Decline in the Risk of Myocardial Infarction among Women Who Stop Smoking

Abstract
To assess the relation of smoking cessation to the risk of a first myocardial infarction in women, we compared the smoking habits of 910 patients who had had their first myocardial infarction with those of 2375 controls in a hospital-based case–control study of women from 25 to 64 years of age.
