The most dangerous thing about cardiovascular disease is how quiet it is.

The average heart attack doesn’t arrive out of nowhere. It arrives after years of arterial buildup, slowly rising blood pressure, and simmering inflammation — none of which produce symptoms until something finally breaks. By the time a person feels chest pain, the underlying problem has typically been developing for a decade or more. The heart attack feels sudden. The disease was not.

This is not fatalism. It’s the opposite: because cardiovascular disease builds slowly, there’s a substantial window to see it coming — if you’re using tools sensitive enough to find it before it announces itself.

What AI Is Changing About Cardiac Detection

For most of medical history, detecting arterial plaque meant waiting for symptoms or a cardiac event. That changed meaningfully with the coronary calcium score — a brief CT scan that detects calcified deposits in the coronary arteries. It can be done at most radiology facilities for a few hundred dollars, and if you’re over 40 with any cardiac risk factors, it’s worth asking for at your next appointment.

But the calcium score has an important limitation. It detects calcified plaque — the older, more settled kind. The plaque more likely to rupture and cause a sudden event is softer, non-calcified, and invisible to that scan. Peter Attia, MD,renowned longevity physician notes that roughly 2–3% of people with a “perfect” calcium score of zero actually have high-risk plaque that only becomes visible with more detailed imaging.

A CT coronary angiogram (CCTA) is the scan that reveals that softer plaque. A company called Cleerly now applies artificial intelligence to CCTA images to map the coronary arteries in three dimensions — measuring plaque not just by presence, but by type, volume, and composition. The AI has processed far more cardiac images than any individual radiologist ever will, and the analysis it produces goes well beyond what human review can reliably extract. The calcium score tells you the house is old. Cleerly’s analysis tells you where the structural problems actually are.

The Blood Markers That Actually Predict Risk

The standard cholesterol panel — total cholesterol, HDL, LDL — has been the primary cardiovascular screening tool for 50 years. It’s not useless, but it misses a meaningful portion of people who will have cardiac events, and it mislabels some people as high-risk who aren’t. Two markers give a substantially sharper picture.

ApoB counts the number of atherogenic (plaque-building) particles circulating in your blood. Standard LDL measures their weight rather than counting them. In most people these track together — but in people with metabolic dysfunction, ApoB can be significantly elevated while LDL looks normal. Those are exactly the people who slip through standard screening. ApoB is a routine lab test, widely available, and rarely ordered in a standard annual physical.

Lp(a) — pronounced “L-P-little-a” — is a lipoprotein determined almost entirely by genetics. An elevated level roughly doubles cardiovascular risk independent of everything else: cholesterol level, blood pressure, diet, exercise. About 1 in 5 people carry it elevated; most have never been tested. Knowing it doesn’t give you anything to change directly — no diet or current drug reliably lowers it — but it changes how aggressively you manage every other risk factor you can control. It’s a single blood test, done once in a lifetime.

hs-CRP (high-sensitivity C-reactive protein) measures systemic inflammation. Inflammation is the mechanism that turns stable arterial plaque into something that ruptures. An elevated hs-CRP is an independent predictor of cardiac events, and the interventions that lower it — improved sleep, regular exercise, reduced refined carbohydrates — are the same ones that improve nearly everything else.

A Note for Women

Cardiovascular disease kills more women than all forms of cancer combined. Yet surveys consistently show that fewer than half of women identify it as their greatest health threat. The symptoms can present differently in women — fatigue, jaw or upper back pain, and nausea rather than the classic chest pressure — and standard risk-prediction tools systematically underestimate risk in women with certain risk-factor profiles. Heart disease deserves the same proactive attention from women as any cancer screening, and arguably more.

The Practical Steps

At your next appointment, ask for three things: a coronary calcium score, an ApoB level, and an Lp(a). All three are standard orders that any physician can write. If your calcium score comes back at zero but you have risk factors — family history, elevated ApoB, elevated hs-CRP, or a history you’ve never fully investigated — ask whether a CT coronary angiogram is a reasonable next step.

The goal isn’t a perfect scan. It’s an accurate picture of where you actually stand, so any course correction happens on your schedule rather than the disease’s.

Finding a Physician Who Practices This Way

Not every physician will order these tests, know the distinction between calcified and non-calcified plaque, or be familiar with tools like Cleerly. Longevity and preventive medicine physicians work with this framework as their primary orientation — it’s the medicine they trained to do, not an add-on to a busy general practice.

FindLongevityMD.com lists clinics and physicians across the United States who specialize in this kind of proactive, prevention-first care. You can search by state to find someone near you.

If you’d like help thinking through your specific cardiovascular risk picture — what tests make sense given your personal and family history, how to interpret results you already have, or how to have a productive conversation with a physician who may not be familiar with this framework — I offer individual consultations for this.
