Smoking, heart attack link

About 5 to 10 percent of heart attack victims don't have significant hardening of the arteries. But a disproportionate number of them, especially in the younger age groups, are smokers, says Michael J. Pecora of Emory University in Atlanta. While this association does not prove that smoking causes heart attacks in the absence of atherosclerosis, it is another reason not to smoke, says Pecora.

He and his colleagues studied 48 people who had little or no atherosclerosis yet had suffered heart attacks. Seventy-one percent had a history of smoking; the proportion was higher -- 78 percent -- for those under 60 years of age.
