Lowering Non-HDL Cholesterol Levels: Guidelines, Chart, and Additional Information
In diagnosing high cholesterol, doctors utilise a blood test that measures various components, including LDL, HDL, triglycerides, and total cholesterol [1]. High cholesterol is managed through lifestyle adjustments and medication, with statins being the primary class of drugs used for treatment [1].
Recent reviews have highlighted the significance of non-HDL cholesterol, a measure representing all cholesterols other than HDL, as a consistent and reliable predictor of arteriosclerotic cardiovascular disease [1][2]. This finding underscores the importance of understanding non-HDL cholesterol and its role in cardiovascular health.
Non-HDL Cholesterol Targets
The recommended non-HDL cholesterol levels vary based on overall cardiovascular risk rather than strictly by age. Generally, non-HDL cholesterol targets are set about 30 mg/dL higher than corresponding LDL cholesterol targets because non-HDL cholesterol includes LDL plus other atherogenic particles [1][2].
| Risk Level | LDL Cholesterol Target (mg/dL) | Corresponding Non-HDL Cholesterol Target (mg/dL) | |-----------------------------------|--------------------------------|-------------------------------------------------| | Low to Moderate Risk (no major risk factors) | < 100-130 | < 130-160 | | Elevated Risk (e.g., diabetes, established CVD or multiple risk factors) | < 70-100 | < 100-130 | | Very High Risk (e.g., recurrent CVD events) | < 70 or even lower | < 100 or even < 80 |
For most adults without additional risk factors, a non-HDL cholesterol level below 130 mg/dL is considered optimal [1][2]. However, if diabetic, have established cardiovascular disease, or multiple risk factors (including age > 45 for men, >55 for women), the target may be lowered to under 100 mg/dL [1][2]. In very high-risk cases, targets below 80 mg/dL for non-HDL cholesterol might be recommended [1].
Comparison with LDL Cholesterol
Non-HDL cholesterol includes LDL, very-low-density lipoprotein (VLDL), and other atherogenic lipoproteins, providing a more comprehensive risk marker than LDL alone [1][2]. LDL cholesterol targets are typically 30 mg/dL lower than corresponding non-HDL targets because LDL is a subset of non-HDL cholesterol [1][2].
Age and Risk Factors
Age is an important risk factor contributing to target setting, with men over 45 and women over 55 generally considered higher risk, which can justify stricter cholesterol goals [1]. Other risk factors that influence target levels include smoking, hypertension, family history of CVD, diabetes, and overall cardiovascular disease presence [1][5]. Guidelines emphasize individualizing targets based on comprehensive risk profiling rather than age alone [1].
Summary of Recommended Values
- Non-HDL Cholesterol:
- Ideal for most adults: < 130 mg/dL
- Higher risk (diabetes, prior CVD): < 100 mg/dL
- Very high risk: < 80 mg/dL
- Borderline or elevated levels are categorized as 130-159 (near ideal), 160-189 (borderline high), 190-219 (high), and >220 (very high) [1][2]
- LDL Cholesterol:
- Optimal generally < 100 mg/dL for adults
- < 70 mg/dL for very high-risk individuals (e.g., those with CVD)
- Levels between 100-129 may be acceptable for low-risk younger adults but not recommended if other risk factors exist [5]
In conclusion, non-HDL cholesterol is increasingly recognized as a better predictor of cardiovascular risk. This is due to its inclusion of additional atherogenic lipoproteins, which results in non-HDL cholesterol targets being set systematically about 30 mg/dL higher than LDL cholesterol targets. Lower goals are recommended for increasing levels of risk, including age-related risk combined with other factors.
