Menopausal Hormone Therapy: a Comprehensive Review.

Abstract

For decades the medical community recommended menopausal hormone therapy (MHT) for prevention of atherosclerotic cardiovascular disease (ASCVD) and osteoporosis in addition to relieving unpleasant vasomotor and genitourinary symptoms. These recommendations were largely based on observational studies. Several large randomized placebo-controlled trials led to the surprising finding that postmenopausal women were at higher risk of cardiovascular disease (CVD) events compared with women in the placebo group. For the next decade, women were less frequently prescribed MHT and more often declined MHT. Today, there are more evidence-based guidelines utilizing sex-specific ASCVD risk factors to assess risk in women. More recent studies have shed new light on safety and potential benefits for women initiating MHT earlier with newer options for route of administration, dosing, and combinations. Recent studies suggest MHT safety in younger women, women within 10years of menopause, and women who use low-dose MHT for short durations for menopause symptom relief. Transdermal, newer low-dose oral therapies and SERM therapies may also have lower risk and be reasonable considerations for women. Healthcare providers need to be aware of the current options for MHT, current indications, contraindications, long-term ASCVD risks, and nonhormonal options for high-risk women.
