Does anyone know the Agatston Coronary Calcium Score Guidelines?
Does anyone know the Agatston Coronary Calcium Score Guidelines?
I recently had a CT Angio Heart, and Coronary Artery Scan done. The results included my Agatston Calcium score of 1055.8 and that it was in the 99 percentile for a female of 81 y.o. Agatston guidelines shows any score over 300 is a higher risk for severe coronary artery disease, but yet I am in the 99 percentile for a woman of my age??? What does that mean??? Any comments would be appreciated.

I means there is a lot of calcified plaque in your coronary arteries. Check with you cardiologist. I had a 1325 score before my bypass operation.

Oh, wow!!!
I am following the Agatston coronary calcium guidelines that says anything over 300 means there is extensive calcium build up and a significantly higher risk for coronary artery disease. I will ask my cardiologist, but also see if the American Heart Association has anything posted. Thanks for your input.
99th percentile means you have more plaque than 99% of women your age.

Thanks!
Gives me more information to ask my cardiologist.
Surprised that the CT scan summary did not raise it in more detail.
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?

Thanks for the Agatston info.
The Agatston score was included in the results of a CT scan of my aortic aneurysm, stomach, and pelvis. The size of my aneurysm was 4.1 cm which is a concern because my previous scan in February 2026, the size was 4.8 cm. It was 4.6 cm in November 2024. My cardiologist asked a thoracic surgeon to review the films of the last 2 scans and I am currently waiting for the surgeon's opinion. I am calling my cardiologist to ask what he recommends on the Agatston score since it seems to have been overlooked in the concerns about the aneurysm sizes.
