The next time you get bloodwork, ask for a lipoprotein(a) test. You likely need it only once in your life.
Lipoprotein(a), written Lp(a), is a cholesterol particle set almost entirely by your genes. Your level at forty tracks closely with your level at seventy, which is why a single test settles it.
It is rarely ordered. A standard lipid panel reports LDL, HDL, and triglycerides and skips Lp(a) entirely.
That gap matters, because Lp(a) is an independent, causal risk factor for atherosclerotic cardiovascular disease and for narrowing of the aortic valve, and it acts separately from the LDL number your doctor already watches.
In 2022 the European Atherosclerosis Society issued a consensus statement recommending that every adult have Lp(a) measured at least once. Roughly one in five people carry a level high enough to raise cardiovascular risk and have no idea it is there.
This is sharper for you than for a general adult. Estrogen appears to suppress Lp(a), and levels tend to rise across the menopausal transition, so a number you checked in your forties may understate where you sit now.
Ask for the result in nmol/L, the more precise unit. Below roughly 75 nmol/L is generally treated as low risk, and above about 125 nmol/L, or 50 mg/dL, flags elevated risk, though the exact thresholds are still debated across guidelines.
There is no approved drug that lowers Lp(a) on its own yet, with several in late-stage trials. What an elevated result does today is raise the urgency on the levers that already work, meaning blood pressure, LDL, ApoB, and not smoking.
Lp(a) is one blood draw that tells you something about your heart you cannot learn any other way, and it will not move. Get the number once, write it down, and bring it to every cardiovascular conversation you have for the rest of your life.
