Atrial fibrillation (AFib) is an irregular and often rapid heart rate that can increase the risk of stroke, heart failure, and other heart-related complications. The biggest risk of AFib is stroke. AFib increases the risk of stroke by five times because it causes blood to pool in the heart, which can form clots. These clots can then travel to the brain and cause a stroke. About 15 to 20% of all strokes are caused by AFib.
Other risks of AFib include heart failure, atrial flutter, and other arrhythmias. Heart failure is a condition in which the heart is unable to pump enough blood to meet the body's needs. This can lead to shortness of breath, fatigue, and other symptoms. Atrial flutter is an abnormal heart rhythm that can also increase the risk of stroke. Other arrhythmias can also cause symptoms such as palpitations, fatigue, and dizziness.
The best way to reduce the risk of AFib is to manage any underlying conditions that may be causing the irregular heart rhythm. These conditions can include high blood pressure, diabetes, obesity, and sleep apnea. It is also important to maintain a healthy lifestyle by exercising regularly and eating a balanced diet. If AFib is causing symptoms, it is important to speak to your doctor about possible treatments such as medications, lifestyle changes, or surgery.
