If you’re like most people, you probably think discussions about heart health or medications to lower LDL “bad” cholesterol don’t need to happen until you’re middle-aged or older.
Here’s what to know about this changing perspective on heart disease risk and what it means at every age.
1. Cardiologists Are Rethinking Who Can Most Benefit From Statins
The new guidelines reflect a broader shift toward thinking about lifetime heart disease risk, not just what might happen over the course of, say, 10 years. The goal is not to start everyone on a statin or other cholesterol-lowering drug as soon as possible, but rather to identify who could benefit from earlier intervention.
“The higher your risk, the stronger the recommendations are for treatment,” says Pamela Morris, MD, a cardiologist and professor at the Medical University of South Carolina in Charleston, and vice chair of the writing committee for the 2026 guidelines.
Even in younger adults, that balance can favor treatment, Dr. Morris says.
“At age 30, someone at borderline risk may already be more likely to benefit from a statin than be harmed — and that benefit becomes clearer at higher risk levels,” she says.
Risk can be classified as low, borderline, intermediate, high, or very high, based on factors including current cholesterol levels, diabetes, smoking, weight, and family history.
The updated guidelines set the following LDL cholesterol level targets:
- Below 100 mg/dL for people at borderline or intermediate risk
- Below 70 mg/dL for those at high risk
- Below 55 mg/dL for people at very high risk
Research continues to show that lowering LDL to even very low levels remains safe and continues to reduce risk, says Eric J. Brandt, MD, director of preventive cardiology at the University of Michigan Health Frankel Cardiovascular Center in Ann Arbor. “People were still getting heart disease at the previous LDL thresholds,” he says.
The previous recommendations, published in 2018, focused on percentage-based LDL reductions. While some doctors had already been recommending levels below 100 or 70 mg/dL for intermediate and high risk, respectively, the new recommendation to get LDL down to 55 mg/dL for people at very high risk is new and more aggressive.
2. Heart Disease Risk Often Starts Earlier Than People Think
The new guidelines are based on a growing body of research showing that cardiovascular disease develops gradually — often long before symptoms appear.
“We know that cholesterol starts building up in the arteries many years, if not decades, before someone’s first heart attack, often even before age 30,” says Ann Marie Navar, MD, PhD, a cardiologist at UT Southwestern Medical School in Dallas and a member of the guideline writing committee.
“We are also seeing concerning trends in risk factors, including obesity and diabetes, in younger adults,” says Harlan Krumholz, MD, a cardiologist and professor at Yale School of Medicine in New Haven, Connecticut. “More people are developing cardiovascular disease earlier in life, hence the focus on risk reduction in younger populations,” he says.
Dr. Brandt agrees. “Unfortunately, we’ve started to lose ground in heart disease prevention.”
In a recent analysis of nearly one million hospitalizations, deaths after a first heart attack increased among adults aged 18 to 54 between 2011 and 2022, with women more likely than men to die.
3. If You’re at Higher Risk, Starting Earlier May Offer More Protection
For people at higher risk, the benefit of treatment isn’t just about lowering cholesterol in the moment — it’s about keeping levels low over the long-term.
“The goal is to reduce cumulative exposure to high LDL over decades with medications known to reduce risk,” says Dr. Krumholz.
“Statins are also among the most well-studied medications in cardiovascular care, with decades of data supporting their safety and effectiveness,” says Krumholz. While studies haven’t followed patients for 40 or 50 years, existing evidence suggests the benefits outweigh the potential negatives for people at higher risk of heart disease, he adds.
4. Prevention Starts Earlier Than You Might Expect — Even in Childhood
The shift toward earlier treatment doesn’t stop with younger adults.
The guidelines recommend cholesterol screening beginning in early adulthood and even earlier in children — including routine testing between ages 9 and 11, or at younger ages for those with a strong family history.
That’s because early exposure to high cholesterol is linked to the development of artery plaque years before symptoms appear.
Identifying risk early, especially because of inherited conditions like familial hypercholesterolemia — a condition that causes extremely high LDL cholesterol and premature heart disease — can help patients start treatment earlier and hopefully experience better long-term health.
5. If Followed, the New Guidelines Will Save Lives
Experts say the potential impact of the guidelines change is significant, if the recommendations are widely adopted.
“If everyone at risk lowered their LDL cholesterol to guideline-recommended levels, we would prevent not only heart attacks and strokes, but also save lives,” says Dr. Navar.
Part of the issue is how soon and how consistently the guidelines are applied and whether people can access and stay on treatment. There’s evidence that it takes more than a decade for doctors and patients to accept and implement new guidelines — and the country as a whole is still doing very poorly in implementing the previous cholesterol guidelines from 2018, says Morris.
That’s why it’s “super important” for people to know about these new recommendations, to hopefully prevent more illness and deaths caused by heart disease, she says.
How to Talk with Your Doctor About the New Recommendations
“The guidelines emphasize shared decision-making,” says Morris.
Ideally, you and your doctor or other care provider can discuss evidence and your individual risk, preferences, and goals — so you can make the best decision for you, she says.
And if you’re reluctant to start treatment because you’ve seen social media posts emphasizing the dangers of statins, discuss your concerns with your provider, says Morris. “Online sources aren’t the most accurate place to get your information about the benefits or side effects of potential treatments,” she says.
