Testing a new ablation method to treat atrial fibrillationImperial College London | Professor Prapa Kanagaratnam
Dr Prapa Kanagaratnam and his team at Imperial College London are working out if a new ablation protocol to treat atrial fibrillation (AF) can help people avoid the need to attend hospital. AF is the most common type of abnormal heart r...

Is a tiny molecule a big culprit in atrial fibrillation?University of Oxford | Dr Svetlana Reilly
BHF Intermediate Basic Science Research Fellow Dr Svetlana Reilly is studying how a small molecule called microRNA 31 (miR31) causes heart muscle changes in atrial fibrillation. Arrhythmias occur when the heart’s normal rhythm becomes d...

The processes involved in the heart’s response to stressImperial College London | Professor Dr Thomas Brand
‘Popeye’ proteins are a newly discovered group of molecules in the outer surface of the cell, the cell membrane. They play a role in helping the heart rate to change in response to stress by interacting with other proteins (channels and pum...

Bolstering the heart’s defences against chemotherapy and diabetesUniversity of Leeds | Professor Derek S Steele
In the cells of our body, day-to-day processes cause the creation of ‘reactive oxygen species’ (ROS) – toxic molecules that can cause damage to our cells. In the heart, excessive ROS production can cause dangerous irregular heart rhythms. ...

Understanding and modelling the heart’s wiring systemUniversity of Manchester | Professor Mark R Boyett
The heart beat is produced by regular electrical pulses generated by the heart’s own wiring system. Changes during disease can lead to problems with the heart’s wiring system that causing erratic heart beats (arrhythmias) and in very seriou...

Invisible insulin resistance linked to increased risk of sudden death
Years before developing diabetes, people with insulin resistance could be more likely to develop abnormal heart rhythms, which may put them at greater risk of sudden death, according to research we've funded and presented today at the British Cardiovascular Society conference.

Adrenaline and atrial fibrillationUniversity of Glasgow | Dr Antony Workman
Dr Anthony Workman and his team at the University of Glasgow are studying atrial fibrillation - or AF - a common abnormal heart rhythm where the heart’s upper chambers, the atria, beat irregularly. People with atrial fibrillation are more l...
