High Lipoprotein(a) (Lp(a)): what it means

A Lipoprotein(a) (Lp(a)) result above the normal range is considered high. Here is what a raised Lipoprotein(a) (Lp(a)) can point to, and when it is worth discussing with a doctor.

Reference range: <75 nmol/L low risk; ≥125 nmol/L high CV risk (ESC 2019)

Understand your full result

What a high Lipoprotein(a) (Lp(a)) can mean

  • ≥125 nmol/L (≈≥50 mg/dL) — high cardiovascular risk; aggressive LDL lowering and risk-factor control advised.
  • ≥175 nmol/L — very high risk; consider lipoprotein apheresis or emerging PCSK9 / pelacarsen trials.
  • Family history of early heart attack or stroke sharply amplifies the meaning of any elevation.
  • Aortic stenosis at younger age — Lp(a) drives valve calcification.

When to discuss with a doctor

If your Lp(a) is in the high-risk band, the standard playbook is to lower LDL aggressively (statin + ezetimibe; consider PCSK9 inhibitor when warranted), tightly control blood pressure, stop smoking and discuss family screening with your physician. Mediora.AI surfaces Lp(a) alongside your LDL trajectory; treatment changes belong with a clinician.
