MONDAY, Nov. 15 (HealthDay News) -- Individuals with more than 30 pack-years of smoking history who quit smoking over 15 years ago remain at an increased risk for heart failure, and the prevalence of current smoking appears to have dramatically declined among adults, according to two studies presented at the American Heart Association's Scientific Sessions 2010, held from Nov. 13 to 17 in Chicago.
In the Cardiovascular Health Study, Amiya A. Ahmed, M.D., of the University of Alabama at Birmingham, and colleagues evaluated the long-term effect of past smoking on incident heart failure among 3,855 community-dwelling adults, 65 years of age or older. Patients were categorized as never smokers or remote-smokers who quit smoking over 15 years ago. Compared to never smokers, the investigators found that remote-smokers with over 30 pack-years of smoking history had a significantly increased risk of incident heart failure.
Kristian B. Filion, of the University of Minnesota in Minneapolis, and colleagues evaluated the prevalence of smoking between 1980 and 2009 in adults aged 25 to 74 years in the Minnesota Heart Survey. The investigators found that the prevalence of current smoking declined dramatically from 1980-1982 to 2007-2009 (from 32.8 to 15.5 percent in men and from 32.7 to 12.2 percent in women), with greater decreases among those with higher income and more education.
"Future abstinence campaigns should target those of lower socioeconomic position and younger women," Filion and colleagues write.
