Smoking Harder on Women's Arteries Than Men's, Scans
WEDNESDAY, Aug. 31 (HealthDay News) -- Smoking causes more
arterial damage in women than in men, a new study finds.
Researchers used ultrasound to assess the carotid arteries (neck
arteries that carry blood to the brain) in 1,893 women and 1,694
men in Finland, Sweden, the Netherlands, France and Italy.
The study found that a lifetime of smoking was associated with
thickening of the arterial walls (atherosclerosis) in both genders,
but the impact in women was more than double that seen in men.
The findings were presented Monday at the European Society of
Cardiology meeting in Paris.
The investigators also found that the effect that the number of
cigarettes smoked per day had on progression of atherosclerosis was
more than fivefold greater in women than in men.
These associations between smoking and atherosclerosis were
independent of other risk factors, such as cholesterol level,
obesity, age, blood pressure and social class, the researchers
"The reasons for the stronger effect of tobacco smoke on women's arteries are still unknown, but some hints may come from the complex interplay between smoke, inflammation and atherosclerosis," lead study author Elena Tremoli, a professor of pharmacology at the University of Milan in Italy, said in a European Society of Cardiology news release.
Because this study was presented at a medical meeting, the data
and conclusions should be viewed as preliminary until published in
a peer-reviewed journal.
