Creavo has developed diagnostic technology using magnetocardiography (MCG) to measure fluctuations in magnetic fields caused by heart activity. The first product resulting from the work will help physicians in A&E departments rule out significant heart disease in patients presenting with chest pains. This represents a considerable portion of A&E patients but existing protocols take up to 12 hours to resolve the issue which causes stress to them, and also imposes significant costs on the NHS.
