## Takeaway

ApoB is a better indicator of heart disease risk than LDL-C because it directly measures the number of harmful particles, which is more accurate than measuring only the cholesterol within them.

## The question

What are the physiological mechanisms that make apolipoprotein B (apoB) a superior marker of cardiovascular risk compared to low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol?

## Hypothesis

The review posits that specific physiological mechanisms related to the nature, number, and cholesterol content of atherogenic apoB lipoprotein particles explain why apoB is a more accurate marker of cardiovascular risk.

## Methods

This is a narrative review that outlines the physiological mechanisms. It discusses the nature and relative numbers of different apoB particles, the mechanisms governing the number of very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) particles, and the mechanisms governing the cholesterol mass within these particles. It also briefly outlines major apoB dyslipoproteinemias.

## Results

The review explains that LDL particles are typically the primary determinants of cardiovascular risk. It details how concentrations of triglycerides and LDL-C can obscure this relationship. It further clarifies that the total number of apoB particles, except in cases of dysbetalipoproteinemia, determines cardiovascular risk. The review highlights that the discordance between the cholesterol mass within apoB particles (measured as LDL-C or non-HDL-C) and the actual number of apoB particles (measured as apoB) is responsible for apoB's superior predictive power.

## Conclusion

Apolipoprotein B (apoB) is a more accurate marker of cardiovascular risk than LDL-C or non-high-density lipoprotein cholesterol due to specific physiological mechanisms related to the number and cholesterol content of atherogenic apoB lipoprotein particles. This review provides a physiological framework for healthcare providers to understand this superiority.

## Limitations

This is a review article and does not present new experimental data or a meta-analysis of existing studies. It focuses on explicating known physiological mechanisms.
