Input Age, Race + Sex, and (optional) Observed Agatston CAC Score
This calculator provides tools to help interpret CAC scores for adults aged 30-45 years.
Coronary artery calcium (CAC) is a direct marker of calcified plaque in the blood vessels that supply the heart. The amount of plaque can be measured with a CT scan of the heart known as a CAC exam or calcium scan.
CAC is a risk factor for cardiovascular disease. A higher CAC score means higher risks of heart attack and stroke.
By entering an age, sex, and race, we can calculate the probability of having any CAC. This may help to determine when and in whom to do a CAC exam.
By adding a CAC score, we can calculate a CAC percentile. This tells us how high a CAC score is compared to others of the same age, sex, and race (i.e. relative risk). It can also help with estimating lifetime risk, since most individuals’ CAC scores naturally grow along their percentile unless interventions are taken to reduce plaque growth.
Talk to your cardiologist. In addition to lifestyle modification and risk factor reduction, you may be a candidate for medications to reduce your risk of heart disease.
