Is Des Spence right about AF? Is AF case finding and anticoagulation bad medicine?

I often read Des Spence's piece in the print journal and last week he wrote about AF. http://www.bmj.com/content/347/bmj.f4910His argument is that AF case finding and anticoagulation is bad medicine. Mine is that in an average patient on a GP list  the stroke risk per year is  is 0 or close to because of the demographics and the way that the statistics of risk play out ( a high risk patient with AF has a stroke risk of about 5% per year). In the same edition there is news piece saying that reconfiguration of stroke care in London has saved lives and money - don't we need a public health perspective on this rather than a primary or secondary care viewpoint?sadian
