Scientists have worked out how to use a brain scanner to diagnose people with hypertrophic cardiomyopathy. Scientists can use MRI scanners to take pictures of the heart muscle fibres and spot signs of deadly hypertrophic cardiomyopathy. In the past, studying these heart fibres to check for abnormalities could only be done after a patient had already died. If the scan reveals someone has the tell-tale disarray in their heart muscle fibres, doctors could put in a defibrillator. It can cause the heart muscle to become stiff, which means your left ventricle doesn't fill as easily as normal and less blood is then pumped out.
