From the Guidelines
Your lipid profile indicates a high risk of atherosclerotic cardiovascular disease (ASCVD), and I strongly recommend initiating high-intensity statin therapy to reduce this risk. Your ApoB level of 1.51 g/L is significantly elevated, corresponding to a high lifetime risk for ASCVD, as indicated by the 2019 American College of Cardiology/American Heart Association guideline on the management of blood cholesterol 1. This guideline suggests that an ApoB level above 130 mg/dL, particularly when accompanied by persistently elevated triglycerides, denotes a high lifetime risk for ASCVD and favors the initiation of statin therapy.
Given your LDL cholesterol level of 5.81 mmol/L and non-HDL cholesterol level of 6.11 mmol/L, starting a high-intensity statin such as atorvastatin 40-80 mg daily or rosuvastatin 20-40 mg daily is advisable to reduce these levels significantly. The goal of therapy should be to reduce LDL by at least 50% from baseline and achieve an LDL below 1.8 mmol/L, especially if you have high cardiovascular risk factors.
Key aspects of your treatment plan should include:
- High-intensity statin therapy
- Lifestyle modifications:
- Diet: Adopt a Mediterranean or DASH diet low in saturated fats
- Exercise: Engage in regular physical activity, aiming for 150 minutes of moderate-intensity exercise weekly
- Weight management: If necessary, aim for a healthy weight
- Smoking cessation: If applicable
- Limit alcohol consumption
Regular follow-up lipid testing is crucial to monitor the response to treatment, initially after 4-12 weeks of starting therapy and then periodically. If statins alone are insufficient after this period, considering the addition of ezetimibe 10 mg daily may be appropriate to further reduce your lipid levels and ASCVD risk. The presence of elevated ApoB, along with other lipid parameters, underscores the importance of aggressive management to mitigate your cardiovascular risk, as suggested by the guideline 1.

From the Research
Lipid Profile Analysis
- The provided lipid profile shows an ApoB level of 1.51 g/L, LDL cholesterol of 5.81 mmol/L, and non-HDL cholesterol of 6.11 mmol/L.
- According to the study 2, the apoB target of <90 mg/dl is roughly equivalent to an LDL-C level <100 mg/dl and a non-HDL-C level <130 mg/dl in untreated patients.
- However, during statin therapy, to reach an apoB target of <90 mg/dl, it is necessary to reduce non-HDL-C to <100 mg/dl or to reduce LDL-C to <70 mg/dl (in high-triglyceride patients) or <80 mg/dl (in lower-triglyceride patients) 2.
Cardiovascular Risk Assessment
- The 2019 European Society of Cardiology/European Atherosclerosis Society Guidelines concluded that apolipoprotein B (apoB) is a more accurate measure of cardiovascular risk and a better guide to the adequacy of lipid lowering than low-density lipoprotein cholesterol (LDL-C) or non-high-density lipoprotein cholesterol (HDL-C) 3.
- ApoB is considered a superior marker of cardiovascular risk compared to LDL-C and non-HDL-C, as it is a direct measure of the number of atherogenic particles 3, 4, 5.
- The study 5 found that apoB and non-HDL-C were better predictors of cardiovascular risk than LDL-C, and that apoB detected prevalent CVD, while non-HDL-C only detected prevalent CVD in men.
Lipid Lowering Therapy
- The study 6 suggests that targeting only LDL-C could result in missed opportunities for cardiovascular risk reduction in patients with type 2 diabetes, and that non-HDL-C, ApoB, and oxidized LDL-C levels could be considered as an important part of these patients' evaluation.
- The use of apoB and non-HDL-C as targets for lipid lowering therapy may provide a more accurate estimation of cardiovascular risk and better management of high-risk patients 2, 3, 6.
