Hi @ewei6911

Mayo Clinic has an overview of the Coronary Artery Scan you are referencing. I will include the link and also copy the “Results” section that addresses the Agaston Score.

Keep in mind that results shouldn't be used as a single sign of your overall health and risk of heart disease. The information from the scan should be reviewed with other health information.

RESULTS
Coronary calcium scan results are usually given as a number. The number is called the Agatston score. The score is the total area of calcium deposits and the density of the calcium.
- A score of zero means no calcium is seen in the heart. It suggests a low chance of developing a heart attack in the future.
When calcium is present, the higher the score, the higher the risk of heart disease.
- A score of 100 to 300 means moderate plaque deposits. It's associated with a relatively high risk of a heart attack or other heart disease over the next 3 to 5 years.
- A score greater than 300 is a sign of more extensive disease and a higher heart attack risk.

The test score also may be given as a percentage. The number is the amount of calcium in the arteries compared to other people of the same age and sex. Calcium scores of about 75% have been linked with a significantly higher risk for heart attacks.

Would you share more about what led you to get a CT Angio Heart and Coronary Artery Scan done? Also, what is next?
