Dr Joao Martins

Dr Joao Martins is a consultant cardiologist in Brighton and central London who specialises in chest pain, shortness of breath and palpitations, alongside valve disease (heart murmurs), TAVI, heart failure, hypercholesteromia and hypertension. He privately practises at Nuffield Health Brighton Hospital, the National Heart Clinic on Harley Street, and Royal Sussex County Hospital, part of University Hospitals Sussex NHS Foundation Trust.

Dr Martins specialises in interventional and structural cardiology, providing comprehensive, evidence-based care for general and complex cardiovascular conditions. He focuses on minimally invasive, state-of-the-art techniques for treating valvular and coronary disease. Patients benefit from his subspecialist skills in percutaneous valve repair, transcatheter coronary interventions, mitral and tricuspid edge-to-edge repair (TEER), and patent foramen ovale (PFO) closure.

Dr Martins maintains an active research programme centred on device-based therapies and clinical trials aimed at improving outcomes for patients with advanced coronary and structural heart disease. His doctoral research at Harvard Medical School examined translational stem-cell therapy for cardiac repair. He has authored multiple publications in peer-reviewed journals and presented at leading international conferences.

His academic excellence has been recognised through several awards, including the Jay N. Cohn New Investigator Award (Heart Failure Society of America, 2011), the Delta Award in Ischemic Cardiomyopathy (Portuguese Society of Cardiology, 2008), and the Zondek Prize (European Students Conference, 2006).

Dr Martins holds membership in several professional organisations including the Royal College of Physicians, European Society of Cardiology, and British Cardiovascular Intervention Society.
