Updated 2026 U. S.
blood cholesterol guidelines now recommend statin therapy for an estimated 87.5 million adults, nearly 57% of Americans aged 30 to 79 without established cardiovascular disease.

The new framework, published July 20 in JAMA, was developed by the American Heart Association, the American College of Cardiology, and nine partnering societies.
It expands the target age range from 40–75 to 30–79, lowers risk thresholds, and incorporates 30-year risk projections to identify early cardiovascular risks.
Analysis led by Dr. Timothy Anderson of the University of Pittsburgh found that 21.5 million adults are newly eligible under the updated guidance.
This newly eligible group is generally younger and has a lower average 10-year risk of 3.1%, compared to 6.1% under older standards.
Shift Toward Long-Term Risk Assessment
“The shift to a longer view of cardiovascular disease risk is a sea change for doctors in counseling patients,” said Dr. Anderson.
Previously, people in their 30s and 40s with high cholesterol were often advised to focus on diet and exercise rather than medication, unless they had heart disease or high-risk conditions like diabetes.
The updated framework integrates the PREVENT equations, which recalibrate risk assessments and reclassify over one in five adults.
Research led by Allison Peng of Johns Hopkins University found that while risk classifications shift, the total proportion of older adults recommended for therapy remains steady at roughly 49.6%.
Under the new guidelines, 10-year cardiovascular risk is categorized as borderline at 3%, intermediate at 5%, and high at 10%.
