Smoking bans cut heart attacks by a third

Smoking bans cut heart attacks by a third

CHICAGO – Smoking bans in public places can reduce the number of heart attacks by as much as 36 per cent, offering fresh proof that the restrictions work, US researchers said on Monday.

They urged widespread bans on smoking in enclosed public places to prevent heart attacks and improve public health.’This study adds to the already strong evidence that secondhand smoke causes heart attacks, and that passing 100 per cent smoke-free laws in all workplaces and public places is something we can do to protect the public,’ James Lightwood of the University of California-San Francisco, whose study appears in the journal Circulation, said in a statement.The team pooled data from 13 studies of smoking bans in communities in the United States, Canada and Europe.They said heart attack rates fall immediately after smoking bans are put in place, dropping by 17 per cent in the first year and by as much as 36 per cent after three years.Lightwood said in a telephone interview that prior studies have been inconsistent in their findings, but their analysis found that smoking bans had a compelling effect.’A well-designed smoking restriction law can significantly reduce heart attacks in the community and has a beneficial impact on public health,’ he said.According to the US Centres for Disease Control and Prevention, long-term exposure to secondhand smoke can raise heart disease rates in adult nonsmokers by 25 per cent to 30 per cent.Secondhand smoke kills an estimated 46 000 Americans every year from heart disease alone, the CDC and Heart Association say. Smoking also causes several types of cancer, stroke and emphysema or chronic obstructive pulmonary disease.- Namapa-Reuters
