How Can Atrial Fibrillation Be Prevented?

You may be able to prevent atrial fibrillation (AF) by following a healthy lifestyle and taking steps to lower your risk of heart disease. These steps include:

• Following a heart healthy diet that's low in saturated fat, trans fat, and cholesterol. A healthy diet includes a variety of whole grains, fruits, and vegetables daily.
• Not smoking.
• Getting physical activity regularly.
• Maintaining a healthy weight.

If you have heart disease or other AF risk factors, work with your doctor to control your condition and lower your risk of complications, such as AF.

In addition to following the healthy lifestyle steps above, which also can help control heart disease, your doctor may advise you to take one or more of the following steps:

• Follow the DASH eating plan to help lower your blood pressure.
• Keep your cholesterol and triglycerides at healthy levels with dietary changes and/or medicines.
• Limit or avoid alcohol.
• Control your blood glucose (blood sugar) levels if you have diabetes.
• Get ongoing medical care and take your medicines as prescribed.
