“Seeing the CAC score prompts more aggressive treatment, with patients and doctors focusing on improving cholesterol and other risk factors.” — Joel Kahn, MD

Heart disease doesn’t wait for people to hit 60, so why should we? Joel Kahn, MD, a holistic cardiologist, recently posted an Instagram Reel that sheds light on why every patient, no matter their age, could benefit from a coronary artery calcium (CAC) score, especially those with risk factors.

Dr. Kahn points to a powerful study from Australia that underscores the importance of this test.^[] He explains that when patients and their doctors see the results of a coronary calcium scan, “Seeing the CAC score prompts more aggressive treatment, with patients and doctors focusing on improving cholesterol and other risk factors.”

This is where the CAC score really stands out—it gives us a clearer picture of heart health, even for younger patients who might seem fine but have hidden plaque buildup.

For instance, a 40-year-old with a family history or lifestyle risks like smoking might not show symptoms, but could have significant coronary plaque that isn’t detected by a simple blood test.

The value of CAC scoring goes beyond just identifying the presence of heart disease. It’s about getting ahead of the game.

"If you repeat the coronary CT angiogram a few years later, you’ll see less plaque because everyone knows the truth—you’ve got heart disease, even if you’re asymptomatic."

— Joel Kahn, MD

Early detection allows us to intervene before patients experience major events like heart attacks or strokes. By addressing cholesterol and plaque buildup early on, we can actually reduce the amount of plaque over time, improving long-term heart health.

This approach changes the way we think about heart disease. Instead of waiting for symptoms or a critical event, we’re taking proactive steps to protect our patients.

And the best part? It’s simple. A non-invasive test like CAC scoring can reveal information that allows for earlier, more targeted treatment—whether it’s lifestyle changes or medications like statins.

Dr. Kahn’s message is clear: heart disease doesn’t care about age, and neither should we. If we can identify patients at risk—even before they show symptoms—then we’re in a better position to treat them effectively. Whether your patient is 35 or 65, a CAC score could give you the full picture and help prevent future heart attacks or strokes.
