What is a heart attack?

Choking sensation

Professor Newby says: “The word ‘angina’ actually means ‘choking’, and sometimes the tightness or pain can be up in the throat. People tend to describe a ‘restricting’ or ‘choking’ sensation.” If the feeling continues, and you haven’t previously been diagnosed with heart problem, you should call NHS 111 – but if you have some of the other signs listed here as well, it might be safer to call an ambulance.
