manage CV risk factors - ACE-In, Statins, Aspirin
(Surgical - CABG or PCI if appropriate)
What counsel do you need to give when prescribing the GTN spray?
GTN spray is for relief from episodes of chest pain.
Symptoms should resolve within 5 mins of using the spray. If not, have another spray.
If symptoms STILL PERSIST after those 5 mins or they are getting WORSE then call 999
Common SE: facial flushing, headache, light-headedness
Stable angina can be classification into typical, atypical or non-angina pain?
How many for 3 core symptoms need to be present in each classification?
