The new experiment, led by Dr Mike Curtis, School of Cardiovascular Medicine & Sciences, used a heart attack model in rats to test the effectiveness of the newly synthesised compound OCT2013. Many of the 100,000 deaths from heart attacks that happen each year in the UK occur before the ambulance can arrive on the scene. This is due to ischaemia – the heart’s muscle not receiving enough blood due to a block in a coronary artery.
