• Diagnosis & treatment are essential for preventing complications, while prevention strategies include adopting a healthy lifestyle & controlling existing health conditions.

Understanding Atrial Fibrillation

Atrial fibrillation, or AFib, is an irregular heart rhythm that originates from the upper chambers of the heart, known as the atria. It is estimated that over 33 million people aged 55 and older have been diagnosed with AFib globally. According to the Heart Rhythm Society, atrial fibrillation can lead to:

• the formation of blood clots in the heart

• increasing the risk of stroke

• heart failure

• other cardiac complications.

The chaotic electrical signals in the atria cause a fast and irregular heart rhythm in atrial fibrillation. This condition will usually require treatment to prevent blood clots and reduce the risk of serious complications. In some cases, atrial fibrillation may progress from paroxysmal atrial fibrillation, which may go away on its own, to persistent AFib, which necessitates treatment to make it go away.

What Causes AFib: Primary Causes of Atrial Fibrillation

The primary causes of atrial fibrillation are often related to structural abnormalities of the heart. Heart diseases and health conditions that may lead to AFib include:

• Advanced age: The most common cause of atrial fibrillation and the most significant one is age. If you ever see graph of people who have atrial fibrillation based by age, the prevalence of AFib starts to significantly increase as patient reach about 60 years of age.

  The incidence of atrial fibrillation continues to increase sharply as people get older, to the point that when people get close to 80 years old, that prevalence of people having AFib gets close to about 10%.

  This is usually attributed to age-related fibrosis. As people get older, they develop scar tissues inside of their heart, not that different from people getting wrinkles as they age as a comparison. People get fibrosis and scarring in their heart as they age, which can then lead to atrial fibrillation.

• Heart surgery or stress associated with surgery or illness

• High blood pressure

• Coronary artery disease: Having had coronary artery disease in the past, such as a past heart attack or coronary artery stent placement, significantly increases risk for atrial fibrillation.

• Heart valve disease: Particularly mitral valve disease such as mitral regurgitation and mitral stenosis. Aortic valve disease such as aortic stenosis or aortic insufficiency also increase risk but are less strongly associated with AFib when compared to mitral valve disease.

• Congenital heart defects

• Congestive Heart Failure or other Cardiomyopathy

• Pericarditis

• Hyperthyroidism

• Lung diseases: The lungs are very closely associated to the heart and people who have lung diseases, whether that’s COPD or emphysema, or significant asthma can also have risk for developing atrial fibrillation. When people have lung disease, they have increased pressure inside of the lungs which then gets transmitted over to their heart and that could eventually lead to episodes of atrial fibrillation.

• Sleep apnea: Another risk factor that is also common associated with obesity that can also cause atrial fibrillation is sleep apnea. There’s been a very strong association with sleep apnea and the development of atrial fibrillation and there have actually been a lot of studies showing that the treatment of sleep apnea can also improve a person’s atrial fibrillation.

• Obesity: Obesity is also a cause of atrial fibrillation by itself due to its association with other health conditions like high blood pressure and diabetes; but obesity by itself can also be a cause for atrial fibrillation. There’s actually a lot of recent data that has shown how much weight loss can actually improve a person’s atrial fibrillation.

• Endurance Training: Another risk factor for developing atrial fibrillation, which is still trying to be understood a bit more is endurance training. People who do long term endurance exercises, for example, long term endurance bike riding like MS 150’s, or triathlons, or marathon runners. These really extreme long distance exercise patients can develop atrial fibrillation as well.

  Some studies have shown that in these people who do endurance exercises end up developing some fibrosis in their atrium, which can lead to episodes of atrial fibrillation. So that’s a risk factor that is becoming more recognized and the data is starting to become out more as a potential risk factor for developing atrial fibrillation.

In some cases, atrial fibrillation may occur without any known heart disease or heart damage.

Comprehending the fundamental causes of atrial fibrillation is key for preventive measures and treatment. Insight into the heart conditions and medical factors tied to AFib assists individuals and healthcare providers in making informed decisions for superior heart health.

What Causes AFib: Past Heart Conditions

Atrial fibrillation is typically associated with changes or damage to the heart’s tissue and electrical system, usually caused by:

These heart conditions might result in structural changes in the heart, disrupting its normal functioning and possibly leading to atrial fibrillation. Pinpointing and managing these underlying heart issues are vital to the prevention and treatment of AFib.

What Causes AFib: Other Medical Factors

Besides heart conditions, other medical factors can contribute to the development of atrial fibrillation. High blood pressure and diabetes, for example, are additional medical factors that may lead to AFib. High blood pressure can strain the heart, resulting in an irregular heartbeat and atrial fibrillation.

Furthermore, several other medical factors can be associated with atrial fibrillation, such as:

• Thyroid problems

• Lung diseases

• Sleep apnea

• Obesity

• Diabetes

• Alcohol and drug abuse

• Family history

• Age

Understanding and managing these factors can help reduce the risk of developing atrial fibrillation.

Lifestyle Triggers of Atrial Fibrillation

Lifestyle factors can act as triggers for atrial fibrillation. Alcohol consumption, caffeine intake, stress, lack of sleep, smoking, obesity, and physical exertion have all been identified as triggers of AFib. Alcohol consumption, for example, can increase the risk of atrial fibrillation, as it can result in dehydration and electrolyte imbalances.

Caffeine consumption, on the other hand, can lead to an increased risk of AFib due to its effects on heart rate and blood pressure, in some people. Other factors that can elevate the risk of atrial fibrillation include:

• Stress

• Lack of sleep

• Smoking

• Obesity

Recognizing and controlling these lifestyle triggers can aid in preventing or regulating atrial fibrillation.

Causes of AFib: Managing Stress

Stress has been identified as a potential trigger for atrial fibrillation, as it can cause an elevation in heart rate and blood pressure, leading to an irregular heartbeat.
