A new study has suggested the risk of coronary heart disease (CHD) has been reduced thanks to lower levels of cigarette smoke.
Researchers at the University of California, Partners Healthcare and Columbia University in the USA came together to look at how passive smoking has been dramatically cut down in public places.
It was found that during 1999, passive smoking was responsible for between 21,800 and 75,100 CHD fatalities and 38,100 and 128,900 myocardial infarctions.
However, if the rate at which passive smoking is found remains steady until the end of 2008, it was suggested this may have been cut by around 25 per cent.
Dr James M Lightwood, of the University of California, San Francisco, said that although the news was positive, it is important to remember the health risks associated with second-hand smoke.
"The future burden of passive smoking may be driven mainly by political and legal processes to ban smoking in public areas and the workplace as well as campaigns to encourage smoke-free homes," he added.
Myocardial infarctions are more commonly known as heart attacks - which can be more prevalent during winter for some groups such as the elderly.
