The Menopause, Estrogen and Venous Events (MEVE) study was a retrospective observational study of menopausal hormone therapy and venous thromboembolism (VTE) in postmenopausal women with a previous history of VTE.[1][2][3][4][5] It found that transdermal estradiol was not associated with increased risk of VTE (HR = 1.0, 95% CI 0.4–2.4) whereas oral estrogens were associated with a large increase in risk (HR = 6.4, 95% CI 1.5–27.3).[1][3][4] The mean dose of transdermal estradiol in the study was 50 μg/day, although data on dose were missing for around 50% of women.[1][2] Similarly, a small study found that transdermal estradiol did not influence coagulation in women with prior VTE.[6] These findings are similar to studies in menopausal women without prior history of VTE which have found that transdermal estradiol has minimal influence on coagulation[7] and is not associated with increased risk of VTE at doses of up to 100 μg/day.[8][9][10][11] Menopausal hormone therapy guidelines have cited the MEVE study and recommended use of transdermal estradiol over oral estrogens in women at high risk for VTE.[12][13][14][15] However, randomized controlled trials (RCTs) are still needed to definitively confirm findings that transdermal estradiol is safer than oral estrogens in terms of VTE risk.[12][16][17]
