Did you know that the CDC estimates that 12.1 million Americans will have atrial fibrillation by 2030?
The latest figures show that it was mentioned on over 180,000 death certificates and was the underlying cause of death in more than 25,000 of these. Clearly, atrial fibrillation is a threat that we should all take seriously.
But what is atrial fibrillation? What are the signs and symptoms of atrial fibrillation? And what should you do to reduce your risk of developing this common disease?
Let’s take a closer look at everything you need to know about atrial fibrillation.
What Is Atrial Fibrillation?
Atrial fibrillation, often abbreviated to A-fib, is an irregular heart rhythm or arrhythmia.
During normal circulation, the heartbeat maintains a steady pulse in the right atrium. This keeps the heartbeat steady and consistent and keeps the blood flowing through the atria and ventricles. This is controlled by electrical signals.
In someone with atrial fibrillation, the electrical impulses fire erratically. The upper chambers of the heart can twitch rapidly. This changes the blood flow to the rest of the heart and interrupts the normal flow of blood through the circulatory system.
Atrial fibrillation puts you at greater risk of having a stroke or heart problems.
What Causes Atrial Fibrillation?
Certain conditions can lead to a person developing this condition as they can disrupt the electrical functions of the heart. Atrial fibrillation causes include:
- Hypertension
- Heart attack
- Coronary artery disease
- Congenital heart defects
Other health conditions can also increase your risk of developing atrial fibrillation. This includes:
- Kidney disease
- Diabetes
- Overactive thyroid
- Obesity
- Sleep apnea
There are other conditions that can lead to this condition and in some people, the underlying cause is never identified. People of European ancestry are at a great risk than people of other ethnicities.
What Are the Signs and Symptoms of Atrial Fibrillation?
One of the most common atrial fibrillation symptoms is feeling your heart fluttering or an awareness of your heartbeat. You may also feel pressure in your chest and even abdominal pain.
Atrial fibrillation also causes fatigue. Because the normal circulation of the blood is disrupted, the cells don’t receive the oxygen they need when they need it.
If atrial fibrillation persists, it can lead to heart failure. In this case, atrial fibrillation signs include:
- Fluid retention
- Swelling in the hands, legs, and feet
- Shortness of breath
Living with Atrial Fibrillation
If you’re living with atrial fibrillation, medications can help. They are primarily used to thin the blood to reduce the risk of clots developing. Certain medications can also help to regulate the heart’s rhythm.
Atrial fibrillation treatment can also include lifestyle changes. Try reducing your weight if you are obese and increasing your exercise. If you have difficulty sleeping, ask your doctor if a sleep study could help you find the best treatment.
The Bottom Line on Atrial Fibrillation
If you are experiencing the signs and symptoms of atrial fibrillation, don’t delay. Schedule an appointment with your doctor and get yourself checked out.
