Dr Walker graduated from the University of Birmingham, and undertook clinical training in cardiology at St.Thomas’ Hospital, London, and John Radcliffe Hospital, Oxford. He then took up the post of Cardiologist and Physician at University College, and the Middlesex Hospitals, London, in 1987.
His research lead to an MD in 1983, and involved studying the mechanical performance of the heart. This interest in laboratory research led him to set up the Hatter Cardiovascular Institute at UCH in 1989. This institute moved into its current premises in 2006. The building fused clinical activity with state-of-the-art laboratory research, so that the entire ground floor was designed to house the Cardiovascular Health and Rehabilitation services, including a spacious gymnasium. As a consequence, he became Treasurer and then President of the British Association of Cardiovascular Rehabilitation, between 2001 to 2006, as well as a Council member of the British Cardiovascular Society.
His involvement with patients with inherited haemoglobin diseases has led to a programme of clinical research and service provision with the world’s first cardiology clinic set up specifically to provide a diagnostic and treatment service for young patients with these challenging conditions.
Dr Walker specialises in general and interventional cardiology, cardiovascular health and rehabilitation, cardiovascular complications, and haemoglobin disorders.
