Professor John E. Deanfield CBE FMedSci is Professor of Cardiology at University College London (UCL). He trained in medicine at the University of Cambridge and The Middlesex Hospital, London, followed by postgraduate training in both adult and paediatric cardiology.

Professor Deanfield is internationally recognised for his pioneering work in cardiovascular prevention and the lifetime management of cardiovascular risk. His research has transformed understanding of how obesity, dyslipidaemia, diabetes, smoking and other cardiometabolic risk factors influence vascular health across the life course. He has championed the concept of “investing in your arteries”, emphasising the long-term benefits of early and sustained risk factor management.

He founded and directed the UK National Institute for Cardiovascular Outcomes Research (NICOR), creating one of the world’s largest cardiovascular outcomes databases to improve quality of care, support innovation and facilitate large-scale real-world clinical research. He has played a leading role in the development of national and international cardiovascular prevention strategies, including chairing the Joint British Societies (JBS3) Guidelines for Cardiovascular Disease Prevention.

From 2023 to 2024, Professor Deanfield served as the UK Government’s Champion for Personalised Prevention, helping to shape policy at the intersection of health, prevention and economic growth. He continues to work extensively with academic, healthcare and life sciences partners to accelerate the evaluation and implementation of innovative therapies, particularly in the fields of cardiovascular-kidney-metabolic (CKM) disease and obesity.

He has published more than 590 peer-reviewed articles, with over 200,000 citations, and is consistently ranked among the world’s leading clinical scientists. In recognition of his contributions to cardiovascular medicine and disease prevention, he was appointed Commander of the Order of the British Empire (CBE) and is a Fellow of the Academy of Medical Sciences (FMedSci).
