Dr Jonathan Byrne has been a Consultant Cardiologist at King’s College Hospital since 2008. Dr Byrne completed his undergraduate medical training in Bristol and then continued general professional medical training in the South East of England and London. He was awarded a PhD in the academic department of Cardiology at King’s College Hospital in 2004.

He completed extensive training in interventional cardiology at King’s College Hospital from 2004 and continued this along with transoesophageal echocardiography and cardiac CT scanning training on Vancouver Island, Canada in 2006 as an international fellow.

Alongside a wealth of general cardiology experience including the assessment and treatment of coronary and valvular heart disease and risk stratification he also treats hypertension and general heart rhythm disturbances, patients with angina, heart failure and high blood pressure.

Dr Byrne is an interventional cardiologist who specialises in the treatment of coronary artery disease. As well as coronary and structural intervention he also carries out a number of imaging tests for the heart including transoesophageal echocardiography and cardiac CT scanning to screen and assess patients with potential coronary disease.

His research interests have included the molecular mechanisms which underlie the development of left ventricular hypertrophy, and the application of coronary physiology in an interventional setting. His research has also explored the differences and potential advantages of intervention performed from the radial artery.
