Ask for a referral to a cardiologist. Then request a scan of plaque build up in your arteries etc. I understand the results of this scan can determine if you need to be on statins .

Hmmmm, I'm not sure that would tell you whether you need to be on statins from the perspective of the NHS/medical personnel. It would tell you what state your arteries are in now (great) but they seem to dish out statins mainly on the basis that you MAY get issues in 10 years time! You can't win when you have these conversations with them,'Ateries blocked?, statins', 'Arteries clear?, statins, because they might become blocked'. Al you can do is plenty of research and decide for yourself.
