Many people who suffer a heart attack never knew they were at elevated risk, not because the warning signs weren’t there, but because no one looked for them.
Heart disease remains the leading cause of death worldwide, yet many people are unaware of one of the most important risk factors for cardiovascular disease: Lipoprotein(a), commonly known as Lp(a). This cholesterol particle is similar to LDL (bad cholesterol), but with an additional protein, apolipoprotein(a), attached to it, which can contribute to both the buildup of plaque in arteries and the formation of blood clots.
Unlike many traditional risk factors, such as high cholesterol or high blood pressure, your Lp(a) level is largely determined by your genes, and it rarely causes symptoms. You can eat a healthy diet, exercise regularly, and maintain a healthy lifestyle, and still have an elevated Lp(a) level that increases your long-term risk of heart attack or stroke by 40%.
According to the American Heart Association (AHA), approximately 1 in 5 people have elevated Lp(a). This simple blood test is not included in a routine cholesterol panel, but today, the AHA and numerous other cardiovascular organizations recommend that every adult have Lp(a) measured at least once. Knowing your number is a simple step that can help guide more informed decisions about your long-term heart health.
At Radence, we don’t interpret biomarkers like Lp(a) in isolation. We evaluate them alongside genetics, advanced imaging, family history, metabolic health, and longitudinal clinical data to understand what they mean for you and, more importantly, what to do next. This allows you and your physician to develop a personalized prevention strategy to manage the modifiable cardiovascular risk factors you can control.
Why This Matters
Knowing your Lp(a) level doesn’t just tell you your cardiovascular risk. It changes how aggressively we manage the factors we can control, from cholesterol management to preventive strategies.
Who Should be Tested for Lp(a)?
Because Lp(a) is inherited, anyone can have an elevated level. Testing is particularly important if you:
- Have a personal or family history of premature heart disease or stroke
- Have high cholesterol or cardiovascular disease that cannot be fully explained by traditional risk factors
- Have a close biological relative with elevated Lp(a)
- Want a more complete understanding of your long-term cardiovascular risk
Certain populations, including people of African, African American, and South Asian ancestry, are also more likely to have elevated Lp(a). In addition, Lp(a) levels may increase during certain life stages, including pregnancy and menopause. Certain medical conditions, such as kidney disease, liver disease, and thyroid disorders, may also influence Lp(a) levels or contribute to an individual’s overall cardiovascular risk.
If your Lp(a) is elevated, your physician may recommend testing your close biological relatives, including parents, siblings, and children, to determine whether they also carry elevated levels.
Understanding Your Results
An elevated Lp(a) level increases cardiovascular risk, but it should always be interpreted alongside your other risk factors, including LDL cholesterol, blood pressure, diabetes, smoking history, and family history.
While there is no universally accepted “safe” level, most experts consider 125 nmol/L (50 mg/dL) or higher to represent elevated cardiovascular risk. Risk continues to increase incrementally as Lp(a) rises and should always be interpreted in the context of your other cardiovascular risk factors.
What Can You Do If Your Lp(a) Is Elevated?
Although lifestyle changes generally do not lower Lp(a) itself, they can dramatically reduce your overall cardiovascular risk. Focusing on the risk factors within your control makes a meaningful difference.
Steps you can take today:
- Do not smoke or vape
- Follow a heart-healthy diet, such as the Mediterranean diet
- Exercise regularly (at least 150 minutes of moderate activity per week)
- Maintain a healthy weight
- Keep blood pressure under control
- Manage diabetes if present
- Lower LDL cholesterol as recommended by your physician
- Take prescribed medications consistently
- Stay engaged with regular preventive care and cardiovascular screening
While there is currently no FDA-approved medication specifically designed to lower Lp(a), several promising therapies are in late-stage clinical trials. The cardiovascular medicine community is watching these results closely. In the meantime, optimizing every other risk factor remains the best and most evidence-backed strategy for protecting your heart, including more aggressive and personalized approaches to cholesterol management and lifestyle interventions.
Prevention Starts with Knowing Your Risk
Most cardiovascular disease begins years earlier than when you feel it. We believe that prevention begins with understanding your unique biology. Measuring Lp(a) is just one example of how precision medicine can uncover hidden risks before they become life-changing events.
Knowing your number is about creating clarity and giving you the information you need to take proactive, targeted steps toward a longer, healthier life. Most people who experience a heart attack had no idea their Lp(a) was elevated. That is the kind of blind spot we are trying to close.
At Radence, precision medicine isn’t about ordering more tests. It’s about understanding which tests change decisions. Learn more about how we approach prevention to help you stay ahead of your health.
