I have a simple rule: if a patient is over 90, they do not get any new medications, and I will require specific proof to keep them on current meds. Anyone that would Rx any new drug to someone that was alive for World War I should lose their license.
As for statins, I have not seen specific proof that they are ever helpful for actual life expectancy....my analogy to patients is that taking a statin to lower an LDL number is like taping the wings back onto a 747 airliner to convince people to buy a ticket to get on it....sure, you made it LOOK like you did something, but the damn thing still ain't flying. It is taking a pretty pocketknife to a problem (metabolic syndrome, or NOTHING BUT GENES in many other cases) that requires a machete.
Cholesterol high + metabolic syndrome markers => drugs of any kind will do nothing to prolong life. Only effective treatment is overhaul of all of the patient's diet regimen. Everything else is wishful thinking.
Cholesterol high + NO markers, hereditary or diet justifying => Relax. Do nothing. Pass the bacon.
Not rocket surgery folks
