What is a heart attack?

Stomach pain

Professor Newby says: “Because the heart, the gullet [the passage between your mouth and stomach] and the stomach are all lying right next to each other, the challenge, for both members of the public and doctors, is that a burning or indigestion-type pain and heart pain can be difficult to disentangle. You could call NHS 111 for advice – they have certain algorithms they apply, but they aren’t perfect as there are no hard and fast rules that apply to everyone.”
