Dr Anthony Barron

Consultant cardiologist
Specialises in heart failure and cardiac imaging, mainly focusing on nuclear cardiology and echocardiography.

Dr Anthony Barron is a consultant cardiologist at Royal Brompton and Harefield hospitals. 

He graduated in 2003 from St. Mary’s Hospital, Imperial College London, and after several junior doctor posts he went on to become a cardiology registrar in 2007 where he rotated between North-West London Hospitals. Dr Barron began his PHD in 2010 and after its completion in 2013became a registrar at Harefield hospital in transplant cardiology.   

Dr Barron then ventured into imaging and in 2016 obtained a CCT in cardiology, sub-specialising in heart failure and echocardiography. This led to Dr Barron’s position as a locum and then a substantive consultant in 2019 at Harefield hospital.  

Clinical expertise

Dr Anthony Barron is a heart failure specialist and manages patients with medication and helps treat symptoms of heart failure, such as, fatigue, ankle swelling and breathlessness in patients with abnormal hearts. He also treats and investigates most cardiac conditions, treating patients with intravenous iron where their heart failure is the cause of iron deficiency.   

Dr Barron has a specialist interest in valve disease and how this impacts on the heart. He performs all echocardiographic studies including transoesophageal echocardiogram (TOE), nuclear cardiologySPECT myocardial perfusion imaging, transthoracic echocardiogram (TTE) and stress and contrast.

Research interests

Dr Anthony Barron has had multiple parts of his PhD published.  This research study was based on the value of cardiopulmonary exercise testing in patients with heart failure.  He is currently researching valvular disease and how it affects the heart, and on the correct role of imaging. He is also a co-principle investigator on a research trial, called Ironman, looking at intravenous iron in heart failure. 


Dr Anthony Barron has been involved in many publications, including: 

  • The effect of duration of follow-up and presence of competing risk on lifespan-gain from implantable cardioverter defibrillator therapy: who benefits the most?  
  • Large-scale genome-wide analysis identifies genetic variants associated with cardiac structure and function. 
  • Is it time to change? Portable echocardiography demonstrates high prevalence of abnormalities in self-presenting members of a rural community in Kyrgyzstan. 
  • Oxygen uptake efficiency slope and breathing reserve, not anaerobic threshold, discriminate between patients with cardiovascular disease over COPY. 
  • Phase analysis, a novel SPECT technique for left ventricular dyssynchrony: Are degrees and milliseconds interchangeable? 

Dr Anthony Barron is the lead supervisor and educator for the SHO grade and the new Physician Associate, as well as the Royal College Tutor for Medicine at Harefield Hospital.
