Smoking Riskier for Women

Smoking Riskier for Women

Women who smoke may develop heart disease at almost the same age as male smokers, wiping out the natural difference between the sexes, doctors say. In research presented to the European Society of Cardiology, Norwegian researchers said that women who smoke have heart attacks nearly 14 years earlier than women who don't smoke. For men, the figure is about six years. 'This is not a minor difference,' said Silvia Priori, a cardiologist at the Scientific Institute in Pavia, Italy. 'Women need to realize they are losing much more than men when they smoke,' she said. Priori was not connected to the research. Morten Grundtvig and colleagues from the Innlandet Hospital Trust in Lillehammer, Norway, looked at data from 1,784 patients admitted for a first heart attack at a hospital in Lillehammer. They found that the men on average had their first heart attack at age 72 if they didn't smoke, and at 64 if they did. The women had their first heart attack at age 81 if they didn't smoke, and at age 66 if they did. After adjusting for other heart risk factors like blood pressure, cholesterol, and diabetes, researchers found that the difference for women was 14 years and for men was six years. Previous studies looking at whether there is a difference between the genders in the risks of smoking have been inconclusive. Doctors have long suspected that female hormones protect women against heart disease. Estrogen is thought to raise the levels of good cholesterol as well as enabling blood vessel walls to relax more easily, thus lowering the chances of a blockage. Grundtvig said that smoking might make women to go through menopause earlier, leaving them less protected against a heart attack. With rising rates of smoking in women'compared with falling rates in men'Grundtvig said that doctors expect to see increased heart disease in women. 'Smoking might erase the natural advantage that women have,' said Robert Harrington, a professor of medicine at Duke University and spokesman for the American College of Cardiology. Doctors aren't yet sure if other cardiac risk factors like cholesterol and obesity also affect women differently. 'The difference in how smoking affects women and men is profound,' Harrington said. 'Unless women don't smoke or quit, they risk ending up with the same terrible diseases as men, only at a much earlier age.' (AP) [This report reprinted with permission of the Associated Press.
