coughing vigorously during a heart attack could save your life; BUST THAT MYTH.
Byline: DR MIRIAM STOPPARD
There's no medical evidence to support "cough CPR", which suggests you can help yourself by coughing vigorously if you think you're having a heart attack and are alone.
If you had a cardiac arrest you would become unconscious, and without immediate CPR (chest compressions and rescue breaths) you would die.
If you are still conscious (and you would have to be to do "cough CPR"), then you are not in cardiac arrest. But although CPR is not needed in this case, urgent medical help is vital.
If you witness a cardiac arrest, you can increase the person's chances of survival by phoning 999 immediately and giving CPR.
