In contrast to NICE’s 2006 recommendations,2 which focused on identifying the 45% patients at the greatest risk of stroke and offering them anticoagulation, doctors should now try to identify the 6-10% of patients at the lowest risk of stroke and offer anticoagulation to the rest, Campbell Cowan, chairman of the guideline development group, told a press conference in London on 17 June.
The new guideline recommended that doctors use a new tool—the CHA2DS2-VASc—to assess the risk of stroke in people with atrial fibrillation to help distinguish between those with a low risk who do not need anticoagulation and those with a higher risk who do. Around 200 000 patients with atrial fibrillation are currently prescribed aspirin for stroke prevention, but Cowan said that …
