Menopause and Increased Risk of Heart Disease

Scientific evidence has established an association between hormonal changes and heart disease in menopause, primarily due to the decline in estrogen levels. Estrogen has a protective effect on the heart through various mechanisms. Binding to its receptors found throughout the body, estrogen induces the widening of the blood vessels, reduces inflammation, and acts as an antioxidant. Additionally, estrogens contribute to healthy blood cholesterol levels and prevent plaque build-up in the arteries. Consequently, this hormone positively influences blood pressure, lipid profiles, and the overall health of the arteries.

In comparison to premenopausal women, menopausal women exhibit a higher prevalence of cardiovascular risk factors, including abdominal obesity, altered lipid profiles, blood sugar imbalances, arterial stiffness, and non-alcoholic fatty liver disease (NAFLD). The changes in lipid profiles in menopause are particularly well-established, marked by an increase in total cholesterol, LDL cholesterol ("bad" cholesterol), and triglycerides, coupled with a decrease in HDL cholesterol ("good" cholesterol).

Moreover, the transition to menopause brings changes in the distribution of body fat, frequently accumulating around organs such as the liver. These shifts in fat tissue contribute to insulin resistance, reducing the body's capacity to efficiently process blood sugars. Postmenopausal women encounter a twofold higher risk of NAFLD compared to premenopausal individuals.

Identifying and Assessing Cardiovascular Risk Factors

Assessing cardiovascular risk in menopause requires an individualized approach, taking into account unique factors such as family history, medical history, and lifestyle. The factors influencing heart health are complex, encompassing genetics, race, age of menopause, physical activity, diet, the presence of pre-existing conditions (hypertension, high cholesterol, diabetes, obesity), stress levels, smoking, and alcohol intake, among others.

While various screening tools exist for heart disease, the 2019 American College of Cardiology/American Heart Association (ACC/AHA) Primary Prevention of Cardiovascular Disease Guideline recommends the Pooled Cohort Equations (PCE) as a general adult cardiovascular disease risk assessment tool. This tool evaluates 10-year risk, considering variables such as age, gender, race, cholesterol levels, blood pressure, and smoking. However, studies have revealed several limitations in the use of the PCE and similar tools.

Therefore, adopting a personalized approach to heart health assessment using functional lab testing is advantageous. A Comprehensive Metabolic Panel (CMP) and Lipid Panel are appropriate starting points, providing a basic overview of metabolic health and lipid profiles. For a more comprehensive understanding of individual cardiovascular risk factors, the Doctor's Data Cardiovascular Risk Profile or BostonHeart Diagnostics' Comprehensive CardioMetabolic test can offer valuable insights into lipids, inflammatory markers, fatty acid status, and more. Functional testing significantly enhances the precision of evaluating cardiovascular risk during menopause through individualized biomarker assessment.

Dietary Strategies for Heart Health in Menopause

Maintaining a heart-healthy diet in menopause is crucial for supporting optimal cardiovascular health. Though recommendations may vary depending on the source, common goals include reducing cholesterol, balancing blood sugar, and ensuring adequate antioxidant intake. To achieve this, it is important to control calorie intake while prioritizing nutrient-rich foods.

According to USDA Guidelines, women should aim for 1,600-2,200 calories daily, incorporating 2.5 cups of vegetables, 2 cups of fruit, 6 oz. of grains (with a focus on at least 3 oz. of whole grains), and 5.5 oz. of protein from meat and plant-based sources like legumes. Notably, plant-based diets have shown benefits for postmenopausal women by lowering cholesterol levels and reducing heart disease risk.

A well-balanced diet necessitates restriction of sodium, added sugars, and certain types of fats, such as saturated and trans fats. Prioritizing the consumption of unsaturated fats, especially omega-3 fatty acids, is vital for heart health. These fats, often lacking in Western diets, offer anti-inflammatory benefits, support cholesterol management, and improve the body’s insulin response. Rich sources of healthy unsaturated fats include fatty fish, such as salmon and sardines (recommended two 3 oz. servings per week), fish oil supplements, flax seeds, walnuts, avocados, and extra-virgin olive oil.

Additionally, emphasizing fiber from fruits, vegetables, legumes, and whole grains provides protective effects against heart disease, obesity, and metabolic syndrome. Only moderate intake of dairy and animal-based proteins is advised. The Mediterranean Diet and the DASH diet, both renowned for improving heart health, reducing heart attack and stroke risk, and managing blood pressure, align well with these dietary criteria.

Physical Activity and Its Impact on Cardiovascular Health

Prioritizing exercise for cardiovascular health in menopause is critical, as it improves lipid profiles, regulates blood pressure, and supports healthy weight maintenance. Beyond these fundamental advantages, engaging in regular physical activity also improves stress management, mood, longevity, and bone density, and even reduces menopausal symptoms.

Physical activity recommendations for menopausal women involve a well-rounded approach, combining endurance (aerobic) exercises and strength training (resistance or weight-bearing) exercises.

According to the American Heart Association, women should aim for 150 minutes (2.5 hours) of moderate aerobic activity or 75 minutes of vigorous aerobic activity weekly, along with moderate- to high-intensity strengthening activity for 20 minutes at least 2 days per week. Moderate aerobic activities encompass brisk walking, water aerobics, dancing, gardening, or cycling, while more intense activities include uphill hiking, running, swimming laps, or jumping rope. These exercises elevate the heart rate and facilitate fat burning.

While aerobic exercises benefit cardiovascular health, incorporating resistance exercises is particularly advantageous for women in menopause. With estrogen decline leading to reduced bone density and lean muscle mass, resistance training becomes essential. Examples include weight training, resistance bands, or bodyweight exercises like squats. The combination of both aerobic and resistance exercises has been linked to increased estrogen levels in postmenopausal women compared to aerobic exercise alone.

To practice exercise routines safely and effectively, a proper warm-up, such as a brisk 5-minute walk, and stretching are crucial to minimize exercise-related injuries and post-exercise discomfort. Yoga and pilates are great options for stretching and enhancing flexibility, promoting improved muscle function. A cool down and stretching at the end of a workout are equally important to gradually lower the heart rate and alleviate muscle stiffness. For personalized guidance, working with a personal trainer is a valuable option to ensure safe and effective exercise.

Hormone Replacement Therapy (HRT) and Heart Health

Hormone replacement therapy (HRT) is a medical treatment in which hormones, such as estrogen and progesterone, are administered to individuals to supplement or replace the body’s natural hormones.

HRT may offer a variety of benefits for postmenopausal women, including improved sleep and bone health, relief from hot flashes, and reduced risk of heart disease. Possible risks associated with HRT include endometrial cancer, breast cancer, blood clots, and stroke. The benefits and risks must be evaluated on a personalized basis, accounting for the individual’s medical history, family history, and the primary goal of the hormone therapy.

Using hormone therapy for menopausal heart health requires careful consideration of various factors, including age and time since menopause when HRT is initiated. According to the Women’s Health Initiative (WHI) and other studies, HRT may be more beneficial for cardiovascular outcomes when initiated in women under 60 years of age or within 10 years of the onset of menopause.

A 2022 statement by the United States Preventive Services Task Force (USPSTF) recommends against the use of oral or injectable hormone therapy to prevent chronic conditions like cardiovascular disease in postmenopausal women, citing a lack of benefit. It's important to note that this recommendation refers to the prevention of chronic disease alone and does not cover the use of HRT for managing other menopausal symptoms like hot flashes.

Therefore, the decision to initiate HRT is complex and requires careful evaluation with your physician to weigh the benefits and risks.

Integrative Approaches to Menopausal Heart Health

There are various integrative approaches for menopausal heart health, encompassing herbal supplements, nutraceuticals, acupuncture, and yoga, to name a few.

Hawthorn berry (Crataegus spp.)

With a history spanning centuries, hawthorn is widely recognized for supporting heart health. Research highlights its positive impact on lipid profiles, blood pressure, antioxidant benefits, and anti-inflammatory effects.

Motherwort (Leonurus cardiaca)

Motherwort is an herb in the mint family that serves as both a calming agent for the heart and a remedy for menopausal symptoms, exhibiting positive effects on blood pressure, anxiety, and hot flashes.

Omega-3 Fish Oil

Scientifically shown to lower the risk of heart disease, fish oil supplements offer benefits such as reducing inflammation, supporting healthy blood pressure and lipid profiles, and preventing blood clot formation, ultimately improving blood flow.

Acupuncture

Renowned for alleviating menopause-related symptoms like hot flashes and heart palpitations, acupuncture is also a widely utilized method for addressing high blood pressure. Global studies suggest that acupuncture influences blood pressure through mechanisms such as enhancing blood vessel function, decreasing oxidative stress and inflammation, and increasing the body’s production of nitric oxide, a gas that widens blood vessels, thereby decreasing blood pressure.

Yoga

With a legacy spanning millennia, yoga proves beneficial for menopause and heart health by reducing stress, enhancing mobility, and increasing overall movement.

Before incorporating herbs or dietary supplements, consulting a personal physician is crucial to ensure safety, particularly if prescription medications are part of the regimen, as some herbs may contribute to blood pressure-lowering effects.
