Pay Attention to Irregular Heartbeat!
Atrial fibrillation (AF) is a common type of heart rhythm disorder that affects millions of people worldwide. It occurs when the upper chambers of the heart, called the atria, beat chaotically and out of sync with the lower chambers, called the ventricles. This can cause blood to pool in the atria and form clots, which can travel to other parts of the body and cause serious complications, such as stroke, heart failure, and dementia.
Some people with AF may have noticeable symptoms, such as palpitations, shortness of breath, chest pain, dizziness, or fatigue. However, some people may have no symptoms at all, or only experience them occasionally. This makes AF a silent and dangerous condition that can go undetected for a long time. The only way to diagnose AF is by performing an electrocardiogram (ECG), which records the electrical activity of the heart. Therefore, it is important to pay attention to your heartbeat and seek medical attention if you notice any irregularities or changes in your heart rhythm.
The risk of developing AF increases with age, especially after 65 years old. About one in ten people aged 80 and above have AF. Other factors that can increase the risk of AF include high blood pressure, heart disease, diabetes, obesity, smoking, alcohol consumption, sleep apnea, and thyroid problems. If you have any of these conditions, you should consult your doctor regularly and follow their advice on how to manage them. You should also adopt a healthy lifestyle, such as eating a balanced diet, exercising regularly, reducing stress, and avoiding caffeine and other stimulants. These measures can help prevent or delay the onset of AF, as well as improve your overall health and well-being.
Do Not Underestimate Atrial Fibrillation – Don’t Let Clots Hinder Your Quality of Life
One of the most serious and life-threatening complications of AF is stroke. People with AF have a five times higher risk of having a stroke than people without AF. Moreover, strokes caused by AF tend to be more severe and have worse outcomes than strokes from other causes. This is because the clots that form in the atria due to AF can be large and block major arteries in the brain, resulting in extensive brain damage and disability.
Stroke is not the only complication that can result from AF. Clots can also travel to other organs and cause damage, such as intestinal infarction, limb ischemia, or kidney failure. Additionally, AF can affect the function of the heart and lead to heart failure, which is a condition where the heart cannot pump enough blood to meet the body’s needs. Heart failure can cause symptoms such as shortness of breath, swelling of the legs, fatigue, and reduced exercise capacity. It can also increase the risk of death from cardiac arrest or other causes.
Actively Seek Treatment to Reduce the Risk of Stroke
Preventing stroke and alleviating symptoms to avoid impacting life are the primary goals of drug treatment for atrial fibrillation. Since the probability of a stroke varies for each patient based on age, weight, and various physical conditions, atrial fibrillation patients who actively seek treatment can reduce the risk of stroke by about 64%. Clinically, doctors use the “CHA2DS2-VASc score” to assess the risk of ischemic stroke due to atrial fibrillation. The higher the score, the higher the probability of a stroke due to atrial fibrillation. Regular use of oral anticoagulants is recommended to prevent stroke. In addition, in some specific patients, actively regulating the rhythm of the heart through treatments such as medication or catheter ablation may reduce symptoms or restore normal heart rhythm in atrial fibrillation.
However, drug treatment and catheter ablation are not suitable for all patients. Some patients may have contraindications or intolerances to anticoagulants, or may have a high risk of bleeding or recurrence after catheter ablation. For these patients, a minimally invasive surgical procedure called left atrial appendage occlusion (LAAO) may be an option. The left atrial appendage is a small pouch-like structure in the upper left chamber of the heart, where blood clots often form in atrial fibrillation. By sealing off the left atrial appendage with a device, LAAO can prevent blood clots from escaping and causing stroke. Studies have shown that LAAO can reduce the risk of stroke by 75% and the risk of mortality by 52% in patients with atrial fibrillation who are not suitable for anticoagulation.
Therefore, atrial fibrillation patients should consult their doctors about the best treatment option for them, based on their individual risk factors and preferences. By actively seeking treatment, they can reduce the risk of stroke and improve their quality of life.
Two Major Risk Factors
Hypertension and age are the two major risk factors for developing atrial fibrillation. Data from clinical trials involving over ten thousand people worldwide show that approximately 60% to 80% of atrial fibrillation patients also have hypertension. Since atrial fibrillation may not always have obvious symptoms and is associated with potential stroke risk, it is also emphasized to pay attention to blood pressure measurement. If the blood pressure monitor has the function of detecting arrhythmia, when such a warning is detected, it is recommended to visit a cardiology clinic for evaluation. This helps clarify the presence of arrhythmia and provides an opportunity to detect asymptomatic atrial fibrillation.
Age is another important risk factor for atrial fibrillation. The prevalence of atrial fibrillation increases with age, from less than 1% in people under 60 years old, to more than 10% in people over 80 years old. Aging causes structural and functional changes in the heart, such as fibrosis, inflammation, and oxidative stress, which can disrupt the normal electrical activity and lead to atrial fibrillation. Moreover, aging is also associated with other comorbidities, such as diabetes, obesity, and sleep apnea, which can further increase the risk of atrial fibrillation.
Therefore, it is important to monitor and control blood pressure and other cardiovascular risk factors, especially as one gets older. Lifestyle modifications, such as regular exercise, healthy diet, weight management, smoking cessation, and moderate alcohol consumption, can help prevent or delay the onset of atrial fibrillation. In addition, screening for atrial fibrillation in high-risk populations, such as the elderly, can facilitate early diagnosis and treatment, and reduce the risk of stroke and other complications.
Frequently Asked Questions
What are the symptoms of atrial fibrillation?
Atrial fibrillation (AFib) is a type of irregular heartbeat that can cause various symptoms, depending on the severity and frequency of the condition. Some of the common symptoms of AFib are:
- Palpitations: This is the sensation of feeling your heart beat rapidly, irregularly, or abnormally in your chest, throat, or neck. Palpitations can be uncomfortable and distressing, and may interfere with your daily activities.
- Fatigue: You may feel tired, weak, or exhausted due to the reduced blood flow and oxygen delivery to your body organs and tissues. Fatigue can also affect your mood, concentration, and memory.
- Shortness of breath: You may have difficulty breathing, especially when lying down, exercising, or under stress. This is because your lungs may not receive enough blood and oxygen, and may accumulate fluid due to the increased pressure in your heart.
- Chest pain or discomfort: You may experience pain, pressure, tightness, or heaviness in your chest, especially if you have underlying heart disease or coronary artery disease. Chest pain can be a sign of a heart attack, which requires immediate medical attention.
- Dizziness or lightheadedness: You may feel faint, dizzy, or unsteady due to the irregular blood flow and oxygen supply to your brain. You may also have blurred vision, confusion, or loss of consciousness.
Some people with AFib may not have any symptoms, or may only experience them occasionally. However, even if you do not have symptoms, AFib can still increase your risk of stroke and other complications. Therefore, it is important to get diagnosed and treated as soon as possible.
What are the complications of atrial fibrillation?
AFib can lead to serious and potentially life-threatening complications, such as:
- Stroke: This is the most common and dangerous complication of AFib. Stroke occurs when a blood clot blocks a blood vessel in the brain, depriving it of oxygen and causing brain damage. People with AFib have a five times higher risk of stroke than the general population, and AFib-related strokes tend to be more severe and disabling. The risk of stroke can be reduced by taking blood-thinning medications, such as warfarin or newer anticoagulants, as prescribed by your doctor.
- Heart failure: This is a condition where the heart cannot pump enough blood to meet the body’s needs. AFib can cause or worsen heart failure by reducing the efficiency and output of the heart, and by increasing the pressure and workload on the heart. Heart failure can cause symptoms such as shortness of breath, swelling in the legs and ankles, weight gain, and reduced exercise tolerance. Heart failure can be managed by taking medications, such as beta-blockers, angiotensin-converting enzyme inhibitors, or diuretics, as well as by following a low-salt diet, limiting fluid intake, and avoiding alcohol and tobacco.
- Other heart problems: AFib can also increase the risk of other heart problems, such as heart attack, angina, cardiomyopathy, and valve disease. These conditions can cause chest pain, breathlessness, and reduced quality of life. They can be treated by medications, surgery, or other procedures, depending on the cause and severity.
AFib can also affect your mental and emotional health, by causing anxiety, depression, stress, and reduced self-esteem. You may also face challenges in your work, social, and family life, due to the impact of your symptoms and treatments. You can cope with these issues by seeking professional help, joining a support group, educating yourself and others about AFib, and maintaining a positive outlook.
How can I reduce my risk of atrial fibrillation?
There are several lifestyle changes and preventive measures that can help you lower your risk of developing or worsening AFib, such as:
- Maintaining a healthy weight: Being overweight or obese can increase the strain on your heart and increase the risk of high blood pressure, diabetes, and sleep apnea, which are all risk factors for AFib. Losing weight can improve your heart function and reduce your AFib symptoms and complications. You can achieve a healthy weight by following a balanced diet that is low in fat, sugar, and salt, and high in fruits, vegetables, whole grains, and lean protein. You should also limit your intake of alcohol, caffeine, and processed foods, as they can trigger or worsen AFib.
- Getting regular physical activity: Being physically active can strengthen your heart, lower your blood pressure, improve your blood circulation, and reduce your stress levels, which can all help prevent or manage AFib. You should aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, cycling, or swimming. You should also include some strength training and flexibility exercises in your routine. However, you should avoid excessive or strenuous exercise, as it can overwork your heart and trigger AFib. You should also consult your doctor before starting any new exercise program, especially if you have heart disease or other medical conditions.
- Quitting smoking: Smoking can damage your heart and blood vessels, increase your blood pressure and heart rate, and make your blood more likely to clot, which can all increase your risk of AFib and stroke. Quitting smoking can improve your heart health and reduce your AFib symptoms and complications. You can seek help from your doctor, pharmacist, or counselor, or use nicotine replacement products, such as patches, gums, or lozenges, to help you quit. You should also avoid exposure to secondhand smoke, as it can also harm your heart.
- Managing stress: Stress can affect your heart rhythm and blood pressure, and can trigger or worsen AFib. Stress can also make you more likely to engage in unhealthy behaviors, such as overeating, drinking, or smoking, which can further increase your risk of AFib and stroke. You can manage your stress by practicing relaxation techniques, such as deep breathing, meditation, yoga, or tai chi. You can also find healthy ways to cope with your emotions, such as talking to someone you trust, writing in a journal, or listening to music. You should also try to avoid or limit the sources of stress in your life, such as work, family, or financial problems, and seek professional help if needed.
- Controlling other medical conditions: Having other medical conditions, such as high blood pressure, diabetes, thyroid disease, sleep apnea, or heart disease, can increase your risk of AFib and its complications. You can control these conditions by taking your medications as prescribed, monitoring your blood pressure, blood sugar, and thyroid levels regularly, and following your doctor’s advice on diet, exercise, and lifestyle. You should also report any new or worsening symptoms to your doctor, and have regular check-ups and tests to assess your heart function and rhythm.
By following these tips, you can reduce your risk of AFib and improve your overall health and well-being.
