WASHINGTON: A new study has revealed that 21.5 million additional adults in the United States may now qualify for statin therapy under the new cholesterol guidelines released in 2026, potentially expanding treatment to more than half of U.S. adults between the ages of 30 and 79.
The study, published on July 20 in the prestigious medical journal JAMA (Journal of the American Medical Association), evaluated how the 2026 blood cholesterol guidelines issued by the American Heart Association (AHA), the American College of Cardiology (ACC), and nine partnering medical societies compare with the previous 2018 cholesterol guidelines.
Researchers found that the updated recommendations could increase the number of Americans eligible for statins—medications used to lower cholesterol—from previous estimates to approximately 87.5 million adults, representing more than 50% of the U.S. population aged 30 to 79.
Why the New Cholesterol Guidelines Matter
The updated cholesterol guidelines place greater emphasis on preventing heart disease before it develops, encouraging healthcare providers to identify individuals who may benefit from earlier treatment based on their overall cardiovascular risk.
Statins help lower low-density lipoprotein (LDL) cholesterol, commonly known as “bad cholesterol,” reducing the risk of heart attacks, strokes, and other cardiovascular diseases.
Researchers say the revised recommendations reflect the latest scientific evidence showing that earlier intervention can significantly improve long-term heart health.
Eligibility Does Not Mean Medication Is Automatic
Although the new cholesterol guidelines expand the number of people who may qualify for statin therapy, experts stress that eligibility does not automatically mean a person should begin taking medication.
Instead, healthcare providers are encouraged to evaluate each patient’s individual risk factors before recommending treatment.
These factors include:
- Current cholesterol levels
- Blood pressure
- Age and overall health
- Diabetes status
- Smoking history
- Family history of cardiovascular disease
- Lifestyle and dietary habits
Medical professionals say treatment decisions should always involve shared discussions between patients and their healthcare providers.
Expert Explains the Findings
To help explain the study, CNN interviewed Dr. Leana Wen, an emergency physician and clinical associate professor at George Washington University.
Dr. Wen said the revised cholesterol guidelines are designed to identify more people who could benefit from preventive treatment before experiencing a serious cardiovascular event.
She emphasized that medications should complement—not replace—healthy lifestyle choices.
Heart Disease Remains America’s Leading Killer
According to health experts, heart disease continues to be the leading cause of death in the United States, making cholesterol management a key public health priority.
The expanded eligibility under the new cholesterol guidelines could help millions of Americans reduce their long-term risk of:
- Heart attack
- Stroke
- Coronary artery disease
- Other cardiovascular complications
Experts continue to recommend maintaining a heart-healthy lifestyle, including:
- Eating a balanced diet rich in fruits, vegetables, and whole grains.
- Exercising regularly.
- Maintaining a healthy weight.
- Avoiding smoking.
- Managing blood pressure and diabetes.
- Receiving regular cholesterol screenings.
What Patients Should Do
Health experts advise individuals not to start statin medications on their own simply because they qualify under the new guidelines.
Instead, patients should consult their healthcare providers to discuss:
- Their 10-year cardiovascular risk.
- Current cholesterol test results.
- Possible benefits and risks of statin therapy.
- Whether lifestyle changes alone may be sufficient.
- The most appropriate personalized treatment plan.
The study concludes that the new cholesterol guidelines have the potential to improve preventive heart care for millions of Americans by identifying more adults at risk of cardiovascular disease before life-threatening complications occur.
