World-first trial finds statins safely cut heart attack and stroke risk in healthy over-70s

Statins are already commonly prescribed to people under the age of 75 who meet certain risk criteria, such as having diabetes and high cholesterol, to prevent a major heart event such as a heart attack, stroke, or the need for heart surgery.

The new trial set out to test whether the same protection applies to otherwise healthy people over 70, a group that has received limited attention in cardiovascular prevention research. The results, reported by Guardian medical editor Melissa Davey, found the medication reduced the risk of heart attack or stroke in this older population, while the rate of serious side effects remained low.

The findings raise the prospect that preventative statin treatment could be extended to healthy older adults, although full study details — including the number of participants and the size of the risk reduction — have not been disclosed in reporting on the trial.

Why This Matters

The trial provides the first clinical evidence that healthy people over 70 can benefit from cholesterol-lowering treatment, potentially widening the group offered preventive care.
It addresses a common medical uncertainty: whether the benefits of statins for older adults without existing risk factors outweigh the risk of side effects.
If reflected in updated guidelines, the results could change routine prescribing decisions as populations age.

Background

Statins are among the most widely prescribed medicines in the world, used to lower cholesterol and reduce the risk of cardiovascular disease. Clinical guidance has traditionally focused preventive use on patients under 75 who have risk factors such as diabetes or high cholesterol. Whether otherwise healthy older adults should take statins has long been debated, in part because this age group has been underrepresented in large clinical trials. The Australian-led trial was designed to produce evidence specific to that group.

Key Perspectives

Researchers: They describe the trial as a world first, providing evidence that statins safely reduce heart attack and stroke risk in healthy over-70s. Clinicians: The low rate of serious side effects could reassure doctors who have been cautious about prescribing statins to older patients without established risk factors. Many will want to weigh the findings against each patient's broader health profile. Skeptics: Without full study figures — including participant numbers and the absolute reduction in risk — some may question how large the benefit is in real-world terms, and whether routine prescribing in this age group is justified.
