Improving risk assessments for people with inherited heart conditionsImperial College London | Dr Fu Siong Ng
Dr Fu Siong Ng is studying why some people with an inherited heart condition are at greater risk of dying suddenly than others. Despite advances in genetic research, it is a challenge for doctors to predict which people with inherited h...

Developing a realistic computer model of abnormal heart rhythmsImperial College London | Dr Emmanuel Dupont
Dr Emmanuel Dupont and his team at Imperial College London are testing a new computer simulation, which would allow researchers to study abnormal heart rhythms. To beat regularly, the heart contracts in response to complex electrical ci...

How cardiac hypertrophy leads to heart rhythm disturbancesUniversity of Surrey | Dr Rita Jabr
Dr Rita Jabr and Professor Christopher Fry from the University of Surrey will be investigating the potentially dangerous disturbances to heart rhythm that can occur as a result of cardiac hypertrophy. Cardiac hypertrophy is enlargement of t...

Studying the proteins that control heart rhythmUniversity of Oxford | Professor Ming Lei
Tiny pores, or ion channels on the surface of heart muscle cells open and close to let electrically charged sodium, calcium and potassium ions flow into and out of heart cells and generate the electrical signal that spreads from the top of ...

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. ...

Deciphering the fine structure of atrial cells in healthy hearts, and in those with heart failure, for clues to atrial fibrillationUniversity of Manchester | Dr Katharine Dibb
Atrial fibrillation (AF) is the most common form of irregular heart rhythm, and people with heart failure are more at risk of the condition. AF affects the atria - the top two heart chambers – where disturbed electrical signals prevent rhyt...

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...

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...
