(Ivanhoe Newswire) -- Experiencing the adverse effects of hormone
replacement therapy (HRT) may have less to do with whether women use HRT and
more with how it’s applied.
A new study reveals a woman’s age and the mode of delivery has a significant
impact on her risk of developing dangerous conditions associated with HRT. The
Women’s Health Initiative trial was stopped when researchers saw increased risk
of breast cancer and stroke among women taking HRT. But in this latest study,
researchers found younger women taking HRT (aged 51 to 54) had a 24 percent
greater risk of heart attack than women who had never taken HRT.
Researchers also found continuous HRT -- a continuous combination of estrogen
and progesterone -- increased women’s heart attack risk by 35 percent. However,
when HRT was taken on a cyclical basis – estrogen followed by a combination of
estrogen and progesterone -- women actually tended to have lower heart attack
risks compared to women who never took HRT. What’s more, if the method of taking
HRT was through the skin – either via patch or gel on the skin – the risk of
heart attack reduced more than one third.
“Our study does not change indications and duration recommendations for HRT,”
study author Ellen Lokkegaard, M.D., a gynecologist at the Rigshospitalet in
Copenhagen, Denmark, was quoted as saying. “But the main message is that when
hormone therapy is indicated for a woman, then a cyclic combined regimen should
be preferred, and that application via the skin or the vagina is associated with
a decreased risk of myocardial infarction.”
