ACC/AHA 2026 Dyslipidemia Guidelines
A practical clinician summary of risk assessment, LDL-C targets, Lp(a), CAC, and modern lipid management
What changed in 2026:
- LDL-C treatment goals return and guide therapy
- PREVENT replaces traditional risk calculators
- Lp(a) recommended at least once in all adults
- CAC used to reclassify risk and guide decisions
In 30 Seconds — What Changed?
PREVENT replaces PCE and improves individualised risk estimation
Earlier, lower, and longer LDL-C reduction
Clear LDL-C and non-HDL-C goals return, especially in high-risk patients
Lp(a) measured once in all adults; ApoB used selectively
CAC scoring can reclassify risk when the treatment decision is uncertain
Broader focus beyond LDL-C, including triglycerides and lifetime risk
Key Shift in 2026
This guideline represents a shift from treating numbers to treating lifetime cardiovascular risk.
What Changed in 2026
Key practice updates from the 123-page guideline — what every clinician needs to know.
10 Top Take-Home Messages
Treat earlier. Lifestyle counselling from youth. Pharmacotherapy in youth with FH and young adults with LDL-C ≥160 mg/dL (4.1 mmol/L) or strong family Hx premature ASCVD.
PREVENT™ replaces PCE for 10- and 30-year risk. Use the CPR Model: Calculate → Personalise → Reclassify with CAC.
Borderline risk starts at 3%. LLT can be considered at PREVENT 3–<5% and should be considered at 5–<10%.
Treatment goals are back. LDL-C and non-HDL-C absolute targets now guide therapy alongside percentage LDL-C reduction.
ApoB for residual risk. Useful once LDL-C/non-HDL-C goals met, especially with elevated TG, diabetes, or achieved LDL-C <70.
Lp(a) at least once in all adults. ≥125 nmol/L / 50 mg/dL (~1.4× risk). ≥250 nmol/L / 100 mg/dL (≥2× risk). If elevated, intensify LDL-C lowering and manage other modifiable risk factors.
CAC for reclassification. Men ≥40, women ≥45. CAC >0 → initiate LLT. CAC ≥100 or ≥75th %ile → high-intensity. CAC 0 → may defer.
LLT for diabetes, CKD 3-4, HIV regardless of LDL-C in adults 40-75. After 75, consider with shared decision-making.
Very-high-risk ASCVD: LDL-C <55 mg/dL (1.4 mmol/L), non-HDL-C <85 mg/dL (2.2 mmol/L). Ezetimibe no longer required before PCSK9 mAb. Bempedoic acid added.
Hypertriglyceridemia: Statin first-line for ASCVD risk. TG-lowering for pancreatitis prevention especially TG ≥1000.

Risk Assessment Framework
The CPR model replaces the old PCE-driven approach. Start with PREVENT, then personalise.
Calculate
Use PREVENT-ASCVD for 10-year risk in adults 30–79 y without ASCVD.
Personalise
Consider risk enhancers not captured by PREVENT.
Reclassify
Use CAC scoring when LLT decision uncertain.
PREVENT vs PCE
PREVENT-ASCVD estimates are 40–50% lower than PCE for the same profile. The new borderline threshold (≥3%) identifies a similar number of adults eligible for LLT (~25 million US adults). Inputs: age, sex, BP, TC, HDL-C, DM, tobacco, eGFR, statin use, antihypertensive use. Optional: HbA1c, UACR, zip code.
Biomarkers & Testing
What to measure, when, and what each test adds.
Standard Lipid Profile
TC, LDL-C, HDL-C, TG, non-HDL-C. Screen from age 19 y. Children 9–11 y.
ApoB
Atherogenic particle number. Superior when LDL-C and apoB discordant.
Lp(a)
Genetically determined. Measure once. Minimally affected by lifestyle/LLT.
CAC Score
Men ≥40, women ≥45. Absolute score + percentile both prognostic.
Treatment Goals by Risk Category
Based on Figure 1. Both absolute goals and percentage LDL-C reduction guide therapy.
| Patient Category | % LDL-C ↓ | LDL-C Goal mg/dL (mmol/L) | Non-HDL-C Goal mg/dL (mmol/L) | ApoB |
|---|---|---|---|---|
| ASCVD — Very High Risk | ≥50% | <55 (1.4) | <85 (2.2) | <55 |
| ASCVD — Not Very High Risk | ≥50% | <70 (1.8) | <100 (2.6) | Consider |
| Severe Hypercholest. + HeFH / Risk / CAC | ≥50% | <70 (1.8) | <100 (2.6) | — |
| Severe Hypercholest. (no additional risk) | Max tolerated | <100 (2.6) | <130 (3.4) | — |
| Diabetes + Multiple Risk Factors | ≥50% | <70 (1.8) | <100 (2.6) | Consider |
| Diabetes (40–75 y, no ASCVD) | ≥30–49% | <100 (2.6) | <130 (3.4) | — |
| CAC ≥1000 AU | ≥50% | <55 (1.4) | <85 (2.2) | — |
| CAC 100–999 or ≥75th %ile | ≥50% | <70 (1.8) | <100 (2.6) | — |

| Primary Prev. — High (≥10%) | ≥50% | <70 (1.8) | <100 (2.6) | — |
| Primary Prev. — Intermediate (5–<10%) | ≥30–49% | Individualise | Individualise | — |
| Primary Prev. — Borderline (3–<5%) | ≥30–49% | Individualise | Individualise | — |
All values in mg/dL with mmol/L in parentheses. Non-HDL-C ≈ LDL-C goal + 30 mg/dL (0.8 mmol/L).
| High-Intensity (≥50% ↓) | Moderate (30–49% ↓) | Low (<30% ↓) |
|---|---|---|
| Atorvastatin 40–80 mg Rosuvastatin 20–40 mg | Atorvastatin 10–20 mg Rosuvastatin 5–10 mg Simvastatin 20–40 mg Pravastatin 40–80 mg Lovastatin 40 mg Fluvastatin XL 80 mg Pitavastatin 1–4 mg | Simvastatin 10 mg Pravastatin 10–20 mg Lovastatin 20 mg Fluvastatin 20–40 mg |
Nonstatins + low/moderate statin can achieve ≥50% LDL-C ↓. East Asian ancestry may need lower starting doses.
Management Pathways
Select a patient profile for a concise decision pathway.
Primary Prevention — Adults 30–79 y, LDL-C 70–189 mg/dL (1.8–4.9 mmol/L)
Severe Hypercholesterolaemia — LDL-C ≥190 mg/dL (4.9 mmol/L)
Diabetes — Adults Without Established ASCVD
Clinical ASCVD — Secondary Prevention
Very High Risk (majority of ASCVD)
≥2 major ASCVD events OR 1 major event + ≥2 high-risk conditions
Not Very High Risk
Does not meet very-high-risk criteria above
Subclinical Coronary Atherosclerosis — CAC-Based Management
Hypertriglyceridemia Management
Lifestyle Foundation
AHA Life's Essential 8. Lifelong from youth. ~50% RRR even with genetic predisposition.
LDL-C Lowering Lifestyle
TG Lowering Lifestyle (by range)

Monitoring & Follow-Up
Assess response, adherence, and safety at defined intervals.
Baseline
Fasting or nonfasting lipid profile. Assess ASCVD risk. Initiate lifestyle ± pharmacotherapy. Measure Lp(a) once.
4–12 Weeks Post-Initiation
COR 1: Repeat lipid profile. Assess % LDL-C ↓ and absolute goals. Evaluate adherence. Nonfasting adequate unless hypertriglyceridemia. Inadequate → intensify.
Every 6–12 Months
Individualise frequency. Stable patients → annual testing. Monitoring improves adherence and reduces therapeutic inertia.
Ongoing Safety
• Routine CK: NOT useful (COR 3)
• Routine LFTs: NOT required (FDA 2012)
• CoQ10: NOT recommended (COR 3)
• DDI screening: COR 1 — especially CYP3A4 statins
• Statin → T2DM risk: Do NOT discontinue
| Interaction | Statins | Action |
|---|---|---|
| Protease inhibitors (ritonavir, cobicistat) | Lovastatin, simvastatin | Contraindicated |
| Protease inhibitors | Atorvastatin | Max 20 mg/day |
| Azole antifungals (itraconazole, ketoconazole) | Lovastatin, simvastatin | Contraindicated |
| Cyclosporine | Lovastatin, simvastatin, pitavastatin | Contraindicated |
| Amiodarone, dronedarone | Simvastatin | Max 20 mg/day |
| Verapamil, diltiazem | Lovastatin, simvastatin | Max 20 mg/day |

| Gemfibrozil | All statins | Avoid; use fenofibrate |
Pravastatin avoids CYP450. Pitavastatin (PLHIV preferred) avoids CYP3A4. Rosuvastatin/fluvastatin use CYP2C9.
