RESEARCH
Understanding heart scarring in atrial fibrillationQueen's University Belfast | Dr David Simpson
Atrial fibrillation (AF) – abnormal beating of the heart – often occurs because scar tissue has formed in the heart. This process is called fibrosis. The aim of this project is to understand more about the cells that cause fibrosis, to deve...

Could MKK7 be a new treatment target to reduce heart damage after a heart attack?University of Manchester | Dr Xin Wang
Manchester researchers are studying a protein in the heart that they believe could have protective properties for heart cells. During a heart attack, a portion of the heart is starved of its blood supply. This kills or injures a large numb...

Understanding how released histones exert their toxic effects on the heartUniversity of Leeds | Professor Derek S Steele
Histones are a family of proteins which provide structural support to DNA. In healthy cells, histones (along with DNA) are found in the nucleus (the command centre of the cell). When cells are damaged and die e.g. due to a lack of oxygen...

Atrial fibrillation – what makes the rhythm disorder so hard to treat?University of Manchester | Dr Gwilym Morris
A group of researchers in Manchester, led by Dr Gwilym Morris are working to understand why a common heart rhythm problem resists treatment in some patients. Atrial fibrillation (AF) is the most common heart rhythm disorder, affecting mor...

Spotting the silent heart rhythm disorders to prevent stroke and dementiaUniversity of Oxford | Professor Barbara Casadei
Atrial fibrillation (AF) is the most common irregular heart rhythm. It is linked to increased risk of stroke and heart attacks. Short episodes of AF are relatively common, particularly in the elderly, and tend to go unnoticed. But it’s poss...

Revealing how heart cells detect stretchUniversity of Leeds | Dr Sarah C Calaghan
The ability of heart cells to sense stretching is essential for normal heart function, and allows the heart to pump more blood when it is needed, like during exercise. When cells are stretched too much and too often, the heart can change an...

Searching for a heart failure drug that targets how the heart muscle contractsKing's College London | Dr Thomas Kampourakis
Researchers at King’s College are on the hunt for a better, kinder, treatment for heart failure. This is urgently needed. Heart failure affects hundreds of thousands of people in the UK today. It is a progressive condition that can be debi...

Why are failing hearts more susceptible to atrial fibrillation?University of Manchester | Dr Katharine Dibb
BHF-funded researchers in Manchester are investigating what underlies the link between heart failure and atrial fibrillation. People with heart failure often develop a common heart rhythm problem, called atrial fibrillation, which signif...

Do chemical changes to DNA cause scarring in the heart during coronary heart disease?Queen's University Belfast | Dr Chris Watson
In coronary heart disease, the small vessels that deliver blood supply to the heart are narrowed by the build-up of fatty plaques in the artery wall. These can rupture and cause a blood clot that can completely block the artery. The consequ...

Predicting the best way to reset the heart’s rhythmImperial College London | Dr Zachary Whinnett
People with abnormal heart rhythms are sometimes treated with a method called ‘pacing’ which uses small electrical pulses to reset their heartbeat. Scientists have recently discovered a new method for resetting the heartbeat called His-paci...
