Heart attack symptoms, an elaboration12-23

Although chest pain or discomfort is a commonly established symptom of heart attack, some people may not experience chest pain at all, while others may experience only mild chest pain or discomfort

Occurrence of symptom(s) in isolation or in combination also sees inter-individual variations. Not everyone having a heart attack has typical symptoms.

If a person has already had a heart attack, his symptoms may not be the same for another one. However, some people may have a pattern of symptoms that recur.
