in its new guidelines (http://guidance.nice.org.uk/CG/WaveR/123) , NICE have lowered the bar for recommended statin use from people with a 1 in 5 risk of developing a CVD to 1 in 10.
Personally, (and not with my editor hat on) I wonder if such a move is justified. Being doing some research and the NNT appears to be quite, well, a bit rubbish.
(sorry - jargon buster - NNT = Number Needed to Treat = the amount of people you would have to treat before one person gained any benefit; ideally a drug's NNT should be as close to 1 as possible)
One analysis put the NNT for people with no history of heart disease as high as 98 (http://www.thennt.com/nnt/statins-for-heart-disease-prevention-without-prior-heart-disease/) - while the risk of side effects could be as high as 1 in 10
If I was offered statins myself I would probably turn them down and hit the gym instead
