Hormone replacement therapy (HRT) is widely used to alleviate menopause symptoms such as hot flashes, night sweats, and vaginal dryness. It works by restoring hormone levels—most commonly estrogen— which decline with age and contribute to various menopause-related symptoms. However, there is debate about how it does impact one's cardiovascular health.HRT Options Include Hormones Dependent Upon Individuals Options in the HRT can include estrogen, progesterone, and sometimes testosterone, depending on individual needs. However, debates regarding the safety and long-term effects of HRT continue. One significant study from Penn State Hershey Medical Center found that estrogen-based therapies positively impacted cardiovascular health markers. Utilizing data from the Women’s Health Initiative, researchers compared cardiovascular health biomarkers in women using estrogen therapies to those on a placebo. They specifically examined participants on conjugated equine estrogens—commonly prescribed oral HRT—and those taking it alongside medroxyprogesterone acetate.Findings revealed that women on conjugated equine estrogens for at least one year experienced a 13% increase in high-density lipoprotein cholesterol (HDL-C), known as "good cholesterol." Those on the combined therapy saw a 7% increase. Additionally, both groups experienced an approximate 11% reduction in low-density lipoprotein cholesterol (LDL-C), the "bad cholesterol." Notably, lipoprotein(a), a type of LDL-C linked to cardiovascular risks, decreased by 15% in the estrogen-only group and by 20% in the combined therapy group.Menopause and Heart Disease RiskMenopause inherently increases the risk of heart disease due to hormonal changes. "Once a woman enters menopause, estrogen levels drop significantly, negatively impacting cardiovascular health," explained Dr. Sheryl A. Ross, a board-certified OB/GYN. This decline leads to increased artery plaque, cholesterol levels, and blood pressure, raising heart disease risk.Dr Cheng-Han Chen noted that estrogen helps maintain blood vessel elasticity, reduces LDL, and promotes HDL cholesterol production. Thus, long-term estrogen supplementation can help restore these cardiovascular benefits.HRT and Insulin SensitivityAnother study was presented at the 2024 Annual Meeting of The Menopause Society in Chicago and indicated that HRT is associated with improved insulin sensitivity in postmenopausal women. A meta-analysis involving 29,287 participants found that those on estrogen or estrogen plus progestogen exhibited better insulin sensitivity, an important factor in diabetes factor. It was concluded that HRT could enhance metabolic health by regulating insulin production and maintaining healthy body weight and fat distribution.Who Should Consider HRT?Despite the positive findings, HRT isn’t suitable for everyone. Certain individuals may experience varying effects or side effects from HRT. Dr. G. Thomas Ruiz cautioned that oral HRT could elevate the risk of clotting due to liver metabolism, while bioidentical hormones, absorbed through the skin, may have fewer risks.HRT can also play a crucial role in preventing osteoporosis, a significant concern for menopausal women. However, those with a history of blood clots, stroke, ischemic heart disease, or breast cancer may not be ideal candidates for HRT.
