Why do you take them? Because science shows there is no overall reduction in mortality. But if you want to brag about cholesterol numbers, maybe they are okay.
I'm not a physician.I didn't even stay at a Holiday Inn last night.But I have worked for decades with some of world's finest physicians and surgeons.As a result I'm very strongly inclined to trust this physician's judgment.
I'm also strongly inclined to trust the judgment of senior pilots who fly for major airlines.
Here is some science for you:
(From JAMA Cardiology Jan 2017)
The conclusion: Maximally tolerated doses of high-intensity statins may confer a survival advantage to patients with atherosclerotic cardiovascular disease, including older adults.
Depends if you are talking about primary prevention (people without a history of cardiovascular disease), or secondary prevention (people with established cardiovascular disease). When used for secondary prevention there is definitely data demonstrating reduced mortality. Most of the studies are based not just on mortality, but combined endpoints (e.g. cardiac events, requirement for revascularization, mortality), but there are studies that show a reduction in total mortality while using statins for secondary prevention.
