Myths vs facts: ApoB and Langlebigkeit

ApoB (Apolipoprotein B) is a core component of atherogenic lipoproteins (LDL, VLDL, IDL, Lp(a)). A common myth is that only LDL cholesterol matters. In fact, ApoB is a more accurate marker of atherogenic particle number and correlates more strongly with cardiovascular events and mortality than LDL-C alone. Another myth: ApoB is not modifiable. Evidence shows lifestyle (healthy fats, fiber, exercise) and medications (statins, PCSK9 inhibitors) effectively lower ApoB. Fact: Elevated ApoB is an independent risk factor for atherosclerosis and reduces longevity. However, ApoB is not the sole determinant of longevity – inflammation, glycemic control, blood pressure, and genetics also contribute. Evidence is strong from large prospective cohorts and Mendelian randomization studies. Caveat: Most data come from Western populations; individual risk assessment should be done in a clinical context.
