Professor Mark Ledwidge, Co-Founder and Director of the Heartbeat Trust talks about his research and how Whole Genome Sequencing is helping to unravel some of the mysteries surrounding heart failure. He discusses the challenges around the sub-type of heart failure known as Heart Failure with Preserved Ejection Fraction where the pump itself is working correctly but the heart is unable to fill adequately to provide enough blood for the body’s needs. We also hear from Mark’s father, Tom Ledwidge who, at 81 leads a very healthy and active life despite his own heart issues. Tom advocates strongly for clinical research and is a research participant himself.
