Menopause is a natural process that all women go through, and it signals the end of a woman’s reproductive years. However, it can come with a host of uncomfortable symptoms such as hot flashes, mood swings, and insomnia.

Hormone therapy (HT) is the most effective treatment for these symptoms; however, it is not without risks, especially for the heart. In this article, we will discuss the heart risks of hormone therapy for menopause.

What is Hormone Therapy for Menopause?

Hormone therapy (HT) for menopause works by replenishing the declining levels of estrogen and progesterone in a woman’s body that come with menopause.

Estrogen is a hormone that is necessary for many bodily processes, including regulating the menstrual cycle, maintaining bone density, and keeping the vagina lubricated. Progesterone, on the other hand, is responsible for preparing the uterus for pregnancy and regulating the menstrual cycle.

Types of Hormone Therapy

There are two types of hormone therapy – estrogen only therapy (ET) and estrogen plus progestogen therapy (EPT).

Women who have had a hysterectomy and therefore do not have a uterus can take ET, while women with a uterus must take EPT as estrogen alone can increase the risk of uterine cancer. Additionally, HT can be administered in various forms, including pills, patches, gels, creams, and injections.

Heart Risks of Hormone Therapy

While hormone therapy can relieve menopausal symptoms, it also comes with risks, especially for the heart. Several large-scale clinical trials have found that hormone therapy can increase a woman’s risk of heart disease, stroke, and blood clots.

The risks appear to be higher for women who start hormone therapy older than 60 or who have been in menopause for more than ten years. Although the risk of heart disease is relatively low for women in their 50s, it increases sharply after age 60.

How does Hormone Therapy Affect the Heart?

The exact mechanism by which hormone therapy increases the risk of heart disease is not fully understood, but scientists believe that estrogen plays a vital role in maintaining the health of blood vessels and reducing inflammation.

Therefore, when estrogen levels decline in menopause, the blood vessels may become stiffer and less able to relax, leading to high blood pressure or hypertension. Additionally, studies have found that hormone therapy can increase the levels of C-reactive protein (CRP), a marker of inflammation in the body, which can contribute to the development of atherosclerosis or the buildup of plaque in the arteries.

The Benefits of Hormone Therapy

Despite the heart risks associated with hormone therapy, it still has some benefits for women, especially when started at the onset of menopause.

Hormone therapy can alleviate menopause symptoms such as hot flashes, night sweats, and vaginal dryness, and in some cases, it can improve bone density and reduce the risk of fractures. Additionally, there is some evidence to suggest that hormone therapy can reduce the risk of colon cancer, but more research is needed to confirm this.

How to Reduce the Heart Risks of Hormone Therapy

If you decide to start hormone therapy for menopause, you can take steps to reduce the heart risks associated with it. First, discuss with your doctor whether HT is right for you and what type and dose would be most appropriate.

Generally, it is recommended that women take the lowest effective dose for the shortest possible time to minimize the risks. Additionally, women who smoke or have a history of blood clots, heart disease, or stroke should not take hormone therapy.

Finally, maintaining a healthy lifestyle by eating a balanced diet, exercising regularly, and avoiding smoking can also help reduce the risk of heart disease.

Conclusion

In conclusion, hormone therapy for menopause can provide significant relief to women struggling with symptoms, but it also comes with significant risks, especially for the heart.

Women who are considering hormone therapy should discuss the risks and benefits with their doctor and take steps to minimize their risks. Maintaining a healthy lifestyle is also crucial in reducing the risk of heart disease.
