Nuha El Sayed: Focused Summary of the 2026 ACC/AHA Guideline on Management of Dyslipidemia in Diabetes
Nuha El Sayed, Endocrinologist/ Diabetologist at Brigham and Women’s Hospital, Director, Guideline Development and Implementation Course at Harvard Medical School, shared a post on LinkedIn about a recent article by Roger S. Blumenthal et al, adding:
“Here is a focused summary of the brand-new 2026 ACC/AHA/Multisociety Guideline on the Management of Dyslipidemia actionable items for clinicians caring for people with diabetes:
Risk assessment
- Initiate LLT for all aged greater than or equal to 40 with DM, without needing to calculate 10-year ASCVD risk first.
- Switch to PREVENT-ASCVD equations (replacing the older Pooled Cohort Equations) for 10- and 30-year risk estimation in adults aged 30–79 for primary prevention decisions.
- Measure Lp(a) at least once in every patient’s lifetime, to support intensified preventive efforts.
LDL-C targets (reinstated)
LDL-C goals have returned to the guideline.
- Primary prevention, high risk (diabetes plus greater than or equal to 1 ASCVD risk factor): LDL-C less than 70 mg/dL
- Secondary prevention, very high risk (diabetes + established ASCVD): LDL-C less than 55 mg/dL
- Borderline/intermediate risk: LDL-C less than 100 mg/dL
Corresponding non-HDL-C goals are 30 points higher than each LDL-C target (i.e., less than 85, less than 100, less than 130 mg/dL respectively).
Pharmacotherapy algorithm
1. Maximize statin therapy first (high-intensity preferred, especially with ASCVD or high CV risk). Statins remain the cornerstone.
2. If LDL-C goal not achieved, add nonstatin therapy:
- Ezetimibe (generic, preferred first add-on)
- Bempedoic acid (oral, useful in statin-intolerant patients)
- PCSK9 monoclonal antibodies (for high/very-high-risk patients not at goal)
3. Inclisiran (siRNA, twice-yearly injection) may be considered for patients unable to tolerate or access PCSK9 inhibitors, though outcomes data are still pending.
ApoB: A new practical tool for diabetes
By incorporating apoB measurement, clinicians may better identify high-risk individuals who may otherwise be overlooked by traditional metrics.
- Measure apoB in those who have reached their LDL-C and non-HDL-C goals but have elevated triglycerides.
- ApoB targets: less than 55 mg/dL (very high risk), less than 70 mg/dL (high risk), less than 90 mg/dL (borderline–intermediate).
TGs levels of at least 150 mg/dL are associated with increased ASCVD risk, and levels are highly responsive to lifestyle intervention.
Lifestyle — still the foundation
Health behaviors such as body weight optimization, consistent physical activity, tobacco cessation, and adequate sleep hygiene form the foundational pillars of dyslipidemia management.
CAC scanning — A ‘tie breaker’
Coronary artery calcium testing recommendations have been strengthened, specifically for use as a ‘tie breaker’ when treatment is uncertain
Bottom line: The 2026 guideline takes a more aggressive, treat-to-goal approach than its 2018 predecessor.
For your patients with diabetes, the key shifts are: start LLT at 40, use PREVENT-ASCVD equations, target LDL-C to less than 70 mg/dL (primary prevention, high risk) or less than 55 mg/dL (with ASCVD), add apoB to guide intensification in those with high TGs, and escalate to PCSK9 inhibitors when targets aren’t met.”
