A large proportion of people unlucky enough to live far from an A and E hospital department probably die at the first heart attack. However, those who manage to get rapid attention from well-qualified medical staff will most likely survive, do well afterwards and may still survive further attacks if again near to medical attention.
You might expect most people not to survive the second attack but there are cases of survival after multiple attacks. These are fairly uncommon but still noteworthy. One American doctor himself survived eight heart attacks over a six-year period, and his father survived 13 heart attacks in 15-hour period in 1994.
Retired British steel worker Brian Harries, just 44 years old, also survived 13 heart attacks over a two-day period.
