Cholesterol: understanding cardiovascular risk beyond LDL

For years, when we talked about cholesterol, the conversation seemed to come down to one number: LDL.

But cardiovascular risk is far more complex than a single result on a blood test. Two people can have similar LDL levels and yet present very different risk profiles.

Today, we have markers that allow us to look more precisely at what is happening. ApoB, lipoprotein(a), HDL and triglycerides can all provide valuable information for building a more complete picture.

At SHOMMA, we do not interpret a number in isolation. We seek to understand the story told by the data as a whole.

1. Why normal total cholesterol can hide part of the story

Total cholesterol is useful, but it has an important limitation: it condenses too much information into a single number.

To understand the lipid profile more fully, we need to look at how the different lipoproteins are distributed, especially those involved in transporting cholesterol to tissues.

That is why an apparently “normal” result may prompt several questions:

• What is the LDL level?\n- What is the triglyceride level?\n- What is the HDL level?\n- How many atherogenic particles are circulating?\n- Is lipoprotein(a) elevated?\n- Are there other factors that modify cardiovascular risk?

The answer is not necessarily found in one number.

It lies in the relationship between the results and in each woman’s individual context.

2. LDL, HDL and triglycerides: the panel tells a story

LDL: an important piece, but not the only one

LDL is often known as “bad cholesterol.” This label is simple, but it can also be overly simplistic.

ApoB-containing particles, including LDL particles, transport cholesterol and can contribute to the development of atherosclerosis when present in excess over time.

Knowing LDL is therefore essential, but it is not always enough to fully characterise risk.

HDL: it is not always a case of “the higher, the better”

HDL is often called “good cholesterol.” However, interpreting HDL solely by its quantity can lead to overly simple conclusions.

High HDL does not automatically mean that cardiovascular risk is low, and low HDL should not be analysed in isolation either.

The key is to integrate this result with the rest of the metabolic and cardiovascular profile.

Triglycerides: a relevant metabolic signal

Triglycerides are also part of the picture.

They can reflect different aspects of energy metabolism and, when elevated, may be associated with metabolic changes such as insulin resistance, excess visceral fat or certain dietary and lifestyle patterns.

Looking at LDL + HDL + triglycerides therefore offers much more information than total cholesterol alone.

3. Two markers that can change the perspective: ApoB and Lp(a)

Two particularly interesting markers now come into view.

ApoB: how many atherogenic particles are there?

Apolipoprotein B (ApoB) is found in the main atherogenic lipoproteins.

While LDL-C tells us how much cholesterol is being carried within LDL particles, ApoB can provide information about the number of ApoB-containing particles.

This can be especially useful when particle number and the amount of cholesterol they carry do not tell exactly the same story.

Put simply:

LDL-C tells us how much cholesterol certain particles carry.\nApoB helps us estimate how many atherogenic particles are circulating.

That distinction can be clinically relevant for some people.

Lp(a): a risk that can go unnoticed

Lipoprotein(a), or Lp(a), is another marker that deserves attention.

One of its particular features is that levels are largely determined by genetics and tend to remain relatively stable throughout life.

A person can therefore have an apparently reassuring profile while still having elevated Lp(a), which may alter their overall cardiovascular risk assessment.

Because of its hereditary component, measuring it at least once in adulthood may be particularly useful, depending on clinical context and current recommendations.

4. How do we interpret the lipid profile at SHOMMA?

At SHOMMA, we begin with a simple idea:

A blood test is not a diagnosis; it is information.

And information becomes valuable when it is connected.

The lipid profile should therefore not be interpreted separately from the rest of a woman’s story.

Age, family history, blood pressure, body composition, physical activity, diet, smoking, glucose metabolism, sleep, hormonal stage and other factors can all change the interpretation of cardiovascular risk.

Context changes during certain stages of life.

The female hormonal transition, for example, may be accompanied by changes in body composition and different metabolic parameters. This does not mean that every change is a direct consequence of hormones, but rather that life stage forms part of the information we need to consider.

From an isolated result to a cardiovascular map

Imagine two women with similar total cholesterol.

For one, the rest of the profile may be reassuring.

For the other, we may find a different combination: elevated LDL, high triglycerides, elevated ApoB or elevated Lp(a), together with other risk factors.

The total cholesterol number may be similar. The story is not.

This is precisely the difference between looking at a blood test and understanding it.

At SHOMMA, we do not chase numbers

The purpose of a preventive cardiovascular assessment should not be to achieve a “perfect” blood test at any cost.

It should be to understand risk, identify which factors can be modified and make proportionate, sustainable decisions.

Sometimes this will involve nutrition, physical activity, body composition, sleep or stress.

At other times, it may mean considering family history, repeating certain measurements or exploring further studies.

When cardiovascular risk is significant, treatment decisions should be made individually with a healthcare professional.

Prevention does not mean worrying about every number.

It means having better data to make better decisions.

At SHOMMA

We do not look only at your cholesterol. We look at the context in which that cholesterol exists.

Because your data tells part of the story.

Context allows us to understand it.
