Lipoprotein(a): What It Is, Values, and How to Reduce Your Cardiovascular Risk

Hello, I am Dr. Isabel Viña Bas, a physician and Scientific Director of IVB Wellness Lab. When we talk about cardiovascular health, almost everyone stops at two words: cholesterol and triglycerides. We focus on LDL, celebrate if HDL is good, and think that's the end of the story. But there is a particle that may have been circulating in your blood for years without anyone ever asking for it in a blood test: Lipoprotein(a), or Lp(a). And this is one of those cases where knowing more doesn't mean living with more fear, but rather making better decisions.

Lipoprotein(a) has a huge genetic component, affects approximately 1 in 5 people, and can raise your cardiovascular risk even when the rest of your lipid profile is fine. You don't choose the genes you are born with, but you can certainly get to know them.

What is Lipoprotein(a) and why isn't it just "another bad cholesterol"?

Lipoprotein(a) is a particle that transports lipids through the blood. At first glance, it looks like other cholesterol-related particles, but it has a plus: in addition to transporting fats, it behaves as an inflammatory and oxidizing agent in its own right.

With traditional cholesterol, we talk mostly about diet, exercise, body composition, or metabolism. With Lipoprotein(a), the weight of genetics is much greater: more than 90% of its levels are genetically determined.

And this avoids two very common mistakes. The first: thinking "if it came back high, it's because I'm doing something wrong." Not necessarily. The second, falling into the opposite extreme: "since it's genetic, I can't do anything." Also not true: you can work on everything surrounding it.

The marble and gum analogy: why Lipoprotein(a) sticks so easily

To explain its structure, I'm going to use a very simple mental image. Imagine a traditional cholesterol particle as a smooth marble circulating in the blood. Lipoprotein(a) is that same marble, but with a piece of "gum" stuck on top.

That gum is apolipoprotein(a). It makes the particle different and gives it a greater capacity to adhere and participate in inflammatory and oxidative processes on the vascular wall. Counterintuitively, the smaller that apolipoprotein(a) is, the greater the associated risk can be; larger forms usually carry less risk.

I like this metaphor because it makes one idea clear: we are not simply talking about "having more cholesterol." We are talking about a particle with its own characteristics that deserves to be evaluated specifically.

Why should you measure Lipoprotein(a) at least once in your life?

Precisely because it is so conditioned by genetics, you don't need to chase it in every blood test as we do with other markers that change with lifestyle. The 2022 consensus of the European Atherosclerosis Society recommends measuring Lipoprotein(a) at least once in your life for the general population.

The logic is simple. If the value comes back low, you now know one more piece of your cardiovascular risk puzzle, and since it depends so much on genetics, there is no need to repeat it continuously. If it comes back high, you have discovered a predisposition that allows you to act sooner.

Ideally, this information should be known from young adulthood. Not to medicalize a healthy person, but because a genetic exposure that acts over decades is much better prevented over time than it is discovered after a cardiovascular event.

What are the normal values for Lipoprotein(a) and when do they indicate risk?

One of the points that causes the most confusion is that laboratories express Lipoprotein(a) in different units. I work with two references:

• Low values: below 30 mg/dL or 75 nmol/L. In this range, Lp(a) does not add that genetic risk component we talked about.

• High values: above 50 mg/dL or 125 nmol/L. From here on, we are talking about a cardiovascular risk factor that must be integrated into your overall assessment.

And here is the keyword: overall. An isolated value does not decide whether you are going to have a heart attack. It serves to build a much more complete risk map.

What risks does high Lipoprotein(a) have for your heart?

Elevated Lipoprotein(a) functions as an independent risk factor: it can add risk even if the rest of your cholesterol is fine.

It is related to events such as myocardial infarction, stroke, and heart failure. It also has an interesting relationship with the aortic valve, because it promotes calcification that can end up narrowing it and causing aortic stenosis.

That is why I don't like to reduce all cardiovascular prevention to "having good or bad cholesterol." The heart does not get sick from a single figure: lipid particles, blood pressure, glucose and insulin, smoking, inflammation, the state of the arteries, and, in some people, a genetic predisposition like Lp(a) all come into play.

My Lipoprotein(a) came back high: what do I do now?

The first thing is not to panic or try to lower the number with randomly chosen food supplements. If Lipoprotein(a) is elevated, I recommend that the assessment continue with cardiology.

One of the tests that can be used is the echocardiogram, which allows you to see the heart valves and check if the aortic valve shows narrowing or calcification.

Another tool is the coronary Angio-CT and the assessment of arterial calcium using the calcium score. I use a guiding scale: a score of 0 is the ideal scenario; between 1 and 99 there is some calcification; above 100 the risk gains relevance, and above 300 we are talking about a very high calcium load.

These tests are not something you should order on your own because you read an article. They serve for a specialist to integrate your Lp(a) with your complete clinical situation.

Statins and Lipoprotein(a): the paradox that shouldn't make you abandon treatment

Here appears one of the doubts that scares people the most when they research on their own on the internet. There are reviews in thousands of patients where statins can raise Lipoprotein(a) between 10% and 20%.

Does that mean you should stop a statin if Lp(a) is high? No. And this is extremely important: never stop a statin on your own for that reason. The cardiovascular benefit it provides far outweighs that small increase in Lp(a).

If your cardiologist considers that the treatment should change, there are other pharmacological strategies for cholesterol (such as bempedoic acid, ezetimibe, or PCSK9 inhibitors) that are assessed individually. It is not about choosing a molecule by reading a list, but about treating the complete risk.

Today there is no approved drug whose specific indication is to lower Lipoprotein(a), although there are therapies in advanced stages of research. Some treatments used for other lipid alterations, such as PCSK9 inhibitors or lomitapide, can reduce it indirectly.

If genetics don't change, change the rest of the cards in the cardiovascular "bingo"

This is probably the most important idea in the entire article. Having high Lipoprotein(a) is not equivalent to having a written destiny. Cardiovascular disease is like a brownie: it doesn't appear because of a single ingredient.

If you already know you have that genetic predisposition, your goal is not to add avoidable risk factors. That means being demanding with smoking, alcohol, blood pressure, excess sugar, insulin resistance, body composition, and a sedentary lifestyle.

Strength training has a very interesting role here, because building muscle improves the metabolic environment and helps manage glucose and insulin better. You don't train to "lower Lp(a)" directly; you train to reduce the metabolic and inflammatory terrain.

Sugar, insulin, and arterial wall: why protecting the vessel matters as much as watching cholesterol

Another comparison I use a lot: when Coca-Cola falls on a surface, it remains sticky. A sustained excess of blood sugar damages the structural proteins of the vascular wall and worsens endothelial health.

If the arterial wall is deteriorated and, at the same time, a particle with great inflammatory and adhesive capacity is circulating, you are adding ingredients you don't want to combine. That is why controlling glucose and insulin is part of the same problem.

I also often talk about microplastics, whose presence within arteriosclerosis plaques has been linked to greater instability of those plaques. Modern cardiovascular risk is built by accumulation of exposures.

Fiber, microbiota, and antioxidants: how to support your cardiovascular terrain through nutrition

When genetics cannot be modified, nutrition ceases to be a tool to "correct the gene" and becomes a way to improve the scenario in which that gene is expressed.

Fiber is one of the pieces that interests me the most. Fibers like partially hydrolyzed guar gum, xylooligosaccharides, baobab, inulin, or fructooligosaccharides help the gut and can also support the metabolism of glucose and lipids.

That is why Fiber Total fits so well into this approach when the diet does not cover fiber needs. It combines Sunfiber® (partially hydrolyzed guar gum), PreticX® (xylooligosaccharides), and Inavea® (baobab and acacia gum), three types of fiber that work on the microbiota from different pathways.

Not just any probiotic works for any goal. For the lipid profile, I specifically use Lactobacillus reuteri LRC, originally known as NCIMB 30242, in an amount of 2.5 × 10⁹ CFU: specific strains studied for specific functions.

Berberine, silymarin, and antioxidants: how to reduce the risk you can modify

Another strategy I use is to work on glucose and lipid metabolism with tools like berberine and silymarin, especially when there is insulin resistance, dyslipidemia, or metabolic alterations that add cardiovascular risk.

With that logic, we formulated Metabolic-Max: it combines berberine in phytosome form Berbevis®, silymarin, Gymnema sylvestre, and chromium. It is not intended to "cure" a genetic Lipoprotein(a), but to act on modifiable metabolic factors.

The second front is oxidative stress. Coenzyme Q10, vitamins C and E, astaxanthin, lutein, quercetin, glycine, NAC, and lycopene are antioxidant support tools. Anti-OX Global brings together several of those compounds within a strategy aimed at cellular protection.

The idea is not to build a tower of food supplements. It is to identify which risk factors you actually have and prioritize. If your Lp(a) is high but the rest of your profile is controlled, the approach will be very different from that of someone who also smokes and has hypertension.

High Lipoprotein(a): a signal to better understand your risk, not to live in fear

Lipoprotein(a) summarizes very well how I understand preventive medicine. There are things we don't choose: genes, family history, certain predispositions. But knowing them allows us to stop playing blind.

Asking for it at least once, interpreting its values well, and, if it is elevated, assessing the real state of your cardiovascular system transforms a scary piece of data into useful information. Then comes the important part: protecting the arterial wall, controlling the rest of the cholesterol, not smoking, training muscle, and taking care of fiber.

You cannot peel the genetic "gum" off the marble, but you can certainly make the path it travels along much better protected.

Transforming your health is a matter of applying science with consistency, day by day. You have in your hands the necessary knowledge to better understand your cardiovascular risk and make decisions with criteria, without alarmism and without ignoring important signals.

I hope you like it :)
