From the Guidelines
For a 14-year-old female with an LDL >350 mg/dL, total cholesterol of 429 mg/dL, and HDL of 44 mg/dL, I strongly recommend immediate pharmacological intervention with a statin, in addition to therapeutic lifestyle changes, to reduce the risk of premature cardiovascular disease. The patient's LDL level is significantly elevated, suggesting familial hypercholesterolemia (FH), a genetic disorder that requires aggressive management to prevent cardiovascular complications 1.
Key Recommendations:
- Initiate statin therapy, such as atorvastatin (10-20 mg daily) or rosuvastatin (5-10 mg daily), to achieve tier 1 treatment goals for LDL cholesterol 1.
- Implement therapeutic lifestyle changes, including a heart-healthy diet low in saturated fats, regular physical activity, and maintaining a healthy weight 1.
- Consider adding ezetimibe (10 mg daily) if LDL goals are not achieved with statins alone.
- Regular monitoring of lipid levels and liver function tests is necessary every 3-6 months.
- Family screening is essential to identify other family members who may be affected by FH, as it is an autosomal dominant condition 1. The American Heart Association guidelines recommend considering pharmacological therapy for individuals with LDL ≥ 190 mg/dL with no other risk factors for CVD, or ≥ 160 mg/dL with other risk factors present 1.
Additional Considerations:
- Emphasize weight management and increased physical activity to reduce the risk of cardiovascular disease 1.
- Promote achievement of appropriate weight and reduce sodium in the diet 1.
- Consider evaluating for secondary causes of hyperlipidemia, such as thyroid-stimulating hormone, liver function tests, renal function tests, and urinalysis 1.

From the Research
Treatment Options for High LDL Cholesterol
The patient has an LDL cholesterol level of >350 and a total cholesterol level of 429, with an HDL level of 44. Based on the available evidence, the following treatment options can be considered:
- Statins are the most potent drugs for lowering LDL-C levels and are well tolerated in most patients 2.
- The addition of a bile acid sequestrant or ezetimibe to a statin can produce additional LDL-C reduction, allowing many patients to reach LDL-C targets 2, 3.
- Combination therapy with a statin and another lipid-modifying agent, such as ezetimibe, may be an alternative for patients who do not tolerate or respond to high-intensity statin monotherapy 3, 4.
- Ezetimibe remains a very important combination partner for statins, with continuously increasing treatment numbers 5.
Specific Treatment Considerations
- The patient's high LDL cholesterol level and total cholesterol level suggest the need for aggressive lipid-lowering therapy.
- The use of statins, either alone or in combination with other lipid-modifying agents, may be effective in reducing the patient's LDL cholesterol level and cardiovascular risk.
- The choice of treatment should be individualized based on the patient's specific needs and medical history, as well as the potential benefits and risks of each treatment option 6, 4.
Potential Treatment Regimens
- Statin monotherapy: a high-intensity statin may be prescribed to lower the patient's LDL cholesterol level.
- Combination therapy: a statin may be combined with ezetimibe or a bile acid sequestrant to achieve additional LDL-C reduction.
- Other treatment options: other lipid-modifying agents, such as fibrates or PCSK9 inhibitors, may be considered in certain cases, although their use may be limited by potential side effects or lack of evidence 5.
