The risk of cardiovascular disease increases along with aging. There are increasing interests in researches on the protective effects of hormone replacement therapy (HRT) on cardiovascular system in postmenopausal women. In this article we will review how we have explored the evidence of different sex hormones on blood vessels since 1996. The results showed that low-dose HRT significantly protected cardiovascular system in postmenopausal women. However, the high-dose 17β-estradiol (E2), with or without progesterone (P) or testosterone (T),or any hormone alone, as their concentrations increase, may even inhibit the protective effects of low-dose HRT on blood vessels.
