What is heart disease, and how can it be tackled?

Today, in partnership with British Heart Foundation (BHF), we take on the world's biggest killer: heart disease. This episode features BHF's Ruth Goss on why this disease kills so many people; Will Watson at the Royal Papworth Hospital in Cambridge on what arterial disease looks like under a microscope; Cathy Shanahan at King's College London on attempts to stop blood vessels from becoming hard and stiff; and BHF's Sonya Babu-Narayan on risk management and heart disease treatment.
