What Is a Coronary Artery Calcium Score?

The Coronary Artery Calcium (CAC) Score is a specialized CT scan measuring calcium buildup (plaque) in your coronary arteries. These arteries supply oxygen-rich blood to the heart muscle, and calcified plaque is a key indicator of coronary artery disease (CAD), even in individuals with no outward symptoms.

By calculating your calcium score, we can estimate your long-term risk of a heart attack and tailor a prevention plan that matches your unique cardiovascular profile.

Why the Calcium Score Matters

Many heart attacks occur in people with no apparent symptoms. The CAC test is one of the most effective tools for early detection of heart disease—especially for those at intermediate risk. The results empower you and our cardiologist to make more informed lifestyle, medication, and follow-up care decisions.

Who Should Consider This Test?

You may benefit from a coronary artery calcium score if you:

  • Are age 40–75 with intermediate risk for heart disease
  • Have a family history of early heart disease
  • Have high blood pressure, high cholesterol, or diabetes
  • Are a smoker, or former smoker
  • Are unsure whether you need to begin statin therapy
  • Have no symptoms but want a more accurate picture of your heart health

This test is not ordinarily recommended for those with known heart disease or very low/no risk.

What to Expect

  • Fast & Noninvasive: The scan takes just 5 to 10 minutes and involves no needles, dyes, or injections.
  • No Preparation Required: You can eat, drink, and take your medications as usual unless told otherwise.
  • Painless Experience: You’ll lie flat on a table while the CT scanner captures high-resolution images of your heart.

Once complete, your results will be reviewed by a cardiologist and discussed with you in a follow-up appointment.

Understanding Your Score

The calcium score is expressed as a number:

  • 0: No detectable plaque. Low risk of heart disease.
  • 1–99: Mild plaque buildup. Low to moderate risk.
  • 100–399: Moderate plaque buildup. Increased risk.
  • 400+: Extensive plaque buildup. High risk of heart attack or other cardiac events.

A higher calcium score indicates more extensive calcified plaque in the coronary arteries, signaling an increased risk of heart attack or other cardiac events. It highlights the need for proactive cardiovascular care, including lifestyle changes, possible medication, and regular follow-up to help reduce future risk and protect long-term heart health.
