A 45-year-old woman presents with ongoing chest pain. Immediate observations reveal BP 140/80 mmHg, heart rate 90 bpm, and saturations 99% on room air.
What should you do next?
An ECG should be performed as soon as possible as prompt diagnosis of ST elevation MI is essential. Nevertheless, the majority of patients presenting with chest pain are of non-ischaemic origin and so the other treatments may not be necessary. If ACS is suspected, aspirin should be given first. Oxygen is not recommended in the chest pain algorithm unless saturations are <94% (aim 94–98% or 88–92% if COPD).
