Drinking large amounts of coffee could increase the risk of a heart attack for people with a particular form of a gene, researchers have found.
A study of 4,028 people in Costa Rica revealed that those genetically predisposed to be slow at breaking down caffeine were 64 per cent more likely to suffer cardiac arrest if they drank four or more cups of coffee a day.
The research, published in the Journal of the American Medical Association, also found that younger coffee drinkers faced higher risks.
Slow caffeine metabolisers aged under 50 who drank coffee were up to four times more likely to have a heart attack than young slow metabolisers who drank little or no coffee.

The study looked at 2,014 men and women who had had a non-fatal heart attack between 1994 and 2004 and a control group of 2,014 healthy men and women.
