Profile

William Toff is Professor of Cardiology at the University of Leicester with an honorary clinical appointment at the University Hospitals of Leicester NHS Trust. He is Postgraduate Tutor for Cardiovascular Sciences and Chair of the MD Board of Studies.

His clinical and research interests are in cardiac rhythm management, health technology assessment and clinical trials in cardiovascular medicine. He was the founding director of the Leicester Clinical Trials Unit and has led or contributed to many landmark trials in cardiovascular medicine.

He is a member of the national and international standards committees for implanted cardiac devices, has served as a clinical expert advisor for NICE and contributed to numerous health technology appraisals and systematic reviews.

He is the joint founder and director of Heartwize, a registered charity that provides resuscitation skills training in schools and in the wider community.

He has a long-standing interest in aviation medicine and cardiovascular health issues related to air travel.

He is a Fellow of The Royal College of Physicians, The American College of Cardiology, The American Heart Association, The European Society of Cardiology, The Heart Rhythm Society and The Higher Education Academy.

Research

Professor Toff's research is focussed on clinical trials in Cardiovascular medicine. He has led or contributed to landmark trials of pacemaker mode selection, cardiac resynchronisation therapy, the use of implanted and external defibrillators and primary prevention of cardiovascular disease. These have been supported by a range of funders including the National Institute for Health Research (NIHR), the Medical Research Council (MRC), the British Heart Foundation (BHF) and the US National Institutes of Health (NIH). He is currently Chief Investigator for the United Kingdom Transcatheter Aortic Valve Implantation (UK TAVI) Trial, which is funded by the NIHR Health Technology Assessment Programme.
