Published in the New England Journal of Medicine and presented at the European Society of Cardiology Congress in Germany, the decade-long trial found that the treatment carries a low risk of serious side effects while filling a critical historical gap in preventive cardiology for older adults.
STAREE Trial Results on Statin Use Over 70
The Statins in Reducing Events in the Elderly (STAREE) trial analyzed cardiovascular outcomes for nearly 10,000 participants over the age of 70 who were assigned either a daily statin or a placebo.
Participants in the trial lived independently and had no prior history of heart attacks, strokes, or heart surgery. Adjunct Professor Mark Nelson, a co-author of the study from the Monash University school of public health and preventive medicine, noted that older populations were largely excluded from early statin research because public health efforts 40 years ago focused primarily on preventing premature deaths in middle-aged smokers.
According to the research, individuals aged over 70 experienced a 30% reduction in their risk of encountering a first major cardiovascular event when taking the medication.
In practical terms, according to the research data, one major cardiac event—such as a heart attack, stroke, or heart surgery—can be prevented for every 37 older adults treated with daily statins over a period of almost six years.
Comparing Statin Guidelines Across Age Groups
Statins are already widely prescribed to individuals under 75 who meet specific risk criteria, such as managing diabetes and high cholesterol, as well as to patients of any age who have already experienced a major cardiac event. However, medical guidelines for otherwise healthy adults over 70 have remained less definitive.
Professor Derek Chew, chief scientific and medical officer at the National Heart Foundation of Australia, stated that older individuals face elevated risks of heart attacks and strokes primarily due to increasing age. Although people commonly believe heart attacks typically result in immediate fatality, Chew pointed out that the majority of patients pull through and frequently develop chronic conditions like heart failure. Preventive therapies such as statins aim to keep older adults out of hospitals and living independently.
Pro Tip: Researchers advise older patients to have a direct conversation with their GP during their next appointment to review their five-year cardiovascular risk and discuss whether starting statin therapy is appropriate for their individual health plan.
Addressing Side Effect Concerns and Treatment Adherence
The trial also evaluated common safety concerns associated with long-term statin use. Professor Tom Marwick, a cardiologist at the Royal Hobart Hospital, stated that previous misinformation regarding statins and an increased risk of dementia had made some older patients reluctant to take the drugs. The Monash study found no statistically significant difference in dementia rates between participants who received a statin and those who received a placebo.
Despite the positive cardiovascular findings, the trial highlighted challenges regarding patient persistence. Marwick noted that more than 15% of patients in the trial discontinued their medication. Furthermore, the study found that disability-free survival rates remained identical between participants taking the statin and those taking the placebo, meaning the medication reduced cardiovascular events without extending overall life or disability-free longevity.
Lead researcher Adjunct Professor Sophia Zoungas stated that the research team hopes to see updated treatment guidelines from organizations like the National Heart Foundation of Australia within the next six months to help clinicians apply these findings in everyday practice.
Did You Know? Statins block the production of cholesterol in the liver, which lowers the amount circulating in the blood and can help reduce and reverse cholesterol deposits in human arteries.
Frequently Asked Questions
Do statins increase the risk of dementia in older adults?
According to the STAREE trial published in the New England Journal of Medicine, researchers found no statistically significant difference in dementia rates between study participants who received a daily statin and those who received a placebo.
Who should consider taking statins based on the new trial?
Researchers suggest that otherwise healthy adults over the age of 70 who live independently should discuss their five-year cardiovascular risk with a general practitioner to determine if daily statin therapy is appropriate.
What is the primary benefit of taking statins after age 70?
The decade-long study demonstrated a 30% reduction in the risk of a first major cardiovascular event, such as a heart attack, stroke, or required heart surgery, for healthy adults aged 70 and over.
Will taking statins extend overall life expectancy?
While the trial successfully demonstrated a reduction in major heart events, researchers observed that disability-free survival rates were the same for participants taking statins compared to those taking a placebo.
