Stroke is the leading cause of disability worldwide as well as a serious public health problem. It is the world’s biggest killer along with its close cousin, ischaemic heart disease: together, they were responsible for 15 million deaths around the globe in 2015. The most common type of stroke, ischaemic stroke, occurs when a blood clot disrupts the flow of oxygen and blood to the brain. One risk factor for ischaemic stroke is atrial fibrillation, which is the most commonly undetected type of irregular heartbeat and affects around a million people in the UK. Atrial fibrillation is scarcely discussed in popular media coverage of stroke and heart disease, but new research is demonstrating its significance in figuring out how and why strokes happen.

Today on The Provocateur I talk to Fiona Malone, a PhD candidate in biomedical engineering at the Galway-Mayo Institute of Technology, to discuss the silent killer that is atrial fibrillation. Join us for a lively discussion that covers the ins and outs of atrial fibrillation, the signs and symptoms of ischaemic strokes, Fiona’s research in building 3-D stroke simulations and what (if anything) cows have to do with strokes.
