About me

Attended the University of Birmingham Medical School, graduating with honours in pre-clinical sciences. Cardiology training at St. Thomas’ Hospital, London and at the University of Oxford.
In 1987 appointed as consultant cardiologist at University College Hospital London.
Founded the Hatter Cardiovascular Institute at UCL in 1990.
Clinical commitments include the provision of cardiology services and interventional treatments, such as angioplasty and stents, to adult patients. Between 1997 and 2001 was Clinical Director of Cardiac Services, at the time UCH purchased the National Heart Hospital in London. The Heart Hospital and UCH regularly are acknowledged to be amongst the top 3 hospitals in the UK and UCL within the top 4 universities in the world.
Developed a dedicated cardiovascular facility for patients with inherited diseases of the blood, specifically thalassaemia, from which researches resulted in the now accepted non-invasive MRI methodology of measuring myocardial iron content, the cMR T2*. These efforts have been credited with helping to change the outlook for thalassaemia, with a recorded large fall in mortality in the last decade. Scientific and clinical cardiovascular advisor to patient groups and international bodies promoting the care of patients with inherited diseases of haemoglobin, (UKTS and TIF).
Established cardiac rehabilitation services at UCH and the Middlesex Hospitals in 1989 and continue to be the consultant lead for the Cardiovascular Health & Rehabilitation Service at UCLH, an acknowledged leader in the field of cardiovascular rehabilitation: pioneering novel self-management programmes for patients with many disparate conditions, who face cardiovascular risks or complications. These include bariatric patients, cancer patients and primary care patients at risk. Previous President of the British Association for Cardiovascular Prevention and Rehabilitation.
