Coronary heart disease is the main cause of mortality on the UK. Whilst a number of health promotion strategies encourage and inform individuals of various lifestyle strategies e.g. a low fat, low sugar, high fibre diet, increased exercise etc, coronary heart disease is insidious, often taking years to develop with few or no symptoms. A screening tool whereby cardiac arteries can be assessed non-invasively could allow high volume screening of high-risk patients in a primary care setting. Early identification and treatment of CHD can reduce the risk of future heart attacks and strokes with the associated morbidity. Future associated mortality could also be reduced.  
This project utilises Doppler technology to detect turbulence in the blood flow of arteries suffering from arteriosclerosis, a common precursor to heart attacks. Thus resource implications of prevention rather than cure would be transferred into the primary care setting, not underestimating saving the patient from the physical and psychological trauma of a heart attack.
