You Are Not Just Chasing Numbers—Further Risk Reduction Is Achievable and Beneficial
Even when a patient is on high-intensity statin therapy with LDL-C near target, adding nonstatin therapies provides meaningful cardiovascular risk reduction, particularly in very high-risk patients. This is not merely "chasing numbers"—it's reducing morbidity and mortality.
The Evidence Against "Just Chasing Numbers"
The concept that achieving LDL-C goals on high-intensity statins represents the ceiling of benefit has been definitively refuted:
- For patients with clinical ASCVD at very high risk on maximally tolerated statin therapy with LDL-C ≥70 mg/dL, adding ezetimibe reduces major adverse cardiovascular events (MACE) 1
- The 2022 ACC Expert Consensus recommends a lower LDL-C threshold of ≥55 mg/dL (or non-HDL-C ≥85 mg/dL) for considering nonstatin therapies in very high-risk patients, reflecting evidence that individuals achieving LDL-C <55 mg/dL experience lower event rates than those with higher levels 1
- There appears to be no LDL-C level below which cardiovascular benefit ceases—lifelong very low LDL-C levels (15-30 mg/dL) in patients with genetic conditions and in clinical trials show lower ASCVD incidence without adverse effects 1
The Log-Linear Relationship: Every Point Counts
The relationship between LDL-C and cardiovascular risk is log-linear without an apparent threshold:
- For every 1% reduction in LDL-C levels, relative risk for major coronary events is reduced by approximately 1%, and this relationship holds even for LDL-C levels below 100 mg/dL 1
- Recent trials did not identify a threshold LDL-C level below which no further reduction in risk occurs 1
- Reducing LDL-C by 30% starting at 100 mg/dL produces another 20-30% lowering in relative risk for coronary heart disease 1
Defining "Very High Risk" Patients Who Benefit Most
Not all patients require aggressive add-on therapy, but very high-risk patients clearly benefit:
Very high-risk characteristics include 1:
- History of multiple major ASCVD events
- One major ASCVD event plus multiple high-risk conditions
- Recent acute coronary syndrome (within 2 years)
- Baseline LDL-C ≥190 mg/dL with clinical ASCVD
- Diabetes with additional cardiovascular risk factors
For these patients, intensive LDL lowering to <70 mg/dL (and consideration of <55 mg/dL) is supported by outcomes data, not arbitrary number-chasing 1.
Practical Treatment Algorithm for Patients Already on High-Intensity Statins
Step 1: Verify Optimal Statin Therapy
- Confirm the patient is on maximally tolerated high-intensity statin therapy (atorvastatin 40-80 mg or rosuvastatin 20-40 mg) 1
- Assess adherence to medications and lifestyle modifications 1
- Exclude secondary causes of hyperlipidemia (hypothyroidism, nephrotic syndrome, medications) 1
Step 2: Risk Stratification
If the patient has clinical ASCVD at very high risk AND:
- LDL-C ≥55 mg/dL (or non-HDL-C ≥85 mg/dL) → Consider adding nonstatin therapy 1
- LDL-C ≥70 mg/dL → Adding ezetimibe is reasonable (Class 2a recommendation) 1
If the patient has clinical ASCVD (not very high risk) AND:
- LDL-C ≥70 mg/dL → Consider adding ezetimibe 1
Step 3: Nonstatin Therapy Selection
First-line nonstatin agent:
- Ezetimibe provides an additional 15-25% LDL-C reduction when added to statin therapy 2
- Ezetimibe added to ongoing statin therapy significantly lowers total-C, LDL-C, Apo B, and non-HDL-C (mean LDL-C reduction of 25% beyond statin alone) 2
If LDL-C remains ≥70 mg/dL on maximally tolerated statin plus ezetimibe:
- PCSK9 monoclonal antibodies can be beneficial to further reduce MACE risk (Class 2a recommendation) 1
- PCSK9 inhibitors provide 50-60% additional LDL-C lowering 3
Alternative considerations:
- Bempedoic acid may be considered as an alternative or addition 1
- Inclisiran may be considered for patients with poor adherence to PCSK9 mAbs (twice-yearly dosing), but cardiovascular outcomes trials are pending 1
Step 4: Monitoring
- Assess lipid response 4-12 weeks after adding therapy, then every 3-12 months 1
- Continue monitoring adherence to lifestyle modifications and medications 1
Common Pitfalls to Avoid
Pitfall 1: Assuming LDL-C <100 mg/dL is "good enough"
- The 2004 ATP III update explicitly stated that <100 mg/dL was a minimal goal, not the level of maximal benefit 1
- For very high-risk patients, an optional LDL-C goal of <70 mg/dL (now <55 mg/dL) provides additional absolute risk reduction 1
Pitfall 2: Focusing solely on LDL-C percentage reduction
- Both percentage reduction (≥50%) AND absolute LDL-C thresholds matter 1
- A patient achieving 50% reduction but still with LDL-C of 80 mg/dL may benefit from further lowering if at very high risk
Pitfall 3: Delaying nonstatin therapy due to cost concerns
- The cardiovascular outcomes benefit of ezetimibe and PCSK9 inhibitors in very high-risk patients is established 1
- Generic ezetimibe is now widely available and cost-effective
Pitfall 4: Not considering apolipoprotein B (apoB) testing
- ApoB provides superior assessment of residual cardiovascular risk in statin-treated patients compared to LDL-C alone, particularly in those with elevated triglycerides or low HDL-C 4
- If apoB is elevated despite LDL-C near target, this indicates residual risk and should prompt discussion about add-on therapy 4
The Bottom Line
You are not "just chasing numbers" when you intensify therapy in a patient already on high-intensity statins with LDL-C near target. The evidence clearly demonstrates that:
- Lower is better, with no apparent threshold for benefit 1
- Very high-risk patients derive meaningful MACE reduction from achieving LDL-C <70 mg/dL (ideally <55 mg/dL) 1
- Ezetimibe added to statin therapy reduces cardiovascular events, not just LDL-C numbers 1
- The 2025 ACC/AHA performance measures explicitly recommend nonstatin therapy for very high-risk patients with LDL-C ≥70 mg/dL on maximally tolerated statins 1
The goal is reducing heart attacks, strokes, and cardiovascular death—outcomes that matter to patients—not arbitrary numerical targets.
