Menopause, Perimenopause, and Congenital Heart Disease
What You Need To Know
If you were born with congenital heart disease (CHD), you’ve likely spent much of your life paying close attention to your heart health. As you move into midlife, another important health transition may be starting — perimenopause and menopause. These changes are a normal part of aging, but for women with CHD, they deserve a little extra attention and planning.
What Are Perimenopause and Menopause?
Perimenopause (Transition)
Often starts eight to 10 years before menopause, typically in the mid-to-late 40s, but some may experience this transition earlier, particularly if they have complex, cyanotic or high-risk heart lesions. This can begin as early as the mid-to-late 30s or early 40s.
Menopause (Milestone)
This is a single point in time, not a phase. It is medically defined as having gone 12 consecutive months without a menstrual period. The average age for reaching menopause in the United States is 51.
Early/Premature Menopause: Women with complex CHD, cyanosis (low oxygen levels), or those who have had surgeries like the Fontan procedure may experience earlier menopause, sometimes before age 40 or 45, which increases their risk of coronary heart disease and osteoporosis. During this time, hormone levels — especially estrogen — fluctuate and then decline. This can lead to symptoms such as hot flashes or night sweats, sleep problems or fatigue, mood changes or brain fog, weight changes and vaginal dryness or discomfort.
Hormone Therapy: Is It Safe for People With CHD?
Hormone therapy (sometimes called hormone replacement therapy or HRT) is the most effective treatment for hot flashes and night sweats. It also offers long-term health benefits, including preserving bone density to prevent osteoporosis and protecting cardiovascular health, especially when initiated within 10 years of menopause.
However, it is not the right choice for everyone, especially for people with certain heart conditions. Current expert guidance suggests:
- Oral estrogen pills may increase the risk of blood clots and are often avoided.
- Estrogen patches, gels or sprays may carry lower risk for some people.
- Low-dose vaginal estrogen (used for dryness or discomfort) is generally considered safe for most people, even when systemic hormones aren’t recommended.
Adults with congenital heart disease are typically considered to have a higher cardiovascular risk, particularly those with cyanotic heart disease, Fontan circulation, pulmonary hypertension, prosthetic heart valves, synthetic material or conduits, prior thromboembolism, stroke or significant arrhythmias.
Historically, menopause hormone therapy (HT) carried strong cardiovascular warnings due to older data. However, the FDA has recently lifted the long standing black box warning on many hormone-based menopause drugs, reflecting improved understanding that HT is generally safe when started within 10 years of menopause onset or before age 60 for appropriate candidates — though this doesn’t directly cover women with CHD.
The most important thing to know is that hormone therapy decisions should always be individualized and made together with your ACHD cardiologist and gynecologic or primary care provider.
What If Hormones Aren't An Option?
Lifestyle and Mind-Body Approaches
Exercise
Regular physical activity, including strength training, helps manage weight, improve mood and protect bone density.
Diet
Incorporating soy, flaxseed and legumes, which contain phytoestrogens, may offer mild symptom relief.
Stress Reduction
Yoga, meditation and deep-breathing exercises can reduce the severity of symptoms.
Weight Management
Losing weight can reduce the frequency and intensity of hot flashes and night sweats.
Environment
Dressing in layers, keeping the bedroom cool and using fans can manage hot flashes.
Cognitive Behavioral Therapy (CBT)
Cognitive Behavioral Therapy (CBT): CBT is an effective, evidence-based approach to managing mood swings, depression, anxiety and improving sleep quality.
Prescription Medications
SSRIs/SNRIs
Paroxetine (Brisdelle) is FDA-approved for hot flashes, while others like venlafaxine and escitalopram are also effective.
Gabapentin
Used for chronic pain, it is effective in reducing night sweats and improving sleep.
Fezolinetant (Vioza)
A newer, nonhormonal drug that directly targets the brain’s temperature regulation center to reduce hot flashes.
Clonidine
A blood pressure medication that can sometimes alleviate hot flashes.
The Bottom Line
Menopause and perimenopause are normal life stages, but for people with congenital heart disease, they come with unique considerations. With the right information, careful monitoring and a team-based approach to care, you can navigate this transition safely and confidently. If you have questions or concerns, don’t hesitate to ask. Your care team is there to support you at every stage of life.
