New tech helps prevent children from sudden cardiac death

Each week in the UK at least 12 people under 35 die of undiagnosed heart conditions.

disease known as Hypertrophic Cardiomyopathy, which causes a thickening of the heart muscle, is responsible for most of these tragedies.

Up until now, diagnosis has only been possible by screening the heart itself. Now researchers have created a blood test that not only detects the condition, but determines how likely it is to prove fatal.
