Atrial fibrillation (also known as AF or AFib) is the most common type of arrhythmia (irregular heartbeat or heart rhythm). If not properly managed or treated, atrial fibrillation can have serious complications.

Atrial fibrillation increases your risk for stroke, heart failure, and being hospitalized. Learn more about these complications here.

The good news is that majority of people with AF live active, healthy lives with treatment and healthy lifestyle choices.

Here's what you can do to prevent atrial fibrillation complications:

  • Live a healthy lifestyle that includes eating healthy, exercising regularly, and reducing stress. Learn more in "What can I do?"
  • Take your medications exactly as prescribed. If you have difficulty taking your medication or are concerned about side effects, talk to your doctor or pharmacist. It is important to take your medications as prescribed because they help relieve your symptoms, improve your quality of life, and reduce your risk of long-term complications, such as stroke.
  • Visit your doctor regularly. Your doctor needs to monitor your progress, see how well the treatment is working, and help you maintain your quality of life.
