ApoB is a validated clinical measurement that augments the information found in a standard lipoprotein lipid panel; therefore, there is clinical value in using apoB in conjunction with a standard lipoprotein lipid profile when assessing risk and managing lipid-lowering therapy (LLT). ApoB has been shown to be superior to LDL-C in risk assessment both before and during treatment with LLT. In individuals, there can be discordance between levels of LDL-C and apoB, as well as LDL-C and non-high-density lipoprotein cholesterol (non-HDL-C), despite high levels of population-wide correlation. When there is discordance between LDL-C and apoB, or LDL-C and non-HDL-C, atherosclerotic cardiovascular disease risk generally aligns better with apoB or non-HDL-C. Additionally, apoB can be used in tandem with standard lipoprotein lipid measurements to diagnose distinct lipoprotein phenotypes. ApoB testing can inform clinical prognosis and care, as well as enable family cascade screening, when an inherited lipoprotein syndrome is identified. The NLA and other organizations will continue to educate clinicians about the role of apoB measurement in improving clinical risk assessment and dyslipidemia management.

To date, the only approved treatment to lower Lp(a) is lipoprotein apheresis (LA). Previous studies have demonstrated that LA is effective in reducing cardiovascular (CV) risk in patients with elevated low-density lipoprotein cholesterol (LDL-C) and/or Lp(a). Here we report our long-term experience with LA and its effectiveness in reducing CVD events in patients with elevated Lp(a).</div></div><div><h3>METHODS</h3><div>This retrospective open-label, single-center study included 25 individuals with Lp(a) elevation &gt;60 mg/dL and LDL-C &lt; 2.59 mmol/L who had indication for LA. The primary endpoint of this study was the incidence of any CV event (determined by medical records) after initiation of LA.</div></div><div><h3>RESULTS</h3><div>Mean LA treatment duration was 7.1 years (min-max: 1–19 years). Median Lp(a) was reduced from 95.0 to 31.1 mg/dL after LA (-67.3%, <em>p</em> &lt; 0.0001). Mean LDL-C was reduced from 1.85 to 0.76 mmol/L after LA (-58.9%, <em>p</em> &lt; 0.0001). Prior to LA, 81 CV events occurred in total (0.87 events/patient/year). During LA, 49 CV events occurred in total (0.24 events/patient/year; -0.63, <em>p</em> = 0.001). Yearly major adverse cardiac event (MACE) rate was reduced from 0.34 to 0.006 (-0.33, <em>p</em> = 0.0002). Similar results were obtained when considering only individuals with baseline LDL-C below 1.42 mmol/L.</div></div><div><h3>CONCLUSION</h3><div>In this observational study of a heterogeneous CV high-risk cohort with elevated Lp(a), LA reduced Lp(a) levels and was paralleled by a decrease in CV events and MACE.
