Prof. Gregory Y. H. Lip
This Meet the Expert session was chaired by G.Y.H. Lip (Birmingham, GB) and L. Friberg (Stockholm, SE), accompanied by expert panellists, Dr F Marin (Spain), Dr L H Rasmussen (Denmark) and Dr A Bollmann (Germany). Dr Marin presented a case of the 74 year old man with peripheral artery disease - how to assess risks of stroke, bleeding and falls. This led to lively discussion on the importance of the CHA2DS2-VASc score over CHADS2, as well as the independent additive effect of peripheral artery disease to the predictive value of the CHADS2 score . Bleeding risk is assessed by the HAS-BLED score, and has been well-validated in recent studies, even being superior to other scores (including the ATRIA score) [2,3,4]. Dr Bollmann discussed a case of the young female patient undergoing AF ablation - should we anticoagulate? Recent studies have shown that female patients overall have an increased risk of stroke in AF, but there is an age effect [5,6]. If a female patient fulfils the criteria of ‘age <65 and lone AF’ their risk of stroke is so low, that antithrombotic therapy is not recommended. The recent joint guidelines following ablation therapy were discussed . Prof Lip closed the session with a presentation on ‘What do the Guidelines say?’ with particular reference to the new 2012 focused update guidelines on AF management , published and presented at this meeting. The important point in this guideline is the practice shift towards identification of ‘truly low risk’ patients with AF who do not need any antithrombotic therapy, whilst those with one or more stroke risk factors can be offered effective stroke prevention, which is oral anticoagulation therapy whether with well controlled warfarin (INR 2-3) or one of the novel anticoagulant drugs.
