A Guide for Patients and Caregivers

If you or someone you love has been diagnosed with atrial fibrillation (Afib), you’re not alone—and you’re not powerless. Afib is a common heart rhythm disorder, but with the right care, lifestyle choices, and support, you can live a full and active life.

Let’s explore how to manage Afib, keep your heart healthy, and know when it’s time to talk to your doctor about more advanced treatment options like surgery.

What Is Afib?

Afib is an irregular heartbeat that starts in the upper chambers of the heart (the atria). Instead of beating in a steady rhythm, the heart flutters or quivers, which can lead to blood clots, stroke, heart failure, and other complications if left untreated.

Everyday Tips for a Healthier Heart with Afib

Managing Afib starts with taking care of your whole heart. Here are some simple but powerful steps you can take:

• Take your medications as prescribed. These may include blood thinners, beta blockers or rhythm control drugs.
• Eat heart smart. Focus on fruits, vegetables, proteins and healthy fats. Limit sugar and processed foods.
• Stay active. Exercise like weightlifting, walking, and swimming can help your heart stay strong. Always check with your doctor before starting a new routine.
• Limit alcohol and caffeine. These can trigger Afib episodes in some people.
• Manage stress. Deep breathing, meditation, or talking to a counselor can help reduce stress, which may lower your risk of Afib episodes.
• Quit smoking. If you smoke, ask your doctor for help quitting—it’s one of the best things you can do for your heart.
   

When to Call Your Doctor

Afib symptoms can vary, but it’s important to know when to seek medical advice. Call your doctor if you experience:

• Unusual fatigue or weakness
• A racing, fluttering or pounding heartbeat
• Shortness of breath
• Dizziness or fainting
• Chest pain or pressure

Even if your symptoms seem mild, don’t ignore them. Afib can increase your risk of stroke by up to five times. Early treatment can make a big difference.

When Is Surgery an Option?

For some people, medications and lifestyle changes aren’t enough to control Afib. If you’re already scheduled for heart surgery—like a valve repair or bypass—your surgeon may be able to treat your Afib at the same time through a procedure called surgical ablation.

This procedure uses heat or cold to create scar tissue in the heart, blocking the faulty electrical signals that cause Afib. It can also include closing off a small pouch in the heart called the left atrial appendage, which is a common source of blood clots that can cause a stroke in Afib patients.

Talk to your cardiologist or surgeon about whether this option is right for you.

You’re Not Alone

Living with Afib can feel overwhelming, but you don’t have to face it alone. With the right care team, a healthy lifestyle, and support from loved ones, you can take control of your heart health.
If you’re preparing for heart surgery or struggling with Afib symptoms, don’t wait—talk to your doctor.  Afib is a progressive disease, which means it gets worse over time. The sooner you act, the better your chances of staying strong and living well.
