What Increases Your Risk?

Several factors make AFib more likely.

  • Older age, although it can happen at any age
  • Conditions that place added strain on the heart including high blood pressure, a previous heart attack, heart surgery, valve disease, heart failure
  • Other illnesses such as obesity, sleep apnea or hyperthyroidism
  • Family history   
  • Drinking too much alcohol (routinely having 3 or more drinks a day or binge drinking) 

Episodes of AFib are often triggered by certain activities. These may include: 

  • Heavy alcohol use
  • Too much caffeine or other stimulants
  • Periods of severe stress
  • the stress of the body fighting infection
  • the stress of recent surgery

Pay attention to what might make symptoms of AFib worse, so that you can share this information with your health care team.
