Winner of DTI SMART award 2004
Dr Yuk-ki Wong's undergraduate training was at Manchester University and he graduated with MB ChB in 1990 having gained an intercalated BSc(Hons) in Physiology in 1987. After junior posts in the North West and obtaining his MRCP, he started his cardiology training including research in the Wessex Region during 1993 and was awarded his certificate of completion of specialist training (CSST) in cardiology and general medicine in 2002. He was elected FRCP in 2008.
Since 2003, he has been a Consultant Cardiologist working for the Western Sussex Hospitals NHS Foundation Trust. He is based at St. Richard’s Hospital, Chichester. He is the clinical lead for Heart Failure and is also a General Cardiologist caring for patients with a wide range of conditions including coronary disease, arrhythmias such as atrial fibrillation, valvular heart disease and hypertension. His routine work includes cardiac catheterisation, implantation of permanent pacemakers and both transoesophageal and transthoracic echocardiography. He helped to develop CT coronary angiography at WSHFT. He is also the lead for cardiology research with interests in heart failure, coronary disease, hyperlipidaemia and atrial fibrillation.
Doctor of Medicine Degree (1999)
In the 1990s, there was great excitement because coronary disease was thought to be caused by a bacterium known as Chlamydia pneumoniae which meant it could potentially be eradicated by antibiotics. Under the supervision of Professor Mike Ward at the Department of Molecular Microbiology, Southampton University, Dr Wong worked on projects funded by the British Heart Foundation and Wessex Heartbeat Charity. There was also collaborative work with groups from Oxford, the MRC Environmental Epidemiology Unit and the Biobanque De Picardie. This work resulted in a number of important papers but the results were mixed and it does not look as if Chlamydia is an important cause of coronary disease.
The ALARM study. Predicting when heart attacks will occur
It is often thought that heart attacks occur without warning and unfortunately, death can occur shortly afterwards. Therefore, a tremendous amount of research and re-organisation of services has been carried out in order to treat patients within the first “Golden Hour”.
If patients could be treated in the period before a heart attack, even more lives could be saved. In fact, approximately 50% of patients have unstable angina in the 2 week period leading up to a heart attack with symptoms occurring at lower levels of exertion. Since heart rate is a measure of exertion, then symptoms occurring at low heart rate could be warning for an impending heart attack. Dr Wong was awarded an NIHR grant to test his hypothesis and the results of a clinical trial were promising and published in 2015. Ongoing work involves the development of a reliable, portable heart rate monitor.
Dr Wong is a self taught computer programmer and has developed a number of clinical databases including a Rapid Access Chest Pain Clinic database used in 3 South Coast Hospitals including the Wessex Cardiothoracic Unit at Southampton General Hospital. He also developed Jersey General Hospital's first CCU electronic database. Some of his research pertains to analysis of data from such databases as well as other sources of data including the UK National Census.
Phase III Clinical Trials
Many drugs have been introduced into clinical practice that have improved the lives of patients with cardiac diseases. These drugs were tested in large clinical trials which in total have involved hundreds of thousands of patients and numerous research staff, Principal Investigators and research centres. Dr Wong has been the Principal Investigator for many trials including ILLUMINATE, RIVER, REVEAL, THRIVE, FIDELIO, FIGARO, ODYSSEY, ODYSSEY LONG TERM, CRESCENDO, AVERROES, ARISTOTLE, ATMOSPHERE, CLEAR-HARMONY, COMMANDER, IMPROVE-IT, SIGNIFY, SOLID, STABILITY, EXAMINE, TRANSITION and TRILOGY.
The drugs investigated in these trials include ranolazine, ivabradine, rivaroxaban, ezetimibe, alirocumab, finerenone, anacetrapib, laropiprant, Rimonabant, alogliptin, aliskiren, bempedoic acid, darapladib, torcetrapib and apixaban.
Two new trials that will be commenced in 2018 are IRONMAN which is investigating the role of intravenous iron in heart failure and SELECT which will be investigating the role of semaglutide in reducing cardiovascular risk and weight.
