Lipoprotein(a), or Lp(a), is a cholesterol-like particle that 20% of people have in high levels, mostly due to inherited genes. According to Gram Research analysis, high Lp(a) significantly increases your risk of early heart attack, stroke, and heart valve disease—independent of other risk factors. While specific Lp(a)-lowering drugs aren’t yet available, you can reduce your heart disease risk through diet, exercise, cholesterol medications, and possibly aspirin, with new targeted treatments expected by late 2026.
Lipoprotein(a), or Lp(a), is a cholesterol-like particle in your blood that increases heart disease risk for about 1 in 5 people—mostly due to genetics you inherit from your parents. According to Gram Research analysis, this hidden risk factor is often missed by doctors even though it’s a major cause of early heart attacks and valve problems. The good news: doctors now know how to test for it and manage it with diet, exercise, and cholesterol medications. Even better news is coming—new drugs specifically designed to lower Lp(a) are being tested and could be available soon.
Key Statistics
A 2026 review in the Australian Journal of General Practice found that approximately 20% of individuals have elevated lipoprotein(a) levels, which are mostly genetically determined and represent a major independent risk factor for early heart disease.
According to the 2026 review, lipoprotein(a) is a significant but under-recognized cause of atherosclerotic cardiovascular disease and aortic valve stenosis, particularly in people with early-onset or familial heart disease.
A 2026 analysis of international medical guidelines recommends testing for lipoprotein(a) in people with early heart attacks or strokes, family history of early heart disease, and aortic valve stenosis, with some guidelines advocating universal testing in all adults.
The 2026 review notes that new lipoprotein(a)-lowering therapies are in clinical trials, with the first results expected to report in late 2026, offering potential new treatment options beyond current diet, exercise, and cholesterol medications.
The Quick Take
- What they studied: Whether doctors should test people for lipoprotein(a) levels and how to treat it if it’s high
- Who participated: This was a review of existing research and medical guidelines, not a study with human participants
- Key finding: About 20% of people have high Lp(a) levels that significantly increase their heart disease risk, but most don’t know they have it because it’s rarely tested
- What it means for you: If you have a family history of early heart disease or have had a heart attack or stroke before age 55, ask your doctor to test your Lp(a) level. Even if it’s high, you can reduce your risk through diet, exercise, and cholesterol medications
The Research Details
This research is a review article, meaning doctors examined all the best available evidence about lipoprotein(a) from around the world. They looked at scientific studies, medical guidelines from major health organizations, and current treatment options to create a complete picture of what we know and don’t know about this risk factor.
The researchers focused on three main questions: Who should be tested for high Lp(a)? What does high Lp(a) mean for your health? And what can doctors do to help people with high levels? They reviewed recommendations from international heart disease experts and looked at which new treatments are being developed.
This type of review is valuable because it brings together information from many different studies and expert opinions, giving doctors and patients a clear summary of the current state of knowledge about a health topic.
A review article like this is important because lipoprotein(a) is a serious but under-recognized risk factor. Many doctors don’t routinely test for it, and many patients don’t know it exists. By summarizing all the evidence in one place, this research helps doctors understand when to test for Lp(a) and how to manage it. It also highlights that while we don’t yet have specific drugs to lower Lp(a), we do have proven ways to reduce heart disease risk in people who have high levels.
This review was published in a respected Australian medical journal and represents current international medical thinking. The authors examined established guidelines from major health organizations, which adds credibility. However, because this is a review rather than a new research study, it summarizes what others have found rather than presenting brand-new data. The reliability depends on the quality of the studies and guidelines reviewed.
What the Results Show
About 20% of people have elevated lipoprotein(a) levels, and for most of these people, their high levels are determined by genes they inherited from their parents. This means you can’t prevent high Lp(a) through diet or exercise alone—it’s largely written into your DNA.
Lipoprotein(a) is a major independent risk factor for atherosclerotic cardiovascular disease, which means it increases your heart disease risk on its own, separate from other risk factors like high cholesterol or high blood pressure. People with high Lp(a) are at increased risk for early heart attacks, strokes, and aortic valve stenosis (a narrowing of the heart valve).
The research shows that doctors should test for Lp(a) in specific high-risk groups: people who have already had a heart attack or stroke (especially at a young age), people with a family history of early heart disease, and people with aortic valve problems. Some international guidelines even recommend testing all adults as part of routine heart disease risk assessment.
While specific Lp(a)-lowering medications don’t yet exist, people with high levels can reduce their heart disease risk through proven strategies: eating a heart-healthy diet, exercising regularly, maintaining a healthy weight, not smoking, and taking cholesterol-lowering medications like statins. Aspirin may also help prevent heart disease in some people with high Lp(a).
The research highlights that Lp(a) is often overlooked in medical practice, even though it’s a major risk factor. This means many people with dangerously high levels don’t know it and aren’t getting appropriate treatment. The review also notes that new medications specifically designed to lower Lp(a) are currently in clinical trials, with the first results expected in late 2026. These new drugs work by preventing the body from making Lp(a) in the first place, which is different from current cholesterol medications.
This review reflects growing recognition in the medical community that Lp(a) deserves more attention. In the past, doctors focused mainly on LDL cholesterol (the ‘bad’ cholesterol) and didn’t routinely measure Lp(a). Recent research has shown that Lp(a) is just as important—or sometimes more important—than LDL cholesterol for predicting heart disease risk. This review brings together that evolving evidence and shows how medical thinking about Lp(a) has changed.
This is a review of existing research rather than a new study, so it doesn’t provide brand-new data. The review doesn’t include results from the new Lp(a)-lowering drugs because they haven’t finished testing yet. Additionally, while the review identifies who should be tested for Lp(a), it doesn’t provide detailed guidance on exactly how to manage every person with high levels, since treatment approaches are still evolving. The review also notes that more research is needed to understand the best ways to prevent heart disease in people with high Lp(a).
The Bottom Line
If you have a family history of early heart disease, have had a heart attack or stroke before age 55, or have aortic valve problems, ask your doctor to test your Lp(a) level. This is a strong recommendation based on solid evidence. If your Lp(a) is high, focus on proven risk-reducing strategies: eat a heart-healthy diet (low in saturated fat and high in vegetables), exercise regularly, maintain a healthy weight, don’t smoke, and take cholesterol medications if your doctor recommends them. Some doctors may also recommend aspirin for primary prevention. These recommendations have high confidence because they’re based on established medical evidence.
Anyone with a family history of early heart disease should care about Lp(a). People who have already had a heart attack or stroke should definitely know their Lp(a) level. People with aortic valve disease should also be tested. Even people without these risk factors might benefit from knowing their Lp(a) level, since some medical organizations recommend testing all adults. However, if you have no family history of early heart disease and have never had heart problems, the urgency is lower—but it’s still worth discussing with your doctor.
If you have high Lp(a) and start making lifestyle changes like improving your diet and exercising, you may see improvements in your overall heart health within weeks to months. However, because Lp(a) is genetically determined, you won’t be able to lower it through lifestyle changes alone. The new Lp(a)-lowering medications being tested may become available within the next 1-2 years, which could provide additional benefits for people with very high levels.
Frequently Asked Questions
What is lipoprotein(a) and why is it dangerous?
Lipoprotein(a) is a cholesterol-like particle in your blood that increases heart disease risk. About 20% of people have high levels due to inherited genes. It’s dangerous because it independently raises your risk of early heart attacks, strokes, and heart valve problems, even if your other cholesterol levels are normal.
Should I get tested for lipoprotein(a)?
Yes, if you have a family history of early heart disease, have had a heart attack or stroke before age 55, or have aortic valve disease. Ask your doctor about testing. Some medical organizations recommend all adults get tested as part of routine heart disease screening.
Can I lower my lipoprotein(a) with diet and exercise?
Diet and exercise alone won’t significantly lower Lp(a) because it’s mostly genetically determined. However, they reduce your overall heart disease risk. Cholesterol medications may help, and new drugs specifically targeting Lp(a) are in clinical trials with results expected by late 2026.
What should I do if my lipoprotein(a) is high?
Focus on proven heart disease prevention: eat a heart-healthy diet low in saturated fat, exercise 150 minutes weekly, maintain a healthy weight, don’t smoke, and take cholesterol medications if prescribed. Talk to your doctor about aspirin for prevention and ask about new Lp(a)-lowering treatments becoming available.
When will new lipoprotein(a) treatments be available?
New medications designed to lower Lp(a) are currently in clinical trials. The first results are expected to report in late 2026. These drugs work by preventing your body from making Lp(a), offering a new approach beyond current cholesterol medications.
