Personalized cholesterol testing decreases heart disease risk

Your Cholesterol, Updated:

What the New 2026 Heart Guidelines Mean for You

Summary by Catherine Batz, DO

Heart disease is still the leading cause of death in the U.S., and managing cholesterol is one of the most powerful ways to protect your heart. Earlier this year, the American College of Cardiology and American Heart Association released their first major cholesterol guideline update since 2018. Here's what's new, and what it means for your care.

Cholesterol Numbers Have Clear Targets Again

For several years, guidelines focused on the percentage your LDL (“bad”) cholesterol was lowered, rather than a specific number. Now your doctor has a clear target to aim for, based on your personal risk level:

Your Risk Level	LDL Goal
Lower risk	Below 100 mg/dL
Higher risk  (e.g., diabetes + risk factors, high 10-year score)	Below 70 mg/dL
Highest risk  (prior heart attack, stroke, or very high calcium score)	Below 55 mg/dL

A Better Way to Estimate Your Risk

Guidelines now recommend a newer, more accurate risk calculator called PREVENT, replacing the older Pooled Cohort Equations built on decades-old data. The PREVENT calculator:

• Modern data: built using data from over 3 million modern-day Americans

• Kidney function included: factors kidney health into your risk estimate

• Race removed: no longer uses race as a factor in the calculation

• Two time horizons: estimates both your 10-year and 30-year risk

• Wider age range: available for adults ages 30 to 79

Because PREVENT is more accurate, the risk threshold for considering medication has also shifted — your doctor may now use a 10-year risk of 3% or higher (instead of the old 7.5%) as a starting point for that conversation.

Start Thinking About Cholesterol Earlier

The longer your body is exposed to high cholesterol, the greater your lifetime risk of heart disease. That's why the guidelines recommend:

• Ages 9–11: cholesterol screening for all children (recommended by the American Academy of Pediatrics since 2011)

• Age 19+: a cholesterol panel at least every 5 years for young adults

• As early as age 30: consider cholesterol-lowering medication if LDL is ≥160 mg/dL, there's a strong family history of early heart disease, or a high 30-year risk score

Two New Blood Tests Worth Knowing About

Beyond the standard cholesterol panel, two additional blood tests can give a more complete picture of your heart disease risk.

Lipoprotein(a) — “Lp little a”

A cholesterol particle that's almost entirely genetic — you can't change it with diet or exercise, and a standard panel doesn't measure it. About 1 in 5 people have an elevated level, which raises heart disease risk by roughly 40% or more. Good news: you only need this test once in your life, fasting isn't required, and your level rarely changes.

Apolipoprotein B (apoB)

A standard test measures how much cholesterol is in your blood; apoB counts the actual number of harmful particles carrying it. The two numbers don't always match — your LDL may look fine while you still have too many harmful particles. This mismatch is especially common with diabetes, high triglycerides, or metabolic syndrome. ApoB is reasonable to check if you're already on cholesterol medication, particularly with diabetes, high triglycerides, or known heart disease, to confirm treatment is doing enough.

Statins Remain the Foundation — With More Options

Statins are still the first-choice medication for lowering cholesterol and preventing heart disease. The guidelines are more flexible about adding other medications earlier when needed:

• Ezetimibe (Zetia): a pill that blocks cholesterol absorption in the gut

• PCSK9 inhibitors (Repatha, Praluent): injectable medications that can dramatically lower LDL

• Bempedoic acid (Nexletol): a newer pill, especially helpful if you can't tolerate statins

Coronary Artery Calcium (CAC) Scoring Gets a Bigger Role

If you and your doctor are unsure whether you need medication, a coronary artery calcium scan — a quick, low-radiation CT of your heart — can help decide. The guidelines now tie specific LDL targets to your score:

CAC Score	What It Means
0	Reasonable to hold off on medication; recheck in 3–7 years
1–99	Moderate-intensity statin reasonable; goal LDL below 100
100+	Statin therapy recommended; goal LDL below 70
1,000+	Aggressive treatment recommended; goal LDL below 55

Lifestyle Still Comes First

No matter your risk level, a heart-healthy lifestyle remains the foundation:

• A diet rich in fruits, vegetables, lean proteins, whole grains, and healthy fats (or Mediterranean-style)

• At least 150 minutes per week of moderate aerobic activity

• Maintaining a healthy weight

• Not smoking

• Limiting alcohol

• Prioritizing sleep

• Minimizing stress

Dietary supplements are not recommended for lowering cholesterol — the evidence for benefit is limited and inconsistent.

What Should You Do Next?

1.  Ask if you've ever had your Lp(a) checked — if not, request it at your next visit.

2.  If you're on a statin, ask whether your LDL is at the new recommended goal for your risk level.

3.  If you're 40–75 and unsure about starting a statin, ask whether a coronary calcium scan could help with the decision.

These guidelines exist to help catch and treat cholesterol problems earlier and more precisely.
