Dyslipidemia and statin therapy practical guide showing LDL-C targets and risk-based drug selection for adults — Overview of the risk-based approach to dyslipidemia management in adults.

1The 2026 ACC/AHA guideline restores absolute LDL-C goals: <55 mg/dL for very high-risk ASCVD, <70 mg/dL for high-risk and ASCVD, <100 mg/dL for primary prevention → What Are the New LDL-C Goals?
2The PREVENT-ASCVD equations replace the Pooled Cohort Equations for 10-year risk estimation, starting from age 30 → How to Assess Risk
3Measure lipoprotein(a) at least once in all adults — it is an independent, genetically determined ASCVD risk factor → What About Lp(a)?
4High-intensity statin therapy (atorvastatin 40–80 mg or rosuvastatin 20–40 mg) should achieve at least 50% LDL-C reduction → Choosing the Right Statin
5When LDL-C remains above goal on maximally tolerated statin, add ezetimibe first, then a PCSK9 inhibitor or bempedoic acid → Nonstatin Add-On Therapy
6Start high-intensity statin immediately for LDL-C ≥190 mg/dL without needing risk calculation → Special Populations
7Adults aged 40–75 with diabetes should receive at least moderate-intensity statin therapy; use high-intensity if additional risk factors are present → Special Populations
8Coronary artery calcium scoring now has structured LDL-C goal tiers: CAC 0 may defer therapy; CAC ≥300 targets <55 mg/dL → How to Assess Risk
9True statin intolerance is uncommon — rechallenge with a different statin, lower dose, or alternate-day dosing before declaring failure → Managing Statin Intolerance
10Check lipids 4–12 weeks after starting or changing therapy, then every 6–12 months to assess response and adherence → Monitoring

What Are the New LDL-C Goals?

The 2026 ACC/AHA guideline marks a major shift by restoring absolute LDL-C treatment goals — a change from the 2018 guideline, which focused primarily on percentage reductions. Both percentage reduction and absolute goals now guide treatment decisions. The principle is straightforward: the higher the cardiovascular risk, the lower the LDL-C target.

Target LDL-C below 55 mg/dL (1.4 mmol/L) for patients with clinical ASCVD at very high risk. Very high risk is defined as two or more major ASCVD events, or one major event plus two or more high-risk features (age ≥65, diabetes, hypertension, current smoking, HF history, LDL-C ≥100 mg/dL on maximal statin plus ezetimibe, prior CABG/PCI).

Strong Rec High Evidence ACC/AHA 2026

Target LDL-C below 70 mg/dL (1.8 mmol/L) for patients with clinical ASCVD not at very high risk, and for high-risk primary prevention patients including those with diabetes and additional risk factors or 10-year ASCVD risk ≥20%.

Strong Rec High Evidence ACC/AHA 2026 ESC/EAS 2019

Target LDL-C below 100 mg/dL (2.6 mmol/L) for primary prevention patients at borderline or intermediate 10-year risk (PREVENT-ASCVD risk 3–10%) who are initiated on lipid-lowering therapy. For those at high risk (>10%), the target is below 70 mg/dL.

Moderate Rec Moderate Evidence ACC/AHA 2026

Prescribe high-intensity statin therapy immediately for adults with LDL-C ≥190 mg/dL (≥4.9 mmol/L), regardless of calculated risk. These patients likely have familial hypercholesterolaemia and should be evaluated and referred accordingly. Target a reduction of at least 50%.

Strong Rec High Evidence ACC/AHA 2026 ESC/EAS 2019

Clinical Pearl: The restoration of absolute LDL-C goals in the 2026 ACC/AHA guideline brings US recommendations closer to the ESC/EAS approach, which has used absolute targets since 2019 (also <55 mg/dL for very high risk). The key clinical implication: you now need to check whether your patients have reached a specific LDL-C number, not just whether the percentage dropped enough. This changes follow-up conversations and may trigger earlier nonstatin add-on therapy.

How Should You Assess Cardiovascular Risk?

Risk assessment drives treatment intensity. The 2026 ACC/AHA guideline introduces a new framework: Calculate risk with the PREVENT-ASCVD equations, Personalise using risk-enhancing factors, and Reclassify with coronary artery calcium (CAC) scoring when the decision is uncertain (the CPR framework).

Perform 10-year ASCVD risk estimation using the AHA PREVENT-ASCVD equations for adults aged 30–79. These replace the Pooled Cohort Equations and include kidney function and HbA1c as inputs, improving calibration across diverse populations.

Strong Rec Moderate Evidence ACC/AHA 2026

Measure lipoprotein(a) at least once in all adults to identify those with genetically elevated levels. Elevated Lp(a) (≥50 mg/dL or ≥125 nmol/L) is an independent ASCVD risk factor and should be considered a risk-enhancing factor that may favour more aggressive LDL-C lowering.

Strong Rec Moderate Evidence ACC/AHA 2026

Consider coronary artery calcium (CAC) scoring in adults at borderline or intermediate risk (PREVENT-ASCVD 3–20%) when the statin decision is uncertain after reviewing risk-enhancing factors. A CAC score of zero may allow deferring statin therapy (unless the patient smokes, has diabetes, or a strong family history of premature ASCVD). CAC ≥100 favours statin initiation with an LDL-C goal below 70 mg/dL; CAC ≥300 favours a goal below 55 mg/dL.

Moderate Rec Moderate Evidence ACC/AHA 2026

How to Choose the Right Statin and Dose

Statin therapy is classified by the expected percentage LDL-C reduction. High-intensity statins lower LDL-C by 50% or more; moderate-intensity by 30–49%. The CTT meta-analysis established that each 1 mmol/L (38.7 mg/dL) reduction in LDL-C reduces ASCVD events by roughly 21%.

Statins and Nonstatin LDL-Lowering Agents: A Drug-by-Drug Guide

Drug	Expected LDL-C Reduction	Intensity Class	Key Interactions	Practical Tips
Atorvastatin 40–80 mg	≥50%	High	CYP3A4 inhibitors (clarithromycin, itraconazole, protease inhibitors)	Can be taken any time of day. No dose adjustment for renal impairment. Most widely used high-intensity statin.
Rosuvastatin 20–40 mg	≥50%	High	Fewer CYP interactions than atorvastatin; caution with ciclosporin, gemfibrozil	Slightly greater LDL-C lowering mg-for-mg than atorvastatin. Start at 10–20 mg in Asians. Reduce dose in severe renal impairment.
Atorvastatin 10–20 mg	30–49%	Moderate	Same as high-dose atorvastatin	Suitable starting dose for primary prevention at intermediate risk.
Rosuvastatin 5–10 mg	30–49%	Moderate	Same as high-dose rosuvastatin	Good option when fewer drug interactions are needed.
Ezetimibe 10 mg	~18–20% additional	Nonstatin add-on	No significant interactions	First-line add-on when LDL-C not at goal on statin. Inexpensive and well tolerated. IMPROVE-IT showed CV outcome benefit in ACS patients.
PCSK9 inhibitors (evolocumab, alirocumab)	~50–60% additional	Nonstatin add-on	No significant drug interactions	Subcutaneous injection every 2–4 weeks. FOURIER and ODYSSEY showed CV outcome benefit in ASCVD patients. High cost limits use to highest-risk patients.
Bempedoic acid 180 mg	~21% (alone); ~38% with ezetimibe FDC	Nonstatin (oral)	May raise uric acid; monitor in gout. Increases statin levels — do not use with simvastatin >20 mg or pravastatin >40 mg.	Oral, once daily. CLEAR Outcomes showed 13% MACE reduction in statin-intolerant patients. Useful alternative for patients who truly cannot take statins.
Inclisiran 284 mg	~50% additional	Nonstatin (siRNA)	No significant interactions	Subcutaneous injection twice yearly after initial doses. Highly convenient. CV outcomes data from ORION-4 trial are pending at time of writing.

Do not initiate simvastatin 80 mg in new patients due to increased myopathy risk.
Verify all doses against local formulary. Adjust for renal/hepatic impairment and drug interactions.

Warning

Statins are contraindicated in pregnancy and should be stopped at least 3 months before planned conception. The 2026 guideline also notes that statins slightly increase the risk of new-onset diabetes in patients with prediabetes, but this risk is far outweighed by the cardiovascular benefit. Do not discontinue statin therapy for this reason.

Clinical Pearl: True statin intolerance is uncommon. Nocebo effect accounts for a significant proportion of reported muscle symptoms. Before concluding intolerance, try: switching to a different statin, using a lower dose, or dosing rosuvastatin or atorvastatin on alternate days (their long half-lives support this). Bempedoic acid is now a proven oral alternative for patients with genuine intolerance.

Clinical Decision Pathway

Lipid Management in Adults: 5 Questions

Question 1: Does this patient have clinical ASCVD?

Yes → Start high-intensity statin. If very high risk, target LDL-C <55 mg/dL. If not very high risk, target <70 mg/dL. Add ezetimibe if not at goal, then PCSK9 inhibitor if still above threshold.

No → Go to Question 2.

Question 2: Is LDL-C ≥190 mg/dL?

Yes → High-intensity statin without risk calculation. Evaluate for familial hypercholesterolaemia. Add ezetimibe and PCSK9 inhibitor as needed to achieve at least 50% reduction.

No → Go to Question 3.

Question 3: Does the patient have diabetes (age 40–75)?

Yes → At least moderate-intensity statin. Target LDL-C <70 mg/dL if additional risk factors present (long duration, albuminuria, retinopathy, neuropathy, ABI <0.9). High-intensity statin for those aged 50–75 with multiple risk factors.

No → Go to Question 4.

Question 4: What is the 10-year PREVENT-ASCVD risk?

<3% (low) → Lifestyle therapy. Reassess in 5 years.

3–<5% (borderline) → LDL-lowering therapy may be considered; use risk enhancers and shared decision-making. Target LDL-C <100 mg/dL.

5–10% (intermediate) → Moderate-intensity statin recommended. If decision uncertain, consider CAC scoring. Target LDL-C <100 mg/dL.

>10% (high) → Moderate- to high-intensity statin. Target LDL-C <70 mg/dL.

Question 5: Is LDL-C at goal after 4–12 weeks?

Yes → Continue current regimen. Recheck lipids every 6–12 months. Reinforce lifestyle and adherence.

No → Assess adherence first. Maximise statin dose. Add ezetimibe. If still not at goal and high/very high risk, add PCSK9 inhibitor or bempedoic acid.

Monitoring and Follow-Up

Parameter	When	Action Threshold	Common Pitfalls
Lipid panel	4–12 weeks after starting or changing therapy; then every 6–12 months	LDL-C above individualised goal → intensify therapy	Therapeutic inertia: not adding ezetimibe or PCSK9i when LDL-C is above goal on statin
ALT	Baseline before statin initiation; not routinely needed thereafter unless symptoms arise	ALT >3× ULN → hold statin and investigate	Routine serial LFT monitoring on statins is unnecessary and adds cost without benefit
CK	Only if muscle symptoms develop; not routinely needed at baseline	CK >10× ULN with symptoms → stop statin	Ordering routine CK creates anxiety and leads to unnecessary discontinuation
Lp(a)	Once in a lifetime (genetically determined, stable)	≥50 mg/dL or ≥125 nmol/L → classify as risk-enhancing factor	Never checking it at all — many clinicians are unfamiliar with Lp(a) but the 2026 guideline recommends universal screening

Evidence in Context

What Changed From 2018 to 2026?

The 2026 ACC/AHA guideline introduces several landmark changes: restoration of absolute LDL-C goals (previously dropped in 2013), adoption of the PREVENT-ASCVD risk calculator replacing the Pooled Cohort Equations, universal Lp(a) screening, expanded CAC scoring guidance with goal-specific tiers, and incorporation of five new FDA-approved lipid-lowering therapies (bempedoic acid, bempedoic acid/ezetimibe FDC, inclisiran, evinacumab, and lomitapide for HoFH). The guideline is also retitled from “Blood Cholesterol” to “Dyslipidemia” to reflect its broader scope including triglycerides and Lp(a).

Where ACC/AHA 2026 and ESC/EAS 2019 Now Agree

The two frameworks are now more closely aligned than ever. Both recommend absolute LDL-C goals: <55 mg/dL for very high-risk ASCVD and <70 mg/dL for high-risk patients. Both support the stepwise addition of ezetimibe then PCSK9 inhibitors when goals are not met. Both recommend Lp(a) measurement. The main remaining differences are in risk calculators (PREVENT-ASCVD vs SCORE2) and some specifics of primary prevention thresholds.

Key Trial Evidence Behind the Recommendations

The CTT Collaboration meta-analysis of 26 statin trials established that each 1 mmol/L LDL-C reduction produces a roughly 21% reduction in major vascular events. IMPROVE-IT demonstrated that adding ezetimibe to simvastatin after ACS reduced MACE by a further 6.4% relative risk over a median of 6 years. FOURIER showed evolocumab reduced MACE by 15% in stable ASCVD patients on statins. ODYSSEY OUTCOMES showed alirocumab reduced MACE by 15% in post-ACS patients. CLEAR Outcomes showed bempedoic acid reduced MACE by 13% in statin-intolerant patients. Together, these trials support the principle that “lower for longer is better” for LDL-C.

What We Still Don’t Know

Lp(a)-lowering therapies: Lp(a) is a causal risk factor, but dedicated Lp(a)-lowering agents (e.g., pelacarsen, olpasiran) are still in phase 3 trials. Until outcome data are available, elevated Lp(a) is managed by intensifying LDL-C lowering, not by directly targeting Lp(a).

Inclisiran cardiovascular outcomes: Inclisiran powerfully lowers LDL-C with convenient twice-yearly dosing, but the ORION-4 CV outcome trial results are still pending at the time of writing.

How low can LDL-C safely go? Trials have achieved LDL-C levels below 20 mg/dL without apparent safety signals, but very long-term data at ultra-low levels remain limited.
