Atrial fibrillation, also called AFib or AF, is the most common irregular heart rhythm in the United States where 2.7 to 6.1 million Americans are living with this dangerous condition. Here’s AFib explained, the risks, and how this one food affects these abnormal heart beats.

What is Atrial Fibrillation?
Atrial fibrillation (AFib) is an irregular heart rhythm caused by abnormal electrical signals in the upper chambers of the heart.
AFib is on the rise because the older you are, the greater the risk of developing AFib. Finding effective ways to prevent AFib and identify treatments for AFib is a public health priority.
Typically someone one with AFib has to take a blood-thinner to prevent blood clots from forming and reduce stroke risk. Blood thinners can have dangerous side effects, such as severe bleeding, coughing up blood, bruising without an injury, and dizziness.
High Blood Pressure Link
If you have high blood pressure, AFib needs to be on your radar. People with high blood pressure (which usually occurs with advancing age) accounts for 14% to 22% of AFib cases.
Health Effects from Atrial Fibrillation (AFib)
Atrial fibrillation is dangerous. It is a risk factor for:
- Stroke — 4 to 5 times higher risk compared with people without AFib. Strokes caused by AFib complications tend to be more severe than strokes with other underlying causes.
- Heart failure — AFib decreases coronary blood flow.
- Cognitive decline and dementia — One gallon of blood goes through your brain every four minutes. If blood flow is impaired such as from AFib, brain function suffers. Persistent AFib decreases blood flow to the brain.
- Death

AFib Symptoms
Some people don’t have any symptoms, but many experience one or more of the following:
-
- Irregular heart beat (feels like your heart is skipping beats)
- Heart palpitations (racing, fluttering, or pounding)
- Lightheadedness
- Extreme fatigue / discomfort
- Shortness of breath
- Chest pain / sweating (mimicking a heart attack)
