Dr Ula: Your car gets a service. Your heart gets a WOF.

Why the check that confirms nothing has failed is not the same as the one that finds what’s wearing out too quickly.

When someone your own age has a heart attack — a colleague, someone you trained with, a friend you’d have called fit — the news lands differently than a headline about a stranger. It doesn’t frighten you so much as change the question. Not “could that happen?”, but “where do I actually stand?” And most of us answer that question with whatever our last check-up told us. For most people, that check-up is the medical equivalent of a Warrant of Fitness.

A WOF is a good thing. It confirms the car is safe to drive today against a defined list of checks. But no careful owner runs a car they intend to keep on WOFs alone. They service it, because a WOF tells you nothing has failed yet, while a service looks at what’s quietly wearing out before it does fail. We accept that logic without question for a vehicle we’ll replace in a decade. We rarely apply it to a body that must last eighty years.

What the standard check sees, and what it doesn’t

Take the number most people think of as their heart-risk check: cholesterol. A standard panel reports total cholesterol and an LDL-cholesterol figure, and that LDL-c figure is usually not measured directly. It’s calculated from an equation. It’s a reasonable estimate, and like a WOF it does its job: it flags the obvious. What it doesn’t do is count the particles that actually drive arterial disease.

That count has a name: ApoB. Every atherogenic particle — the kind that lodges in an artery wall and builds plaque — carries exactly one ApoB marker, so measuring ApoB tells you how many of those particles are actually in circulation. The catch is that this number can sit high even when a standard cholesterol result reads reassuringly. Two people with an identical LDL-c figure can carry very different particle counts. The standard panel doesn’t see that difference. A fuller investigation does.

There is a second factor a standard panel leaves out entirely: lipoprotein(a), or Lp(a). It’s a particle you largely inherit, your level is set by your genes and barely moves with diet, exercise, or even the medication usually prescribed to lower cholesterol. That is precisely why it’s worth knowing: it’s an independent contributor to cardiovascular risk that the usual approaches don’t touch, and you can carry a meaningful amount of it while every standard marker reads normal. In the car analogy, it’s a structural characteristic of the chassis, not something a routine check is built to find.  You only need to measure this once in a lifetime to gauge your risk here.

Then there’s the state of the artery wall itself. Atherosclerosis isn’t only a matter of particles depositing; it’s an inflammatory process. A marker called HsCRP — high-sensitivity C-reactive protein — reads the level of low-grade inflammation in the body, and it isn’t part of a standard blood panel. On its own it proves nothing. Read alongside ApoB and Lp(a), it adds a dimension to the picture that any single number, viewed in isolation, would miss.

The real difference between a WOF and a service

None of these markers means much in isolation, and that is the heart of the distinction. A WOF checks items against a pass line: each one clears, or it doesn’t. A service reads how the parts are working together and where the wear is heading. One confirms compliance at a moment in time. The other reads a trajectory.

That is how we think about cardiovascular risk at Autonomy. We don’t read a marker in isolation; we read the pattern, and we tell you what it means. A normal cholesterol result and a high particle count tell two different stories about the same person, and the second only appears when you go looking for it.

How Autonomy investigates this

The sequence matters here, and it isn’t cosmetic: we investigate before we recommend, not the other way around. We measure ApoB, Lp(a), inflammatory markers and the rest of the cardiovascular picture.

We interpret what that pattern means for your particular configuration, your markers, not a population average.

Only then do we talk about what, if anything, is worth changing.

The aim is not to replace the WOF. The standard panel does what it is designed to do, and it does it well. The aim is to add the service: the fuller inspection of an asset you intend to keep for decades, your body. More than 650 New Zealanders have now completed an Autonomy clinical programme.

A sensible next step

If a peer’s diagnosis has moved the question from abstract to specific, the sensible next step isn’t to panic, and it isn’t to wait for the next routine appointment to come round. It’s to find out what your own picture actually shows.

That’s what the Discovery Consultation is for: a 30 minute conversation ($249, no obligation) about where you stand, what’s worth investigating in your case, and whether a fuller investigation makes sense for you. A clear-eyed look at the difference between nothing has failed yet and here is what’s worth knowing.

You service the car you plan to keep. The same logic, applied to the body, is simply how drift gets caught before it becomes a diagnosis and an expensive repair job that could have been avoided.
