Smoking bans cut the number of heart attacks in Europe and North America by up to a third, two studies report.
Second-hand smoke is thought to increase the chances of a heart attack by making the blood more prone to clotting, reducing levels of beneficial "good" cholesterol, and raising the risk of dangerous heart rhythms.
Dr James Lightwood, of the University of California at San Francisco, led the Circulation study that pooled together 13 separate analyses.
His team found that heart attack rates across Europe and North America started to drop immediately following implementation of anti-smoking laws, reaching 17% after one year, then continuing to decline over time, with a 36% drop three years after enacting the restrictions.
Latest figures show at least 70,000 lives have been saved by NHS Stop Smoking Services in the 10 years since they were established in England.
