About 300,000 Canadians are living with the after-effects of a stroke, such as paralysis, vision problems, and difficulties with memory and thinking. But this doesn't have to be your story. AFib puts you at a higher risk of stroke, but there are ways you can reduce your stroke risk:
With AFib, your risk of a stroke caused by a blood clot is 3 to 5 times what it would be otherwise. But you can take action to reduce your risk.
Talk to your doctor to get a treatment plan that will help you manage your AFib and reduce your risk of a stroke.
Your treatment plan may involve medications and healthy lifestyle changes. Some people may also need non-drug treatments such as catheter ablation (inserting a long, flexible tube into the heart to deliver controlled electrical pulses, which destroy malfunctioning areas of heart tissue) or electrical cardioversion (using a defibrillator to give controlled electrical pulses to "shock" the heart back into a normal rhythm).
Possible side effects of catheter ablation include pain, bleeding, or infection where the catheter is inserted. It may also cause puncture of the heart or blood clots. Electrical cardioversion side effects may include skin burns, heart rhythm problems, or dislodged blood clots.
It's very important to follow your treatment plan. If you have any questions or concerns, talk to your doctor.

A few simple lifestyle changes can help you live well with AFib and cut your stroke risk:
|Healthy lifestyle change||
What to aim for
|How to make it happen*|
|Eat healthy (good nutrition) as directed by your doctor||
Each day, try to eat:
Don't eat too much sodium. Aim for:
|Exercise as directed by your doctor||Ask your doctor how much activity and what types of exercise are safe for you.||

|Quit smoking as directed by your doctor||Quit smoking and avoid second-hand smoke. If you are a non-smoker, do not start smoking.||
|Tame your stress as directed by your doctor||Understand and control the sources of stress in your life.||
|Have regular medical check-ups as directed by your doctor||Have regular medical check-ups to make sure your AFib is being properly managed and to screen for other conditions that can increase your risk of stroke, such as high blood pressure, high cholesterol, or diabetes.†||

What medications are available, and how are they used?
There are different types of medication for AFib, and each type has a different purpose:
- medications to control heart rhythm: These medications, also called antiarrhythmics, are used to help the heart beat with a more normal rhythm.
- medications to control heart rate: These medications are used to slow down the rapid heart rate seen in people with AFib. This is also called rate control.
- medications to reduce the risk of blood clots (antiplatelet and anticoagulant medications): These medications, also called blood thinners, are used to reduce the risk that a blood clot will form in the heart and travel to the brain, causing a stroke.
Talk to your doctor to learn more about the risks and benefits of these medications.
What are the risks of these medications?
These medications may cause side effects, such as:
- medications to control heart rhythm: heart rhythm changes (sometimes the medications used to control heart rhythm can actually worsen existing arrhythmia or cause a new heart rhythm problem), headache, dizziness, visual disturbances, nausea, diarrhea, or constipation
- medications to control heart rate:
- cardiac glycosides (digoxin): depression, decreased sex drive, enlarged breasts in males, allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives), severe headache, fainting, extreme drowsiness or dizziness, irregular heartbeat, slow heartbeat, vision changes (e.g., yellow-green or blurred vision), hallucinations, abnormal behaviour, deceased appetite, diarrhea, unusual tiredness or weakness, nausea or vomiting
- calcium channel blockers: ankle swelling, flushing, headache, palpitations (typically experienced as a rapid thumping in the chest), dizziness, slow heartbeat, constipation, or heart failure (where the heart has difficulty pumping enough blood to meet the needs of the body)
- beta-blockers: fatigue, dizziness, slow heartbeat, low blood pressure, shortness of breath, decreased capacity for exercise, headache, reduction/loss of libido, depression, or heart failure
- medications to reduce the risk of blood clots: bleeding (e.g., nosebleed, bleeding from the stomach or bowel) or bruising, skin rash, upset stomach, liver disorder, or diarrhea
This is not a complete list of all possible side effects. Talk to your doctor or pharmacist for full information on side effects of a particular medication.How can I get the most from my AFib medication?
- Talk to your doctor to make sure you know how to use your medication. Ask your doctor if there are any special instructions for your medication, such as avoiding certain medications or foods, and whether you need any routine monitoring or testing while you are on the medication.
- Take your medication as recommended by your doctor. If you find that you miss doses of medication or scheduled medical tests, talk to your doctor or pharmacist for help.
- Call your pharmacy for a refill before you run out of medication.
- If you have any questions or concerns about your medication, ask your doctor or pharmacist for help.
- Use the Medication Check-Up tool to make sure you're getting the most out of your medication and see whether it's time to talk to your doctor about your medication.
