Paradox or inappropriate use of statins?

"This survey investigates the use of statins in individuals older than 79 years by vascular disease.

There is little randomized evidence to guide the use of statins (HMG-CoA reductase inhibitors) in very elderly individuals (>79 years).1,2 Despite this, the very elderly have the highest rate of statin use in the United States.3 Given that few studies have investigated the use of statins among this population in a longitudinal manner by vascular disease, we set out to do so."
