Only a few years ago, most of what we knew about heart disease, the number one killer of women, came from studies in men.
More recent research, though, is uncovering new information about the sex differences in heart disease. Here
are some of those findings, from the February issue of the Harvard Women's Health
Watch:
-- The oft-used risk-assessment tool based on information from the Framingham
Heart Study may fall short in identifying some women at high risk. Harvard Women's
Health Watch reports that out of a group of nearly 2,500 women over age 45 with
no symptoms of heart disease, 20 percent showed signs of advanced atherosclerosis
on electron beam CT scans -- yet the Framingham method had rated 94 percent
of these advanced cases at low heart risk.
-- Other studies point to fitness -- not necessarily weight -- as a guide to
heart risk in women. Researchers at the University of Florida found that women
with low fitness scores had a higher rate of heart attack, stroke, and death
than those with normal fitness, regardless of weight. Harvard Women's Health
Watch concludes that this adds to the already abundant evidence that exercise
is the single most important thing women can do for heart health.
-- A study of more than 1,500 heart attack patients in Michigan found that
women got to the hospital about 20 minutes later than men did and had to wait
longer for treatment -- circumstances that can increase the extent of heart
damage. One reason for the delay, says Harvard Women's Health Watch, is that
women may not experience stereotypical chest pressure and pain. Therefore, a
woman may not think she's having a heart attack, and hospital personnel may
not recognize her symptoms as those of a heart attack.
