I had a health scare around 4-5 years ago where they suspected I had angina, it turned out it was inflammation in my chest after a fall several weeks earlier, but whilst in hospital the Cardio Nurse said I should be taking a statin as I'd had type 1 for 30 years and was at a greater risk of CVD (must stress this was before the results of my angio/echogram later in the week).
At the time my TC had gone up to 4.3 where it's usually between 3.5-4.1 but I wasn't too concerned, but when I was discharged I discussed statins with a diabetes consultant who had not seen before, he was of the opinion that all long-term type 1's should take a statin and sent a letter to my gp to prescribe a drug called Simvastatin.
The prescription was sent through the post so I booked in to see my gp and discussed my recent angiogram results and cholesterol history, he disagreed that I should be taking a statin as my hospital results were fine plus I'd never had high cholesterol before, he said as long as I kept to a healthy diet and continued to exercise regularly he was happy for me to continue as I was, we agreed to agree to leave it at that and would review things again in a few years time.
Since then my TC has been below 4 and my lipids are all in range so noting has been mentioned since, hope that helps somewhat
@PseudoBob77 but I must stress that I don't have any issues with taking a statin and if my cholesterol levels were to rise I'd take one to bring them back into line (if dietary measures didn't work), both my mum and a brother took a statin for high cholesterol and both had no side-effects.
