Dr Tim Lockie

Consultant Interventional Cardiologist

MBChB, BSc. (First Class Hons), PhD

Dr. Lockie grew up in North London attending University College School in Hampstead, before training in Medicine at Edinburgh University. During this time he also undertook an intercalated BSc. Med. Sci. gaining First Class honours. After graduation with MBChB in 1999, he worked on the professorial medical and surgical wards at the Old Royal Infirmary in Edinburgh before moving to London for his specialist Cardiology training at St Thomas’.
With an interest in ischaemic heart disease and revascularisation he undertook a PhD at KCL, London, winning the Young Investigator Prize at the international SCMR conference in the United States, as well as presenting and publishing his work at other conferences around the world. He then spent a year at the Academic Medical Centre in Amsterdam on a British Heart Foundation training fellowship specialising in advanced stenting and percutaeous coronary interventions (PCI). He then completed his PCI training back at St. Thomas’ under the supervision of Prof. Simon Redwood who is the current president of the British Coronary Intervention Society (BCIS). He now works as a consultant interventional cardiologist at the Royal Free London NHS Foundation Trust.
Dr. Lockie specialises in complex PCI, primary angioplasty for acute heart attacks, intravascular imaging and coronary physiology and has an ongoing interest in cardiovascular research being the principle site investigator for several large, multinational studies. He is the clinical lead for the cardiac catheterisation labs at the Royal Free and in developing local guidelines. He also has responsibility in education and maintaining the institutional databases for heart attacks and PCI. He sits on the national advisory board for the British Cardiac Society, representing the North Central London region. He regularly teaches and lectures at conferences and seminars, including the international faculty of the European Society of Cardiology.
Dr. Lockie believes in a multidisciplinary and holistic approach to the treatment of patients with cardiac problems involving the latest and most sophisticated investigations and techniques, but also careful clinical assessment, always placing the patient’s needs and concerns at the centre of any management plan.
