HRT use falls among women with heart disease risk

Hormone replacement therapy (HRT) was once believed to reduce the risk of heart disease among post-menopausal women.Rates of heart disease are lower before the menopause, suggesting a protective role of the hormone estrogen. Since estrogen levels fall sharply during and after menopause HRT, which supplies estrogen, ought to help prevent heart disease. However, studies have shown this is not so and, indeed, certain forms of HRT actually increase the risk of heart attack and stroke.
