Fueling the Debate on Statin Use in Older Adults

The use of statins for primary cardiovascular disease prevention in adults over age 75 is clouded in uncertainty. A recent study in the Journal of the American Geriatrics Society found that statins may significantly lower mortality risk in older adults. That only underscores the need for a large-scale, prospective, randomized clinical trial, researchers say.
