If you’re like most people, you probably think that discussions about heart health and drugs to lower LDL “bad” cholesterol aren’t necessary until middle age or older.
Here’s what you need to know about this changing view of heart disease risk and what it means at each age.
1. Cardiologists are rethinking who can benefit most from statins
The new guidelines reflect a broader shift in thinking about heart disease risk over a lifetime, rather than just what might happen over, say, 10 years. The goal is not to start everyone on statins or other cholesterol-lowering drugs as soon as possible, but to identify who would benefit from earlier intervention.
“The higher the risk, the stronger the recommendation for treatment,” says Dr. Pamela Morris, a cardiologist and professor at the Medical University of South Carolina in Charleston and vice chair of the 2026 guidelines committee.
Even in young adults, Dr. Morris says, that balance can favor treatment.
“At age 30, people at borderline risk may already be more likely to benefit than harm from statins, and the benefits become more apparent at higher risk levels,” she says.
Risk can be categorized as low, borderline, intermediate, high, or very high based on factors such as current cholesterol levels, diabetes, smoking, weight, and family history.
The updated guidelines set the following LDL cholesterol level goals:
- Less than 100 mg/dL for people at borderline or moderate risk
- High-risk individuals are less than 70 mg/dL
- Less than 55 mg/dL for people at very high risk
Eric J. Brandt, MD, director of preventive cardiology at the Frankel Heart and Vascular Center at Michigan Health University in Ann Arbor, says research continues to show that lowering LDL to very low levels is safe and continues to reduce risk. “Even at previous LDL thresholds, people still had heart disease,” he says.
Previous recommendations issued in 2018 focused on percentage-based LDL reduction. Although some doctors were already recommending levels below 100 mg/dL or 70 mg/dL for intermediate and high risk, respectively, the new recommendation to lower LDL to 55 mg/dL for very high-risk people is new and more aggressive.
2. Heart disease risk often starts earlier than people think.
The new guidelines build on a growing body of research showing that cardiovascular disease develops gradually, often long before symptoms appear.
“We know that cholesterol begins to build up in the arteries years, if not decades, before the first heart attack, often even before the age of 30,” says Anne-Marie Navar, M.D., a cardiologist at the University of Texas Southwestern Medical School in Dallas and a member of the guideline-writing committee.
“We’re also seeing worrying trends in risk factors such as obesity and diabetes among younger people,” says Harlan Krumholtz, M.D., a cardiologist and professor of medicine at Yale University in New Haven, Connecticut. “With more people developing cardiovascular disease earlier in life, there is a focus on risk reduction in younger generations,” he says.
Dr. Brandt agrees. “Unfortunately, we are starting to lose ground in heart disease prevention.”
A recent analysis of nearly 1 million hospitalized patients found that first-time heart attack deaths increased among adults aged 18 to 54 from 2011 to 2022, with women more likely to die than men.
3. If your risk is high, starting earlier may provide more protection
For people at high risk, the benefit of treatment is not only to lower cholesterol now, but also to keep cholesterol levels low over the long term.
“The goal is to reduce decades of cumulative exposure to high LDL using drugs that are known to reduce risk,” Dr. Krumholz says.
“Statins are also among the most well-studied drugs in cardiovascular treatment, with decades of data supporting their safety and efficacy,” Krumholz says. Although the study did not follow patients for 40 or 50 years, existing evidence suggests the benefits outweigh any potential downsides for people at high risk for heart disease, he added.
4. Prevention starts earlier than expected – even in early childhood.
The transition to early treatment is not limited to young adults.
Guidelines recommend starting cholesterol screening in early adulthood and even earlier in childhood. This includes regular testing between ages 9 and 11, or even at a younger age if there is a strong family history.
That’s because early exposure to high cholesterol is associated with the development of arterial plaque years before symptoms appear.
In particular, early identification of risks from genetic conditions, such as familial hypercholesterolemia (a disease that causes extremely high LDL cholesterol and premature heart disease), can help patients start treatment sooner and lead to improved long-term health outcomes.
5. If followed, the new guidelines will save lives.
Experts say the potential impact of the guideline changes is significant if the recommendations are widely adopted.
“If everyone at risk lowered their LDL cholesterol to guideline-recommended levels, we would not only prevent heart attacks and strokes, but also save lives,” Dr. Navarre says.
Part of the question is how quickly and how consistently the guidelines are applied, and whether people can stay on treatment. There is evidence that it takes doctors and patients more than a decade to accept and implement new guidelines, but nationally the implementation of the previous cholesterol guidelines from 2018 remains very poor, Morris said.
That’s why it’s “so important” that people know about these new recommendations to prevent further illness and death from heart disease, she says.
How to talk to your doctor about new recommendations
“The guidelines emphasize shared decision-making,” Morris said.
Ideally, she says, you and your doctor or other health care provider will discuss the evidence and your personal risks, preferences, and goals so you can make the best decision for you.
Also, if you’re hesitant to start treatment because you’ve seen social media posts highlighting the risks of statins, discuss your concerns with your doctor, Morris says. “Online sources are not the most accurate place to get information about the benefits and side effects of potential treatments,” she says.
