Heart & Breathing Changes

Menopause-related heart and breathing changes refer to the alterations in cardiovascular and respiratory functions, predominantly characterized by an irregular heartbeat (arrhythmia), including palpitations, elevated heart rate, and difficulty breathing (dyspnea). Throughout menopause, declining estrogen levels influence the autonomic nervous system, which controls the heart rate and can affect the heart rhythm, contributing to these symptoms.

Palpitations cause a sensation of a pounding, racing, or fluttering heart, which may be linked to anxiety or panic attacks. An elevated heart rate, or tachycardia, a type of arrhythmia, exceeds the normal resting rate and suggests the heart is working harder than necessary. Dyspnea, or breathlessness, can result from minor exertion, causing discomfort and anxiety.

These changes, while commonly associated with menopause, can indicate other health conditions. So, symptoms should not be dismissed and require medical intervention for correct diagnosis and treatment.

During menopause, the cause of these heart and breathing changes primarily stems from hormonal fluctuations, particularly the reduction in estrogen levels. This hormone plays an important role in managing the flexibility of blood vessels. With its decline, blood pressure can rise, causing an irregular heartbeat and an increased heart rate.

Estrogen’s reduction affects respiratory and lung function, leading to dyspnea or difficulty in breathing.

Estrogen helps to control cholesterol levels, reduce plaque buildup in arteries, and keep blood vessels healthy. Its decline increases the risk of developing coronary heart disease, a heart attack, stroke, or metabolic syndrome. Metabolic syndrome includes a cluster of risk factors like abdominal obesity, high blood pressure, impaired fasting glucose, high triglyceride levels, and low HDL cholesterol levels, specific for cardiovascular disease.

Other factors like stress, anxiety, and lifestyle habits, like smoking, can exacerbate heart and breathing symptoms. Vasomotor symptoms (VMS) such as hot flashes, night sweats and cold flashes are often accompanied by palpitations and fluctuations in blood pressure. Certain medical conditions like diabetes, cardiovascular disease, and obesity can contribute to these changes.

The symptoms associated with heart and breathing changes during menopause reflect the important role estrogen plays in cardiovascular and respiratory functions.

Symptoms include arrhythmia, which can present as Atrial fibrillation (A-fib), an irregular heartbeat, Bradycardia, a slow heartbeat, or Tachycardia, a fast heartbeat. Palpitations are symptoms of each type of arrhythmia.

Other symptoms include dyspnea, which may present as shortness of breath, chest discomfort, and rapid and shallow breathing, among others. These symptoms are primarily attributed to the reduction in estrogen levels.

Irregular Heart Rhythm (Arrhythmia)

Arrhythmia does not always show a serious medical condition. However, they can disrupt normal heart function and increase the risk of stroke or cardiac arrest, if not treated promptly.

Menopausal women commonly experience palpitations, with or without cold flashes, hot flashes, and night sweats, which are a symptom of the three types of arrhythmias: Atrial fibrillation (A-fib), bradycardia, and tachycardia.

Atrial fibrillation (A-fib), an irregular heartbeat, is when the heart chamber fibrillates or quivers, instead of producing a single, strong contraction, resulting in tachycardia, a rapid heartbeat. A-fib typically involves a rapid onset and may involve angina (a type of chest pain), breathlessness, dizziness, palpitations, weakness, and fainting or near fainting.

Expanding on palpitations, these are heartbeats that are suddenly more noticeable than regular heartbeats. During a palpitation, the heart may flutter, pound, race, or beat hard, fast, or irregularly. Palpitations may be felt in the chest, throat or next, may occur sporadically or regularly, and can last for a few seconds to a few minutes.

Bradycardia, a slow heartbeat, occurs when the heart rate is slower than usual, typically below 60 beats per minute. This decrease may come with angina, difficulty concentrating, confusion, dizziness, tiredness, lightheadedness, palpitations, shortness of breath, heavy sweating and fainting or near fainting.

Tachycardia, a rapid heartbeat, is characterized by a heart rate that exceeds the normal resting rate, typically over 100 beats per minute. This increase may be accompanied with dizziness, shortness of breath, lightheadedness, sudden weakness, rapid heartbeat, or pulse, palpitations, chest pain, or discomfort, and fainting or near fainting.

As changes in heart rhythm may feel alarming, they can be accompanied with a sense of unease, anxiety, or panic. Typically, these changes are not a sign of heart disease, however, persistent changes accompanied by symptoms such as chest pain justify medical attention. Other causes may include pregnancy, chest trauma, genetic factors, heart disease, hypothermia, and medications.

Difficulty Breathing (Dyspnea)

Dyspnea can present with a range of symptoms. These include a sensation of shortness of breath, often described as feeling like you cannot get enough air, you are gasping for air, and you need to breathe harder to take a deep breath. This can occur at rest or become worse during illness or physical exercise and activity. Other symptoms include chest discomfort or tightness, anxiety, or a sense of impending doom. Rapid, shallow breathing, known medically as tachypnea, palpitations, wheezing, or noisy breathing (stridor), may also be present.

Other associated symptoms can include dizziness, fainting, or even fatigue. Dyspnea is more likely when you do not exercise, are overweight, or have anemia, anxiety, a history of smoking, or a heart, lung, or respiratory condition, such as asthma.

In diagnosing menopause-related heart and breathing changes, a healthcare professional will begin with a comprehensive personal and family medical history, focusing on cardiovascular and respiratory health, as well as understanding the frequency and intensity of your symptoms.

A physical examination may be completed to assess your heart rate and rhythm, alongside evaluating respiratory function. This may involve listening to your lungs with a stethoscope and taking your blood pressure. The level of oxygen in your blood may also be measured.

More tests for dyspnea may include diagnostic imaging like a chest X-radiation (X-ray) or Computed Tomography (CT) scan, pulmonary function tests for lunch capacity and breathing efficiency, and cardiopulmonary exercise testing. More tests for arrhythmia may include electrocardiograms (ECGs) and echocardiograms (EKGs), to track heart rhythm, view heart structure and function, and identify irregularities. Blood tests may also be completed to rule out any other conditions.

While these symptoms are often associated with menopause, they can indicate other health conditions. A correct diagnosis aids in effective and tailored treatment strategies.

Treatment for menopause-related heart and breathing changes involves a combination of medications, therapies, and dietary supplements.

Hormone Replacement Therapy (HRT) may have some impact on cardiovascular and respiratory health, however, is rarely used as a treatment option. Some women have experienced mixed results with HRT, with some experiencing an increased risk of cardiovascular disease.

Medications to treat arrhythmia include antiarrhythmic medications to help restore normal heart rhythm, beta-blockers to slow the heart rate and reduce palpitations, and calcium channel blockers to control the heart rate. Inhaled medications called bronchodilators can help relax and open airways to treat dyspnea and help breathe more easily. Medications used to relieve pain or anxiety can help with breathlessness.

Surgical procedures and therapies for arrhythmia include cardioversion, which uses electrical shocks to reset the heart’s rhythm, and catheter ablation and maze procedure, which both help block irregular electrical impulses. Oxygen therapy may treat dyspnea to promote an adequate oxygen supply to the body.

Dietary supplements like Coenzyme Q10 (CoQ10) (Ubiquinone), magnesium, resveratrol, and vitamin K taken with vitamin D (ergocalciferol (D2) and cholecalciferol (D3)) are known for supporting heart health. Curcumin (Curcuma longa or turmeric), lycopene, and N-acetyl cysteine (NAC) are known for supporting respiratory health. Phytoestrogens, plant-based compounds that mimic estrogen in the body, can be an alternative to HRT.

Conventional therapies, such as cognitive-behavioral therapy (CBT) can give women coping strategies and techniques to handle symptoms and change negative thought patterns. Natural therapies such as biofeedback can help gain a greater understanding and subsequent control over physical responses, such as respiration, heart rate variability, blood flow, and blood pressure.

Devices such as pacemakers and implantable cardioverter-defibrillators (ICDs) can detect, control, and restore irregular heart rhythms.

The effectiveness of these treatments varies among individuals and should be discussed with a healthcare professional.

Menopause-related heart and breathing changes can be managed through lifestyle modifications and behavioral changes.

Mind-body exercises like yoga and Tai Chi and mindfulness practices like meditation, deep breathing from your abdomen, and pranayama (the yogic practice of breath regulation) can help reduce anxiety and stress, as well as help reduce the intensity of symptoms. Other breathing strategies include pursed-lip breathing where you breathe in through your nose and breathe out through your mouth with pursed lips as if you were blowing out a candle, blow-as-you-go where you breathe in and out when exerting effort like stepping or standing, and paced breathing while walking where you breathe in and then out when taking a step.

Behavioral changes include avoiding inhalation of chemicals like paint fumes or car exhaust that can irritate your lungs and impact your breathing, reducing smoking to help with breathing and arrhythmia management, and have a management plan to reduce anxiety and panic which can exacerbate palpitations.

Consuming a diet with nutrient-dense foods with Omega-3 fatty acids, enough electrolytes (particularly magnesium, sodium, phosphate, and potassium), and high-quality protein can help support cardiovascular and respiratory health. Stimulants like alcohol and caffeine are best avoided, as they can exacerbate heart and breathing symptoms.

Regular physical exercise, including cardiovascular and strength (or resistance) training, can help manage weight, and strengthen your heart and lungs. Reducing activity when the temperature is very cold, very hot or humid can be beneficial. As can ensuring you are well hydrated and any lost electrolytes are replaced. Exercise also helps promote sleep, improve sleep quality and reduce sleep disturbances.

Sexual activity releases endorphins and oxytocin, which promotes feelings of well-being. Maintaining social connections, engaging in stimulating activities, and taking part in enjoyable activities can help reduce anxiety and stress levels, supporting cardiovascular and respiratory health.

The heart and breathing changes experienced during menopause are primarily driven by a decline in estrogen, affecting cardiovascular and respiratory functions. As explored, symptoms include arrhythmia, palpitations, dyspnea, and chest discomfort or tightness. Diagnosing these changes requires a thorough evaluation, including medical history, physical examinations, and various diagnostic tests. Treatment options are diverse, encompassing medications to support heart and respiratory function, therapies such as biofeedback, and dietary supplements such as CoQ10 and resveratrol for heart health, and curcumin and NAC for respiratory health. Lifestyle changes, including mind-body exercises like yoga and Tai Chi, and mindfulness practices like meditation and various types of breathing strategies, including deep breathing, pranayama, and pursed-lip breathing, can help reduce anxiety and stress, and intensity of symptoms.
