The one blood test that can predict heart disease before it starts

Most people think heart attacks just happen out of nowhere. One day you feel fine — the next, you’re in an ambulance.

But heart disease doesn’t strike overnight. It builds up quietly for years, and one tiny thing in your blood can reveal it long before symptoms show up. That thing is called ApoB. Doctors used to focus only on cholesterol. But new research shows it’s not just “good” and “bad” cholesterol that matter. It’s ApoB, a protein that carries cholesterol through your blood, that tells the real story.

Why ApoB matters more than you think

Imagine your arteries are highways, and ApoB particles are trucks carrying cholesterol.
The more ApoB trucks you have, the more traffic jams — and those jams can damage your arteries.

Over time, this damage turns into plaque, which clogs your arteries and raises your risk of heart attack or stroke.

Scientists like Dr. Peter Attia and Dr. Andrew Huberman say the evidence is clear:

• More ApoB = higher chance of artery damage.
• Lower ApoB = healthier arteries and longer life

‍

And here’s the kicker: even if your regular cholesterol test looks “normal,” your ApoB might still be high.

That’s why doctors now see ApoB as one of the most important numbers for predicting heart disease — even more than LDL.

So why aren’t we testing everyone for it?

Medicine still tends to wait for problems to appear before taking action. But that’s like waiting for a smoker to get lung cancer before telling them to quit.

If something causes heart disease — and we can measure it — why not check it early and fix it fast? That’s the whole point of testing ApoB.

How to find out your ApoB level

You don’t need to wait for a doctor’s referral or a hospital appointment to get this test. Labs like Private MD Labs let you order an ApoB test directly.

It’s one of the most affordable advanced heart tests available, and you can get results fast. That means you can know your real heart risk and take action long before any warning signs appear.

A simple step toward a longer, healthier life

Here’s the truth: you can’t change your genes, but you can change your numbers. If your ApoB is high, you can work with your doctor on lifestyle changes or treatment to bring it down — before your arteries ever get damaged.

Because when it comes to heart disease, the best time to act is before it starts. And knowing your ApoB level is the easiest way to start.
