I think my OH is probably alive today aged 74 because he started taking statins in his 40s. He has a strong history of cardio vascular disease in his family, his father died aged 48 from a heart attack.
His cholesterol was raised, in particular the LDL (bad cholesterol) so it is probably familial. He does take Co Enzyme Q10 for muscular cramps but his GP was sceptical about this. It has helped, but possibly placebo
.
You really have to weigh up your individual risks after discussing with your GP. Whether you smoke, are diabetic, or have a raised blood pressure, and a raised LDL cholesterol is used to calculate risk.
