With cardiovascular disease remaining the UK’s biggest killer—claiming 480 lives every day—there is a clear gap between the scale of the problem and public understanding of heart health. To address this, the Relations Group delivered a UK-wide broadcast campaign timed around World Heart Day 2025, using a powerful spokesperson and real-life case study approach to humanise the statistics. By spotlighting the fact that twice as many Brits live with heart disease as cancer and Alzheimer’s combined, and securing coverage around a compelling story of a marathon world-record holder living with a heart condition and training to “go again,” we brought urgency, relevance, and hope to the conversation. World Heart Day provided a timely national hook to cut through the noise, driving awareness, education, and media engagement around heart health at scale.
