title: The temporal pattern of reduction of mortality risk after smoking cessation.
abstract: We investigated the excess mortality risks of former smokers according to the number of years since they quit smoking in a cohort of 21,112 men and women evaluated with coronary angiography and included in the Coronary Artery Surgery Study registry. There is a prompt decline in mortality risk within the first year of quitting. Thereafter, former smokers have a sustained, modestly elevated mortality risk for at least 20 years compared with people who never smoked. The pattern is similar in men and women, in 35-54, 55-64, and greater than or equal to 65 age groups, and in subcohorts of those with coronary artery disease and those without coronary artery disease.
