Malcom Walker BSc, MBChB, MD, FRCP

Dr.Malcolm is a Consultant Cardiologist working at University College (UCH) and the Heart Hospitals, London. Cardiology is the branch of medicine dealing with disorders of the heart and blood vessels.Dr Walker’s clinical work involves providing out-patient and in-patient consultations including interventional treatments to adult patients with established heart disease, or at risk of developing heart disease.

His research interests are General adult clinical cardiology, including coronary intervention and pacemaker therapy, Cardiovascular Rehabilitation and Prevention, Cardiovascular complications of inherited diseases of haemoglobin, specifically the thalassaemia syndromes and sickle cell disease.
