Professor John Malcolm WALKER BSc. MBChB.  MD. FRCP. Consultant Cardiologist: University College Hospital, London (UCLH). Professor of Cardiology:    Institute of Cardiovascular Science, University College London (UCL). Co-Founder & Clinical Director: The Hatter Cardiovascular Institute (HCI), London. www.drmalcolmwalker.co.uk GMC: 2234618 I qualified in Medicine from the University of Birmingham with honours in pre-clinical medicine and obtained my MD from that institution in 1984. My clinical training in cardiology began at St Thomas’ Hospital London and completed in Oxford before being appointed as Consultant Cardiologist and Physician at University College Hospital London (UCLH) in 1987. I was promoted to Professor of Cardiology in 2020. In 1990 I co-founded with my non-clinical scientist colleague, Dr Derek Yellon, the Hatter Cardiovascular Institute (HCI), utilising a generous donation from a patient. HCI moved into a bespoke building in 2006, where clinical service and laboratory cardiovascular research are housed in close physical proximity. The HCI has an international reputation in laboratory and translational research focusing on myocardial protection, producing >600 publications and over 70 MD and PhDs since its inception. I established the first and still probably the only dedicated cardiology clinic for patients with disorders of haemoglobin, such as thalassaemia and sickle cell. Out of this clinical service arose the interest in iron overload. A collaboration with the Brompton Hospital led to the development of the MRI T2* parameter for non-invasive tissue iron measurement. This has been credited with reducing by 70% the mortality associated with transfusion dependent thelassaemia. Trials of rapid cMRI protocols to improve access to these technologies in less economically developed nations, have been completed in Thailand, India and Peru . In 2016 I helped establish the Cardio-oncology service at UCLH. This is an expanding clinical service and research programme, serving cancer patients with cardiovascular complications. I have published over 120 articles in major scientific journals & have a Scopus H-index of 36.
