Is Hormone Therapy Helpful After All?
Expert Says New Findings Should Reassure Younger Women
Pluses and Minuses
Researchers Judith Hsia, MD, says there were far too few women in their 50s in the study to confirm that early estrogen use protects the heart. Most women were in their 60s and 70s when they entered the study.
"This should not be taken as a recommendation that any woman should take hormones to protect against heart disease," she tells WebMD. "The only reason to take estrogen at this point is for menopausal symptoms, and women considering the therapy need to weigh the risks and benefits carefully."
On the plus side, hormone therapy is the most effective treatment for hot flashes and other menopausal symptoms, and it has been shown to help prevent osteoporosis, she says.
On the minus side, findings suggest an increase in risk for strokes, blood clots, and dementia among long-term estrogen users.
But ob-gyn Isaac Schiff, MD, tells WebMD that there is intriguing evidence that the risks associated with estrogen and estrogen-plus-progestin may be limited to women who start taking the hormones later in life.
Schiff is chief of obstetrics and gynecology at Massachusetts General Hospital in Boston. He also chaired the American College of Obstetricians and Gynecologists (ACOG) task force on hormone therapy.
In a 2004 report, the task force concluded that hormone estrogen, or estrogen-plus-progestin, should be used for the treatment of menopause-symptoms only in the "smallest effective dose for the shortest possible time."
Schiff says many of his patients have told him that they feel better taking hormones and want to continue taking them.
"There was a lot of anxiety three or four years ago that taking hormones early in menopause would increase a woman's risk of developing heart disease," he says. "But this risk does not appear to be borne out. Some studies even suggest that the longer women are on hormones the better off they are if they start early enough."
He says the estrogen findings should be seen as reassuring to women considering hormone therapy to relieve hot flashes and other symptoms of menopause.
"We can now tell a woman in her early 50s who may have had her last period three months ago and has menopause symptoms that her risk of developing heart disease will not increase if she takes estrogen," he says. "That is the good news from this study."
