我测过

我的LDL高，做了Lp(a) and ApoB, 这两个都正常，所以对高一点的LD L就不是太担心了。
The Lp(a) (lipoprotein(a)) and ApoB (apolipoprotein B) blood tests measure specific lipoproteins that help assess cardiovascular risk beyond traditional cholesterol tests. Here’s an explanation of each:

 

Lp(a) Test

    •    What It Measures: Lipoprotein(a), a type of LDL (“bad” cholesterol) with an additional protein called apolipoprotein(a).

    •    Why It’s Important: Elevated Lp(a) levels are associated with an increased risk of atherosclerosis, heart attack, and stroke, regardless of other cholesterol levels.

    •    Genetic Component: Lp(a) levels are primarily determined by genetics, so lifestyle changes or medications may have limited impact on reducing it.

    •    Who Should Test: People with a family history of early cardiovascular disease, unexplained high cholesterol, or personal history of heart disease.

 

ApoB Test

    •    What It Measures: Apolipoprotein B, the main protein in atherogenic lipoproteins like LDL and VLDL (very low-density lipoprotein).

    •    Why It’s Important: ApoB reflects the total number of atherogenic particles in the blood, which may be a better indicator of cardiovascular risk than LDL-C alone.

    •    Significance: High ApoB levels mean more particles that can penetrate artery walls and cause plaque buildup, increasing cardiovascular disease risk.

    •    Who Should Test: Individuals with high LDL, diabetes, obesity, or a strong family history of heart disease.

 

Comparison and Use in Risk Assessment

    •    Both tests provide a more comprehensive view of cardiovascular risk when combined with traditional lipid panels.

    •    Lp(a) helps identify genetic risk, while ApoB measures the total burden of cholesterol-carrying particles.
