High Lp(a): what to do next

Updated 2026-10-14Written for education by the Zenlo Health editorial teamHow we review
Quick answerA high Lp(a) raises lifetime risk but does not decide your future. Confirm the unit and level, tighten control of LDL, ApoB, blood pressure, and blood sugar, and talk with a clinician about a coronary calcium scan and testing relatives.

Step by step

  1. Check the unit. Lp(a) appears in mg/dL or nmol/L. Many guidelines treat 50 mg/dL (about 125 nmol/L) or higher as risk-enhancing.
  2. Get the full picture. Review LDL, ApoB, blood pressure, A1C, weight, and smoking status.
  3. Lower what you can change. LDL and ApoB respond to diet, exercise, and medicine. Your clinician decides on treatment.
  4. Ask about a coronary calcium scan. It shows whether plaque has already formed, which can shape how firm your plan is.
  5. Test close relatives. Lp(a) runs in families.
  6. Do not repeat it often. Levels stay fairly stable in adults. A repeat can make sense after major changes such as menopause or kidney disease.

What does not work

Diet and exercise lower other risks but move Lp(a) very little. Supplements that claim to lower Lp(a) lack strong proof. Talk with a clinician before you buy one.

When to see someone soon

A high Lp(a) plus a personal history of early heart disease, stroke, or a very high LDL merits a prompt visit with a cardiologist or lipid specialist.

When to get care right away. Chest pain or pressure, shortness of breath, fainting, or sudden weakness on one side: call 911.

Questions people ask

Does a high Lp(a) mean I will have a heart attack?

No. It raises lifetime risk. Many people with a high level never have an event, especially when they control other risks.

Should my family be tested?

Lp(a) is inherited, so close relatives can have a similar level. Ask a clinician about testing first-degree relatives.

Is there a drug that lowers Lp(a)?

No medicine is approved specifically to lower Lp(a) as of this writing. Several are in late-stage trials. Ask a clinician for the current status.
