Here is an article that discusses a Cochrane Review on primary prevention with statins. That is people like me. No risk factors. It also discusses the use of the drugs in secondary prevention. Those that at are at higher risk for vascular events - heart attacks and strokes. Make of it what you will. This is the best evidence available from the scientists. If I had high cholesterol - I would alter my diet, exercise, stop smoking and reduce my BP if I had those risk factors - and start statins!
