Young women who smoke have a significantly greater risk of cardiac arrest than non-smoking young women, new research reports.

For women smokers ages 18 to 49, the risk of a deadly type of heart attack was more than 13 times higher than it was for non-smoking counterparts, researchers reported in the Journal of the American College of Cardiology.

[However], when women quit smoking, their risk of a major heart attack dropped back to that of non-smokers.
