Dr Miles Dalby is a consultant cardiologist at Royal Brompton Hospital, where he treats both private and NHS patients.

He studied at St Mary’s Hospital Medical School (now part of Imperial College London), before going on to study for his MD thesis at the Royal Brompton Hospital from 1997-1999. He investigated blood clotting mechanisms, drugs affecting clotting and how these interact with coronary angioplasty and stenting.

Subsequently, he visited the Pitié-Salpêtrière Hospital, Paris and Hôpital Charles-Nicolle, Rouen, as part of his clinical training. He was involved in the first-in-man percutaneous aortic valve replacements with Professor Alain Cribier in Rouen. Dr Dalby received a French postgraduate diploma in interventional cardiology and returned to the UK to complete his training.

Dr Dalby has worked at Royal Brompton and Harefield hospitals as a consultant cardiologist since 2005.

Research interests

Dr Dalby's research interests focus on clinical aspects of coronary intervention, including strategies and logistics of primary angioplasty for acute myocardial infarction.

In addition, he conducts research into the structural and functional analysis of intracoronary thrombus during acute myocardial infarction.

He also leads a research group investigating the biology of intracoronary stents, particularly with regard to the possible risks and benefits of ‘drug-eluting stents’ including high-resolution intracoronary imaging with optical coherence tomography.


Dr Dalby has acted as a reviewer for the:
