Certain factors may increase your risk of developing atrial fibrillation (AF). These include:
The older you are, the greater your risk of developing AF.
Anyone with heart disease — such as heart valve problems, congenital heart disease, congestive heart failure, coronary artery disease, or a history of heart attack or heart surgery — has an increased risk of AF.
High blood pressure
Having high blood pressure, especially if it's not well-controlled with lifestyle changes or medications, can increase your risk of AF.
Other chronic conditions
People with certain chronic conditions such as thyroid problems, sleep apnea, metabolic syndrome, diabetes, chronic kidney disease or lung disease have an increased risk of AF.
For some people, drinking alcohol can trigger an episode of AF. Binge drinking may put you at an even higher risk.
People who are obese are at higher risk of developing AF.
An increased risk of AF is present in some families.
