Consultant Cardiologist & Professor of Cardiovascular Medicine, Director – Haemostasis Thrombosis & Vascular Biology Unit, Cardiovascular and Respiratory Sciences
Professor Gregory YH Lip has had a major interest into the epidemiology of atrial fibrillation (AF), the commonest cardiac rhythm disorder, as well as the pathophysiology of thromboembolism in this arrhythmia. Furthermore, he has been researching stroke and bleeding risk factors, and improvements in clinical risk stratification. The CHA2DS2-VASc and HAS-BLED scores for assessing stroke and bleeding risk respectively were first proposed and independently validated following his research and are now incorporated into major international management guidelines, including those from Europe, USA and the National Institute for Health and Care Excellence (NICE). In January 2014, Professor Lip was ranked by Expertscape as the world's leading expert in the understanding and treatment of AF.
