The American Heart Association's 2026 cholesterol guidelines push screening down to age 9 and ask doctors to combine family history, lab work and imaging to calculate each patient's own risk and treatment.
One in four Americans has unhealthy blood lipid levels. When cholesterol stays high for years, plaque builds up in the arteries, and blocked arteries mean heart attacks and strokes.
In 2026 the American Heart Association updated its treatment guidelines. The core message is simple: stop treating everyone the same way.
Harsher, and earlier
Doctors used to rely mainly on one number, LDL, the so-called bad cholesterol. The new version adds two blood tests.
One is ApoB, which counts how many plaque-forming particles are floating in the blood; LDL only weighs how much those particles mass together. For people with diabetes or metabolic syndrome, ApoB often explains risk better than LDL does.
The other is LpA, built like LDL but carrying an extra protein that makes it stickier. The guidelines say every adult should have it checked once in their life.
A third addition is a CT scan that measures calcium deposits in the arteries around the heart. More calcium means more risk.
Starting at age 9
The guidelines call for a lipid check at ages 9 to 11, then every five years from age 19. High-risk patients may start medication at 30.
Doctors are asked to follow four steps: calculate the patient's ten-year risk, layer on family history, lab results and existing conditions, reclassify with extra imaging if needed, and adjust treatment accordingly. An online calculator lets a 30-year-old see not just the next decade but the next 30 years.
Statins remain the workhorse drug. For patients who miss their targets or cannot tolerate the side effects, the guidelines list several newer classes that can be added.
The basics have not moved
Diet and exercise are still the foundation. The guidelines single out sugar, refined carbohydrates, saturated fat and alcohol as things to cut back. Aim for 150 minutes of moderate exercise a week, or 75 vigorous, plus two sessions of resistance training. Overweight patients should lose about 5 to 10 percent of their body weight.
What actually changed is how doctors do the math, not what the rest of us should do.
Why it matters
Answering the question of when to start medication with a set of personal numbers instead of an age means more people get labelled high-risk earlier and put on drugs sooner — and nobody yet knows how accurate that score really is.
