Lipoprotein(a): The “Hidden” Cholesterol More Black Families Need to Hear About

At Kidney Konnect, we talk a lot about blood pressure, diabetes, and kidney function—but there’s another number many people in our community have never heard of: lipoprotein(a), or Lp(a). It’s a type of “bad” cholesterol particle that can quietly raise the risk of heart attack and stroke, even when your regular LDL cholesterol looks okay.

What Is Lp(a)?

Lp(a) is like an LDL (“bad”) cholesterol particle wearing an extra “coat” made of a sticky protein called apolipoprotein(a). That extra layer makes it more likely to help form plaque and blood clots in arteries, which can block blood flow to the heart or brain.

Here’s what makes Lp(a) different:

• It’s mostly genetic—your level is largely set by your genes, not what you eat.

• It doesn’t usually change much over your lifetime.

• It doesn’t show up separately on the standard cholesterol panel you get at your annual visit.

You can feel fine, have “normal” LDL, and still have high Lp(a).

How Many People Have High Lp(a)?

Experts estimate that about 1 in 5 people around the world have high Lp(a) levels, but most have never been tested. Studies show that certain groups—including many people of African ancestry—are more likely to have elevated Lp(a), which may help explain why we see more early heart and stroke problems in Black communities.

For a community already facing higher rates of hypertension, diabetes, and kidney disease, adding high Lp(a) on top can create a dangerous mix for heart and blood vessel health.

Why Your “Normal” LDL May Not Tell the Whole Story

On lab reports, the cholesterol riding on Lp(a) particles is counted inside your LDL number. That means two people can both have an LDL of, say, 100 mg/dL, but one has low Lp(a) and the other has very high Lp(a)—and the second person may be at much higher risk for heart attack or stroke.

This is especially important if:

• You or a close family member had a heart attack, stroke, or blocked arteries at a young age (men under 55, women under 65).

• You’ve had heart events even though your LDL has been “good” on paper.

• You already live with diabetes, high blood pressure, or kidney disease.

In these cases, asking about an Lp(a) test can help uncover “hidden” risk.

How Do You Test for Lp(a)?

Lp(a) is measured with a specific blood test—separate from your standard cholesterol panel. Some labs report it in milligrams per deciliter (mg/dL), others in nanomoles per liter (nmol/L); the higher the number, the higher the risk.

Right now, many clinics still don’t order this test routinely. Leading heart groups suggest considering Lp(a) testing at least once in a lifetime for people at increased risk, especially those with strong family histories of early heart disease.

Questions you can take to your next visit:

• “Given my family history, should I have my Lp(a) checked?”

• “If my Lp(a) is high, how will that change how we manage my cholesterol and blood pressure?”

• 
  

Can You Lower Lp(a)?

Here’s the tough truth: lifestyle changes that help regular LDL—like eating healthier and being active—do not significantly lower Lp(a). Common cholesterol medicines like statins don’t reduce Lp(a) either; some studies suggest they may slightly increase it, even while lowering overall risk by improving LDL and stabilizing plaque.

But this does not mean there is nothing you can do:

• Keeping LDL as low as possible helps offset the extra risk from high Lp(a).

• Controlling blood pressure, blood sugar, and avoiding tobacco are critical for protecting both heart and kidneys.

• New medicines that directly target Lp(a) are in advanced clinical trials and have shown they can dramatically lower Lp(a) levels.

We want our community to be ready and informed as these new treatments become available.

Why Kidney Konnect Cares About Lp(a)

Heart and kidney health are deeply connected: most people with kidney failure die from cardiovascular disease, not just from the kidneys themselves. For Black patients who already carry a higher burden of blood pressure problems, diabetes, and unequal access to care, high Lp(a) can be an added, invisible risk factor.

At Kidney Konnect, we see Lp(a) as another tool to help our community get the full picture—not half of it. Our goals are to:

• Raise awareness that “normal” LDL doesn’t automatically mean low risk.

• Encourage Black families to talk about heart attacks, strokes, and sudden deaths in the family—and share that history with their doctors.

• Help patients feel confident asking about Lp(a) testing and how it fits into their overall heart and kidney plan.

If you’re living with kidney disease, diabetes, high blood pressure, or a strong family history of heart problems, and you want help preparing questions for your next appointment, Kidney Konnect is here to support you with easy-to-understand tools and community-centered education.
