High Lp(a): what should you actually do?

High Lp(a): what should you actually do? 🫀

Lipoprotein(a), or Lp(a), is largely genetically determined and is only minimally affected by diet, exercise, or weight loss. So when Lp(a) is elevated, the goal is not to “chase the number,” but to reduce overall cardiovascular risk.

📌 1. Assess the overall risk. An Lp(a) >50 mg/dL is considered an important risk modifier. It should be interpreted together with age, blood pressure, smoking, diabetes, LDL-C, family history, and any existing cardiovascular disease.

📌 2. Get LDL-C to target. This is currently the most important strategy. Statins, ezetimibe, bempedoic acid and/or PCSK9 inhibitors should be selected according to the patient’s individual cardiovascular risk. Statins do not lower Lp(a) and may sometimes increase it slightly, but this is NOT a reason to stop them: their cardiovascular benefit remains clear.

📌 3. Address modifiable risk factors. Blood pressure, blood glucose, body weight, smoking, physical inactivity, and diet matter even more when Lp(a) is elevated. Lifestyle changes have little effect on Lp(a) itself, but they can significantly reduce overall cardiovascular risk.

📌 4. Think about the family. If Lp(a) is elevated, testing first-degree relatives should be considered, as Lp(a) levels are strongly genetically determined.

📌 5. Avoid unproven treatments. At present, there is still no approved therapy specifically targeting Lp(a) with proven benefit on cardiovascular outcomes. Several targeted therapies are in advanced clinical development. In selected patients, lipoprotein apheresis may be considered in specialist centers.

👉 Key message: High Lp(a) does not mean that nothing can be done. It means recognizing an additional cardiovascular risk factor and treating everything we can modify more aggressively.
