Brian Clapp attended medical school at Cambridge University and University College London before completing his general medical training in teaching hospitals around London.
Using a British Heart Foundation Fellowship he was awarded a PhD from the University of London into the links between inflammation and acute cardiac events; a continued active research interest.
He completed his specialist training in cardiology at the Heart and London Chest Hospitals, with a particular emphasis on coronary and structural intervention.
In 2005 Brian was appointed consultant cardiologist and honorary senior lecturer at Guy's and St Thomas' NHS Foundation Trust.
Brian provides a clinical service in general cardiology and interventional and structural cardiology and has expertise in all areas of coronary intervention (angioplasty).
In addition he has a specialist interest in the interaction between diving medicine and cardiology (and is on the Health and Safety Executive register of secondary care specialists with an interest in diving medicine). As well as his general cardiology clinics he runs a weekly specialist clinic specifically for this patient group.
