Doctors should begin treating high cholesterol earlier and more aggressively than in the past, according to a new medical perspective written by researchers from Weill Cornell Medicine, NewYork-Presbyterian, and Yale School of Medicine.
The experts say updated cholesterol guidelines released in 2026 by the American College of Cardiology and the American Heart Association focus strongly on prevention and early action before serious heart problems develop.
The perspective was published in the Journal of the American College of Cardiology and highlights the important role primary care doctors may play in preventing heart disease.
Heart disease remains the leading cause of death in the United States and is also one of the biggest health problems worldwide. High cholesterol is one of the major contributors to heart attacks and strokes because excess cholesterol can slowly build up inside blood vessels over many years.
This buildup forms plaque, which narrows and hardens arteries. Over time, plaque can reduce blood flow or suddenly break open, causing dangerous blood clots that may lead to heart attacks or strokes.
For decades, doctors often focused mainly on short-term risk when deciding whether to prescribe cholesterol-lowering medications. Many treatment decisions were based on whether someone was likely to experience a heart attack or stroke within the next 10 years.
However, researchers now believe this approach may miss many younger adults who already have hidden risk factors and may slowly accumulate damage long before symptoms appear.
The updated guidelines encourage doctors to focus more on lifetime cardiovascular risk rather than only short-term risk.
Dr. Madeline R. Sterling, an associate professor of medicine at Weill Cornell Medicine and lead author of the perspective, explained that primary care doctors are in a unique position to help prevent cardiovascular disease because they build long-term relationships with patients over many years.
She said primary care clinicians can encourage healthy lifestyle habits such as exercise, healthy eating, better sleep, and smoking cessation while also identifying hidden cardiovascular risks earlier.
The new guidelines encourage doctors to look beyond traditional cholesterol tests alone. Researchers now recommend additional tools that may help detect heart disease risk much earlier.
One of these tools measures lipoprotein(a), also known as Lp(a). This is a genetically inherited cholesterol-related particle that has been linked to increased heart disease risk. Many people may carry high Lp(a) levels without realizing it because standard cholesterol tests do not always measure it.
Another recommended tool is the coronary artery calcium scan, often called a CAC scan. This scan uses imaging technology to detect calcium buildup inside the heart’s arteries. Calcium buildup is a sign that plaque may already be developing, even before symptoms occur.
The guidelines suggest that identifying these hidden risks earlier could help doctors start preventive treatment sooner, including statin medications and lifestyle changes.
Statins are among the most commonly prescribed cholesterol-lowering drugs in the world. They help reduce levels of LDL cholesterol, often called “bad cholesterol,” which contributes to plaque formation in arteries. Research has shown that statins can significantly lower the risk of heart attacks and strokes in many people.
The updated recommendations emphasize that cholesterol damage builds slowly over a lifetime. Even moderately elevated cholesterol levels in younger adults may become dangerous after many years if not controlled.
The researchers believe earlier intervention may help prevent future cardiovascular disease before irreversible damage develops.
However, the authors also acknowledge that putting these recommendations into practice may not be easy.
Primary care doctors often have limited time during appointments and must manage many medical issues at once. Explaining long-term cardiovascular risk, discussing advanced cholesterol tests, and reviewing preventive medications may require lengthy conversations over multiple visits.
Dr. Erica S. Spatz from Yale School of Medicine, who co-authored the perspective, noted that collaboration between primary care doctors, cardiologists, pharmacists, nurses, and other specialists will likely become increasingly important.
The guidelines promote team-based care to help patients better manage cholesterol and reach treatment goals.
The researchers also warned that advanced testing and newer cholesterol medications may not be equally available to everyone. Some tests and treatments may not be covered by insurance or easily accessible in lower-income communities. This raises concerns that healthcare inequalities could worsen if access is limited.
To address these challenges, the authors say healthcare systems may need better insurance coverage, improved patient education, stronger electronic health record systems, and closer cooperation between healthcare professionals.
The perspective also highlights a broader shift happening in modern medicine. Increasingly, doctors are moving toward prevention rather than waiting until serious disease develops.
Scientists now understand that many chronic diseases, including heart disease, often begin silently decades before symptoms appear. Early detection and prevention may help people stay healthier longer and reduce long-term healthcare costs.
