An Interventional Cardiologist undertaking research into the prevention of cardiovascular disease. Clinical - academic aims are to bridge the interventional and preventive approaches to cardiovascular disease which are often viewed as distinct.

Trained in Medicine at Oxford University and then Imperial College (St Mary's Hospital) London, graduating in 1993 with a BA and MBBS and later MRCP in 1996, following junior medical posts in London and Oxford. After embarking on a Residency in radiology at New York University, USA, switched discipline to cardiology, training as a specialist registrar in cardiology and general medicine in the Wessex region (1999-2005) and completing an MD degree (London, 2004) in parallel with clinical training.

Following a year as a Fellow in Interventional Cardiology at Southampton University Hospital, appointed Senior Lecturer and Honorary Consultant Cardiologist at Barts and the London School of Medicine and Dentistry in 2006, became Reader in 2010, and Professor of Cardiology in 2014.


Chief Investigator for several randomized clinical trials, including:

  • Preventive Angioplasty in Myocardial Infarction (PRAMI) Trial: a multicentre single blind randomised trial assessing the value of coronary angioplasty in preventing future coronary heart disease events among patients receiving angioplasty to treat an acute myocardial infarction. The two-year results indicate a 2/3rds reduction in cardiac death, non-fatal myocardial infarction and refractory angina in patients receiving preventive angioplasty.
  • Child Parent Screening Study: a 10,000 person MRC-funded national study to test the accuracy of a novel child-parent population screening strategy that screens children and their parents within the same programme, by combining cholesterol measurement with routine childhood immunization.
  • Polypill Prevention Trial: together with colleagues developed a polypill for the prevention of ischaemic heart disease and stroke, and now leading a UK trial testing this in people over the age of 50.
  • INTERACT Trial: a randomized trial assessing the value of automated text messaging on adherence to blood pressure and cholesterol lowering medications in primary care.
  • Prevention of Aortic Stenosis Pilot Trial: MRC-funded randomised cross-over trial of serum phosphate reduction using phosphate binding medication as a potential means of preventing the progression of aortic stenosis.

Principal source of Funding: Medical Research Council

  • Child-parent screening for familial hypercholesterolaemia
  • Preventive Angioplasty in myocardial infarction
  • Polypill for the prevention of cardiovascular disease
  • Medication Adherence strategies
  • Prevention of Aortic stenosis
