New Cholesterol Guidelines 2026: What Changed
Medically reviewed by Medical Advisory Board Last reviewed 2026-07-18
How the 2026 ACC/AHA dyslipidemia guideline changed LDL goals, Lp(a) screening, and who needs a statin
The 2026 ACC/AHA dyslipidemia guideline replaced the 2018 cholesterol guideline. It restored numeric LDL-C goals based on risk, added universal once-in-a-lifetime lipoprotein(a) screening, and made weight loss a core recommendation. This is a plain-English guide to what changed and what your cholesterol numbers should be now.
The new cholesterol guidelines for 2026 are the biggest change in cholesterol care in eight years. In March 2026, the American College of Cardiology and American Heart Association released a full rewrite of the 2018 guideline, developed with the National Lipid Association and nine other groups.
The headline change: numeric LDL-C goals are back. The 2018 guideline had moved away from specific targets, and many patients and doctors found that confusing. The 2026 guideline restores clear LDL numbers based on your heart-disease risk.

What Changed From the 2018 Cholesterol Guideline
The 2026 guideline makes three major changes: it restores numeric LDL-C goals, adds universal lipoprotein(a) screening, and makes weight loss a formal recommendation. It also uses a new risk calculator called PREVENT and now covers high triglycerides and Lp(a), not just LDL. Here is how the two versions compare.
| Criteria | 2018 guideline | 2026 guideline |
|---|---|---|
| LDL-C goals | No firm numeric target; "the lower the better" | Numeric goals restored: <100, <70, or <55 by risk |
| Lp(a) screening | Optional, in selected patients | Universal — once in a lifetime for every adult |
| Risk calculator | Pooled Cohort Equations | PREVENT-ASCVD (adds kidney function, statin use) |
| Weight loss | Mentioned | Formal rec: ≥5% loss if overweight with dyslipidemia |
| Scope | Mainly LDL cholesterol | LDL, high triglycerides, and Lp(a) |
What Your LDL Cholesterol Should Be Now
Your LDL-C goal now depends on your heart-disease risk, and the 2026 guideline sets three clear tiers. For most healthy adults, the goal is an LDL under 100 mg/dL. If you have risk factors or a prior heart event, the goal drops to under 70 mg/dL. For very-high-risk people — those with a recent heart attack, stroke, or multiple events — the goal is under 55 mg/dL. These numbers give patients a concrete target to work toward, which the 2018 version lacked. Non-HDL cholesterol goals were also restored alongside LDL.
Universal Lipoprotein(a) Screening: The Biggest New Idea
Every adult should now have their lipoprotein(a), or Lp(a), measured at least once in their lifetime. Lp(a) is an inherited cholesterol particle that raises heart-disease and stroke risk on its own, separate from your LDL. Because it is largely genetic, one test tells you your lifetime risk — you do not need to repeat it. Roughly one in five people has an elevated level and most never know it. This is the first time a major US guideline has recommended testing everyone, and it is the change most likely to affect people who look otherwise healthy.
Weight, Insulin Resistance, and Your Cholesterol
The 2026 guideline formally recommends losing at least 5% of your body weight if you have high cholesterol and are overweight. This matters because the typical cholesterol problem in insulin resistance and metabolic syndrome is not just high LDL — it is high triglycerides, low HDL, and small dense LDL particles. Losing weight improves all three. For people carrying extra weight, GLP-1 medications and dietary changes that lower fasting insulin often improve the whole lipid panel at once.
Who Needs a Statin Under the New Guideline
The 2026 guideline uses your PREVENT 10-year risk score, your LDL level, and your Lp(a) to decide on a statin. Statins are still first-line for most people at risk, but the new PREVENT calculator estimates risk differently than the old one — it adds kidney function and current statin use — so some people's risk scores will shift. If your LDL stays above goal on a statin, the guideline supports adding other drugs such as ezetimibe or a PCSK9 inhibitor. The practical takeaway: bring your latest numbers to your clinician and ask which tier you fall into.
What the 2026 Cholesterol Guidelines Mean for You
If your last cholesterol check predated 2026, three things are worth doing. Ask for an Lp(a) test if you have never had one — it is now recommended for everyone. Ask which LDL tier applies to you, since you now have a firm number to aim for. And if you carry extra weight, treat a 5% weight loss as part of the plan, not an afterthought.

Frequently Asked Questions
What are the new cholesterol guidelines for 2026?
The 2026 ACC/AHA dyslipidemia guideline replaced the 2018 cholesterol guideline. It restored numeric LDL-C goals based on risk (under 100, 70, or 55 mg/dL), recommended universal once-in-a-lifetime lipoprotein(a) screening for all adults, switched to the PREVENT risk calculator, and formally recommended at least 5% weight loss for people who are overweight with high cholesterol.
What should my LDL cholesterol be under the new guidelines?
Your LDL goal depends on your risk. For most healthy adults it is under 100 mg/dL. If you have risk factors or a prior heart event, the goal is under 70 mg/dL. For very-high-risk people with recent or multiple cardiovascular events, the goal is under 55 mg/dL. The 2026 guideline restored these specific numbers, which the 2018 version had dropped.
Why is lipoprotein(a) screening now recommended for everyone?
Lipoprotein(a), or Lp(a), is an inherited cholesterol particle that raises heart-disease and stroke risk independent of your LDL. Because it is largely genetic, a single test reveals your lifetime risk. About one in five people has an elevated level and most are unaware. The 2026 guideline recommends testing every adult once because it identifies hidden risk that standard cholesterol panels miss.
How is the 2026 cholesterol guideline different from 2018?
The 2018 guideline avoided firm LDL targets and focused mainly on LDL cholesterol. The 2026 guideline restores numeric LDL and non-HDL goals by risk, adds universal Lp(a) screening, uses the newer PREVENT risk calculator instead of the Pooled Cohort Equations, formally recommends weight loss, and expands its scope to cover high triglycerides and Lp(a).
