Statins Cut Heart Attack Risk 30% in Over-70s, Australian Trial Shows

A landmark clinical trial led by Monash University researchers found that statins reduce the risk of heart attacks and strokes by 30% in healthy people aged 70 and over. The study of nearly 10,000 participants, published in the New England Journal of Medicine on August 29, shows the cholesterol-lowering drug carries a low risk of serious side effects in this age group. Until now, doctors lacked clear evidence on whether to prescribe statins as a preventive measure to healthy older Australians.

What the STAREE trial discovered

The double-blind study, called STAREE, tracked participants aged 70 and over who had no history of heart disease, diabetes, or dementia. Half received a daily statin (atorvastatin), half a placebo. Over six years, statins reduced major cardiovascular events by 30% compared to placebo. Treating 37 older people with daily statins for nearly six years could prevent one serious event such as a heart attack, stroke, or need for heart surgery.

Why this matters for Australian doctors and patients

Between 2.2 million and 2.6 million Australians already take statins daily. Current guidelines recommend them for people aged 45 to 79 assessed as high risk, and for anyone with established heart disease. The new evidence fills a gap: doctors previously had no robust data on prescribing statins to healthy people over 75. An estimated 21,000 older Australians suffer major cardiovascular events each year. Dr Mark Nelson, co-author and GP at Monash University, said the findings would change how doctors manage heart attack and stroke risk in older people.

Dementia fears dispelled, but some limits remain

The trial found no statistically significant difference in dementia incidence between the statin and placebo groups, countering a persistent false claim. However, disability-free survival was the same in both groups despite fewer cardiovascular events. More than 15% of participants stopped taking their prescribed drugs. Cardiologist James Chong at Westmead Hospital noted participants were almost exclusively white with an average age of 75, so additional confirmation is needed for other population groups.

What happens next

The findings may be used to inform updated treatment guidelines for cardiovascular risk management in older people. Researchers advised older people to discuss with their doctor whether taking statins is appropriate for them. The trial results were presented at the European Society of Cardiology Congress in Munich on August 29.

Final Thoughts

The STAREE trial provides the first robust evidence that statins safely reduce heart attack and stroke risk in healthy older Australians. Millions may soon be candidates for preventive statin therapy. Older Australians should discuss with their doctor whether statins suit their individual circumstances.
