If you actually believe the Lipid hypothesis of Coronary Heart Disease, then if you are also under 60 and male there may be enough evidence that Statins can reduce the risk of a (probably non-fatal) heart attack. However even though non of the actual figures for all these Statin trials by Big Pharma have ever been released - just the portions of their own analysis which they want released, that alone shows A). Statins for women over 60 actually shortens their lives. B) even in men, the all-cause mortality is lower in those with Higher LDL i.e there is doubt that statins do any good.
In a talk 2yrs ago to the Public Health Collaboration Conference, Dr Malcom Kendrick presented a list of many more significant potential causes of Heart Disease than LDL which included Lead, Smoking, Air Pollution the drug AVASTIN , he also showed a list of more significant things associated with a drop in Heart Disease which included VIAGRA (50 times more significant), Exercise, Vitamin C, Vitamin D, Sunshine, and ASPIRIN.

Here is a link to Dr Aseem Malhotra (Cardiologist) talking about the lack of independent evidence:
Edited to say that although upon TD diagnosis, I persuaded my GP to reduce my Statin dose, I am still taking a lower dose of Atorvastatin (Lipitor).
