Where are we with postmenopausal hormone therapy in 2005?

Abstract

Recently, two large randomized placebo-controlled studies on long-term postmenopausal hormone replacement therapy, the Heart and Estrogen/progestin Replacement Study (HERS) and the Women's Health Initiative (WHI), have raise a lot of controversies, especially on the cardiovascular aspects. We briefly review these two trials and discuss what we know and do not know about postmenopausal hormone therapy, including the evidence on novel choices such as raloxifene and tibolone.
