NICE guidelines 2010 

''Immediate management'' of ACS
glyceryl trinitrate
aspirin 300mg (not other anti-platelet outside hospital)
oxygen if sats < 94% (unless COPD then aim for 88-92%)
ECG ASAP but don't delay transfer

''Referral''
emergency - current chest pain or chest pain in the last 12 hours with an abnormal ECG
same day - chest pain 12-72 hours ago
chest pain > 72 hours ago - assess with ECG and troponin and review

''stable chest pain'' (complex tables)
base assessment on pain, age, gender, risk factors
'anginal pain'
 - constricting discomfort in the front of the chest, neck, shoulders, jaw or arms
 - precipitated by physical exertion
 - relieved by rest or GTN in about 5 minutes
if all 3 above -  angina, if 2 - atypical angina, if 1 or 0 non-anginal

If typical angina and risk of CAD >90% - no need to Ix further
If risk of CAD .....
61-90%	Coronary angiography
30-60%	Functional imaging, myocardial perfusion scan with SPECT, stress echocardiography or MR
10-29%	CT calcium scoring
