AFib Complications: What You Need to Watch Out For

Atrial Fibrillation (AFib) is a type of heart rhythm disorder that affects millions of people worldwide. It occurs when the heart beats irregularly, which can cause discomfort, shortness of breath, and fatigue. While AFib can be managed with medication and lifestyle changes, it is important to understand the potential complications associated with this condition. 

AFib prevalence estimates in the United States range between 2.7 million and 6.1 million (ref. link). This number is projected to increase to 12.1 million (ref. link) by 2030

According to a 2013 study, (ref. link) the global prevalence of atrial fibrillation (AFib) was projected to reach 33.5 million in 2010. This constitutes around 0.5% of the world’s population.

What is Atrial Fibrillation (AFib):

Atrial Fibrillation is a condition in which the heart’s two upper chambers (the atria) beat irregularly and out of sync with the two lower chambers (the ventricles). This can lead to an increased heart rate and a reduced ability of the heart to pump blood effectively. The cause of AFib can be due to several factors, including age, high blood pressure, heart disease, and other health conditions.

Potential complications of AFib:

AFib can lead to several serious health problems if left untreated. Some of these complications can be life-threatening and  have a significant impact on a person’s quality of life. It is important for individuals with AFib to understand these potential complications so that they can take steps to prevent them and seek prompt medical attention if necessary. By understanding the risks associated with AFib, individuals can work with their healthcare provider to develop a personalized care plan and manage their condition effectively.

1.Stroke:

Atrial Fibrillation significantly increases the risk of stroke, which is a medical emergency that occurs when blood flow to the brain is interrupted. AFib causes blood to pool in the heart, which can form clots. A stroke can occur if a blood clot goes to the brain. People with AFib are five times more likely to suffer a stroke than those who do not have the illness.

According to the American Heart Association, (ref. link) individuals with AFib are around five times more likely to suffer a stroke than the average individual.

Signs and symptoms of stroke:

The signs and symptoms of stroke can include sudden numbness or weakness in the face, arm, or leg, particularly on one side of the body, sudden confusion or trouble speaking or understanding speech, sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination, and a sudden, severe headache with no known cause.

Prevention and treatment options

To prevent stroke, people with AFib should manage their underlying medical conditions, take their medications as prescribed, and maintain a healthy lifestyle. Anticoagulants or blood thinners are often prescribed to prevent blood clots and stroke. In some cases, procedures such as cardiac catheterization or surgery may be necessary to repair or replace heart valves that are damaged or malfunctioning.

2.Heart Failure:

Atrial Fibrillation can also lead to heart failure, which occurs when the heart becomes too weak to pump blood effectively. This can be caused by the heart working too hard to maintain a regular rhythm, which can lead to muscle damage and decreased function.

According to the National Heart, Lung, and Blood Institute (ref. link), an estimated 5.8 million Americans live with this condition.

Signs and symptoms of heart failure:

The signs and symptoms of heart failure can include fatigue, shortness of breath, a rapid or irregular heartbeat, swelling in the legs, ankles, and feet, a persistent cough or wheezing, and weight gain.

Prevention and treatment options

Preventing heart failure in individuals with AFib involves managing underlying medical conditions, taking medications as prescribed, and maintaining a healthy lifestyle. Treatment options may include medications to control heart rate and blood pressure, as well as lifestyle changes such as diet and exercise. In some cases, procedures such as cardiac catheterization or surgery may be necessary to repair or replace damaged heart valves.

3.Blood Clots:

Atrial Fibrillation increases the risk of blood clots, which can lead to serious health problems such as stroke, heart attack, and deep vein thrombosis (DVT). AFib causes blood to pool in the heart, which can form clots. A stroke can occur when a clot goes to the brain.

Signs and symptoms of blood clots:

The signs and symptoms of blood clots can include swelling in the leg, calf, or thigh, pain or tenderness in the leg; redness or warmth in the area of the clot, and chest pain or shortness of breath.

Prevention and treatment options:

To prevent blood clots, individuals with AFib should manage their underlying medical conditions, take their medications as prescribed, and maintain a healthy lifestyle. Anticoagulants, or blood thinners, are often prescribed to prevent blood clots. In some cases, a cardiac catheterization or surgery may be needed to fix or replace a heart valve that has been damaged.

4.High Blood Pressure:

Atrial Fibrillation can also cause high blood pressure, which is a common condition that occurs when the force of blood against the artery walls is too high. This can be due to an increase in heart rate, which can cause the heart to work harder to pump blood.

Dangers of uncontrolled high blood pressure:

Uncontrolled high blood pressure can lead to serious health problems, including stroke, heart attack, and kidney failure. High blood pressure can also damage blood vessels, which increases the risk of blood clots and other health problems.

Prevention and treatment options:

To prevent high blood pressure, individuals with AFib should manage their underlying medical conditions, take their medications as prescribed, and maintain a healthy lifestyle. Treatment options may include medications to control heart rate and blood pressure, as well as lifestyle changes such as diet and exercise. In some cases, procedures such as a cardiac catheterization or surgery may be necessary to repair or replace damaged heart valves.

5.Dementia:

There is a strong link between Atrial Fibrillation and an increased risk of developing dementia. The risk of dementia increases with the duration and frequency of AFib episodes, as well as with age. The exact mechanisms behind this link are not yet fully understood, but it is thought that AFib may cause damage to blood vessels in the brain and increase the risk of blood clots and stroke, both of which can contribute to the development of dementia.

Signs and symptoms of dementia:

The signs and symptoms of dementia can include memory loss, difficulty communicating, disorientation, mood swings, and changes in behavior. As the condition progresses, individuals may experience more severe cognitive decline and difficulty performing daily activities.

Prevention and treatment options:

Currently, there is no cure for dementia, but there are steps that can be taken to slow its progression. To reduce the risk of developing dementia, individuals with AFib should manage their underlying medical conditions, take their medications as prescribed, maintain a healthy lifestyle, and engage in mentally stimulating activities.

Atrial Fibrillation can lead to serious health complications, including stroke, heart failure, blood clots, high blood pressure, and dementia. It is important to be aware of the potential risks and to seek medical attention and regular monitoring to prevent and manage these complications. By working with a healthcare provider, individuals with AFib can take steps to reduce their risk and maintain their overall health.

Keep track of your heart rate and ECG during exercise by investing in a reliable heart rate monitor like the Frontier X2.
