Does atrial fibrillation run in families?
Answer Section
It can. Atrial fibrillation (AFib) is a heart rhythm disorder. It causes irregular and chaotic heartbeats that can lead to stroke. AFib can be passed down through families. That means it can be inherited. When this happens, the condition is called familial atrial fibrillation.
If you have familial AFib, you may get the irregular heartbeat earlier in life than do those with AFib who don't have a family history of the condition.
Usually, common heart disease risk factors lead to atrial fibrillation. Things that make you more likely to get AFib are:
- Diabetes.
- Heart valve disease.
- Heavy alcohol use.
- High blood pressure.
- Male sex assigned at birth.
- Obesity.
In some people, a risk factor can't be found. But researchers have linked some gene changes to the condition.
Understanding the genetics of atrial fibrillation is important. It could lead to tests to better identify and treat those at risk of AFib. But more research is needed.
If someone in your family has AFib and you're concerned about your risk, talk with a healthcare professional. A simple test called an electrocardiogram (ECG or EKG) can be done to check your heartbeat.
You might not be able to prevent familial atrial fibrillation. But lifestyle changes can help keep your heart healthy. Try these tips:
- Eat a healthy diet.
- Get regular exercise.
- Don't smoke.
- Manage weight.
- Limit alcohol.
- Get 7 to 9 hours of sleep daily.
