Advanced Lipid Panel Interpreter
2026 ACC/AHA Dyslipidemia Guideline implementation. Calculate, Personalize, Reclassify. PREVENT-ASCVD risk scoring with interactive intervention modeling.
~2.5 nmol/L per 1 mg/dL
The 2026 guideline recommends ApoB over LDL-P for clinical decision-making. LDL-P is shown for reference.
PREVENT is for primary prevention only. If the patient has established ASCVD, check the box above instead.
Don't know your eGFR? It's calculated from creatinine on a metabolic panel.
Enter lipid panel values and complete the risk assessment above for personalized targets.
These interventions reduce cholesterol production in the liver. Select one.
These interventions reduce cholesterol absorbed from the gut.
These interventions increase the liver's clearance of LDL particles from the blood.
Active interventions are highlighted where they act on the pathway.
How this works
This tool implements the 2026 ACC/AHA Dyslipidemia Guideline's CPR framework: Calculate risk with the PREVENT-ASCVD equations, Personalize with risk-enhancing factors, Reclassify with coronary artery calcium scoring.
PREVENT replaces the old Pooled Cohort Equations, which overestimated 10-year risk by 40-50% in modern populations. PREVENT is sex-specific, race-free, and incorporates kidney function and BMI. The PREVENT model uses a logistic regression framework with piecewise linear splines for systolic blood pressure (knot at 110 mmHg), eGFR (knot at 60 mL/min), and BMI (knot at 30 kg/m²), plus age-interaction terms for most predictors.
LDL-C is calculated three ways. Most US labs still report Friedewald (1972), which divides triglycerides by a fixed factor of 5. The Sampson-NIH equation (2020) uses a regression model that remains accurate at much higher triglyceride levels. When triglycerides are elevated, these equations diverge, and Friedewald systematically underestimates LDL-C, which means some patients appear to be at goal when they are not.
ApoB measures the number of atherogenic particles directly. Each LDL, VLDL, IDL, and Lp(a) particle carries exactly one ApoB molecule. When LDL-C looks normal but ApoB is elevated, the patient has more small, dense particles than the cholesterol content suggests. The 2026 guideline recommends ApoB measurement and provides numeric targets aligned with LDL-C categories.
The ancestral LDL-C baseline. Hunter-gatherer populations, healthy human neonates, free-living primates, and wild mammals maintain LDL-C levels of 50-70 mg/dL and do not develop atherosclerosis. The Tsimane of Bolivia, a forager-horticulturalist population, have a mean LDL of 91 mg/dL and the lowest reported prevalence of coronary atherosclerosis of any population studied. The modern Western average of 110-130 mg/dL is approximately double the ancestral baseline. Every intervention in this tool, whether cooking with whole foods, adding fiber, walking after dinner, or taking rosuvastatin, is moving the needle back toward where human biology expects it to be.
Interventions are organized by mechanism, not by "pharmaceutical vs natural." Red yeast rice and lovastatin are the same molecule acting on the same enzyme. Ezetimibe and plant sterols both reduce intestinal cholesterol absorption through overlapping mechanisms. The clinical question is not "drug or supplement" but "which combination closes the gap between where you are and where your body needs to be, given your risk and your values."
The stacking model uses multiplicative reduction because each successive intervention acts on a smaller remaining pool of LDL-C. A statin that reduces LDL-C by 50% plus ezetimibe that reduces the remainder by 23% yields a total reduction of about 62%, not 73%.
Low LDL-C achieved through treatment is safe for the brain. The brain synthesizes virtually all of its own cholesterol behind the blood-brain barrier; circulating LDL does not cross it in meaningful quantities. The largest meta-analysis to date (55 studies, 7+ million patients) found statin use associated with a 14% reduction in dementia risk. Participants in clinical trials with LDL-C below 25 mg/dL showed no cognitive decline.
