Atrial fibrillation (AF) is a type of irregular heartbeat that can cause blood clots to form in your heart. Having atrial fibrillation increases your risk of stroke by five times.

Information about atrial fibrillation for healthcare and other professionals. We have a number of resources available including guides and factsheets.

Share these social media posts and images to raise awareness of atrial fibrillation (AF) for Stroke Prevention Day 2023.

Stroke Prevention Day 2023 took place 12 January. This year we’re helping people to check for atrial fibrillation, which lots of people live with and don’t even know it. ​

Techniques to predict - and in future prevent - brain haemorrhage in people treated with warfarin after stroke caused by atrial fibrillation

We have compiled the state of atrial fibrillation care for each CCG in England. How is AF care in your CCG?

The CROMIS-2 study investigated whether signs of small brain bleeds on routine brain scans can help us understand which ischaemic stroke patients with atrial fibrillation are at increased risk of a bleed in the brain when on anticoagulant ‘blood thinning’ drugs.

Dr Alan Cameron and the ASPIRE team are developing a way to predict who’s at risk of atrial fibrillation so that they can be offered screening and treatment to help prevent stroke.

This study will investigate whether early initiation of direct anticoagulant drugs will be as safe as later initiation in stroke patients with an abnormal heart rhythm (atrial fibrillation). It will also investigate whether early initiation could lead to fewer recurrent strokes.

A Post-Stroke Review identifies the unmet needs of stroke survivors and their carers, which our coordinators then address. They also carry out checks to highlight unidentified high blood pressure or Atrial Fibrillation.
