A new American study shows half of sudden cardiac arrest victims aged 35 to 65 experience at least one symptom within four weeks of the event.
For 80 per cent of these people, the warning happens more than an hour before the arrest occurs, yet only 19 per cent of those with a symptom call 911 for help.
Only about seven per cent of sudden cardiac arrest victims survive but the likelihood of surviving is nearly five times higher if 911 is called.
While chest pain is the most common complaint, shortness of breath is an important symptom, especially for women.
Other symptoms include palpitations, nausea, vomiting and abdominal pain.
The study of 839 patients appears in the Annals of Internal Medicine. (ABC)
