If you are over 74 years old and have not been diagnosed with cardiovascular disease (heart disease, stroke, atherosclerosis), and you are taking a statin (lipitor, crestor, etc) -YOU SHOULD STOP (of course, you should talk to your doctor first).
A large study from the British Medical Journal confirmed what I've thought for a long time - statins DO NOT PROVIDE A BENEFIT in this population (unless you have diabetes). If you have diabetes, there is a benefit with a reduction in cardiovascular events and all case mortality (i.e. dying) until you are 85, then that benefit goes away, too.
Bottom line - Statins continue to come up short as a solution for everyone, despite the push to get nearly everyone on them. Younger people at risk MAY have a reason to take a statin, but that should not be without a full evaluation and a great explanation as to how it will help!
Happy to hear your thoughts!
