British-based scientists have produced an antibody that reduces by more than 60 per cent the physical scarring of the heart and brain after an attack. The "milestone achievement" could also be used to stop the body attacking organ transplants.
Professor Wilhelm Schwaeble, who carried out the work at Leicester University, said that it could potentially be the "biggest breakthrough ever" in the treatment of two of the biggest killers in Britain. Heart attacks and strokes are caused by blood flow being blocked by a clot or a bleed, starving parts of the body further down stream of oxygen.
But most of the permanent damage is caused later – when circulation is eventually restored – and a "default of nature" which means the body's own defences attack the oxygen starved cells.
This effect, which kicks in around nine to 12 hours after the attack or stroke, causes massive inflammation and more than 80 per cent of the permanent damage. It is this that often leads to death and massive reduction in the quality of life of stroke and heart attack survivors.
Now the researchers at the University of Leicester have come up with an injection which they claim effectively stops the body attacking the oxygen starved cells.
This allows them to start to oxygenate normally and the permanent damage is reduced significantly. The research has been tested on mice and more advanced mammals and has also been shown to work on human blood in the laboratory.
Human trials are expected to begin within two years.
