Atrial fibrillation is a commonly diagnosed heart rhythm problem. It involves electrical impulses spontaneously firing at different places in the top chambers of the heart causing the heart to twitch or ‘fibrillate’.

Atrial fibrillation is estimated to affect more than 45 million people worldwide, including 1.6 million people in the UK.

Unfortunately having atrial fibrillation is a risk factor for strokes. Some people may have AF without noticing any symptoms whereas other patients may experience a range of symptoms including palpitations.

Evidence suggests appropriate use of oral anticoagulants such as warfarin or apixaban can significantly reduce the risk of stroke however currently there is an underutilization of anticoagulation in patients at high risk of stroke.

If you have atrial fibrillation and currently not taking any medication for it, you might be eligible for a clinical trial.

Eligibility Criteria

• Male or female between ages 65-74
• Diagnosis of atrial fibrillation or atrial flutter
• Not taking oral anticoagulation medication
