Those with STEMI/ new LBBB should proceed to coronary angiogram +/- PCI immediately1
If 12 lead ECG does not suggest STEMI/ new LBBB but cardiac risk factors are present, there should be a discussion with cardiology re: coronary angiogram +/- PCI – aim should be to undergo this within 2 hours of initial event
If cardiac cause unlikely or angiography identifies no cause, consider CTB +/- CTPA and treat accordingly1
