Coronary Calcium Score: A Simple Heart Test That Can Save Your Life

CT Scan of the Heart

A coronary calcium score test detects early heart disease before symptoms appear. Learn what the results mean and why proactive screening matters.

What Is a Coronary Calcium Score Test?

A coronary calcium score test is a specialized CT scan that measures calcium buildup in the arteries of the heart. Over time, calcium develops as plaque hardens, narrowing blood vessels and increasing the risk of a heart attack. The test is quick, non-invasive, and does not require needles or contrast.

In healthcare, one reality remains consistent: heart disease often progresses silently. This test helps uncover risk early, when prevention is still highly effective.

Why the Calcium Score Matters for Heart Health

Heart disease remains the leading cause of death in the United States. According to the Centers for Disease Control and Prevention (https://www.cdc.gov/heart-disease/about/index.html) nearly 1 in 5 deaths is related to cardiovascular disease. Early detection plays a critical role in changing that outcome.

A calcium score can:

  • 🫀 Reveal hidden plaque before symptoms develop
  • 📊 Clarify cardiovascular risk beyond routine blood work
  • 🛡️ Support timely lifestyle or medical intervention

Research supported by the National Institutes of Health (https://www.nhlbi.nih.gov/news/2023/coronary-artery-calcium-scores-may-improve-heart-disease-risk-predictions) confirms that coronary calcium scoring improves cardiovascular risk prediction beyond cholesterol testing alone.

Taking a Proactive Step: My Personal Experience

I recently had a CT coronary calcium score done as part of my own preventive health screening. Like many people, I felt well and had no warning signs. When the results showed a higher-than-expected score, I took the findings seriously.

I met with my family physician, reviewed the results together, and received a referral to a cardiologist

for further evaluation and workup. That single screening test prompted earlier action, additional testing, and a clearer plan for protecting my heart health.

This is what proactive healthcare looks like—using information wisely and acting early, rather than waiting for symptoms to appear.

Understanding Your Calcium Score Results

What Is a Normal Calcium Score?

  • 0: No detectable plaque; very low short-term risk
  • 1–99: Mild plaque; early heart disease
  • 100–399: Moderate plaque; increased cardiovascular risk
  • 400+: Extensive plaque; significantly higher heart attack risk

Individuals with very high CAC (≥1000) are a unique population at substantially higher risk for CVD events, non-CVD outcomes, and mortality than those with lower CAC, with 3-point major adverse cardiovascular event rates similar to those of a stable treated secondary prevention population. https://pubmed.ncbi.nlm.nih.gov/33650435/#:~:text=The%20study%20found%20that%20people%20with%20CAC,and%20mortality%20than%20those%20with%20lower%20CAC

Who Should Consider a Calcium Score Test?

This screening is especially helpful for adults:

  • Over age 40
  • With a family history of heart disease
  • With diabetes, high blood pressure, or high cholesterol
  • Seeking clarity beyond routine blood tests

Frequently Asked Questions

Is Calcium Score worth it?

Yes. The American College of Cardiology (https://www.acc.org/Latest-in-Cardiology/ten-points-to-remember/2018/07/23/13/39/Coronary-Calcium-Score-and-Cardiovascular-Risk) reports that CAC scoring has emerged as a widely available, consistent, and reproducible means of assessing risk for major cardiovascular outcomes, especially when planning primary prevention interventions, such as statins and aspirin. 

Does insurance cover calcium scoring?

Coverage varies by plan. Many individuals choose this test because the out-of-pocket cost is often modest compared to the value of early detection.

Can risk be reduced after a high score?

Yes. Lifestyle changes, medical therapy, and specialist guidance can significantly reduce future cardiovascular risk.
