Heart Risk Hormone Replacement Therapy?

For the full list of conditions that rule hormone therapy out, and what to use instead, see who should not take HRT.

If you are considering hormone therapy for menopause symptoms, you may be wondering about heart risk and whether it is right for you.

Hormone replacement therapy (HRT) is prescribed for postmenopausal women to relieve hot flashes and other menopause symptoms.

Some research studies recommend that HRT, specifically estrogen alone, may not influence, or may even lower the risk of heart disease when taken early in postmenopausal years. Hormone therapy is not FDA-approved or recommended to prevent heart disease.

Update: the FDA changed hormone therapy labels in 2025 and 2026

In November 2025 the FDA announced it would remove the broad boxed warnings about heart disease, breast cancer and dementia from menopausal hormone therapy products, and in February 2026 it approved the first revised labels. The agency kept the warning about endometrial cancer for women with a uterus who take estrogen without a progestogen.

The FDA’s review found that for women who start hormone therapy within 10 years of menopause, typically before age 60, the benefits are likely to outweigh the risks. That matches the advice below: timing, dose, the form of estrogen and your own health history matter most.

Putting heart risk in perspective

Your heart risk depends on several factors:

• For a healthy woman who starts HRT early in menopause, any added heart risk is small. When symptoms are significant, the benefits of hormone therapy may outweigh the risks.
• Family history, personal medical history and lifestyle also affect risk. If your cardiovascular risk is low and your menopause symptoms are significant, HRT may be an option.
• There are differences in risk profiles for women with early natural menopause or premature ovarian failure. If your periods stopped prior to age 40 or ovaries were non-functional before age 40, you have a different set of heart and cardiovascular risks compared to women who reach menopause closer to the age of 51. Risk of coronary heart disease also increases. In this situation HRT is generally recommended to protect heart and bone health, and your doctor might suggest that you take hormone therapy until around age 51 when most women enter menopause.

Your risks will vary based on:

• Whether estrogen is prescribed by itself or with progestin
• Current age and the time you started menopause
• Dosage, type of estrogen – pill, patch, cream, etc.
• Various health risks, including family history and cancer risks

Who should not take HRT

If you’ve had a heart attack, HRT is not for you. For those with heart disease or who have a background of blood clots, the risks of hormone treatment may outweigh the benefits.

Women with a history of estrogen-sensitive breast or endometrial cancer may need further evaluation before considering HRT.

Minimize your risks

Talk with your doctor about ways to reduce your risks:

• Consider the form of HRT with your doctor. HRT is available as pills, patches, vaginal cream, gels and slow-releasing suppositories.

  Low-dose vaginal preparations of estrogen, which come in cream, tablet, or ring form, can effectively treat vaginal symptoms while minimizing absorption to the whole body. Hormones delivered through the skin bypass the liver, and studies suggest patches carry a lower risk of blood clots than pills.

• Use a dose suited to your needs. Risk varies with the form of HRT, how it is given and how long you use it. Talk with your doctor about your goals and risks.

• Lifestyle also affects heart risk. Exercise regularly, do not smoke and eat a balanced diet. Regular checkups can help detect heart disease early.

• Keep up with recommended cancer screenings, including mammograms and pelvic exams.

Menopause can be difficult but there’s help

Heart disease should be taken seriously no matter what age you are. Among American women, about 1 in 5 deaths each year is from heart disease.

Most healthy women under 60 who start HRT within 10 years of menopause do not have a significant increase in heart disease risk. Risk is lowest for women closest to their last menstrual period. Risk is higher in women who start later, after more time since menopause.

If menopause symptoms affect your daily life, discuss hormone therapy with your doctor. Hormone replacement therapy may be an option, with a plan that considers your risks.
