Risk factors
By Mayo Clinic staffRisk factors for atrial fibrillation include:
- Age. The older you are, the greater your risk of developing atrial fibrillation.
- Heart disease. Anyone with heart disease, including valve problems, history of heart attack and heart surgery, has an increased risk of atrial fibrillation.
- High blood pressure. Having high blood pressure, especially if it's not well controlled with lifestyle changes or medications, can increase your risk of atrial fibrillation.
- Other chronic conditions. People with thyroid problems, sleep apnea and other medical problems have an increased risk of atrial fibrillation.
- Drinking alcohol. For some people, drinking alcohol can trigger an episode of atrial fibrillation. Binge drinking — having five drinks in two hours for men, or four drinks for women — may put you at higher risk.
- Family history. An increased risk of atrial fibrillation runs in some families.
