Statins After 70: Continue or Stop?
Statins are widely prescribed to lower cholesterol and prevent heart attacks and strokes. However, for adults over 70 who have never experienced a cardiovascular event, the long-term benefits of statins have been debated. A major study presented at the American Heart Association's Scientific Sessions 2026 offers new evidence on this clinical dilemma.
How Was the Study Conducted?
The study enrolled nearly 1,900 adults aged 70 and older who were taking statins for primary prevention, with an average age of 77. Every participant had at least two chronic conditions, such as a history of cancer or lung disease. Participants were divided into two groups: one stopped statins, and the other continued treatment. Researchers tracked health outcomes for about two years, with follow-up extending up to four years, recording heart attacks, strokes, deaths, quality of life, muscle pain, falls, and muscle wasting.
Short-Term Results: Reassuring News
After approximately two years, there was no statistically significant increase in heart attacks, strokes, or deaths among those who stopped statins compared with those who continued. Stopping treatment also did not produce measurable improvements in quality of life, muscle discomfort, falls, or muscle wasting. However, data indicated approximately one additional cardiovascular event for every 40 people who discontinued statins—a small but noteworthy difference.
Longer Follow-Up: A Risk Signal Emerges
Over up to four years, 12.7% of participants who stopped statins experienced a heart attack, stroke, or death, compared with 9.2% of those who continued. Study author Dr. Rita F. Redberg, professor of cardiology at the University of California, San Francisco School of Medicine, noted that this longer-term risk difference is a new finding not seen in earlier studies, possibly because this trial included more participants and tracked them longer.
Expert Advice: Individualized Decisions Are Key
"This small, increased risk of cardiovascular events means that one cannot make a general recommendation about stopping statins in this patient population," Dr. Redberg said. "There should be shared decision-making between the patient and the healthcare professional. In general, however, discontinuation is safe for most people in this age group without a previous CVD event."
Study Limitations and Caveats
- The study was conducted across 24 medical centers in Switzerland, France, and the Netherlands; generalizability to other populations requires further validation.
- About 14% of participants switched treatment groups during the study, but additional statistical analyses showed results remained unchanged.
- All participants had at least two chronic conditions, representing a less healthy population than all adults over 70.
Practical Advice for Older Patients
If you or a family member are taking statins for primary prevention, do not stop without consulting a doctor. Discuss personal cardiovascular risk, comorbidities, and quality of life to develop an individualized plan. Regular monitoring of cholesterol and cardiovascular indicators supports informed decision-making.
