The ban on smoking in public places could reduce heart attacks by more than a third in some parts of the world, say researchers.
Two independent health reviews have found that heart attack rates dropped steeply in areas where bans have been introduced, with one reporting 36% fewer cases three years after smoke-free legislation came in.
Smoking in pubs, restaurants and other public spaces was banned in England and Wales in July 2007, a year after similar laws were introduced in Scotland. The Scottish ban led to a 14% fall in the number of people being admitted to hospital with a heart attack the following year.
