Lifestyle Foundation
Built on AHA Life's Essential 8 and applied lifelong from youth — capable of roughly 50% relative risk reduction even with genetic predisposition.
LDL-C lowering lifestyle
- Mediterranean, DASH or vegetarian patterns — fruit, vegetables, nuts, legumes, whole grains and fibre
- Replace saturated and trans fats with mono- and polyunsaturated fats
- ≥150 min/week moderate-vigorous activity plus resistance training ≥2 days/week
- Healthy weight and tobacco cessation
- Dietary supplements are not recommended for LDL-C lowering (COR 3)

Triglyceride lowering (by range)
- TG 150–499 mg/dL (1.7–5.6 mmol/L): reduce sugar, refined carbohydrate and saturated fat; minimise alcohol; physical activity.
- TG 500–999 mg/dL (5.7–11.3 mmol/L): add no alcohol and individualised fat limitation; refer to a dietitian (COR 2a).
- TG ≥1000 mg/dL (11.3 mmol/L): mandatory dietitian referral (COR 1), strict fat restriction, exclude familial chylomicronaemia syndrome.
Triggers: alcohol, sugar and refined carbohydrate, uncontrolled diabetes, hypothyroidism, obesity, corticosteroids, oestrogens, retinoids and antiretrovirals.
Special Populations
When standard pathways need tailoring. Tap to expand.
Children & adolescents
Screen 9–11 y (COR 1); cascade from ≥2 y if family history. About 20% of adolescents have lipid abnormalities and roughly 1 in 250 have HeFH; family history alone misses about half. Early pharmacotherapy for FH.
Pregnancy & lactation
Statins, PCSK9 mAbs, bempedoic acid and ezetimibe are contraindicated; colesevelam is the safest option. Reproductive risk markers are ASCVD risk enhancers.
CKD stage 3+
Moderate statin ± ezetimibe for CKD 3+ with LDL-C 70–189 mg/dL (1.8–4.9 mmol/L) (COR 1, SHARP). With ASCVD: high-intensity statin to LDL-C <55 (1.4), non-HDL-C <85 (2.2). On dialysis, initiating a statin is not beneficial though continuing may be reasonable. Atorvastatin preferred; rosuvastatin ≤10 mg in severe CKD.
HIV (people living with HIV)
Pitavastatin 4 mg for adults 40–75 y on stable ART (COR 1; REPRIEVE showed a 35% MACE reduction). Not metabolised by CYP3A4. Lovastatin and simvastatin are contraindicated with protease inhibitors.
Elevated Lp(a)
A risk enhancer rather than a direct treatment target with current therapies. If elevated, intensify LDL-C lowering and manage all other modifiable risk factors aggressively. Novel Lp(a)-lowering agents (pelacarsen, olpasiran, lepodisiran) are in phase 3 trials but not yet available. Lp(a) overview →
Older adults (>75 y)
Primary prevention: LLT may be considered where life expectancy is ≥2.5 y. Continue an existing statin — discontinuation increases heart-failure hospitalisation and cardiovascular events.
Statin-associated muscle symptoms (SAMS)
About 10% are intolerant. Try an alternative statin or reduce the dose; bempedoic acid (COR 1), ezetimibe and PCSK9 mAbs are options. CoQ10 is not recommended (COR 3); routine CK is not useful (COR 3); routine LFTs are no longer required.
Cancer survivors & chronic inflammatory disease
Cancer: continue LLT — statins may protect against anthracycline cardiotoxicity. Chronic inflammatory disease: standard calculators underestimate risk, so it is treated as a risk enhancer; monitor lipids on anti-inflammatory therapy.
Monitoring & Follow-Up
Assess response, adherence and safety at defined intervals.
Baseline
Before therapy
Fasting or non-fasting lipid profile, ASCVD risk assessment, lifestyle ± pharmacotherapy. Measure Lp(a) once.
COR 1
4–12 weeks post-initiation
Repeat lipid profile; assess percentage LDL-C reduction, absolute goals and adherence. Non-fasting adequate unless hypertriglyceridaemia. Inadequate response → intensify.
Ongoing
Every 6–12 months
Individualise frequency; stable patients annually. Monitoring improves adherence and reduces therapeutic inertia.
Safety
Ongoing safety
Routine CK not useful (COR 3); routine LFTs not required; CoQ10 not recommended (COR 3); screen drug interactions (COR 1), especially CYP3A4 statins. Statin-related T2DM risk: do not discontinue.
Safety — CYP3A4 statin drug interactions
| 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 |
| Ticagrelor | Simvastatin | Max 40 mg/day |
| Gemfibrozil | All statins | Avoid; use fenofibrate |
Pravastatin avoids CYP450; pitavastatin (preferred in HIV) avoids CYP3A4; rosuvastatin and fluvastatin use CYP2C9.

Level of evidence

Frequently Asked Questions
What is the PREVENT risk calculator and why does it replace the PCE?
The AHA PREVENT-ASCVD equations are a more contemporary tool that replaces the older Pooled Cohort Equations for 10- and 30-year cardiovascular risk in adults 30–79 y. PREVENT estimates run 40–50% lower than the PCE for the same profile, but the lower thresholds (borderline from ≥3%) identify a similar number of adults who may benefit from therapy. It adds inputs such as eGFR and statin use, with optional HbA1c, urine albumin-to-creatinine ratio and a social deprivation index. Try our PREVENT calculator →
What LDL-C level should I aim for?
Targets depend on risk category. For established ASCVD at very high risk the goal is LDL-C <55 mg/dL (1.4 mmol/L) and non-HDL-C <85 mg/dL (2.2 mmol/L); for ASCVD not at very high risk it is LDL-C <70 mg/dL (1.8 mmol/L). For primary prevention with diabetes or multiple risk factors the goal may be <70 or <100 mg/dL (2.6 mmol/L) depending on risk. In all cases a percentage LDL-C reduction of ≥30–50% is also a treatment objective. Cholesterol unit converter →
Should everyone have their Lp(a) tested?
The guideline gives a Class 1 recommendation for Lp(a) measurement at least once in all adults. Lp(a) is largely genetically determined and is not meaningfully lowered by lifestyle or standard therapy. If elevated (≥125 nmol/L or 50 mg/dL) it is a risk-enhancing factor that should prompt more aggressive LDL-C lowering and management of other modifiable risk factors. It is not a direct treatment target with currently available therapies, though novel agents are in late-stage trials. Read our Lp(a) overview →
When should a coronary artery calcium (CAC) score be used?
CAC scoring is recommended (COR 1) in adults at intermediate risk (5–<10%) and selected adults at borderline risk (3–<5%) when the decision about therapy remains uncertain after a clinician–patient discussion. It is a selective reclassification tool, not a universal test. CAC 0 with no other high-risk conditions may allow deferral with repeat testing in 3–7 y; CAC >0, particularly ≥100 AU or ≥75th percentile, should prompt therapy. Learn about calcium scoring →
What role does ApoB play in the 2026 guideline?
ApoB is not recommended universally but has been elevated in importance (COR 2a). It is most useful in adults already on therapy — particularly with ASCVD, CKM syndrome, type 2 diabetes or elevated triglycerides — where LDL-C may underestimate the true atherogenic particle burden. It helps identify residual risk after LDL-C and non-HDL-C goals are met and guides further intensification. It is unaffected by fasting and especially valuable when LDL-C and ApoB are discordant. Learn more about ApoB →
Are dietary supplements effective for lowering cholesterol?
No. The guideline gives a Class 3 (no benefit) recommendation for dietary supplements for LDL-C or triglyceride lowering, citing limited and inconsistent data — including fish-oil supplements, red yeast rice and plant sterols as routine ASCVD risk-reduction strategies. Evidence-based pharmacotherapy (statins, ezetimibe, PCSK9 mAbs, bempedoic acid) remains the standard of care when lifestyle alone is insufficient.
How often should lipids be checked on treatment?
A lipid profile should be repeated 4–12 weeks after starting or adjusting therapy and every 6–12 months thereafter (COR 1). Non-fasting testing is adequate in most cases unless hypertriglyceridaemia is known. Regular monitoring assesses both percentage LDL-C reduction and achievement of absolute goals, improves adherence and reduces therapeutic inertia.
