From the Guidelines
For a patient with an LDL of 4.0 mmol/L, starting atorvastatin at 10 mg daily is a reasonable initial approach, as it is typically sufficient for patients requiring a 30-50% LDL reduction, and can be adjusted based on response and tolerability, as recommended by the expert panel on integrated guidelines for cardiovascular health and risk reduction in children and adolescents 1. When considering the treatment for high LDL, it is essential to evaluate the patient's overall cardiovascular risk profile, comorbidities, age, and potential for drug interactions.
- The choice of atorvastatin dose, either 10 mg or 20 mg, depends on the patient's individual needs and risk factors, with the goal of achieving a target LDL cholesterol level of less than 130 mg/dL, as recommended by the NCEP Adult Treatment Panel III guidelines 1.
- Atorvastatin should be taken at the same time each day, preferably in the evening, and patients should be counseled about potential side effects, including muscle pain, and the importance of reporting any symptoms suggestive of myopathy, as advised by the expert panel on integrated guidelines for cardiovascular health and risk reduction in children and adolescents 1.
- Lifestyle modifications, including diet changes, regular exercise, and smoking cessation, should accompany statin therapy to optimize the treatment of high LDL and reduce cardiovascular risk, as recommended by the 2012 ACCF/AHA focused update incorporated into the ACCF/AHA 2007 guidelines for the management of patients with unstable angina/non-ST-elevation myocardial infarction 1.
- The patient's response to therapy should be monitored by checking lipid levels and liver function tests in 4-12 weeks, and the dose of atorvastatin can be adjusted as needed to achieve the target LDL cholesterol level, as recommended by the expert panel on integrated guidelines for cardiovascular health and risk reduction in children and adolescents 1.

TABLE 8: Response to Ezetimibe Tablet and Atorvastatin Initiated Concurrently in Patients with Primary Hyperlipidemia (Mean % Change from Untreated Baseline*) Treatment (Daily Dose) N Total-C LDL-C Apo B Non-HDL-C Placebo 60 +4 +4 +3 +4 Ezetimibe Tablet 65 -14 -20 -15 -18 Atorvastatin 10 mg 60 -26 -37 -28 -34 Ezetimibe Tablet + Atorvastatin 10 mg 65 -38 -53 -43 -49 Atorvastatin 20 mg 60 -30 -42 -34 -39 Ezetimibe Tablet + Atorvastatin 20 mg 62 -39 -54 -44 -50
The patient has high LDL of 4.0. Atorvastatin 10 mg can lower LDL-C by 37% and Atorvastatin 20 mg can lower LDL-C by 42%.
- Atorvastatin 10 mg may be sufficient to treat the patient's high LDL.
- Atorvastatin 20 mg may be considered if a more significant reduction in LDL-C is needed. 2
From the Research
Treatment for High LDL
The treatment for high LDL (low-density lipoprotein) cholesterol levels typically involves lipid-lowering therapies, including statins.
- The primary treatment target in cardiovascular prevention is LDL-C, and potential alternative targets are apoB and non-HDL-C 3.
- Statin therapy reduces low-density lipoprotein (LDL) cholesterol levels and the risk of cardiovascular events 4.
Atorvastatin Dosage
For a patient with an LDL level of 4.0, atorvastatin 10 or 20 mg may be considered as a treatment option.
- However, the optimal target of LDL cholesterol level for statin treatment is still a topic of debate, with some studies suggesting that there is an optimal LDL-C level, i.e., a "threshold" value, below which the incidence of cardiovascular events is no longer reduced 5.
- The REALITY study found that most patients did not achieve their target LDL-C goals despite receiving high- or very high-intensity LLT, highlighting the need for more aggressive treatment strategies 6.
Considerations for Treatment
When considering treatment for high LDL, several factors should be taken into account, including:
