Is Menopausal Hormone Therapy Risky for Your Heart?
Published: Feb 02, 2024
Menopausal hormone therapy (MHT) can ease menopause symptoms, but how does it affect your heart? Let's explore the potential cardiovascular risks associated with MHT.
Hormone Therapy and Heart Disease
Initially, it was believed that MHT could help prevent heart disease, but large studies like the Women's Health Initiative (WHI) showed otherwise. The research found that MHT did not protect against heart disease and might even increase the risk, especially in older women. Factors such as age, hormone type, and timing of therapy play crucial roles in determining heart health risks associated with MHT.
Age and Timing Matter
The 'timing hypothesis' suggests that starting MHT closer to menopause might be safer for the heart than beginning it later. Younger women on MHT showed fewer heart issues compared to older women who started MHT long after menopause. This indicates that the timing of hormone exposure is key in evaluating heart risks.
Estrogen and Progestin Effects
Estrogen alone may pose less heart risk compared to combined estrogen-progestin therapy. Studies show that adding progestin can increase the risk of heart disease. The type of progestin used might influence these outcomes, with some forms being more harmful than others.
