About Dr Ozan Demir
Dr Ozan Demir is an award-winning Consultant Cardiologist who specialises in both general and interventional (coronary and structural) cardiology. His areas of expertise include the assessment and treatment of patients with chest pain, coronary artery disease, aortic stenosis, valvular heart disease, high blood pressure (hypertension), high cholesterol, palpitations, and breathlessness, as well as preventive cardiology. He regularly performs advanced interventional procedures, including coronary angioplasty (stent insertion) and transcatheter aortic valve implantation (TAVI). Dr Demir sees private patients in London and Essex, and consults in both English and Turkish.
Dr Demir graduated in medicine from King's College London (Guy's, King's and St Thomas' Medical School) in 2009. He subsequently undertook specialist cardiology training in some of London's leading teaching hospitals, including Hammersmith Hospital and St Thomas' Hospital. Alongside his clinical training, he completed an MSc in Interventional Cardiology at the Vita-Salute San Raffaele University in Milan, and later a PhD in Cardiovascular Medicine and Sciences at King's College London, where his doctoral research focused on the patient-tailored precision management of coronary artery disease.
His career continued with advanced interventional fellowships in both coronary and structural heart disease at internationally recognised centres, including a year-long fellowship in Milan. He went on to hold senior fellowships in London before being appointed as a Consultant Interventional Cardiologist at the Essex Cardiothoracic Centre, where he leads innovative service development projects to improve patient care. He is an Honorary Senior Clinical Lecturer at the Anglia Ruskin School of Medicine.
Dr Demir is widely published, with over 100 peer-reviewed articles in high-impact cardiology journals including the European Heart Journal, JACC and Circulation, and leads clinical research in both coronary and heart valve disease.
Dr Demir is committed to providing patient-centred, evidence-based care, combining his clinical expertise with academic insight to deliver the highest standard of care. He welcomes private patients at his clinics in London and at the Essex Cardiothoracic Centre (Basildon).
