Management of Left Main Stem coronary disease

10 December, 2019

The left main stem is the artery supplying blood to the left ventricle, the main pumping chamber of the heart.  Any disease involving this vessel can jeopardise the function of the heart and the patients life.  Until recently, in most cases, narrowing to the left main stem was managed by coronary artery bypass grafting (CABG).  Newer guidelines have recommended that stents or percutaneous intervention (PCI) could offer equivalent results.  Much of the evidence from this has been base on a single study called EXCEL.


The results of this study have been questioned by a recent Newsnight investigation.  Essentially, not all the data has been made available, as was promised, and it is possible that there were more heart attacks in the patients treated with PCI.  This has led leaders in the field to ignore the guidelines until this can be investigated further.

The Rise of Smartphones and Wearables in the Detection of Atrial Fibrillation

1 April, 2019

Atrial fibrillation is the most common arrhythmia and increases with age.  Those with atrial fibrillation (AF) have a three to five fold increase in risk of stroke and are more likely to die or suffer disability if they do have a stroke.  AF is traditionally diagnosed with an ECG but there is growing evidence for implantable monitors, patch monitors, smartphones and now, smart watches.

The results of the Apple heart study were announced recently at the European Heart Rhythm meeting in Lisbon.  The study included more than 400,000 people, yet only 6% were over the age of 65.  The detection rate was 0.2%.  More research in the area is required, especially in an older population but this is a promising first step and now means accurate AF detection can be initiated by patients without expensive medical equipment.

Dr Roger Beadle​ - Warwick Cardiologist

Welcome to my website.  I am a Consultant Cardiologist with experience in all aspects of cardiology.  I have been a consultant since April 2014 having completed 10 years of specialist training in the West Midlands and was proudly appointed to South Warwickshire NHS Foundation Trust in 2015.

Background and Experience

I graduated from the University of Queensland, Australia in 1998 and undertook two years of work for Queensland Health in both large teaching hospitals and rural environments.  I moved to the UK in 2000 against the prevailing tide of emigrating doctors to gain experience in the NHS, and never looked back.  I completed my junior doctor training in Bath and was awarded my MRCP by the Royal College of Physicians, London.  I then worked briefly in the Oxford Deanery before starting specialist training in the West Midlands where I worked in all of the major cardiology units gaining broad experience.  I sub-specialised in Heart Failure and Cardiac Devices (pacemakers and defibrillators) having been trained by international experts in the field.


As part of my training I undertook a period of research looking into a novel treatment for heart failure.  This research was sponsored by the British Heart Foundation and led to the award of a PhD in 2013 by the University of Aberdeen.  A list of my publications can be found by clicking here.
