I think statins are a very individual choice.
for many late diagnosed the option with change of diet , and possibly some weight loss , combined with results that are marginal , seem to make the decision a bit difficult.
for me -- diagnosed aged 14 in 1972 ( long before cholesterol reducing drugs had been introduced )
the theory was to keep blood pressure and cholesterol controlled ( through diet) to assist in reducing the possibility of long term complications that were known to exist at that time , in terms of heart attacks , strokes , and kidney disease.
perhaps the medical community have not moved with the times ..... but for me still here after 45 years diagnosed and living pretty well -- I am in favour of statins for some ( though maybe not all ))
said my piece ( don't shoot the messenger !!
